VAUXHALL has announced prices for the all-new Insignia GSi, its new high-performance flagship model.

Available in 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 is priced £33,375 and arrives in UK showrooms in March.

The GSi was developed at the Nurburgring 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.

Engine specification is either 260bhp for the 2.0-litre petrol while the 2.0-litre BiTurbo diesel develops 210bhp. Both are paired with an eight-speed automatic gearbox with shift-paddles on the steering wheel.

In Grand Sport body style the Insignia GSi achieves 0-60mph in just 6.9 seconds and has a top speed of 155mph.

The Grand Sport variant has CO2 emissions of 197g/km for the petrol model and or 192g/km for the diesel which equates to a fuel return of 27.7mpg and 32.5mpg respectively.

The Sports Tourer estate is priced from £34,875.

Both models come with extra body kit that includes chrome air intakes, front and rear GSi-spedific bumpers, side sills and a large rear spoiler on the Grand Sport only. The cars are both fitted with Vauxhall's IntelliLux LED matrix headlamps.

On the inside, the GSi has full-leather front sports seats, aluminium pedals, an 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 preference.
