Along with the new look, the next model will be considerably larger than the outgoing car.It will based on the VW Group’s MLB architecture, which also underpins the Audi Q7 and Bentley Bentayga.The Touareg’s proportions will remain close to those of the T-Prime concept, so a wheelbase stretched by 100mm and an increase in overall length of around 200mm is to be expected.The new platform will also bring with it a new batch of six and eight-cylinder engines. Two versions of a new 3.0-litre V6 diesel are likely,developing around 215bhp and 270bhp respectively, while a larger V8 diesel will also be offered to buyers.
