BMW makes a M3 and a M5, but it doesn't make an M7. That's where Alpina comes in with the B7->ke536.

The tuner has a long standing close relationship with BMW, so now that there is a new 7-Series out, the new B7 close on its heels. In fact, reports now say that the car will be revealed at the Geneva Motor Show in March. The new Alpina B7 should be powered by a modified version of BMW's 4.4-liter twin-turbocharged V8 engine delivering around 507HP (7 hp more than the current B7).
