LA 2008 Live: 2009 BMW 750 Li gets 400-hp and iDrive powered owner’s manual

The 2009 BMW 7-Series made its U.S. debut today at the 2008 LA Auto Show. The U.S. will get two variants of the new 7-Series including the 750i and the 750 Li. The outgoing 360-hp 4.8L V8 will be replaced by the 4.4L twin-turbo V8 from the X6 xDrive50i. That makes an outstanding 400-hp with a maximum torque of 450 lb-ft for the very-large sedan. Mated to a 6-speed automatic transmission, BMW says that fuel-economy was also improved but wouldn't give us any specific numbers. What they did tell us was that the 2009 BMW 7-Series will be the first car to get its own "Integrated Owner's Manual." What does that mean? That means your 2009 750i or 750 Li won't come with a physical book. Instead BMW will deliver the owner's manual electronically through the iDrive. What happens when iDrive fails to operate? Well, you figure it out. Follow the jump for more high-res photos from the show. 2009 BMW 750 Li - Live from 2008 LA Auto Show:
