Vauxhall is undertaking final UK development of a larger, lighter replacement for the Insignia, due to be revealed at the Geneva Motor Show next year as the Insignia Grand Sport.

The Insignia Grand Sport will debut at the Geneva Motor Show next year.

Launching as a five-door hatchback – Vauxhall has not confirmed whether saloon or Sports Tourer versions will be available later on – the new car is likely to feature styling adapted from the Monza concept shown in 2013.

It’s slightly longer, wider and lower than its predecessor, over a significantly lengthened wheelbase. Vauxhall is claiming a roomier interior and flagship-worthy technology on board, while lightweight materials in its construction mean it’s 175kg lighter than the outgoing Insignia.

Expect engines to include the full suite of 1.6-litre ‘Whisper Diesel’ engines from the latest Astra, with the more aerodynamic shape and reduced weight contributing to economy improvements across the range.

Rory Harvey, Vauxhall’s Chairman and Managing Director, said: “Vauxhall is raising its game even further with the launch of the new Insignia Grand Sport. It will set new standards for design, efficiency, technology and connectivity when it debuts next year at the Geneva Motor Show.”
