    This is incredible and why BoostAddict.com picked the new Audi 2.5 TFSI I5 as its 2017 engine of the year. Iroz Motorsport made their way out to Famoso Raceway in California this past weekend with their Audi RS3 sedan and almost broke into the 9's. They managed a 10.090 @ 142.42 on a 1.602 60 foot. This is on the stock motor and stock DSG dual clutch transmission. It's almost too good to be true. Keep in mind also it is very warm in Southern California right now with temps over 90 degrees yesterday. Density altitude was in the 700 foot range at the time of the run. As for what was necessary Iroz used their custom Xona Rotor turbocharger upgrade and pulled some weight from the car. The intercooler and downpipe are Iroz pieces but the airbox and exhaust after the downpipe is stock. What do you even say?

    Thanks a lot feminists. You have even managed to get your hideous tentacles into the pinnacle of motorsport to strangle to death an aspect fans love. Those fans are predominantly men so you can understand why Formula 1 would be a target for the modern day feminist. In our ever more so politically correct society attractive women 'cheerleading' at sporting events are apparently a no-no: Yeah, right. Super hot women around hundreds of millions of dollars of world class race cars in locales around the globe piloted at incredible speeds to determine a victor somehow doesn't appeal any longer. What should these women be replaced with? Perhaps some 300 pound blue haired feminist lecturing the audience on how race cars are racist because 'race' is right there in the name? What do the women who just lost their jobs think? Say what you want about Bernie Ecclestone, he wouldn't have caved to this absurdity. Source

    Well, the new BMW M5 is the raw muscle champion out of the newest sport sedan crop. It will beat all of it rivals in a drag race and do so rather easily. It certainly helps that BMW has the displacement advantage on everyone except for Cadillac and Jaguar. The thing about Cadillac and Jaguar is that they are not running turbocharged powerplants. The previous generation F10 M5 was heavily sandbagged in output. One can only imagine what the real output of the F90 twin turbo S63B44T4 V8 is. If we were to guess, it's making over 600 horsepower to all four wheels stock. Yes, more power at the wheels than it is rated at the crank. There is no other way to explain it hitting 129 miles per hour of trap speed through the 1/4 mile even if it is a magazine time. The 10.9 elapsed time should be easily replicated on the dragstrip by owners. All wheel + automatic = easy launches. The new M5 is not only the quickest and fastest car in its class it is also the lightest. Well, at 4288 pounds it is the lightest all wheel drive sedan. The Cadillac CTS-V is the overall lightest in the class at 4108 pounds. Congratulations BMW. You built the best 4-door dragster in the world.

    AC Fabrication announced this bottom mount twin scroll N54 manifold a while back and now we have some testing results courtesy of BMS. The numbers are strong with a good looking curve on an unnamed BorgWarner EFR turbocharger. Here are the details from BMS: Payam finally got his car back together last week and sorted out the usual various gremlins that come from an eBay motor swap. So we took the opportunity today to do a little dyno testing with it. The setup is: 1) Stock junker motor 2) ACF twin scroll bottom mount kit, running a relatively small EFR turbo. Payam tells me its roughly equivalent to a PTE 6266. They put an 8psi WG spring on it as a starting point. 3) Fuel IT Stage4 fuel system, 100% E85, random China intake manifold. 4) All the rest of the usual suspects for bolt ons. 5) Tuned via JB4 using off the shelf software, settings, and back end flash map. Surprisingly virtually no actual tuning work was needed to get this thing up and running pretty well. Default port injection settings too. JB4 is doing all the work on that front in the back end as you toggle through different boost profiles. 6) No antilag used, 4th gear runs, ~75f temps, etc. Anyway we took the car through it's paces on the dyno. I found the lowest and highest maps the most interesting. On the WG spring at around 8psi it made ~400whp. Then on the other end with the WG spring completely maxed out (WGDC close to 100%), it put down an impressive ~740whp. Anthony and Payam were both at the dyno with me and there was some debate between us as to whether the spring is maxed or the turbo itself. Hopefully we settle that soon. Under real world load the car spools and drives really nicely, and no doubt if someone cared to optimize the tuning to the more aggressive side of things there is power and spool to be had. Personally I'm just finally glad this car is done so Anthony can start working on our white car's bottom mount turbo kit. Got Payam's car back on the dyno today with a 12psi WG spring and a new version of the EOS intake manifold. We were hoping to eek a little more power out up top and did but at the slightly higher boost levels we had a lot more timing instability. We also accidentally did a 35psi midrange run (duty bias wasn't adjusted for tighter spring)... Hello 800wtq+ on a stock motor!

