Audi S7 4.0 TFSI Quarter Mile - APR Stage I vs Stock
APR S8 Quarter Mile Comparison - Stock vs APR Stage I| 10/16/2013
The APR ECU Upgrade for the Audi S8 is generating a tremendous leap in power over the already incredibly fast setup from the factory. You can read more about the upgrade on our product page:
Yesterday we decided to see how much of a difference our software makes in a quarter mile acceleration test in several different forms. We tested with no modifications at all, other than replacement Michelin PSS tires for our factory 21 inch wheels.
In completely stock form the car put down impressive times as seen below. With 93 octane in the gas tank we also tried our stage 1 ECU upgrade and later filled in 100 octane, switched to our 100 octane race program and collected more data.
The results for such a large vehicle were nothing short than outstanding. We ran all runs in Sport mode with ESP off and Dynamic mode enabled. We made sure to turn off the air conditioning, including the massaging air-conditioned seats.
The results were as follows:

For the gear heads out there, this was performed at Montgomery Motorsport Park. We rented the track for the evening so it lacked the traditional prep and track temps that typically aid in getting the car off the line a little quicker with less wheel spin. Nonetheless, the car performed amazingly!
The vehicle was full weight, minus the spare tire too. Based on the time stamps and local we
APR S6/S7 Stage 2 Quarter Mile with APR Cast Race DP!| 02/08/2016
Using the upcoming APR 4.0 TFSI Cast Exhaust Race DP and new APR Stage II ECU Upgrade, we set out to test the C7 S6 and C7 S7 in various configurations, ultimately resulting in two new and exciting records!
The S6 was outfitted with the APR Stage II ECU Upgrade, APR TCU Upgrade, APR Cast Downpipes, 93 octane fuel and all season tires on factory wheels at full vehicle weight. With a 1.733 60 foot time, the best result of the day was an firstname.lastname@example.org MPH. The heavier S7 was outfitted with the same mods, but ran with Sunoco GT260+ 104 Octane fuel and Michelin tires on APR Wheels, again at full vehicle weight. With a 1.678 60 FT time the best result of the day was an email@example.com MPH! The density altitude remained close to 0 feet all day according to dragtimes.com. For comparison sake, our best results with the factory equipped vehicle was firstname.lastname@example.org MPH and email@example.com MPH using only our Stage I ECU Upgrade, and 93 octane fuel.
Over the course of the day, we ran several times, backing the 11.3 pump fuel results. We frustratingly backed the 11.0 multiple times, mere hundreds away from our goal of a 10.9 on factory turbo. The video does not show the fastest runs as those were captured after the film crew left as they had prior Super Bowl Sunday obligations.
On the dyno, the Stage II ECU Upgrade, paired with the APR Cast Race DP offers a substantial leap in power and torque, which contributes heavily to to the faster times at the track. Stay tuned for the official release
APR License Plates and Frames| 06/15/2021
APR license plate frames and vanity plates are the perfect addition for any APR tuned vehicle! They are made from sturdy and rust-resistant T304 stainless steel. They are thick enough such they won't flop around like throw-away handouts you find in a typical swag-bag at car shows. They feature a fade and scratch resistant black powder coated finish with laser etching for the APR logo. Anti-vibration backside plate tabs keep it firmly in place. Four slotted install holes give you the perfect fitment with a solid connection to the car. The nice hardware hiders give it a clean finish too, hiding your unsightly plate screws. Fitment is universal. Some have said this product will increase the value of the vehicle, while others have made horsepower gains, but we can't comment on either.
