But for such as the BMW 7 Series, the rear passengers feel the need to take special care of the top luxury models, rear comfort level is a measure of the level of the vehicle key indicators of success. Compared to the front-wheel drive and rear-wheel drive, four-wheel drive is most excellent driving stability, power output is more balanced, four-wheel drive can therefore ensure maximum grip, thus effectively reducing understeer and oversteer situations. Especially in the face of inclement weather and special road conditions, such as rain, snow, or potholes hit the road, the road surface friction coefficient becomes low, four-wheel drive in addition to traveling to ensure the stability of the vehicle's comfort will be improved accordingly.
2010, 750Li xDrive models marks the birth of intelligent all-wheel drive system officially applied to the BMW's flagship models.

With advanced eight-speed automatic transmission, with an average fuel consumption of only 8.4 liters / 100 km, carbon dioxide emissions of 189 g / km, compared with the previous models reduced by nearly 20%. Both dynamic performance, or fuel economy, the new 740Li xDrive are the leading competitors.
The new 740Li xDrive in luxury with equally doing my part. Parallel to the BMW EfficientDynamics strategy, BMW BMW interconnected driving innovation in science and technology has become another important pillar.
