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 14hp to 431hp at 6,000rpm.
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).
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.
Prices for both manual and automatic versions of the LS3-powered VXR8, which are on sale now, rise by £485 ($956) to £35,695 ($70,353).
