The new-generation M car—which gets its own chassis code for the first time, F82—sheds its predecessor’s naturally aspirated 4.0-liter V-8 in favor of a quintessentially BMW straight-six. BMW has affixed the “TwinPower” moniker to the all-new, M-developed engine; the badging is applied to BMW’s gas and diesel turbocharged engines, and can refer to single, twin, or triple turbos, single or multiple dual-scroll turbos, or a turbo with variable inlet geometry. The M4 is fitted with a pair of Mitsubishi-sourced turbochargers.
The M4’s 3.0-liter unit, code-named S55, can rev up to 7600 rpm—a remarkable achievement for a turbocharged mill. The twin-turbo six-cylinder is rated at 425 horsepower from 5500 to 7300 rpm, while torque tops out at 406 lb-ft from 1800 rpm. Those are increases of 11 horses and 111 lb-ft of twist versus the V-8–powered M3. The standard transmission is a six-speed manual, which automatically revs on downshifts. The optional transmission is a seven-speed dual-clutch automatic, which delivers quicker shifts in exchange for additional weight.
Top speed is governed at 155 mph, but we believe that there will be an option to raise that limiter to 174 mph. Despite the impressive gains in output and claimed performance, the Bavarian automaker says that the M4 will be 25 percent more efficient than the model it replaces.
The loss of two cylinders certainly aids the quest for improved efficiency, but a strict diet played a role, too. BMW says that it cut 175 pounds from the E92-generation M car—the F82 is said to weigh exactly as much as an E46 M3.
