BMW M – Now in 3D

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 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.

BMW SUVs going from zero to 62mph in 4.1 seconds and with a peak torque of 600Nm – Mmmm what a great use for 3D printers
