New Twin Turbo Engines Power 2017 BMW 2-Series

BMW supplies the 2-Series with a pair of more powerful, yet efficient engines.

For 2017, BMW is providing its entry-level 2-series line of coupes and convertibles with more power thanks to a pair of new twin turbo engines. As a result, new sub-models will debut with the M240i replacing the current M235i, while a new 230i line steps in to succeed the 228i.

More Power, Improved Speed

The 2017 BMW 230i Coupe and BMW 230i Convertible models are powered by the latest generation four-cylinder, 2.0-liter engine making 248 horsepower and 258 foot-pounds of torque.

On the M front, the BMW M240i Coupe and BMW M240i Convertible gain a new six-cylinder, 3.0-liter engine making 335 horsepower and 369 foot-pounds of torque, up from the current 320 horsepower and 330 foot-pounds of torque.

BMW claims the M line’s 0-to-60 mph performance times have narrowed to 4.2 seconds for the all-wheel drive model, effectively shaving 0.2 seconds off the current time.

The six-cylinder produces more power over a wide rev band. Maximum horsepower is reached at 5,500 rpm, while peak torque is maintained from 1,520 to 4,500 rpm. Both models offer standard rear-wheel drive with xDrive all-wheel drive available.

Rear-wheel drive buyers can choose between an 8-speed manually shiftable automatic transmission or a 6-speed manual with rev matching. All xDrive models are outfitted with the automatic.

Inline-6 Engine Changes

BMW’s inline-6 is outfitted with a new aluminum crankcase and cylinder head along with new acoustic shielding. The two turbos replace the previous single turbo and are integrated into the steel exhaust manifold and electric wastegate control.

The new arrangement virtually eliminates turbo lag; it features a dense design and includes an indirect intercooler incorporated within the intake manifold.

Other changes include the latest variable valve control system, enhanced to improve load control, engine responsiveness, and efficiency. Double-VANOS variable camshaft timing is also present and located on both the intake and exhaust sides.

An electric coolant pump for the intercooler operates only as needed, a map-controlled oil pump, electric power steering, and auto start stop function are present. This model also benefits from brake energy regeneration in an effort to improve overall efficiency.

BMW M Series

Additional changes to the M Series line include lowering the sport suspension by 10 millimeters or 0.393 inches. Further, all-new, 18-inch M light-alloy wheels come with Michelin Pilot Super Sport tires, an M Sport braking system is outfitted with fixed multi piston calipers, the variable sports steering has a servotronic function, and a model-specific M aerodynamic package and exterior mirror caps is now offered in Ferric Grey metallic.

Manual gearbox fans will find a 6-speed with rev matching. Specifically, BMW says on downshifts “…the transmission management increases shift comfort by initiating a quick and precise rev matching function; as the driver shifts into a lower gear, this increases the engine’s revs to the ideal level for the target gear.”

As for prices and the new fuel economy numbers, that information will be released closer to the 2017 2-Series’ release date later this year.