    A BMW drag car built in South Africa? That is what you have here from Budler Motorsport. They chose the classic S38 inline-6 to be the heart of the drag car and BimmerBoost thinks that is a great choice. The motor tops our list of all-time M engine afterall. What kind of power is it making? Good question. Quite a bit considering the car is running mid 7's at over 185 miles per hour. Details are somewhat hard to come by on this build as specifications are not provided and there is not exactly a ton of media out there on it. What we know is the quickest run is Budler Motorsport's 7.49 @ 298 km/h at Tarlton International Raceway in South Africa. Beyond that, BimmerBoost compiled what media there was to find on the car which is posted below. A shame there is not more info on it.

    No shame here. The BMW M2 is simply nowhere near the level of the Audi RS3. Despite the BMW's N55B30T0 powerplant offering half a liter of displacement and an additional cylinder over the Audi's 2.5 TFSI it gets clobbered. We all know the M2 is neutered to keep it from stepping on the toes of its big brothers but the RS3 sedan is more than a match for anything BMW has in the lineup. Seriously, it is running 10.0 flat at over 140 miles per hour on the stock internals. Built motor F80 M3's or F82 M4's would have their hands full competing against that. Here is what the two cars in the video below bring to the table: 2017 BMW M2 ER Catless downpipe Wagner Evo Comp 2 Intercooler ER hot and cold chargepipes Dinan intake Dinan resonator delete and muffler Pure turbo inlet Fuel it LPFP Bootmod 3 Stage 2 OTS 2018 AUDI RS3 IROZ Motorsports Front mount intercooler IROZ Motorsports Downpipe + midpipes Custom Code stage 2 91 octane software Stock everything else. From a stop the M2 gets crushed. From a roll it is slightly closer but it still gets crushed. The bottomline is the RS3 is on another level with bolt ons let alone with turbo upgrades.

    The M135i is not a real M car. They acknowledge this in the video thankfully or somebody's head at BimmerBoost would likely be exploding. The thing is, when you make the point of what is or is not a BMW M car how do you leave out that M stands for Motorsport? Why is that a big deal? Because the stock E92 M3 they bring to this drag race has the only engine that won in Motorsport doing things like going around a track. It is the oldest M there but would clean up with the other two around the track. When did the measure of an M car become drag racing? Well, around the same time BMW went turbo and suddenly everyone cared more about power than the all around package BMW M was once known for. Well, whatever, here's a 1/2 mile race by Autocar. You already know before it begins the F10 M5 will win. The M3 not only has a smaller motor but no turbos. No chance. Give it a blower and now we have something interesting to watch. The M135i (thanks a lot for putting the letter on M on everything BMW) has a tuned N55. Why they bothered with giving it a limited slip differential over a turbo upgrade is anyone's guess. They could have really opened some eyes and done something different if they showed an M135i topping an M3 and an M5. Oh, and would some acceleration data have killed them? Enjoy:

    Well, that didn't take long. Actually, it took a little over a week. The new C7 generation Chevrolet Corvette ZR1 is the production car lap king on the VIR (Virginia International Raceway) Grand Course West layout. Chevrolet obviously saw the opportunity with Car and Driver having tested the Ford GT to make a splash and to their credit this is indeed massive spalsh. For the Corvette ZR1 to one-up a $500k supercar with a mid-engine layout for a fraction of the price is incredible. It also diminishes the Ford GT and certainly makes the vehicle look overpriced for what it is delivering. So what is the new record? 2:37.3. That doesn't just beat everyone else. It blows them so far away you wonder if they were even trying: Holy crap! A 5.7 second difference? Admittedly, driver skill played a role here but wow... wow!

