STaSIS unveils the S5 Cabriolet Challenge Edition

Article by Christian A., on May 31, 2011

STaSIS Engineering has finally revealed what may be the greatest version of the Audi S5 Cabriolet, the 410 bhp Challenge Edition. Based in West Virginia in the U.S., STaSIS is famous for its no-compromise principle. As such, the Challenge Edition gets a unique mix of upgrades in braking, with improvements in the chassis, and a more unified powertrain.

This results in boosting the supercharged 3.0-liter of the 2010 Audi S5 Cabriolet even higher. While there are faster cabriolets, none of them offer four seats. For the first time as well, the Challenge Edition will now be available for purchase by British customers. This new version is available at VAG specialist and APS of Brackley, authorized STaSIS distributor in the U.K.

Due to the combination of the improvements on the brakes, its more consistent handling, and the power increase of 23%, everyone inside the Challenge Edition is ensured of safety aside from getting to experience its high performance.

One of the changes done was that the ECU was remapped in order to increase the output from the default 333 bhp to 410 bhp. For the brakes, the version uses the Monobloc 6-piston Alcon calipers with two 370-mm floating discs on the front. It also makes use of high performance pads with the brake lines in braided stainless steel. To improve the ride comfort, the suspension utilizes the Ohlins SL dampers that come with double digressive damping. Spring rate was increased which allows for improved response. The suspension even allows for the ride height to be adjusted.

The exhaust has the Quad outlet T304 which is made of stainless steel with its tips laser engraved. It also has resonators that can be tuned for high rpm. To match the increased power, it has the forged aluminum 10.5x20-inch lightweight wheels equipped with the low profile and high performance tyres. Everything the company’s engineers learned at the race track was refined to the upgrade package of the S5 Cabriolet, making it comfortable to drive in the city or running through open road.

Acceleration from 0 mph to 60 mph is merely 4.3 seconds, though stock is at 5.0 seconds. With the Challenge Edition, STaSIS decided to focus on releasing its competitive behaviour and thus enhancing technology developed for races with Audi’s luxury. The Challenge Edition does indeed have a performance that is geared for racing. This includes the sure-footedness and agility provided by the road-gripping differential, Ohlins suspension which extends the suspension.

Other features that make this vehicle great are the exhaust that has been upgraded and the power output and torque that have been increased. Starting from the concept and up to the actual productions, each of the components has been examined to make sure that it reaches reliability at factory levels.
