Cummins new engines introduced and poised to meet MY2027 standards

Cummins has been busy these past few months. The company has introduced new engines across a broad range of engine sizes, applications, and fuel compatibilities. One thing common is that all are designed to meet the upcoming EPA MY 2027 standards.

Other than the re-designed powerful X15 workhorse which was announced last year, here are some more engines announced in these last few weeks:

(1) A first-ever gasoline B6.7 Octane engine with up to 300 hp and 660 lb-ft of torque. The engine uses a three-way catalyst only. Kenworth will be using the engine on its Class 5 – 7 trucks later this year.

(2) The B7.2 diesel engine for medium-duty applications with up to 340 hp and 1000 lb-ft of torque, with automatic engine shut down and start-stop capability for GHG reduction. This will enter production in 2027.

3) The X10 diesel engine with two ratings: medium-duty with up to 380 hp and heavy-duty with up to 450 hp. The engine is expected to replace the L9 and X12 engines and to be launched in 2026. Like the MY 2027 X15, the X10 will also have a 48V alternator which will power electric heater for low emissions.
