New 7 Series Bimmer Cuts Weight, Adds Features

BMW AG will take the wraps off its new 7 Series luxury sedan next week on the Internet ahead of its public unveiling in September at the Frankfurt auto show. Sales will start later this year.

Previous spy shots indicate an evolutionary design change from the current model, which was launched in 2008.

The sixth-generation 7 Series will retain the basic size and shape of the current model. In addition to standard and long-wheelbase versions, an extra-long-wheelbase model also is expected.

The lightweight modular design will save as much as 290 lbs, according to media reports. The rear-drive architecture uses a combination of aluminum, high-strength steel, magnesium and carbon fiber-reinforced plastic. All-wheel drive will be optional.

Other goodies include road-scanning technology with stereo cameras, LED headlights, and remote-controlled parking and semi-autonomous driving capabilities. In addition, the car's infotainment system will include gesture recognition software to control functions.

Engine choices will include a range of 4-, 6- and 12-cylinder gasoline and diesel units. A new 3.0-liter inline-six powerplant will be available with either two or three turbochargers. A 9-speed automatic transmission is standard. BMW is said to be evaluating an M performance version for the new 7 Series that would be powered by a 600-hp V-8. A plug-in hybrid derivative also is in the works.
