From now on, every M motor will simply be based on an engine already in production. That means whatever cylinder count and block is already available in a chassis is all you will ever get standard model or M model be damned. The M purist has been moaning about this for years that BMW M motors will essentially just become their standard counterparts with some different software but the head of BMW M (Friedrich Nitschke) finally officially confirmed the days of the unique M motor built from the ground up by the M division are quite simply, over:
So the engines will be closer to the standard engines. We already see that in the N63/S63 motors a good example being the X5 50i and X5 M. For BMW this means huge cost savings and that certain internal parts do not even need to be changed. For example, the same pistons can be used for both an M and non-M motor now:
This is obviously a cost saving measure. BMW can share blocks, internals, and change software yet charge a huge premium. They can even offer performance software as a quick cash grab without having to change any hardware. The cost for the consumer doesn't become more affordable (M models are actually getting more expensive) but the profit margin for BMW increases. You get less, both for your dollar and in hardware choices, yet they make more. Hey, BimmerBoost tried to warn you.
So don't expect to see anything made by the M-Division like an S54 ever again. Or an S38. Or an S65. Or an S85. Or an S14. Those are not motors you can just slap different software on and simply call M engines. The M division is officially dead kids along with BMW's pride, get it through your heads.
This information all comes from an intereview by Car and Driver with head of M Friedrich Nitschke. It's quite amusing to see him believe the garbage he is spewing to Car and Driver. Some great lines to read:
The M5 and M6 are on a level with the competition weight wise? All wheel drive is too heavy? The competition has all wheel drive and weighs the same as BMW with rear wheel drive if not slightly less. A recent comparison of convertible GT's had the F12 BMW M6 come in last place because of poor driving dynamics and the heaviest curb weight by far with the car not offering much more than straightline acceleration.
What the hell is Nitschke talking about?
Game over kids, BMW M has buried their heads so far in the sand they can't smell their own BS.
