German tuning house O.CT Tuning based its latest project on the 30th anniversary Golf GTI Edition 30 that debuted in 2006 with a unique exterior and modified interior. Given the car's already stand-out appearance, O.CT Tuning focused purely on improving performance and handling, managing to increase output to 365 horsepower and 369 lb-ft of torque by retuning the engine software, fitting an in-house intercooler and upgrading the air induction system.

Further modifications were required to get more from the special-edition GTI, so a motorsport intake system was installed, followed by special spark plugs, a modified injection system and a sweet-sounding 76mm racing exhaust system. Rounding off the package is a custom coilover suspension and carbon-fiber engine and battery cover.
