    AUTOCAR: Next M3 will get new twin-turbo six-cylinder, not tri-turbo

    Click here to enlarge


    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.

    At the recent launch of the hardcore M3 CRT saloon, BMW M development boss Albert Biermann hinted at an output in the region of 450bhp from the new unit.

    This move is aimed at providing the next M3 with the performance to match the Audi RS5 and recently facelifted Mercedes-Benz C63 AMG.
    But whereas the existing M3 makes do with 295lb ft of torque, the 2014 model is set to pack as much as 400lb ft for further performance gains.

    with 450hp this car should be much lighter than E9X M3 to keep up with rivals.

    BTW didn't Autocar bring the triple turbo engine in the first hand?

    I guess the tri-turbo rumor is out the window. If the M division actually designs the engine and it's not just a regular tuned BMW engine, then there's some hope for the enthusiasts.

    M88 --> twin cammed, bored M49
    S38 --> same as above but with higher CR
    S14 --> twin cammed, bored and stroked M05 with individual throttle bodies
    S50 --> bored and stroked M50B25 with individual throttle bodies and new manifold ( dual VANOS in S50B32 ) and higher CR
    S52 --> renamed M50 (?)
    S62 --> Bored and stroked M62 with Double Vanos and some minor ( but effective ) changes and higher CR
    S54 --> tweaked S50B32 from every prespective and higher CR
    S65 --> 8-cylinder version of S85 ( stroked in S65B44 )
    S63 --> lowered CR, higher boosted N63

    all the engines above are based on regular BMW engines. in fact except S85, all the engines in M cars have been a tuned version of the normal units. the changes over the base models aren't that eye catching, but the result have been absolute superb.

    now we are here, a N54 based engine is going to be in an M3. with these mods
    include the management system, induction system, cylinder head, pistons and connecting rods
    I think N54 deserves to be the heart of an M car whereas some may disagree.

    totally agree...

    it'll be very nice to bore out the N54 with some larger forged pistons and lighter rods and 1 point (9.0) lower compression...if I don't do this by next summer I'm holding out for the M3 Click here to enlarge

    Well said. Shouldn't cost so much to make extra power vs the current M3, and if this thing has a badass head and an upgraded fuel system it will really help development of the N54 upgrades and maybe give us some good bolt-on goodies.....

    The third turbo would be nice. Let's hope it will have it. However, it they would just end tweaking the head, intake and turbos of N54/55, 450bhp wouldn't be too hard that way either.
