Cummins Unveils First-Ever Gasoline Engine
Cummins is a household name in the heavy-duty segments. The Ram Heavy Duty pickup is a good example. In a surprising twist, the diesel engine manufacturer recently unveiled its very first gasoline engine.
With the signature 6.7-litre displacement, the new Cummins B6.7 Octane aims to deliver the performance and durability of a diesel engine with the simplicity and lower maintenance costs of a gasoline engine. It is designed for medium-duty SUVs, trucks, buses and vans.

Four different output levels will be available, ranging from 200 hp and 600 lb-ft of torque up to 300 hp and 660 lb-ft. In the latter case, peak torque is delivered from just 1,800 rpm, which is very close to the 1,400 rpm of the B6.7 diesel unit. On the other hand, it remains accessible up to 3,200 rpm, according to preliminary figures provided by Cummins.
What's also important to know is that the B6.7 Octane uses an all-new, lighter engine block than its diesel counterpart. Other benefits include the absence of diesel exhaust fluid tanks and service intervals comparable to those of a conventional diesel engine. Cummins is talking about engine oil changes every 24,000 km.
Production of the B6.7 Octane gasoline engine will begin in 2026, with the first units reserved for Cummins’ OEM chassis partners such as Kenworth. It's too early to say when they’ll be available in Ram trucks or similar competitors.
