The current design direction of VW is an interesting one. Under the leadership of Murat Günak, who introduced the former VW design direction (where VW's had a face similar to that of the MKV GTI, R32 and Jetta and the Tiguan, Passat CC etc.), the styling for the brand was pushed up market with a dramatic, vertical front end graphic. When Martin Winterkorn (former Audi CEO) took over VAG, he installed the former chief designer of Audi, Walter de Silva to oversee the new design direction of the VW brand. This saw the new design direction that we see implemented today, with horizontal lines and much plainer, more simple detailing. In a word, the goal was to take the VW brand downmarket back to its original position, leaving Audi plenty of breathing space. The difference is stark. Take a look at some designs from the previous strategy:
And compare them to some designs under the new strategy:
The most dramatic example of the difference is the current Scirocco. The car began under one design direction and ended under another! Hence why the front end of the production car seems a little out of place with the rest of the vehicle.
Everything other than the front end is significantly more expressive than what we are seeing under the new design direction. Just compare it to this New Compact Coupe, for example. So everyone has their own opinion, but there's no question that after flirting with overt, expressive, sexy design, VW's returning to a much more conservative style. Some people like it, other people don't. Personally, from the front, I think the MKVI GTI looks much more bland and less impressive than the MKV. But then I prefer the taillights of the MKVI.
