one shared quality: reliable efficiency.

starter motor


A good starter motor should hardly be noticed by the driver – yet it plays a vital role: cold-start reliably, perform smooth start/stop operations and save fuel.

In the passenger car sector, we offer two technology platforms for different requirements: the C6 series, one of the world’s smallest passenger car starter motors with up to 1.2 KW, and the powerful C7 series, which can be scaled up to 2.0 KW. These platforms are the basis of the fuel-saving SC6 and SC7 start/stop starter motors, which are designed specifically for the high number of cycles required in start/stop and coasting applications.
