Automotive & E-Mobility

Since 2006, WITTENSTEIN has set benchmarks worldwide for power density, efficiency and intelligence for the drive trains of electric and hybrid vehicles. Our catalog includes traction drives, generators and electric drives for turbochargers and compressors, including smart control software. Our unique engineering solutions and serial products are especially used in space-restricted applications or for small serial quantities. Virtually no other organization can compete with our comprehensive mechatronic knowledge of the entire drive train.
