The BMW M6 is all about the engine. The "M," after all, stands for motorsports, while the 560 horsepower twin-turbo V-8 engine stands for pure power and performance. With those kinds of specs, it's little wonder that BMW enthusiasts are glad to have the M6 back after a two-year production hiatus.
Upgrades include an executive package that features adaptive light-emitting diode headlights, soft-close automatic doors, a heated steering wheel, a heads-up display, massage functionality for the front seats, and smartphone app integration.
Buyers can opt for the driver assistance package, which includes automatic high beams, a lane-departure warning system, a blind-spot monitor, and a travel information display as well as an array of cameras that provide top-down and around-the-corner views.
On the upside, the M6 comes with an automatic stop-start engine function to conserve fuel at stoplights.
