Vauxhall VXR8 Gets 6.2L LS3 V8 Engine

Vauxhall has updated its UK-market Vauxhall VXR8, a badge-engineered version of the Holden HSV Clubsport. The Chevrolet LS2 engine under the hood has been replaced by the latest LS3, which is larger in displacement at 6,162cc versus the LS2’s 5,967cc.

Other than just raw displacement, the LS3 also has other advantages over the LS2 such as high-flow cylinder heads, and an enhanced valvetrain design.

Despite quite a few modifications, power goes up only by 14 PS, with the V8 now rated at 431 PS at 6,000rpm. Thankfully emissions and fuel consumption are rated the same as the outgoing LS2. Translated to road times, the VXR8’s 0 to 100km/h sprint time drops by 0.1 seconds to 4.9 seconds.

Other changes include a standard gearbox oil cooler for models with an automatic gearbox, and a new colour called Heron White
