Car tester Klaus Neidzwiedz says Volkswagen has sold 2 million Golf GTIs since the model first came out in 1976. The newest Clubsport edition has arrived just in time for the GTI’s 40th anniversary. And Klaus says it’s special. New technology enables it to produce 290 horsepower. Klaus is going to put the GTI through its paces at the Portimao racetrack in Portugal.
