    • MotorTrend compares the 2015 F82 M4 to the Lexus RC-F and the RC-F gets spanked

      This is really no surprise. We could have told you which car won before they were even compared. That said, it is nice to have support for that assertion and it is provided by MotorTrend. The Lexus RC-F feels like it is fighting last generation's battle and simply is not the performance car the F82 M4 is.


      If it sounds like we are being harsh keep in mind the RC-F has the same old 5.0 liter V8 (with some tweaks of course) that we have seen since the days of the IS-F and back then it was not exactly impressive. The redline is raised to 7300 rpm from 6800 rpm and the motor gets a compression ration bump to 12.3:1 from 11.8:1. This results in 467 horsepower and 389 lb-ft of torque at the crank.

      This motor is asked to move 4045 pounds Lexus coupe. Why is it so heavy? Who knows but the M4 suddenly looks like a lightweight with its 3604 lb curb weight. The weight loss of the M models has been overstated but considering the bloated Lexus we will not be so hard on the BMW that manages to continue being the lightest car in its class.

      The weight distribution figures are not pretty for either car. The M4 amanges 52/48 front to back while the RC-F is an even worse 54/46. BMW is shying away from 50/50 and should not be let off the hook for it but they still do not go as nose heavy even with the turbo motors as many of their competitors.

      Although the RC-F is more powerful on paper we seriously doubt it in practice with how the M4 S55 3.0 liter turbo inline-6 is underrated. Put both of these cars on a dyno and the M4 smoking the RC-F will become more apparent than just by looking at the crank paper figures along with the curb weight. The DCT transmission of course is a factor and helps compared to the Lexus 8-speed automatic.

      The M4 runs a 12.2 @ 117.8 1/4 mile to the RC-F 12.7 @ 112.2. The longer the race goes the worse it gets for the Lexus. As stated, the RC-F feels like it is a generation too late as it would struggle with the previous generation E92 M3 let alone the much more powerful F82 M4.

      Ok what about track performance? Well, the RC-F loses there too with the M4 beating its laptime. It is fairly close with the M4 1:23.73 laptime to the RC-F 1:24.05. The Streets of Willow is not exactly a big power track as it is fairly tight and technical which will make the cars appear closer than they really are. Put the M4 on a track where it can stretch its legs a bit and the gap will widen.

      Really, this isn't a contest. MotorTrend prefers basically everything about the M4 and they should. It's more fun to drive, it's faster, brakes better, handles better, offers greater efficiency, is more modable, better balanced, and it is at the top of its game while the RC-F is playing catch up. I guess we can give Lexus a pat on the back and tell them good effort. Maybe they will have a worthy competitor next decade.

        To me that looks like a win for the Lexus. It hanged with M4 on the track, being heavier and most likely with less real power than M4. My guess is that Lexus almost never sees track, bout doubt M3 drivers track it often either. I would call it "spanked" if M4 had at least a second or two on Lexus, but it didn't. I find it surprising that Lexus was that good with "old" tech.

        As for the looks, just saw M4 recently and I couldn't find any real differences between M4 and 4 series (they look pretty much the same).

        In the long term, I'm pretty sure Lexus is more reliable compared with yet to be proven M4. If 335i is of any indication, we can start thinking of HPFP, LPFP, injectors, coils, turbos, water pumps, and whatever else (and that is for DD).

        I think M4 barely made it against Lexus, which in turn makes me think that updated Caddy (ATS-V?) will take it.

        You should look again then. The BMW beats it in absolutely everything.

        It got spanked, hard. As mentioned the only reason it is even close regarding the laptime is due to it being the Streets of Willow. Considering how much better the BMW brakes it is odd the only time the Lexus can make up time is during braking.

        I hate to say it but it's time for someone else to drive these cars than Randy Pobst.

        Regardless, the BMW has more power, is lighter, better balanced, brakes better, has the better rubber, and better suspension and you think its close? Come on.

        That's on you. I can easily tell the difference from quite a distance.

        The 335 isn't an M car.

        The M4 crushed it. A close laptime on a tight track (what was the average laptime? How many laps?) isn't barely making it. The M4 is superior in literally EVERY performance category by a wide margin.

        The RC-F is an embarrassment.

        I would bro. NA V8, barely slower on the track, and when the M4 has had it's 7 set of injectors, been walnut blasted 12 times and fourth HPFP the Lexus will still be reliable.

        It's a crappy NA V8 that you can barely mod (where are all the powerful IS-F's?), way heavier, has an automatic, and looks like garbage. The rear end looks like something they had a 12 year old design.

