DON’T worry, and be happy folks, because not only has Volkswagen not messed up the Golf GTI formula (like it did big time with the 1991 Mk3 and 1998 Mk4), it has actually improved the species thanks to a trick new electronic diff, a more efficient engine and improved quality all round. But the basics are as before, down to the driver-focussed chassis and everyday practicality, meaning that the new Mk6 GTI is as deserving of the widespread affections as its already-classic Mk5 predecessor was.
