Thanks to the Australians, the hottest Vauxhall Insignia Grand Sport could get as much as 500bhp from a boosted V6
A hot version of the Vauxhall Insignia Grand Sport could reach UK showrooms with as much as 500bhp from a boosted petrol V6, thanks to Australian maker Holden’s in-house HSV tuning arm. That would be a huge uplift in power from the old Vauxhall Insignia VXR.
Sources inside GM suggest Holden Special Vehicles has been playing around with the new Insignia, extracting more than 500bhp from a fettled V6 – possibly with the addition of a supercharger. However, as is the existing trend for forced induction and reduced fuel consumption, turbocharging might make more sense for the production vehicle.
While the new Insignia Grand Sport is currently only available with turbocharged four-cylinder engines, the range-topper will allegedly use a six-cylinder motor. The Australian market has a penchant for high-capacity petrol engines – as proven by the powerful VXR8 and Maloo pick-up. With the outgoing Vauxhall Insignia VXR boasting 321bhp from a turbo V6, brand bosses see space above that car, aiming the yet-to-be-named hot saloon squarely at the BMW M3 and Mercedes-AMG C 63 S.
