The successor to the current BMW M3 will offer a downsized engine, similar to the trend that is seen throughout the new, sixth-generation BMW 3-series lineup. When the new performance flagship arrives in the UK in the first quarter of 2014, it will have the coupe form.
It will replace the current M3’s naturally aspirated 4.0-litre V8 with a new twin-turbocharged 3.0-litre, six-cylinder engine that is being developed at BMW’s M division, outside Munich.
This new unit will be featured in a model that succeeds the BMW 1-series M Coupé but in a lower tuning level. BMW says that this engine is very much different from the existing twin-turbocharged ‘N54’ and twin-scroll turbocharged ‘N55’ 3.0-litre engines.
The features that are distinctive to the new M Power engine include the management system, induction system, cylinder head, pistons and connecting rods. It’s still quite early to say but according to BMW M insiders, the new six-cylinder engine will have more power than the current 414bhp V8, despite having a smaller capacity.
During the recent launch of the M3 CRT saloon, BMW M development boss Albert Biermann implied that when equipped with the new unit, it will deliver about 450bhp.
This would mean that the next M3 will have a performance that could rival the Audi RS5 and the newly facelifted Mercedes-Benz C63 AMG. But while the current M3 offers 295lb ft of torque, the 2014 model could produce up to 400lb ft for additional performance gains.
