Following its world premiere at the 2017 Frankfurt Motor Show, Vauxhall has announced the prices for the all-new Insignia GSi, the performance variant of Vauxhall’s flagship model.

Available in both Grand Sport and Sports Tourer body styles, and powered by either a 2.0-litre turbo-petrol or 2.0-litre BiTurbo diesel engine, the Insignia GSi will be available from £33,375.

Arriving in Vauxhall showrooms in March, the GSi was developed at the Nürburgring in Germany, and is the fastest Vauxhall to have taken to the iconic track. At 160kg lighter than its predecessor – the Insignia VXR – the GSi features all-wheel drive with torque vectoring, mechatronic FlexRide chassis, Brembo four-cylinder brakes and Michelin Pilot Sport 4 tyres on 20-inch rims.

Buyers can choose from either the 2.0-litre 260PS/400Nm petrol engine, or the 2.0-litre 210PS BiTurbo diesel engine. Both units are paired with an eight-speed automatic gearbox with shift-paddles on the steering wheel, providing an active and responsive driving experience. In Grand Sport body style the Insignia GSi achieves 0-60mph in 6.9 seconds and has a top speed of 155mph.

The Grand Sport variant, with either engine option, is available from £33,375 on-the-road, with CO2 emissions of 197g/km (petrol) or 192g/km (diesel). Drivers looking for additional space can select the Sports Tourer body style, available from £34,875 on-the-road with either engine. The carbon emissions for this model are 199g/km for petrol and 192g/km for diesel.

Exterior design features include chrome air intakes, front and rear GSi bumpers, side sills and a large GSi rear spoiler (Grand Sport only), as well as incorporating Vauxhall’s innovative IntelliLux LED matrix headlamps. On the inside, the GSi features full-leather front sports seats, aluminium pedals, eight-inch colour information display with navigation, plus a Bose sound system and head-up display.

Four driving modes are available through the GSi’s FlexRide system, allowing damping, steering, gear change-up points and the car’s stability and traction systems to be configured according to a driver’s preference.
