After the success of the Q7, Audi decided to add a midsize SUV to the lineup and the Q5 was born. From the range of engines the 3.0T supercharged V6 is the most desirable though the 2.0T is no slouch. The 2.0T can be brought to 270 HP / 329 TQ with a simple stage 1 tune on pump gas and if you can find E85 ethanol fuel those #s increase to 313 HP / 388 TQ! The 3.0T supercharged engine goes to 425 HP / 364 TQ on stage 1 and an incredible 459 HP / 429 TQ is available at an APR Ultracharged tune level!
