GTI Weltklasse. The VW Golf GTI is an especially potent mix of practicality and performance, but it’s never been in the same league as sports cars and supercars for obvious reasons. But it looks like that’s about to change with the VW Golf Design Vision GTI, unveiled at the Worthersee tuning festival in Reifntiz. For all its fancy design lines you can instantly tell the concept VW is part of the Golf lineage. But make no mistake, under the bonnet is something a bit special. It has a six-cylinder, twin-turbocharged 3.0-litre engine that produces a trouser-ruining 496bhp and 413lb/ft (560Nm) of torque.
