Automated manual transmissions made by Magneti Marelli are called “Selespeed” in Alfa Romeo cars, “Dualogic” in Fiat cars, and “D.F.N” () in Lancia cars. Other cars using similar gearboxes are the
Ferrari 355 F1 and
Aston Martin Vanquish. The base system is similar in all cars but the speed of operation is usually faster in higher priced cars. BMW's first generation SMG was also partly a Magneti Marelli system. Also Fiat, Lamborghini, Maserati, Mercedes-Benz, Renault, Peugeot and Citroen used the Selespeed system. ==Notes==
