It has a 10.2:1 compression ratio, Sequential multi-port fuel injection, and a bore and stroke of {{convert|94x85.6|mm|in|2|abbr=on}}. Lower-powered versions only have variable cam phasing on the inlet cam (LE0). Selected models also include variable exhaust. The engine weighs {{convert|370|lb|kg|abbr=on}} as installed. This engine is produced in several locations: St. Catharines (Ontario), Flint Engine South (Michigan), Melbourne (Australia), Ramos Arizpe (Mexico), and Sagara (Japan) by Suzuki. Suzuki's engine designation is ''N36A''. The dual-fuel {{convert|235|hp|kW PS|0|abbr=on}} ''LW2'' version was able to run on petrol and [[autogas]]. The LW2 engine was based on the low-output LE0 V6. It featured a factory-fitted dual-fuel system developed by IMPCO, different valves, and hardened titanium valve seats. This motor was available exclusively in Holden vehicles from 2005β2012.

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}} β 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.

In essence, the twin-turbo 3.6L V6 is the forced-induction variant of the popular LFX V6 found in the Cadillac ATS, XTS, and SRX, among many other GM models, with several important upgrades, including: * All-new cylinder block casting * All-new cylinder head castings * Strengthened connecting rods * [[Forged steel]] crankshaft * Continuously variable valve timing * Large {{convert|38.3|mm|in|abbr=on}} intake valves and {{convert|30.6|mm|in|abbr=on}} sodium-filled exhaust valves * Machined, domed aluminum pistons with top steel ring carrier for greater strength * 10.2:1 compression ratio * Patented, integrated charge air cooler system with low-volume air ducts * [[Twin-turbo|Twin turbo]]chargers produce more than {{convert|12|psi|kPa|abbr=on}} * Vacuum-actuated [[wastegate]]s with electronic control valves * All-new direct injection fuel system * Tuned air inlet and outlet resonators, aluminum cam covers, and other features that contribute to exceptional quietness and smoothness Applications: {| class="wikitable" style="font-size: 90%" |- !
