Vauxhall is relaunching its range-topping Insignia VXR as the most affordable car to boast a supercar-rivalling 170mph top speed. Badged ‘Insignia VXR SuperSport’, its top speed is boosted by the removal of the speed limiter, which adds 15mph to its V-max.
At the same time, Vauxhall is slashing nearly £4000 off the Insignia VXR’s price by dropping it to £29,995.
There are no direct rivals to the VXR SuperSport as no other relatively affordable four-door saloon boasts a supercar-grade top speed. The Cayman S two-seater is the closest performance and price rival, with a 172mph top end and costing from £48,000.
Four-seaters with a 170mph top speed are even thinner on the ground. Autocar’s favourite BMW M5 boasts a 155mph top speed in standard form, and a £73,000 price.
The VXR SuperSport is not the first time that Vauxhall has launched a sledgehammer performance saloon. In 1990, when Vauxhall parent GM also owned Lotus, it turned the rear-wheel-drive Carlton executive saloon into a 176mph super-saloon.
Power came from a 377bhp twin-turbo 3.6-litre straight six. It was priced at £48,000, making the VXR SuperSport look good value in comparison.
The VXR SuperSport is powered by a 2.8-litre V6 engine, which gets a forged steel crank and alloy sump. It is equipped with a single twin-scroll, turbocharger.
The engine develops 320bhp and drives a torque-sensing all-wheel drive system. The car has adaptive damping and the sophisticated HiPer strut suspension at the front end in place of the conventional MacPherson struts fitted to mainstream Insignias.
The SuperSport can sprint from zero to 60mph in just 5.6sec and is identified by the blue ‘Brembo’ lettering on the brake calipers and a recalibrated speedo.
