Taking inspiration from the 2013 Monza concept and based on a revised version of GM's front-wheel drive Epsilon II platform, E2XX, the Grand Sport also tips the scales at 175 kg less than predecessor thanks to extensive use of lightweight materials with 60 kg alone being attributed to a technique known as body-in white.

Featuring a longer wheelbase and lower roofline than the outgoing model, the Grand Sport also introduces a raft of new tech, including Lane Keep Assist, Lane Departure Warning, Head-Up Display, unique AGR leather seats with front and rear heating, heated windscreen, Adaptive Cruise Control, Rear Cross Traffic Assist and the revised IntelliLux Matrix LED headlights.

GM has however remained silent on engine choices merely stating that the current six-speed automatic will be replaced by a new eight-speed, while all-wheel drive be offered on flagship models. In addition, the revised FlexRide chassis system now boasts a Drive Mode Control with three settings; Standard, Touring and Sport, which alters the ride, throttle response, dampers and gear shifts depending on driving conditions.

Set to go on sale in the United States as the Buick Regal and the NG Holden Commodore in Australia next year, the Insignia Grand Sport will officially debut at the Geneva Motor Show in March. It however remains unlikely to be offered in South Africa soon.