    This just keeps getting better and better. As you know, feminists forced Formula 1 to remove the grid girls we all know and love. What are they replacing grid girls with? Grid children. Yes, seriously, that is Formula 1's move. The fired grid girls are organizing a protest on Facebook which is receiving tremendous support. The question now is, will feminist heads explode trying to figure out which side to support? On one hand, you have the feminists that forced Formula 1 to get rid of the girls saying they were being exploited. On the other hand you have the grid girls saying they chose the job on their own and enjoyed doing it without any feeling of exploitation. This is peak feminism. Women destroying other women over perceived injustice which the women who are supposedly suffering from this injustice say they are exercising freedom of choice. Somebody pass the popcorn. Source

    Wow! Sean Ivey of Ivey Tune was able to get a ton of power out of this Infiniti Q50 VR30DTT. Keep in mind this is the base Q50 3.0T and not the Red Sport version although the turbochargers are basically the same between the two. What make this even more impressive is the car is on pump gas and has bolt on modifications. BoostAddict contacted Ivey Tune and is waiting on the full graph which will be edited in once received:

    A 2:38.62 laptime around VIR's (Virginia International Raceway) Grand Course West in the new For GT is spectacular. It's much quicker than the 2:43.0 laptime Car and Driver was able to set. Yet it still trails the VIR Grand Course West champion the C7 Corvette ZR1 and its 2:37.3. The new time from professional driver Billy Johnson looks better but the GT is still being dominated by over a second by a much cheaper Corvette: It is difficult to look at the Ford GT as anything other than a letdown in 2018 performance car terms considering the hype and price point. It certainly does well in its professional racing classes though.

    Another day another N54 turbo upgrade with Chinese sourced housings. Introducing Kott Turbo Works which is based out of Illinois and offering various N54 turbo rebuilding and replacement services along with a turbo upgrade option. You may recall a rather interesting thread on BimmerBoost that highlighted a certain turbo vendor going to cheap Asian cast housings and the problems that came with that switch. Make no mistake, there is only one reason to go to China for housing production and that is to lower costs (upping profit margins), not improve quality. You can make the decision yourself as to what you want to run but it certainly seems those offering upgrades utilizing the factory housings are more reliable over the long term and higher quality. Kott calls their upgrade the KTB001: Hybrid TD03 turbochargers front and rear for BMW N54 engine with billet compressor wheel. 43.4mm inducer, 56mm exducer billet compressor wheel 41.2mm exducer 47mm inducer turbine wheel 44mm inlet inside diameter New high strength stainless steel wastegate bushings Vanadium alloy cast turbine housing 1000 Celsius rating Capable of producing 600+ horsepower with proper tune on E85 fuel 500 horsepower on 91 octane pump gas High performance journal and thrust bearings VSR balanced No core charge 1 year warranty $1400.00 This is the current state of the N54 market. To do a high end motor build and turbo setup with proper tuning will run more than what the cars cost these days. The market is flooded with kids who want a ton of horsepower for bargain bin prices. Many of whom just buy whatever is the cheapest whether it comes from a scammer or if it is low quality junk that cracks. You can also look at it as the N54 platform is a tuning value rather than as it experiencing a quality drain. The truth is probably somewhere in the middle.

    This image leaked out from a garage showing what appears to be the undisguised rear end of the upcoming 992 generation Porsche 911. Based on previous covered up spy photos this seems to be the back of the 911 Carrera S. The image was since deleted from the social media account that posted it which means this is likely legitimate. The 992 is shaping up well.

