Update Now BMW has finally pulled back the curtain a bit farther on the M3 sedan and M4 coupe, revealing a tantalizing amount of technical detail during a "second look/first ride" event held near the vehicle's birthplace outside Munich. We'll spare the suspense and let you know that corralled within the aluminum hood and front fenders lies an all-new, 3027cc twin-turbo inline-six that BMW promises will provide the instantaneous throttle response, linear power delivery, and stirring engine note of a high-revving naturally aspirated engine, and the stout, broad-as-Ayers-Rock torque curve of a turbo. And yes, it's an all-new engine, with an 89.6mm bore and 80.0mm stroke (the 335i measures 84.0 x 89.6, for 2979cc) that we're told will produce somewhere in the neighborhood of 430 hp and 370 lb-ft of torque. That's 25 percent more torque with a claimed 25 percent less fuel consumption (see our Engine Deep Dive below for more). A choice of six-speed manual (with automatic rev-matching in Sport, but not Sport Plus mode) or seven-speed M Double Clutch Transmission (using the M5/M6's taller gearing) will route all that furious twist to the rear wheels.
