Our friends across the pond finally get to enjoy the new LS3 that's currently powering the Pontiac G8 GXP and Holden Commodore HSV, with the revised Vauxhall VXR8. The upgraded V8 has grown from 5,967 cc to 6,162 cc and is producing 425 hp at 6,000 rpm. Coupled with the revised automatic gearbox, 0-60 times drop to 4.9 seconds (from five), and the run from 80 to 100 mph is reduced from 4.3 seconds to four seconds flat. Fuel economy remains the same as the outgoing LS2 and automatic-equipped models now get a transmission cooler standard. The new VXR8 is currently on sale in the UK for £35,695, an extra £485 over the outgoing model.

New V8 for VXR8: same calories, fuller flavour
- New 6.2-litre V8 engine
- Improved in-gear performance
- Option of 20" alloy wheels
- Gearbox oil cooler standard on auto
- Addition of Heron White to colour palette
Vauxhall's mighty VXR8 super-saloon gets a potent new V8 engine this summer, with even more power and improved performance. The new unit allows the VXR8 to raise the bar yet again among its rivals, optimising its sophisticated rear-wheel drive chassis still further and retaining its mantle as a driver's car like no other in its class. New colour and equipment options further enhance this, the fastest car to wear the Griffin badge.
Known as LS3, the new V8 engine's capacity grows from 5967cc to 6162cc, and thanks to various improvements over the outgoing LS2 unit, such as high-flow cylinder heads, new pistons and an enhanced valvetrain, power is up by 14PS to 431PS at 6000rpm.
This translates to a reduced 0-60mph time for cars with automatic transmissions (down from 5.0 seconds to 4.9) and improved in-gear acceleration for manual models (50-70mph in 3rd gear drops from 2.8 to 2.6 seconds; 30-50mph in 2nd gear drops from 2.0 to 1.9 seconds). And if you fancy smoking your VXR8 at a track day, you'll see 80-100mph times fall from 4.3 to just 4.0 seconds in 4th gear.
Despite the VXR8's enhanced performance credentials, its LS3 produces the same emissions and fuel consumption as the outgoing LS2 unit. In addition, the VXR8 automatic receives a transmission oil cooler as standard.
Buyers for the LS3-engined VXR8s also receive the choice of an all-new body colour - Heron White – at no extra cost, as well as the option of factory-fit 20-inch rims for the first time on this model.
Prices for both manual and automatic versions of the LS3-powered VXR8, which are on sale now, rise by £485 to £35,695.
