BMW 6 Series Gran 650i xDrive

  • $92k
  • 4.4L V8
  • 16 city 24 hwy
Even a base V6-powered 640i Coupe is highly equipped with a leather and wood interior, xenon headlights, navigation system with 10.2-inch display, dynamic cruise control and rearview camera.

The less-powerful S7 uses Audi’s own seven-speed dual-clutch automatic, but that gearbox can’t handle any more twist, so the RS7 is fitted with the ubiquitous ZF-sourced eight-speed torque-converter automatic.
