The 2027 X10 platform undergoes extensive field and engineering testing validating its performance across multiple vehicle brands and applications. This includes performance stress, extreme environment conditions and customer field tests.
Globally the X10 has 6 years of research & development, 54,500 hours and 8.8 million on-road testing. For North America, the X10 is targeted to accumulate 4 years of research and development, 12,620 hours of in-house and overload testing and 2.5-million-miles of on-road testing at launch.
The X10 delivers the best of both worlds—big-bore performance in a lighter, more efficient package designed for both HD and MD applications.
With up to 320–450 hp and 1,650 lb-ft of torque, it’s about 100 pounds lighter than the X12 and improved fuel economy built upon Cummins’ Uptime legacy.
Consequently, the X10 integrates the lessons learned from the L9 engine, while only being 159lbs heavier meeting space claims for mid-size fleets. Designed to punch above its displacement, the X10 provides the power customers expect—with added efficiency and confidence when transitioning to next generation technology.
