All versions of the new BMW 5-Series Long-Wheelbase come as standard with eight-speed automatic transmission making an additional contribution to the car's efficiency just like EPS Electric Power Steering. The highlights of BMW EfficientDynamics on board the car include Brake Energy Regeneration, on-demand control of ancillary units, and active air flap control. Fuel consumption and CO2 are down versus the previous models by up to 18 per cent.