    Nice of FVD to finally join the 991.2 3.0 tuning party but they are definitely late and not bringing anything interesting to the table. First of all, when you launch a tune you need to prove the output you are making. FVD does not. No graph, no acceleration figures, nothing. The 0-60 claim they provide is slower than stock test figures. Who writes this stuff for FVD? It's terrible: FVD Software Power Gains: Max. Power - 335 kW (455 HP) @ 6500rpm Max. Torque - 580 Nm (428 lb.-ft.) @ 1900rpm Max. Speed - 305 km/h (189 mph) Max. RPM - 7900 rpm Acceleration 0-100 km/h (0-62.5 mph)* - 4.0s They also claim to bump the redline to 7900 rpm and state the stock car revs to 7800. It doesn't. It revs to 7500. So what we have are several mistakes, no proof, and consumers just having to take their word for it. FVD's launch makes GIAC's release look stellar in comparison. Even if FVD is hitting their 455 crank horsepower target the PorscheBoost.com project 991.2 hit that number to wheels with Gintani tuning months ago. Way too little, way too late from FVD.

    This is awesome news! The Las Vegas Motor Speedway dragstrip is a top notch location and one of the NHRA's favorite locales. What is better than combining Vegas and world class Motorsport? Well, how about taking it to the next level with four-wide drag racing? The Las Vegas Motor Speedway dragstrip is currently expanding to four lanes. Speaking as someone who ran at the previous track configuration, I can't wait to try out four-wide racing on my own. Take a look at the video below to get an idea as to what four-wide NHRA action is like. Now if they could just do something about that desert weather...

    Very impressive numbers here from a Porsche 997.2 generation Turbo S. Especially when you take into the account the 3.8 liter direct injected motor is completely stock, the fuel system is stock, and the PDK dual clutch transmission is stock. You keep launching like that and it likely won't hold together for too much longer but hey it sure is impressive.

    There are still many questions here but apparently this is the new MKV Toyota Supra. This info comes from Japan's Best Car Magazine which says the Supra has a 3.0 liter turbocharged inline-6 with 335 horsepower and 332 lb-ft of torque. That sure sounds like a BMW B58 powerplant as Toyota doesn't have a modern turbo I6 in a street car we are aware of. Only one transmission choice is mentioned which is an automatic. Somehow this doesn't feel like a proper homage to the MKIV Supra.

    This is a battle we have all been waiting to see. The Audi RS7 4.0 TFSI V8 gets a ton of credit and deservedly so. There were those who mocked Audi for providing the smallest twin turbo V8 in last generation's mid-size sport sedan market yet Audi's potent mill proved to be the strongest tune only despite its displacement disadvantage. Amusingly, Mercedes-AMG went to a similar style V8 for the new W213 E63 yet it isn't as strong with a tune as the now old RS7. Obviously, the 4.0 TFSI is stout with RS7's running 10.2's in the 1/4 mile at 133+ which is the stock turbo record in the USA. The RS3 is already beating that. Easily. The little brother barely entered the market and is already kicking ass and taking names. Now what is interesting in the video here is you have an RS7 on upgraded Garrett turbochargers. You will notice there are not really any successful upgraded turbo RS7's running around and this RS7 is said to still be under development. The RS3 has a big turbo setup from Iroz on E85. What happens? The RS3 spanks it. The guy in the RS7 needs his eyes checked if he thinks that was close. Say what you want about having a V8 carrying 1000 less pounds makes a huge difference. So does that dual clutch transmission in the RS3. From a 35 mph roll it's ugly too. The RS3 runs away. Why haven't big turbo RS7's shown well? Who knows. Big turbo RS3's are already crushing them though and it's not likely to get any closer from here on out as 2.5 TFSI tuning accelerates.

    We all know the McLaren 720S is spectacularly fast. McLaren raised the bar to a level the competition will struggle to find for years to come.

    Some people are surprised to learn that the Porsche 991.1 Turbo and S models never broke into the 9's with bolt ons unlike the 997.2 that preceded it. Additionally, that the 991.1 Turbo and S have the same turbochargers with output only differing due to different software tuning. That changed with the 991.2 Turbo S which received larger turbos than the 991.2 Turbo. The new turbos pay dividends: A very impressive run with just bolt on modifications: ByDesign Intercoolers Kline exhaust IPD Plenum Stock turbos Gintani tune The 1.510 60 foot is impressive and shows how well the 991.2 platform launches. Excellent work and congratulations on being the first bolt on 991.1/991.2 Turbo or Turbo S in the 9's.

