As usual the rumours were true, with HSV today announcing the arrival of the GM LS3 engine which is to be fitted standard across the HSV range from April.

The upgrade will see the ClubSport R8, GTS, Senator Signature, Maloo R8 and WM Grange’s power output rise to 317kW, up from 307kW.

The 6.2-litre LS3 engine is currently manufactured by General Motors Powertrain in North America and is used in the current Chevrolet Corvette.

In its HSV guise, maximum output of 317kW is achieved at 6000rpm, with maximum torque of 550Nm at 4600rpm – this is compared to 321kW and 424Nm achieved in the Corvette at near identical rpm.

Surprisingly, despite the added displacement, the LS3 engine will deliver a slight improvement in fuel economy for both the Maloo R8 and WM Grange, whilst the short wheel base models deliver 14.5L/100km as opposed to 14.4L/100km with the current LS2.

HSV’s export range will also receive the new LS3 powerplant, which includes the Vauxhaull VXR8 in the United Kingdom and the CSV R8 sold in the Middle East.

The obvious issue presenting current E-Series HSV owners is the logical blow to their resale value, with the LS2 having been made redundant by the now standard LS3.
