A3 TDI Clubsport quattro
 

The Audi A3 TDI Clubsport quattro is a concept car unveiled in 2008. Based on the Audi A3 three-door, it is an approach by Audi to address both performance and the environment.
The engine in the concept car is a turbocharged 2.0-litre diesel producing 224 horsepower (167 kW) and 332 lb·ft (450 N·m). of torque. It produces 113.8 horsepower (84.9 kW) per litre while meeting Euro 5 Diesel emission standards. It uses the quattro drive system with a six-speed manual transmission.
The chassis has Audi's Magnetic Ride Suspension system, lowering the vehicle 1.4 inches (36 mm) from the base model. It also has ceramic front brakes, a four-link rear suspension and electro-mechanical servo assist for the rack and pinion steering.[8]
Exterior modifications include the widening of the three-door's grill, modifying the odd, and enlarging air intakes. Bolt-on fender flares and a large rear spoiler have been added. The interior changes include sport seats and a flat-bottomed steering wheel.[8]
Audi claims performance of 0 to 62 mph (0 to 100 km/h) in 6.6 seconds with a top speed of 149 mph (240 km/h).[9] It is expected to get approximately 40 miles per US gallon (5.9 L/100 km; 48 mpg-imp).
