13 May 2021 - We recently had a chance to take our 2021 Audi S4 to a 1/2 mile airstrip racing event, to test software development with Stertman Motorsport. The car is running full E85 on stock fuel system, with other hardware being stock. The vehicle was run in full weight trim, on stock wheels and tires (drive to the event, race and drive home).

Density altitude for the day was hovering around +2000 feet. While not the best DA for setting records, it is good for testing purposes. Overall, we were pleased with the performance for a basic stage 1 setup, achieving the following performance results:

0-60 MPH: 3.95 Seconds

1/4 Mile: 12.06 @ 115.70 MPH

60-130 MPH: 11.61 Seconds

Stay tuned for further development and testing!
