The Bavarian company is still keeping mum on the performance details, but officials confirmed that the twin-turbocharged V8 lump that replaces the outgoing M5’s 507HP V10 will have more oomph than on the X5 M / X6 M. “Do you really think we would give it less than an X6M?”, BMW officials told Harris. In the X6 M, the twin-turbo V8 kicks out 555HP and 680Nm or 501-lbs/ft of peak torque.
