It's amazing how cars can be modified to surpass its own limit.
This Audi A4 2.0T Quattro is one of those cars that was modified to meet the standards of a tracking car.
Chirstian Miller, accomplished many of his plans with the A4, which became a multi-purpose race car. Christian is the driver, but the car is owned and built by 034Motorsport. Speeding through the race tracks like lightning and making sharp turns wasn't enough for this beast. The next project was to change the specifications of the car to make it rip through the Redline Time Attack road course.
Many modifications need to be done in order to get a decent time completing the Time Attack course and one of them is reducing the overall weight of the car. The previous R32 head/24v block motor was swapped to a lighter 4 cylinder 20v motor, which was capable of pulling 600HP. Other heavy parts of the car was swapped to lighter but reliable ones, which helped the car to accelerate much faster and increase its handling.
