French motoring magazine, Option Auto, drives TechArt’s Panamera GrandGT. Wearing an aggressive carbon fibre body kit, this Panamera Turbo enjoys the benefits of the TechArt TA 070/T1 power kit. This helps to release an extra 80 hp – resulting in 580 hp. That means the sprint to 100 km/h (62 mph) takes just 3.8 seconds, while the top speed is 315 km/h (195 mph).