        I agree on the direct injection being a pain in the ass but if that's what you want the E92 M3 is better than this thing.

        The RC-F sucks.

        I agree on the E92 being better indeed. The RC-F isn't gorgeous but neither is the M4. It's bland.
        There is an 800hp ISF but I agree it's a very under modded motor.

        I agree on that but the M4 doesn't look riced out:

        The exhaust is so utterly stupid looking I don't know what to say:

        They aren't running with any M3's. If you want a 4000 pound car with a V8 might as well get a Hellcat.

        Sticky, I agree with most points. Lexus is ok by design (what do you expect from Toyota designers?), but M4 does look a little meh for being an M car. If your intention is to mod and track M4/3 is the way to go, but if you don't plan going to the track and just do some occasional reliable spirited driving then Lexus is not a bad choice. Lexus statistically is way more reliable than BMW and since this is not a brand new engine or anything I expect it to outlast BMW. Modding is great, but sometimes you just want to get reliable fun first, and this is yet to be seen from M4/3. E90/92 had NA engine, and way more reliable than 335i, but now essentially M4/3 will have a similar setup as 335i with upgraded components (and new engine?), but I doubt issues with direct injection are resolved (there is a new index on injectors every year it seems), as well as HPFP etc.

        It's a tweaked motor. The S55 is a tweaked N55 with a new block.

        Generally Lexus is more reliable but it's easy to be reliable when your cars are boring and not pushed hard in performance.

        Sure these are all potential issues. That said, the RC-F is more a match for the E92 M3 than the F80 M3.

        There are many better options than the Lexus. RS5, C63, upcoming XE with the V8. I'd even rather have a Mustang, Hellcat, or Camaro.

        The RC-F is just too little, too late. I suppose it will appeal to some but younger enthusiasts are aware of better options.

        RC-F seems more like a GT car. I'd rather have an RS5, it weighs less and you get awd, plus a dual clutch.

        M4 did seem to dominate this comparo. It won every measured test.

        Sticky, I agree that there are better options, but it's surprising that Lexus was even in the game against M4. Few years back it would have been a joke, now either M became soft or Lexus and others catching up.

        How is it in the game? The RC-F isn't barely competition for the E92 M3.

        You're putting this all on a single laptime on a tight course and ignoring every single other performance statistic that is laughably one-sided?

        So if I took these cars to Nurburgring and the M4 out-lapped it by 20 seconds then your perspective would change?

        It seriously isn't even close between the two. The RC-F IS a joke.

        Watch the hot lap side-by-side part. I know its Pobst at the wheel but jeeze he does not know hot to control the m4. He loses the rear end far more often than the rcf and was babying it out of corners.

        Sticky, what % of owners track their cars? My point is that most owners don't race from point A to point B in real life and could care less if it is a little slower or maybe even a lot slower on the track. I was trying to say that if you do not mod the cars and leave them stock, for a daily use car performance is almost identical as you will not be pushing those boundaries 99% of the time. It will always be a choice of which one you like better and how it feels. There will always be a faster car out there...

        You're incorrect in the point you are making. You are right, most people do not care about track performance.

        Therefore, in the real world the performance difference is all that much greater. The M4 is way faster than the RC-F. It also provides more torque down low, fact. So, every day it's simply providing much more power and torque without having to extract this on the track. You don't need to push the boundaries to feel the benefit at 2500 rpm.

        That said, I prefer an NA motor but the RC-F is trailing its competitors significantly. It is closer to the E92 M3 in performance as stated repeatedly.

        RC-F is a major let down. The hodge podge chassis they grafted together from 3 different cars is embarrassing.

        Back when the IS-F came out, it was a giant leap forward for Lexus. It was actually quite impressive. The RC-F like Chris Harris said "Lexus has probably arrived at a 2014 party in 2008 clothes".

        (ATS-V?) will take it.
        I see people complain about the 335 hpfp all the time. Its not like BMW made the hpfp. BMW didn't make the hpfp, i believe it was Bosch, so the failure is on Bosch not BMW. Toyota is experiencing problems with hpfp's as well, currently on the scion frs. You complain about injecotrs, well the lexus has 16 incejtors, that might get expensive if they start to fail. I work on Toyota's, Lexus's and Scion's daily and there biggest failure is water pumps. All you're doing is making excuses why BMW is so "bad", every car out there has common problems. If you look at the statistics above the M4 Beats the RC-F its that plain and simple. And anyone saying they would rather a NA is your choice, but almost all car manufacturers are now offering turbo models, due to emissions and power. Smaller engines with turbo's have slowly been replacing larger displacement engines.
