Yes it's a better platform but it's fundamentally not different which is both a good thing and bad thing depending on ones perspective.

Correct - but they won't do a 8K redline as it will require very different turbo sizing. For BMW its about 100% torque at 2.5K RPM... its 'feels fast' that way.
Notable improvements:
1. Oil sump
2. > 50% fuel pressure (more tuning potential)
3. Combustion shape (piston crown) to accommodate the improved injection
4. Serviceability... that rats next of coolant hoses is now more modular
5. Compressor on the turbo (rest is the same)
6. No MAFs
7. Intake manifold flow seems improved but I need to visually see one
8. Surge compression with the balance duct
9. AWD |
I'd trade all of that stuff for an M5 turbo motor that revved to 8,000rpm or a motor that produced a very different and better exhaust note. McLaren turbo motors rev to 8,500rpm, it's not impossible. BMW has no interest in innovating anymore, when they've got 4 engines powering their entire line up. Luckily they're still making their V12 engine though, which is why I think the M760i is a better buy over an F90 M5 right now. Do a muffler delete on that V12 and you've got a car that gives far more driving pleasure than doing 0-60 in 2.9s. At least to me anyways.
