Watch 2021 Audi RS7 Hit 226 MPH Thanks To Nearly 1,000 HP

What may look like a virtually standard 2021 Audi RS7 is hiding a big secret. Fitted with a stage 2 upgrade kit from German tuner HGP, this Sportback is both a beauty and a beast. Its twin-turbo 4.0-liter V8 engine has been massaged to deliver a whopping 962 horsepower and a mountain-moving 1,250 Newton-meters (922 pound-feet) of torque.

These are some healthy power gains when you take into account the standard RS7 Sportback makes 600 hp and 800 Nm (590 lb-ft). The massive boost is achieved by installing bigger turbochargers, an upgraded air filter box, and a modified downpipe. It also boasts larger-volume suction hoses and a remapped ECU, while the top speed limiter has been removed.

To put those amazing output numbers to the test, the car was taken at the Autobahn on one of the remaining unrestricted sections. It managed to reach 363.7 km/h or 226 mph, which represents a significant increase over the 305 km/h (190 mph) achieved by the RS7 when fitted with the optional RS Dynamic Package Plus.

Plot twist – the car reached that speed in seventh gear, so with one more gear available, it could’ve gone even faster. If you’re not particularly impressed by its high-speed capabilities, the 0 to 62 mph (100 km/h) sprint in 2.8 seconds should do the trick. It represents a drop of 0.8s compared to a regular RS7, while the 62 to 124 mph (100 to 200 km/h) task is achieved in less than five and a half seconds.

While HGP Turbo’s site says pricing for the stage 2 kit is available upon request, the car featured in this video costs around €200,000 with all the hardware and software upgrades installed. That’s a lot of dough when you consider the RS7 Sportback kicks off at €122,500 at home in Germany.

If you’re willing to settle for the stage 1 program, it costs €8,900 plus another €1,000 for installation. Power is bumped to 786 hp and 1,061 Nm (783 lb-ft), and it goes without saying you can have either of the two packages for the RS6 Avant and RS Q8 as well. In fact, the attached dyno run sheet belongs to the wagon.
