BMW claims its new 2014 F80 M3 and F82 M4 produce a robust 425 horsepower and 406 lb-ft of torque at the crank. It turns out the Germans are being a bit modest with those figures, a point which was proven when European Auto Source hooked a stock 2014 M3 up to a dyno at their shop.
According to the video below, the M3 actually produced 424 horsepower and 426 lb-ft of torque at the wheels. When you factor in the 15 percent drivetrain loss, the M3’s twin-turbocharged 3.0-liter inline six is actually making around 470-480 horsepower. So now the question remains, does this spell trouble for the impending Cadillac ATS-V?
We haven’t heard a peep about the upcoming compact ‘V’ model from Cadillac, but the automaker is hard at work on the car, testing it in the open for all to see at the Nurburgring. Rumor has it that it may use a variation of the 3.6-liter twin turbocharged LF3 V6 found under the hood of the CTS and XTS Vsport, which produces 420 horsepower in the CTS. If the ATS-V does use that engine, it won’t be enough to take a proper fight to the M3 without a power increase to at least 450 horsepower.
It seems likely that the engineers working on the ATS-V are keeping a close eye on the M3 and M4, but they should be warned, BMW might be slightly downplaying its capabilities. The upcoming CTS-V has been spied testing alongside the current-gen F10 M5, so maybe they’ll manage to get their hands on an M3 or M4 before development work on the ATS-V is complete.
