The next generation BMW M5 has been caught testing again and this time it revealed its engine. And while we do not have a clear shot, we presume we are indeed talking about the same engine as found in the X6 M: a twin-turbocharged 4.4-liter V8 engine that will deliver around 555 hp and 680 Nm torque, making the new M5 far better than the model it replaces. It will sprint from 0 to 62mph in just 4.4 seconds and will hit a limited top speed of 155mph or 188 mph with the optional M Drivers Package.
Of course, the new M5 BMW will focus on reducing the car’s weight, so expect an aluminum chassis and intense use of carbon fiber parts. The new M5 also gets an electronically-controlled limited slip differential and Dynamic Performance Control, which sends extra power to the outer wheel when cornering to reduce understeer.
The official debut will be made at the Paris Motor Show later this year with sales set to begin sometime in 2011.
