The 1M gets away with it because its a limited run, cheap entry model, so I can see the economics behind it. The M3 and M5 are the flagship M models.
Fair point actually!
The V10 in the M5 was used for the M5 Sedan & Touring, M6 Coupe & Convertible......and that's it.
M is utilizing the V8TT in the X5M & X6M, M5 Sedan, possibly M5 Touring, M6 Coupe, M6 Convertible, and M6 GranCoupe. Nearly twice as many models, so you'd think BMW would give M the budget to develop a unique powerplant.
I imagine when it comes to forced-induction engines, the key is (as the name suggests) the forced-induction portion of the powerplant, and focusing on that particular aspect is where most improvements can be made.
We see with the N54 in the 1M, that M mostly tweaked the software...I'm excited to see what all that heavy-duty work on the V8TT will deliver for the M5!
The E92 M3 and E60 M5 had unique engines, so I see the F10 M5 as a step backwards!
