BMW has announced the 2017 2-Series will receive a heart transplant across the board. Specifically, both the turbo four-cylinder and six-cylinder models are getting the latest generation versions of themselves, boasting more power and smoother power delivery. Naturally the change is altering the BMW naming scheme, which will now be the 2017 230i and M240i.

The 2017 230i is gaining the newest version of BMW’s well-known 2.0-liter turbo four-cylinder. The updated mill is churning out 248 horsepower and 258 pound-feet of torque, a modest increase from the 228i’s 240 horsepower. This engine will power both the coupe and convertible models.

BMW has also upgraded the M Performance model of the 2-Series. The 2017 M240i will receive the brand’s latest version of it’s 3.0-liter inline-six. It is adding 15 horsepower and 39 pound-feet of torque, carrying ratings of 335 horsepower and 369 pound-feet of torque. The new unit has an aluminum crankcase and cylinder head and the refinement that is a hallmark of BMW 6-cylinder inline engines has been elevated to another level thanks to new acoustic shielding. The twin-scroll turbocharger integrated into the steel exhaust manifold and electric wastegate control is extremely efficient – on account of its compact construction and the presence of an indirect intercooler integrated into the intake manifold.

Of course both power boosts are going to propel the 2-Series from zero to 60 in slightly quicker times. Both engines can be had with a six-speed manual or eight-speed automatic gearbox.