    This is the rumor circulating but it is based on nothing more than the word of a magazine editor. It is entirely possible he is correct but it is also entirely possible he is wrong and there is nothing substantive from Porsche to support his position. The naturally aspirated flat-6 may be at the end of its lifespan as squeezing out power is becoming increasingly difficult. The new 991.2 generation Porsche 911 GT3 RS only gets a few horses on top of the standard GT3 model. They both have the same displacement at 4.0 liters. It may be due to this difficulty of extracting more power and hitting a displacement wall that is forcing the change. Most experts agree though that Porsche can take the GT3 flat-6 to at least 4.2 liters. A turbocharged GT3 is redundant, isn't it? Isn't that just a GT2? Call us skeptical but if Porsche was to build their last naturally aspirated 911 they would have let us know. There would be big fanfare. There would be a mad cash grab with some special model to put an exclamation point on the legacy of the naturally aspirated flat-6. The idea of the NA motor dying with the 991.2 generation 911 just feels like clickbait. Source

    Congratulations are in order to BigBoost Turbo! You have read about their B58 turbo kits and know they have set various power records on the platform. Well, you can add being the first to break the 600 whp barrier to their list. Their F22 M40i hit 613 horsepower to the wheels with the following mods: M240i B58 93 octane + full concentration octane booster BigBoost Throttle Body Injection (#24 jet) BigBoost Stage 3 turbo with 5964 turbo Map 7 70 boost additive and 20 fua Stock catback exhaust BigBoost new wastegated turbo manifold BMS V.8 T12 firmware BigBoost 2.5" upper chargepipe BMS Intake This is done with 23 psi of boost thanks to a new manifold/wastegate design. Oh, and on the stock internals. So where do we go from here? No doubt BigBoost will the be the company that will continue to push the platform forward. Fantastic work.

    It is interesting to see BMS (Burger Motorsports) enter new markets and adapt their JB4 tuning hardware to different platforms. Surprisingly, the Ford Raptor 3.5 Ecoboost make for a fairly easy JB4 install. Why is that? There are similarities to the BMW market: As stated in the quote no dynos just yet but the 3.5 Ecoboost responds very well to tuning. We'll have more details as the upgrade is finalized.

    As you know, the Audi RS3 is kicking ass and taking names. BMW has no answer for it but BMW does not have an answer for most performance cars these days. It seems BMW is considering an M2 Gran Coupe to compete with the RS3. Now, that poses an interesting entry into the segment. Why? Because the RS3 is all wheel drive with a dual clutch transmission. The M2 Gran Coupe would be rear wheel drive and have a manual option. That is where BMW traditionally shines. That is, by offering the best driver's car. The powerplant is a question mark. To put it simply, the Audi 2.5 TFSI is going to trounce BMW if they continue with the N55B30T0 from the F87 M2. Maybe a detuned S58 will be utilized? That would be the ideal BimmerBoost choice or else the M2 Gran Coupe will get embarrassed. Either way if BMW M intends to really offer a serious challenge to the RS3 they better bring the best they can do. Today's BMW will likely just be happy with entering a new niche though.

    Well this is freaking cool, isn't it? BimmerWorld ran at Pikes Peak last year in their Optima Batteries E92 M3. They did very well but the problem at Pike's Peak is elevation. Once approaching 13,000 feet that 400+ horsepower they had from the naturally aspirated V8 quickly felt like 300 horsepower. Forced induction is simply necessary to challenge at Pikes Peak in the top classes so BimmerWorld decided on turbo power. They are partnering with Motiv and Roush to build a closed deck N54 motor that should be good for 800+ horsepower hopefully at elevation: There are some interesting tidbits in there. Namely, a closed deck block with a dry sump oiling system and individual throttle bodies. To BimmerBoost's knowledge, nobody has done an N54 with ITB's yet. The proposed dual injection system to fuel this monster is seen in this CAD drawing: Now, they definitely have a long way to go to get this done by June but BimmerBoost will continue to update this thread with details as the build progresses. This is definitely one to watch.

