Audi S4
Audi's quattro four-wheel-drive system was standard on the C4 S4/S6; a first-generation Torsen-based system which used the "T-1" automatically biasing centre differential (ATB) was used on vehicles equipped with manual transmissions, while a transfer box based system was used on vehicles equipped with an automatic transmission.
Ferrari 458
The only transmission available on the 458 is a dual-clutch 7-speed Getrag gearbox, in a different state of tune shared with the Mercedes-Benz SLS AMG. There is no traditional manual option, making this the fourth road-car after the Enzo, Challenge Stradale and 430 Scuderia not to be offered with Ferrari's classic gated manual. It is the first mainstream model to not be offered with a manual transmission.
