=== LWR ===
The ''LWR'' is dedicated LPG 3.6-liter engine. Introduced in the MY2012 [[Holden Commodore]], Based on the 3.6-litre LY7 engine, the LWR had a vapour injection system. The vapour injection system injected gas directly into the [[air intake]] runner, thereby preventing excess gas from circulating through the air intake system. Although liquid LPG injection generally produces more power, [[Holden]] justified vapour injection on the grounds of lower fuel consumption, lower {{CO2}} emissions, reduced pumping and parasitic losses, and start-up reliability in hot weather.

The dedicated LPG LWR engine produced peak power and torque of {{convert|180|kW|PS hp|0|abbr=on}} at 6000 rpm and {{convert|320|Nm|lbft|0|abbr=on}} at 2000 rpm. The LWR engine was mated to GM's six-speed [[GM 6L50 transmission|6L45]] [[automatic transmission]] and, over the combined ADR 81/02 test cycle, the Commodore Omega achieved fuel consumption of {{convert|11.8|L/100 km|abbr=on}} – an improvement of 1.6 L/100 km compared to its dual-fuel LW2 predecessor. Furthermore, the LWR engine exceeded [[European emissions standards|Euro 6 emissions standards]].
* Specially hardened valves and valve seats.
* A redesigned cylinder head and manifold for improved air flow.
* Variable exhaust valve timing (the LW2 engine only had variable intake valve timing)
* Specially-developed fuel injectors.
* New pistons with pentroof-style centre-domes and valve eyelets for a higher compression ratio of 12.2:1 (compared to 10.2:1 for the dual fuel engine).
* A new fuel rail and a new LPG fuel filter.
