Never thought I’d see the day. Cummins, the name every diesel guy swears by, just built its first gasoline engine in 100 years. It’s called the B6.7 Octane.
It’s built off the same 6.7 liter straight six they’ve been putting in diesel trucks forever, except this one runs on plain 87 octane and fires with spark plugs. It’s turbocharged and makes up to 300 horse and 660 lb-ft of torque.
The selling point is no DEF and no regens, just a regular catalytic converter like your wife’s minivan. Cummins says it’ll go 15,000 miles between oil changes, and they put 2 million test miles on it before letting it out the door.
Kenworth is putting it in their medium-duty trucks first.
The real reason this exists is the EPA and California making diesel such a headache that Cummins had to build a gas motor to sell trucks. When the regulations get bad enough that Cummins starts building gas engines, something has gone sideways.
