General Motors L8T

The register lists here 5 versions with 243 to 350 hp rated output at 2,500 to 4,500 rpm. Four of the five engines run on petrol, one on ultra-low-sulphur diesel; injection is sequential fuel injection on three engines and direct injection on two. Maximum torque ranges from 284 to 750 Nm at 1,400 to 4,500 rpm, the certification model years range from 2012 to 2026.

Engines of these designations power heavy pickups, chassis-cab platforms and vans sold under the Chevrolet and GMC brands in the North American market; the parallel listing of petrol and diesel versions with a similar engine-family scheme shows GM's typical dual-fuel strategy in the heavy segment.

When buying used, operating hours and service history count, on the petrol versions the condition of spark plugs and injectors, on the diesel version the injection system and exhaust aftertreatment, plus the cooling system and the condition of the engine mounts; since these engines in heavy commercial vehicles are often run under trailer load, it is worth checking the clutch or automatic transmission and its cooling. Spares and service run through the GM authorised workshop network.
