On the 21st  and 22nd of May 2010 Sport Auto organized once more the Tuner Grand Prix and the Drift Challenge at the Hockenheim Ring. It was the first time Arden took part at this meeting and with the AJ 20 XKR 5,0L Cabriolet they immediately gained second place within the vehicles category. Even though they had a realistic chance in the drift challenge, the decision was eventually made over the Tire selection.  In spite of this the Arden Cabriolet advanced to be the crowd’s favorite and caused a sensation with the incredible drifts. The Cabriolet had already impressed the sport auto in the 5/2010 edition that had previously tested the vehicle. The Arden AJ 20 made it into the top group and was placed before the BMW Motorsport 6 Cabriolet, the Mercedes SL 63 AMG and the production XKR Jaguar Coupe.
