The Audi S4 is one of the finest cars on the road. This car looks like your average family sedan, but that's where your wrong my buddy. This car comes stock with 250 horsepower, and 258 lb-ft of torque. This allows it to accelerate from 0-60 in 5.4 seconds. That is the speed of a stock Porsche 911 Carrera. What makes this car such a rocket is it's 6 cylinder twin turbo engine. The twin turbos spool up at lower RPM's to provide power that will suck you back in the seat. Here is a picture of the Motor.
The newest feature to Audi's motors are the 5 valves per cylander. The S4 has 30 valves which gives it more power.
The S4 also comes with a 5 speed tiptronic transmission (which shouldnt be availible) or a 6 speed manual transmission :)
The interior is just as beautiful as the exterior. The S4 will surround you in luxury.
18 inch wheels come stock on S4's, and 16 inch disk brakes also come on the S4 to help it stop on a dime. I can not forget the most important feature of the Audi S4. QUATTRO ALL-WHEEL DRIVE.
