If at all that is true, then the current Mk 6 model cycle would be the shortest among all Golf generations. The Mk 5 was after all running from 2003 to 2009 while the preceding Mk 4 Golf production has equal longevity from 1997 to 2003.
Could it be that the current generation of Golf Mk 6 uses a slightly modified platform of the Golf Mk 5? And that the overall dimensions and silhouette shadows much of its predecessor? Perhaps in German automotive application just a major facelift of the Mk 5?
As such, the Golf Mk 7 will be a completely new model. To be built on a new platform known as MQB - which will have a longer wheelbase yet lighter - the all-new 2012 Golf will allow the introduction of hybrid powertrains which include petrol-electric and diesel-electric combos. The Mk 7 Golf will probably sport a full-EV variant rumoured to debut a year later in 2013.
The all-new Mk 7 Golf is expected to be unveiled by end 2012, with production target for the Mk 6 to be around 1.6 millions units. In contrast, the Mk 5 with its good-and-ripe 6-years production run had clocked up some 2.3 million units.
