Here are some exclusive photos of the new engine found in the BMW M3 and BMW M4: Bi-Turbo Inline 6 Cylinder, 430 hp, 369 lb-ft torque.

The high-revving six-cylinder in-line engine with BMW M TwinPower Turbo technology newly developed for the new BMW M3 Sedan and BMW M4 Coupe produces maximum output of approximately 430 hp. Its peak torque soars far beyond 500 Newton meters (369 lb-ft), out stripping the figures recorded by the outgoing BMW M3 by well over 30 per cent.

And yet the engine also achieves a reduction in fuel consumption and emissions of around 25 per cent. The weight of the cars has been reduced to just under 1,500 kilograms, which helps to ensure outstanding driving dynamics and exceptional efficiency.

The BMW M TwinPower Turbo technology comprises two mono-scroll turbochargers, High Precision Direct Injection, VAL
VETRONIC variable valve timing and Double-VANOS seamlessly variable camshaft timing. The variable valve and camshaft timing provide fully variable control of intake valve lift. This allows the engine to deliver its power smoothly and efficiently, resulting in lower fuel consumption and emissions.
At the same time, throttle response is even sharper than before.

The six-cylinder engine features a closed-deck crankcase design, which increases rigidity and allows cylinder pressures to
be increased for maximized power output. And instead of liners, the cylinder bores feature a twin-wire arc-sprayed coating, which results in a significant reduction in engine weight.
A further technical highlight is the forged, torsionally rigid crankshaft which, as well as providing increased torque-carrying capacity, is also lighter in weight. Its reduced rotating masses also improve throttle response and acceleration.

    what’s the engine weight compared to previous ///M V8?

    numbers don’t impress me that much , I hope the M guys know what they’re doing , they will have some really Tough competition , although it could be that the power figures are false (underrated) . the concept design of the car was impressive , will the production version bang the same?…experience says no , but still have to wait and see,

    “The high-revving six-cylinder in-line engine”
    Yes? How much revs exactly?

    Won’t it be Valvetronic instead, unless they stuffed some pets in there?

    And where is the 3rd turbo they promised 2 years ago?

    • viper says:

      the 3rd turbo would increase unimaginable extra costs for bmw , they already have tri turbo diesel , if m3 was a diesel then you would have you’r tri turbo , bmw can’t do a copy and paste every time..
      can’t you see that this time the M used the 3.0 engine (already in the lineup) and probably won’t look like concept so it’s a pretty cheap approach …

        I tend to agree. Audi tends to do the same though. Some Audi engines are “S” on some models and regular “A” in others (S6/A8, S4/A6, SQ5 TDI/A6 TDI). Only RS stays RS from one model to another one.
        MB is more consistent, every AMG engine is specific to AMG models.
