We might think that but the folks in munich thinks otherwise

I believe the E34 M5 got an engine upgrade during it's life time - so it does have past precedence.

Well, yes. But I'm not overly happy with needless power updates.

.......I propose that the next M3 should have 782bhp.

I find it hard to believe that they would try to match RS6's power figures. They already said M will concetrate on weight reduction instead of power increase in the future. So maybe a smaller update with more extensive use of light-weight materials is possible. Replacing the SMG III with the M DCT would make it even more attractive for many potential customers.

M5 CS perhaps.

That's exactly the idea I was going to suggest. Instead of actually upgrading the M5, they might just offer an extra package like they did with the E46 M3.

I agree with many of you that the M5 doesn't need the extra power, it's got more than enough.

One question though, if they decide to offer more power, will the engine displacement remain the same, or will it become a 5.5L engine producing ~550-580hp?

ell i'm not thrilled about the upgrades also only AMG cars that makes me happy ith more power ,and for the next M3 well lets say it's too soon to predict....

Sounds nice, but we'll see how much of that is true of course.

Amazing how the guy can 'hear' so much, even knowing what gearbox it has..

Think they should make a M5 CSL instead, a bit more carbon fibre and more power will amplify the effect, to keep current M5 owners happy.

Obvious follow-on question. If the M5 does indeed get a power and performance upgrade (performance upgrade as in improved suspension and so on)... then what of the M6? Surely the top of the M-range M6 cannot be out-done by its sibling sedan brother - the M5.
