The introduction of stricter regulations regarding emissions and the imminent introduction of unleaded gas meant that Holden did not have a compliant engine. To bridge the gap between the VK and the planned brand new model, Holden replaced the blue motor with the Nissan RB30 3 litre 6 cylinder engine while continuing with the albeit fuel-injected Holden 308 cubic inch V8.

The VL was also available with the RB20 2-litre 6 cylinder engine but only in New Zealand.
