There's no getting away from it; this is the mightiest BMW of them all. Fabulously fast and furious, decadent to the core, technologically breathtaking, incredibly quick, immaculately built and luxuriously trimmed, this is the ultimate heavyweight coupé. De-restrict its 2005 International Engine of the Year V10 and punch up all 507bhp on the MDrive button and it can charge to 205mph - but not with me at the wheel and certainly never as a passenger.
To take this car anywhere near its considerable limit needs skill - and even more restraint. It's the restraint I'd worry about! This car wants to be driven hard. In normal tune the 90-degree V10, voted International Engine of the Year in 2005, delivers a "mere" 407bhp, but punch the MDrive button on the wheel or the Power switch on the transmission tunnel and at 7750rpm you've got 507bhp. That's more than 101bhp per litre and with it comes titanic torque peaking at 6100rpm, where there's 383lb/ft available.
