Vehicles with the new 2-speed drive consume less energy, which in turn extends range by up to five percent when compared to a one-speed unit. For vehicle manufacturers, the new 2-speed drive offers two options for using improved energy conversion efficiency. The Original Equipment Manufacturer (OEM) could either go for an extended range while retaining the same size of accumulator, or utilize a smaller accumulator.
Moreover, the 2-speed concept offers benefits for OEMs who are pursuing performance. Until now, with electric motors, vehicle manufacturers have had to choose between high initial torque and a high top speed. ZF engineers are now resolving this conflict and the new drive will be compatible for performance and heavier vehicles – for example for passenger cars towing a trailer.
