The North American performance specialists from STaSIS present their latest upgrade program for the Audi S5 Cabriolet, called the Challenge Edition,
Dubbed the Challenge Edition, the model features a supercharged 3.0-liter V6 that has been equipped with a revised ECU and a stainless steel sport exhaust system.
The vehicle now deals with the 0 to 60 mph sprint in 4.3 seconds ( an improvement of 0.7 seconds). As for the handling, this should match the straight line performance, as the tuner installed a set of adjustable shock absorbers and also upgraded the brakes, using Alcon six-piston monobloc calipers, high performance pads and stainless steel brake lines.
A 'road-gripping' differential was also fitted, plus the car now rides on 20 inch ultra lightweight forged aluminium wheels wrapped in high performance low profile tires. As a result lateral acceleration has dropped from 1.00 G to 0.86 G while brake deceleration dropped from 1.00 G to 0.89 G.