    It is rather amazing when you think about it that Audi built such a monster with only five cylinders and 2.5 liters of displacement. The Mercedes-AMG C63 by contrast has an M178 4.0 liter twin turbo V8 so brute force should be on its side. Especially with a GAD Motors ECU tune on top. The RS3 also has a tune and is said to be at about 450 horsepower. So what do we learn? Well, for one, a rear wheel drive V8 AMG sucks to launch on wet tarmac. It's pointless really. The all wheel drive RS3 runs away and there is no chance for the C63. Eventually a run from a roll is done and it is surprisingly close. The C63 does edge it out. When they do a second run the C63 gets a better start and grip decisively pulling. Both cars are fantastic but the RS3 considering its positioning below the RS5 which is supposed to be the C63's rival definitely overachieves.

    Bear with us for a moment. The new 2018 G01 generation X3 M40i may be a better performance SUV buy than the BMW X5M. Crazy you say? Well, maybe not once you take into account what you get for the $55k asking price. The B58 3.0 liter turbo motor is a beast. It helps that it is moving a 4308 pound SUV. The X5M by contrast weighs almost 1000 pounds more. The B58 is also easily upgraded and we just saw an example top 600 horsepower to the wheels. That would make for a pretty good rival for an X5M with upgraded turbos, wouldn't you say? The X3 M40i pulls 'only' .85g on the skidpad compared to the X5M .98g but this is not a true 'M' suspension on the M40i. An upgrade here should have it doing the same if not better numbers. The point being the X3 M40i is half the price of an F85 X5M yet it is quite close in performance capability and when you factor in the aftermarket the lighter M40i is a potent package. In theory you could run circles around an X5M for a fraction of the cost. Imagine what the real 'M' version of the G01 X3 will do? VEHICLE TYPE: front-engine, all-wheel-drive, 5-passenger, 4-door hatchback PRICE AS TESTED: $65,245 (base price: $55,495) ENGINE TYPE: turbocharged and intercooled DOHC 24-valve inline-6, aluminum block and head, direct fuel injection DISPLACEMENT: 183 cu in, 2998 cc POWER: 355 hp @ 6500 rpm TORQUE: 369 lb-ft @ 1520 rpm TRANSMISSION: 8-speed automatic with manual shifting mode DIMENSIONS: WHEELBASE: 112.8 in LENGTH: 186.1 in WIDTH: 74.7 in HEIGHT: 66.0 in PASSENGER VOLUME: 99 cu ft CARGO VOLUME: 29 cu ft CURB WEIGHT: 4308 lb C/D TEST RESULTS: Zero to 60 mph: 4.4 sec Zero to 100 mph: 11.2 sec Zero to 130 mph: 21.0 sec Rolling start, 5-60 mph: 5.3 sec Top gear, 30-50 mph: 2.8 sec Top gear, 50-70 mph: 3.4 sec Standing ¼-mile: 13.0 sec @ 107 mph Top speed (governor limited, C/D est): 155 mph Braking, 70-0 mph: 158 ft Roadholding, 300-ft-dia skidpad: 0.85 g C/D FUEL ECONOMY: Observed: 19 mpg 75-mph highway driving: 29 mpg Highway range: 490 miles EPA FUEL ECONOMY: Combined/city/highway: 23/20/27 mpg

