The new 3.0L turbocharged inline six for the M240i is the same B58 as was just released in the updated-for-2016 340i. The new engine gets a 15 hp boost (to 335) and torque jumps to 369 lb-ft. That's surprisingly close to the M2, which makes the same torque and just 30 hp more. BMW claims that the 0-100 km/h time drops by about 0.2 seconds with the upgrade. While the upgraded handling and features of the M2 are certainly not insignificant, the M235i comes very close to matching it already, so the upgrade will bring things very close.
