The engine downsizing trend evident throughout the new, sixth-generation BMW 3-series line-up is also set to be a feature of the successor to today’s BMW M3.
This new performance flagship will reach the UK in coupé form during the first quarter of 2014. When it does, it will forgo the existing M3’s naturally aspirated 4.0-litre V8 in favour of a new twin-turbocharged 3.0-litre, six-cylinder engine that is currently under development at BMW’s M division, on the outskirts of Munich.
The new unit is also scheduled to be used in a successor to the BMW 1-series M Coupé, but in a lower state of tune. The engine has been described to Autocar as being heavily differentiated from the company’s existing twin-turbocharged ‘N54’ and twin-scroll turbocharged ‘N55’ 3.0-litre engines.
Features that have been identified as being unique to the new M Power engine include the management system, induction system, cylinder head, pistons and connecting rods.
Although it is still early days, BMW M insiders suggest that the new six-cylinder engine will produce more power than the existing 414bhp V8, despite its smaller capacity.