    The Porsche GT3 is among the most revered 911's and for good reason. It offers a race car experience for the road. The GT3 is arguably the closest facsimile to a road going GT3 class ALMS car ever sold. The problem? Porsche is approaching a displacement limit in the flat-6 motor. Due to this rumors abound such as the next generation 992 model becoming turbocharged. First of all, Porsche gets 520 horsepower from 4.0 liters in the 991.2 GT3 RS. That is a lot of power especially in naturally aspirated form from a six-cylinder. If you are into power, isn't that why the 911 Turbo and GT2 models exist? The GT3 should not be judged by horsepower but it is understandable that for it to remain competitive in the current climate more power is welcomed. Turbos are not the answer though. A GT3 with turbos is just, well, a GT2. The answer is eight cylinders. For some reason everyone in the media glossed over Porsche stating the 9A2 engine architecture currently employed in the 718 and 991.2 Carrera models can stretch to eight cylinders and was designed to be modular for this reason. Check it out, in theory this is what we could see: 9A2 Engine Cylinders: 4 Bore x Stroke: 91mm x 76.4mm Displacement: 1987cc Cylinders: 4 Bore x Stroke: 102mm x 76.4mm Displacement: 2497 Cylinders: 6 Bore x Stroke: 91mm x 76.4mm Displacement: 2981cc Cylinders: 8 Bore x Stroke: 91mm x 76.4mm Displacement: 3975cc Cylinders: 8 Bore x Stroke: 102mm x 76.4mm Displacement: 4994cc Up to five liters of displacement is available. Imagine for a moment a flat-8 GT3 with 5.0 liters, 600 horses, and a 9500 rpm redline. You don't need to go turbo. The other option is hybrid assist which Porsche already tested and has utilized in a Motorsport environment. The GT3 R Hybrid 2.0 produced 672 horsepower seven years ago. I'm sure with modern battery technology Porsche can further improve. Whatever route Porsche chooses going turbo is not the answer. The GT3 stands out precisely because it is not turbocharged. Keep it that way.

    It seems the 992 hype just can not die down and Porsche put up a press release to address some issues. They do not reveal anything earth shattering but seem to want to emphasize that the 911 will remain a 911. Why was this necessary? It seems the purists are already complaining about certain elements. The shifter is puzzling for sure. It seems Porsche is bracing enthusiasts for some big changes including electrification: “The new 911, too, will be the best 911 of all time.” We'll be the judge of that, thanks. There’s an oft-repeated anecdote from 1990: the setting is a technical seminar in Berlin for engineers in the automotive industry. During a break, two participants are talking about the Porsche 911. One of them, a leading engineer for a major carmaker from southern Germany, says: “If I had to improve that car, I wouldn’t have the foggiest idea. I think it would be incredibly difficult.” The other, a leading engineer at Porsche, regards his counterpart with incredulity—and says nothing. It still elicits a chuckle from August Achleitner today when he thinks of his befuddlement back then in Berlin. Further developing the Porsche 911 has been his job for almost twenty years. Achleitner is the director of the 911 model line and is thus something like the keeper of the Porsche grail. “The heart of the company,” he calls the 911. If one were to strip down everything that bears a Porsche logo, that exemplifies and drives the company, to reveal the core of the brand, it would look like a 911. With its unmistakable flyline—the typical roof line—the 911’s style-defining basic form retains its freshness and trailblazing spirit even today. It’s all about that sporty note The next 911, generation 992, will carry on that proud tradition. “We know where we’re from and where we want to go,” says Achleitner. “The decisive factor is that the 911 generates a driving feeling that no other car can impart.” That’s not meant in an arrogant way, it’s really just the nature of things: the specific seat position, the flat-six engine in the rear, its inimitable sound, the astonishing amount of space, the perfect feedback from the brakes, steering, and pedal system together with the striking suspension, the powerfully dynamic but always easily controllable burst of power, and the one-of-a-kind design that ties it all together, making this car the epitome of what it has meant to be a sports car—for fifty-five years. Achleitner: “We know where we’re from and where we want to go.” The riveting question is how the 911 needs to develop in the future to continue to define the brand as the gravitational core of Porsche. Automotive industry megatrends—including digitalization, electrification, and connectivity—will play a role, as well as the question of how these trends should be evaluated. “With each innovation, the decisive factor for me is whether it suits the character of the 911,” explains Achleitner. “We don’t necessarily have to be the first in this regard with the 911. What’s crucial, rather, is that every innovation be offered in a typical Porsche manifestation.” Here, it’s the designers, above all, who are called on to work their magic, according to the 911 chief. The 996, for example, was the first to feature a navigation system. When Achleitner looks at this model today, he still finds it beautiful and elegant, although he has to admit that some elements strike him as a bit outdated now. It pains him, “because the car suffers for it.” It’s therefore important, he feels, to design digital interfaces between people and machines that are as timeless as possible. “Anything but contrived,” is Achleitner’s creed. He’s convinced: “Even where the public might be expecting a bigger ‘wow factor,’ in the long run a certain aesthetic reserve pays dividends.” The joy of driving always has to be in the foreground But the visual packaging of new technologies is just one aspect. The other aspects involve the capabilities that they enable. “Even when it comes to the individual assistance systems, they have to fit with the 911,” underscores Achleitner. After all, no one buys a sports car because it offers adaptive cruise control or a lane-keeping assist function. “Those are convenient and useful things. But the customer has to make the choice to use them and, above all, be able to switch them off when they’re not desired.” One thing is especially important to him: the joy of driving always has to be in the foreground. “That’s why a 911 will always have a steering wheel.” And if autonomously driving cars break through more quickly than expected? “Then the 911 will be one of the last cars to drive autonomously.” “The decisive factor is that the 911 generates a driving feeling that no other car can impart.” In all discussions of autonomous driving, Achleitner hews to his line: Porsche and the 911 are a bastion of stability amid the hype, which heretofore has primarily consisted of mere announcements and statements. The 911 will not change radically—and yet it does evolve. It was 1997 when the era of air-cooled engines came to an end and the age of water-cooled flat-six engines began. It was 2015 when the last naturally aspirated engine in the rear of the Carrera was completely replaced by a turbo engine. “Some fans rushed the barricades; it was all gloom and doom for many,” recalls Achleitner. “And then the same thing happened as always: nothing.” The new models have always received even more rave reviews than their predecessors. “That encourages us to think about fundamental innovations in the future as well.” Electric drive technology? Why not? Electric drive technology is a good example. “Two years ago I’d have said no way. Today I wouldn’t categorically rule it out,” concedes the head of the model line. Just to preclude any misunderstandings: the Porsche 911, Type 992 is not an electric sports car. But it could be an option somewhere down the line. Achleitner describes his ongoing change of heart: “I drove the prototype of our coming electric sports car, the Mission E, and it was a very compelling experience. And the performance of the Porsche LMP race cars with hybrid drive systems is quite simply sensational.” Achleitner is certain that no car with a combustion engine alone could beat them around the corner. Although he admittedly clings to the flat-six engine, he can, nowadays, imagine an electric motor in the 911. So there will be a next step in terms of drive technology—if it fits Porsche and the specific character of the 911. The secret of the Porsche 911 could perhaps be described as follows: it’s the sportiest and most dynamic car in the company’s line-up, but also its bastion of stability. A point of orientation for which Achleitner has found a very simple development principle—which may have something to do with that short talk back in Berlin in 1990. In contrast to his counterpart that day, he does have an idea: “The new 911, too, will be the best 911 of all time.”

