World Premiere Of BMW X4 M40i


World Premiere Of BMW X4 M40i

More than just a kitted up X4, the X4 M40i has some genuine credentials under the hood. Sitting above the X4 xDrive35i, the X4 M40i is powered by a new inline six cylinders 3.0-litre Twin Power Turbo (single twin scroll turbo) that produces 360 hp from 5,800 rpm to 6,000 rpm. Its table shape-like torque curve, 465 Nm is sustained from 1,350 rpm all the way to 5,250 rpm, delivered to all four wheels.

To cope with the higher level of charging pressure and increase in the volume of fuel injected, the X4 M40i’s engine has an aerodynamically tuned air intake manifold and a new exhaust system that’s optimised both in terms of back pressure and sound character. There’s also a separate oil cooler.

The standard X4’s 8-speed Steptronic automatic transmission has also been retuned with M Performance-specific gear shift programs.

There’s also a launch control program.

The sprint from 0-100 km/h is completed in 4.9 seconds, while the top speed is electronically limited to 250 km/h.

Compared to a standard X4, the X4 M40i’s front camber has been increased, with the adaptive dampers have been retuned to meet M Performance specifications. Stiffer springs and reinforced stabilizers have been fitted on both front and rear axles. The variable sport steering has also been sharpened with an M Performance-specific setup.

BMW have yet to announce any pricing details or when will the car go on sale, but the X4 M40i is expected to make its first public debut at November's Los Angeles Auto Show.
