Further proof that Audi is more than simply an alternative brand.

#6. Quattro with Sport Rear Differential promises even better handling.

Much like Acura’s Super Handling All-Wheel Drive (SH-AWD) system, the new quattro with Sport Rear Differential offered on the 2010 Audi S4 is able to distribute engine power not only between the front and rear axles, but also between each rear wheel. This technology directs a greater percentage of torque to the outer rear wheel while cornering, which helps to limit understeer and improve handling and stability.