    The new W213 generation E63 is a hell of a sedan, don't get BenzBoost wrong. The twin scroll M177 V8 offering over 600 horsepower out of the box makes for a potent powerplant. However, wasn't Audi already doing this? The new E63 is the acceleration champ off the showroom floor (until the F90 M5 is tested): However, notice the Audi RS7 Performance is right there with it. The Performance model is just the same RS7 that has existed since the previous generation E63 hit the streets with a tune and a warranty from Audi. Speaking of tunes, the RS7 is ahead of the W213 E63 AMG tune only. Tune only examples have run 10.4 @ 132 in the 1/4 mile. The new E63 has a best run of 10.6 @ 130 with a tune. If you look at it as Mercedes-AMG coming to market later with a similar top mount twin scroll 4.0 liter twin turbo V8 and trailing an Audi that was already on the market since the 2013 model year what exactly is the E63 bringing to the table that is new? Well, they threw in a drift mode so that is cool and the styling inside and out is spectacular. The handling of the E63 is indeed better at least as far as grip is concerned as is the braking: In pure performance terms though? The E63 is just as heavy as the RS7, has very similar engine architecture, and is not as strong with a tune as an Audi that has been on the market since the W212 generation E63. The new E63 is a great car it just is a shame Mercedes-AMG is not differentiating it in a greater way from a five year old rival that offers more bang for the buck. This new generation of sport sedans is getting boring.
