BMW released a lengthy press release on the new revised 650I, so we'll cu to the chase and layout some of the more interesting details.
The only major upgrades outside are the restyled front end, and LED tail lamps. Inside you will have the choice of a Sport Automatic transmission which has the addition of paddle shifters, matched with a sport button for even quicker shifting for spirited driving. The shifter is now shift by wire. A system very similar to that in use on the 5 series.
The interior has been revised with new leathers, brushed aluminum panels and revised iDrive. A new Active Cruise Control has been developed that can work in dense traffic and can handle the car coming to a complete stop and resuming to its pre set speed from 0MPH. A new sport package will also be available with upgraded handling, and wheel options.
Power comes from a 4.8 liter V8 engine with 360 Hp. Up from this years 4.4 liter V8 with 325 Hp.
