BMW’s new high performance models

FOR the first time, BMW M is expanding its high-performance line-up to include the X3 M and X4 M Competition models, and both will herald the arrival of a newly developed six-cylinder engine where 3D printing has been utilised in its production.

The X3 M Competition, a midsize SUV, and the X4 M Competition, a Sports Activity Coupe, will be powered by the high-revving unit that features track-proven cooling and oil supply systems as well as the latest M TwinPower Turbo technology update.

Generating 510hp, the 3.0-litre in-line petrol engine has a peak torque of 600Nm while a dual-branch exhaust system helps to deliver an intoxicating soundtrack.

The ongoing development of M TwinPower Turbo technology, coupled with the inclusion of two particulate filters and four catalytic converters, ensures the high-performance, lightweight unit can claim remarkable efficiency and exceptionally low emissions for an engine of this size.

In the BMW X3 M Competition combined fuel consumption is 26.9mpg* with CO2 emissions of 239g/km while the X4 M Competition returns 26.7 mpg and CO2 emissions also at 239g/km.

The use of cutting-edge technology is at the very heart of the engine.

Indeed, the cylinder head has a core manufactured using 3D printing. This additional manufacturing process enables geometric forms to be created that are beyond the capability of conventional metal casting techniques.

3D printing technology has cut the weight of the new engine’s cylinder head core and allowed its coolant ducts to be routed in a way that optimises temperature management.

The six-cylinder in-line engine serves up its peak torque between 2,600 and 5,950 rpm. It generates maximum output at 6,250 rpm and sustains its power delivery until the 7,300 rpm ‘red line’.

The BMW X3 M and BMW X4 M Competition accelerate from zero to 62mph in 4.1 seconds, while top speed is electronically governed at 155mph. If the optional M Driver’s Package is specified this rises to 174mph and the customer receives the chance to participate in an M Intensive throughout the world to hone their driving skills.

Meanwhile, a new plug-in hybrid lineup for BMW’s flagship 7-Series has been revealed, with performance, technology and luxury coupled to short-distance emissions-free capability.

The plug-in hybrids combine the sportiness, comfort and feel-good ambience of BMW’s flagship luxury models with increased efficiency. There is a choice of two model variants: the BMW 745e and the BMW 745Le xDrive, the latter of which gets intelligent all-wheel drive.
