Audi R8 V10-engined
Fourtitude Forums posted some spy shots that are believed to be the V10 version of the Audi’s supercar in testing at the Nurburghring.
The HH on the license plates and preproduction status of the R8 suggest this is a car owned by quattro GmbH. The side blade intake is rounded out for greater airflow to the motor. Also, a new sideskirt design on this particular R8 is similar in design to the skirts on the S5.
