600 lbs Lighter in 2018? The Weight is Worth It.
At 2050 lbs, the X12 is especially designed for weight-sensitive applications. Up to 600 lbs lighter than other medium-bore engines and 150 lbs lighter than the next lightest engine in its class.

What can you carry with 600 more lbs?

30 more cases of soda in your delivery truck

97 more gallons of fuel in your tanker

10 more bushels of corn in your grain hauler

Productivity has a new liter. 12.

Weight reduction is only important if the engine can also get the job done efficiently, day in and day out. The X12 was designed to be a left lane truck with right lane fuel economy. It has the performance and transient response that impresses even the big bore truck drivers while maximizing fuel economy in regional haul and local duty cycles.

Up to 500 HP and 1700 lb-ft of torque

Revolutionary low-friction design for higher MPG

Maintenance intervals that rival the X15 with longer Oil Drains and DPF maintenance beyond the first owner

Compatible with a broad choice of transmissions: fully automatic, AMT and manual
