BMW is launching its 2017 X4 M40i model with the high performance M2 engine.
The M2 engine is expected to deliver enhanced power, torque and a highly improved performance for the new BMW X4 M40i model.
The M2-powered 2017 BMW X4 M40i model is estimated to have an output of 370 horsepower driven by the enhanced efficiency of the M2 engine whose parts have been borrowed both from the M4 and M3 engines. The peak power delivery presently for the M40i model is 360 hp which is achieved between 5800 and 6000 RPM. The new M2 engine is expected to enhance this not-so-great performance much further.
The M Performance torque is estimated to be 465 Nm, a huge increase from the 400 Nm peak torque of the existing inventory of xDrive35i models. While the M2 engine’s N55B3OTO unit is estimated to have this same peak torque, it could reach a peak of 500 Nm by leveraging on the ‘overboost’ function for short performance bursts.
Using the above data, the fastest performance figures (time to reach from 0-62 mph) for the M2-powered BMW X4 M40i would be 4.3-4.4 seconds. This is expected to be achieved by taking advantage of the 7-speed manual Dual Clutch Transmission system. For the sake of comparison, the M4-powered 7-speed DCT gearbox fitted vehicles achieve the 0-62 mph in 4.1 seconds while the 8-speed auto transmission system fitted M235i xDrive vehicles do it in 4.6 seconds.
The difference of 0.2-0.3 seconds between the M4 and M2 engines is attributable to the manual transmission system of the BMW X4 M40i.
The pricing of the M2-powered M40i model is estimated to be between the M4 (starting at $65,400) and the M235i (starting at $46,100) models. Hence it is estimated that the starting price of the new M40i models will be approximately $50,000.
Again, for the sake of comparison, the starting price of the Cayman CTS which is comparable (with regards to performance) to this new BMW model is $75,200. Another comparative model (again with regards to performance); the 911 Carrera is even pricier, starting at $89,400.
