That sound. That glorious noise of the F10 V8 ‘s engine has piqued our interest. Where the E39 sounded nothing short of perfect at full power, the E60 ‘s V10 never quite reached goose bump territory. And judging from previous prototypes we had some serious reservations about this new M5 ‘s twin turbo charged V8. Especially considering it ‘s based on the 5.5 4.4L M V8 found in the X5/X6 twins. An engine not known for it ‘s robust soundtrack.

But this test mule somehow seems to come alive under full power like no other prototype before it. Add to it lightening fast DCT shifts and a nice growl on lift off and you have a great sounding package.
