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.
