The register lists here 2 versions from the 2016 to 2020 model years, each with 293 kW rated output at 4,300 rpm, running on sequential fuel injection for petrol and LPG. Maximum torque stands at 372 Nm at 4,000 rpm, certified for the US market under the EPA engine family LPRLE06.05P0.
Dual-fuel petrol/LPG engines go into commercial vehicle fleets where LPG is meant to serve as a cheaper or locally available fuel alongside petrol, for instance in municipal or delivery vehicles. Certification through a specialised service provider rather than the vehicle maker itself is common for such gas-operation conversions.
When buying used, what counts on these dual-fuel engines is the condition of the gas system, pressure regulator and vaporiser alongside the classic check of the ignition system and injectors, and on commercial-vehicle use the operating hours and service history; spare parts for the underlying GM V8 engines are available through the general commercial-vehicle trade, and for the gas system through specialised conversion workshops.
