Power Division - a relatively unknown Poland-based tuner- has announced a new Stage 4 kit for the Audi RS7. The Stage 4 kit increases the power to 1,044 horsepower and 883 lb-ft of torque. That's 453 hp and 293 lb-ft more than the standard V8, which produces 591 hp and 590 lb-ft. It's basically an additional RS5 powertrain under the hood. Naturally, this has an epic effect on the performance. The tuner claims a 0-62 mph time of 2.4 seconds, which is massively quick for an ICE-powered luxury cruiser. We're more impressed with the in-gear acceleration, however. It will get from 62-124 mph in 4.6 seconds. That means the Power Division Stage 4 RS7 accelerates quicker from 62-124 mph than a Bugatti Veyron.
