Today there are over a dozen DCT manufacturers. These include Borg-Warner, Eaton, FEV, Ricardo, and perhaps the two most prolific transmission suppliers of all, ZF and Getrag (both from Germany).
Borg-Warner supplies or co-develops dual-clutch transmissions with the world’s biggest producer of DCT-equipped cars — Volkswagen (with Audi). Volkswagen calls its dual-clutch gearboxes “DSGs,” while Audi refers to them as “S Tronic.”
ZF, meanwhile, makes Porsche’s famous PDK gearbox. PDK stands for Porsche Doppel Kupplung, which is German for Porsche Double Clutch.
Getrag, on the other hand, makes DCTs for a vast number of car brands and models: BMW (for the M3 and Z4), **Chery (on both the turbocharged Tiggo 7 and seven-seater Tiggo 8), Chrysler, Ferrari, Ford, Mercedes-Benz, Mitsubishi (for the Lancer Evo X), Peugeot, Renault and Volvo.**
