Level 3 highly automated driving, which allows drivers to take their hands off the steering wheel and temporarily divert their attention away from the road, will soon be available in the new BMW 7 Series. BMW Personal Pilot L3 is the name of the new function that relieves the person at the wheel of the task of driving in certain situations and controls the car’s speed, distance to the vehicle ahead and lane positioning for them. This new option can be ordered for the new BMW 7 Series (excluding the i7 eDrive50 and i7 M70 xDrive)* from December to be fitted in vehicles from next March.
