APR S8 4.0T Acceleration - 0-120 MPH

Audi RS7 4.0 TFSI V8 0-140 MPH acceleration testing.

Gauges show a stock RS7 vs the same RS7 with an APR Stage I ECU Upgrade using 93 octane fuel.

The APR Stage I ECU Upgrade gives you higher peak numbers of 674 HP/700 FT-LBS on 93 (R+M)/2 octane and up to 728 HP/744 FT-LBS on 100 (R+M)/2 octane race fuel. As much as +162 HP and +223 FT-LBS of torque are available through the power band! APR's ECU Upgrade is the best power per dollar modification for the new 4.0 TFSI V8 and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory-like smoothness and drivability, APR's ECU upgrade will fill the void in an otherwise excellent car.

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.

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:

11.909@116.76 MPH with a 1.837 60 FT - Stock 11.174@123.01 MPH with a 1.769 60 FT - APR Stage 1 93 10.937@126.31 MPH with a 1.748 60 FT - APR Stage 1 100

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!
