2017 Vauxhall Insignia Grand Sport to be brand's flagship model

The Vauxhall Insignia Grand Sport will sit above two other all-new Insignia models in the brand's 2017 line-up as one of five new models to be launched.

The 2017 Vauxhall Insignia Grand Sport has been revealed

The Grand Sport hatchback will be joined by two estate models, the Insignia Sport Tourer and a more rugged Country Tourer that'll come with four-wheel-drive as standard. Autocar sampled a development version of that car's system earlier this year.

We'e also driven a prototype version of the 2017 Insignia Grand Sport, and early impressions suggest the new name will be accompanied by a more eager chassis set-up. The car won't make its official debut until this December, however.

Design

The new Insignia will be larger, lighter and more efficient than the current model; the biggest changes are a small elongation of the wheelbase and the shedding of around 150kg.

It will be a truly global car, sold under the Vauxhall, Opel and Buick badges in Europe, the US and China. Here in Britain, it will remain a key rival to the Ford Mondeo.

The new Insignia will have an evolutionary look, with only minor styling changes to bring it into line with the rest of the Vauxhall range. Although the spotted cars wear cladding that hides the majority of the styling, it's clear the new model has a new swooping roofline, which is higher and wider at the rear.

As well as increased rear space and easier access to the rear seats, thanks to the taller door openings, the second-generation Insignia will get a bigger and more useable boot. A new tailgate design with new tail-lights will help to make the boot deeper, wider and taller boot than before, with a 565-litre capacity, matching that of the Skoda Superb.
