And here it is : the Top Gear Season 15 Episode 4 in which Clarkson reviews two topless German cars: the Audi R8 V10 Spyder and the Porsche 911 Turbo Convertible, which both cost as tested 113,500 GBP.
After both cars were driven by the Stig on the Top Gear track the Porsche 911 Turbo Convertible was slightly faster with a lap time of 1:22:2 while the Audi R8 V10 Spyder did it in 1:22:3
The rest of the Top Gear Season 15 Episode 4 continues with the boys being involved in a challenge where they each have two build motor homes, while the celebrity that gets to test his driving skills on the reasonably priced Kia Ceed 2 is Andy Garcia.
