Novelis Inc. supplies aluminum for the roof, doors, hood, side panels and reinforcements on the new BMW 7 series. The Canadian supplier, which is a wholly owned subsidiary of India's Hindalco Industries Ltd., also provides BMW a new multi-layered metal that the company calls "the new aluminum." The BMW 7 series is the first car to use of the alloy combination, which Novelis says is more corrosion resistance and more versatile than conventional aluminum. This means it can be used to designs parts to could not that could not be made before from aluminum. Autoliv Inc. supplies the optional night vision/pedestrian detection system for the BMW 7 series, which debuted at the 2008 Paris auto show. Using a grille-mounted high-resolution infrared camera, a computer alerts the driver that there are pedestrians at risk of being hit by the vehicle. The 7 series also is the first BMW to feature both lane-departure warning, from Germany's Continental AG and Netherlands-based vision specialists Mobileye N.V., and lane-change warning from Hella KGaA Hueck & Co. of Germany. The lane-departure warning uses a camera to monitor road markings. If the vehicle drifts out of the lane, the system vibrates the steering wheel to alert the driver of the problem. The lane-change warning alerts the driver if another vehicle is in the car's blind spots. Nippon Seiki Co. Ltd. supplies the vehicle's head-up display. Cars with head-up display and lane-departure warning include a speed-limit sign recognition system. BMW assembles the new 7 series in Dingolfing, southern Germany.
