InsideLine dyno-tested the new 2011 BMW 1 Series M Coupe. Here is a video and excerpt from their report:

“Equipped with the company’s N54 twin-turbo 3.0-liter direct injected inline-6, the 1 Series M Coupe is rated by the factory (that is, at the flywheel) at 335 hp at 5,800 rpm and 332 lb-ft from 1,500-4,500 rpm.

Peak torque rises to 370 lb-ft during an overboost period, the command for which is not driver-activated. That little “M” button on the steering wheel sharpens the throttle response, and nothing more.

We’ll assume the overboost function was live because, well, just have a look below at the result from the Dynojet chassis dyno:

Dyno Tested: 2011 BMW 1 Series M Coupe – 331whp/362rwtq 400 hp at crank

Whoa! Now that’s some torque. From 2,500-4,500 rpm, there’s more than 350 lb-ft on tap, and then it rolls off linearly between 5,100 and 6,700 rpm. It’s pretty much done at that point, and the fuel cut arrives at 7,000 rpm. Peak power of 331 hp arrives at 5,150 rpm.

Torque peaks at 362 lb-ft and hits early in the rev range. As explained in a previous post, it’s nigh unto impossible to replicate on a chassis dyno the drawn-with-a-laser-level torque plateaus that manufacturers provide for their turbo cars.

While BMW says it reaches peak torque at 1,500 rpm, you’ll never achieve that result in the real world unless you wood it at 1,000 rpm in 5th or 6th while climbing a hill. No matter, since only a complete toolshed would drive an M car — or any car — that way. Downshifting. Learn it.”

    That translates to over 400HP at the crank!!!! H, you must be getting excited… ;-))

    Thats why you should buy a BMW
    cause you’ll always get more from it than you would imagine! in every way!

    People were speculating that the 1M was more powerful than BMW was letting on, I guess literally the proof is in the pudding.

    IT DID always feel more powerful.   I think  BMW did not wanted to cannibalize M3 sales. Imagine if they say – 1M with 403HP 47,500 or Mr with 414HP for 57,500 ?  10,000usd for little over 10 HP in a slightly smaller chassis and few cool option deleted but essentially a same performance. It would hurt M3 sales. 335HP sounds like a decent  number and still far off of the mighty 414HP

      dont just at the specs sheet and number, then went just straight to the price. The 1M wont hurts the sales of the M3, why? First of all, when you are willing to pay 70k for a car of a size of a corolla, there is only one kind of people who would do so, car guys. car people are able to tell the different between the M3 and the 1M, just look at the campaign BMW did for the 1M, they compared the 1M with the e30 m3, they did so because both car share the nearly same feature, a short wheel base, while the M3 which kept the stretched wheel base since the e36 m3. The m3 and 1m are two total different vehicle.

    when a torque drops off that hard, you can tell the turbo was way undersized.  great PR torque numbers, but leaves a lot on the table had they chosen a correct size turbo.

  • Dont

    IS it really a M car??? Peak power at 5000rpm. Doesn’t sound like sport car.  M cars should be thrilling and high revving:)

  • Nnnn

    Does anybody have any information on how overboost works?   And why is it only a temporary boost?
