    • Fat and Fast - The 2020 G20 BMW M340i RWD runs a 12.3@115 1/4 mile with a 3827 pound curb weight

      A 3800+ pound rear wheel drive BMW 3-Series. That is what you get with the 2020 G20 BMW 340i and this is not even the xDrive all wheel drive version. Car and Driver weighed their test car in at a recorded curb weight of 3827 pounds.


      What does the all wheel drive xDrive version weigh then? Well, we need to see an independent weight test but BMWUSA claims a 3968 pound curb weight. That means we are potentially looking at a 4000+ pound G80 M3 or BMW will have to do some real work to keep it in the 39XX pound range.

      Despite weight ballooning to what was once 5-Series territory the B58 powered M340i performs and performs well.

      0-60 in 3.8 seconds. A 1/4 mile sprint of 12.3 seconds at 115 miles per hour. The M340i is running E92 M3 times with plenty of performance left under the hood for the aftermarket to unlock.

      The steering is said to be a bit muted which is very much against the traditional 3-Series recipe.

While the M340i features a launch-control system for hasty getaways, we found that taking matters into our own hands and managing the turbo-six's silken thrust ourselves was the quickest way off the line. Ultimately, the M340i ripped off a 3.8-second zero-to-60-mph sprint and tore through the quarter-mile in 12.3 seconds at 115 mph. If you are wondering, those times are on pace with the last-generation M3.

      We've griped about the 3-series's steering since the previous F30 generation launched in 2012. Although the G20 represents an improvement in that area versus its predecessor, the dull off-center movement and its numb connection to the road is not the steering feel that the M340i truly deserves. The chassis, however, is well-balanced and the optional 19-inch Michelin Pilot Sport 4S summer tires are hooked up, clinging to the skidpad with a stout 0.96 g of grip and returning a 155-foot stop from 70 mph.
      The G20 340i simply is more muscle than finesse.


      Unfortunately, it is only available as an 8-speed automatic in the USA which is very much against the Ultimate Driving Machine philosophy. Does it matter though? People want power and BMW is delivering easily exploitable power.

        Woah, now I really wonder how much our G20 M340i is on the scales. That's crazy.

        Have any customer cars matched this time or are we looking at a magazine tune?

        It's a magazine time.

        It all depends on the prep or where the car was tested.

        Car mags were popular pre-internet it was the only way to read about new cars and check out specs. You were tricked into thinking the car mags were giving a fair and impartial review never knowing those opinions were bought and paid for by the highest paying manufacturer. Now days you can see real people posting real times online, real people with real reviews online. Online communities sharing information, its great. It’s real. Car mags are done.

        Interesting note on the steering. The only other comment I've read was about someone getting a loaner while their F30 was at the dealer, and how the G20 steering and suspension were exponentially better.

        That is only in the Supra Mk. V and is denoted as the B58B30C.

        The G20 M340i USA has the B58B30O1 sometimes referred to as the "B58D," which makes no sense to me. But neither does the C designation as it does not conform to BMW engine description naming system. "C" is undefined.

        Suspension with the adjustable dampers covers a wider range and is truly comfortable and silent in Comfort Mode. Sport + is still pretty much for perfect tracks or billiard tables.

        The thing that really impressed me was the chassis torsional rigidity. Definitely a reason is is so quiet in Comfort Mode.

        While it is still electric power steering rack, I would say the car on the whole has a whole lot of finesse to it. I would peg it as about 90% of the performance of the M5C I drove that day also, for half the price and a lot fewer trips to the pump. At lock you up speeds, the M5C is just ridiculous, though.

        Do we consider this a mag time or moreso indy as it is a long term test, or seems that way due to 1200 miles of break-in they performed.

        Mag time regardless and a quick one for sure considering the hp and torque at 3800 pounds.
