The Cummins X12 weighs in at 2,050 lb., leaving it with the highest power-to-weight ratio among engines from 10 to 16 liters in size.

The Cummins X12’s 11.8-liter displacement puts it smack in the middle of medium-bore engines, but the ratings for horsepower and torque place it in the range of what some people might expect from a 13-liter engine. It weighs in at 2,050 lb., leaving it with the highest power-to-weight ratio among engines from 10 to 16 liters in size. It’s lighter than other 11-liter engines, too.

The final product delivers 455 hp at 1,400 to 1,900 rpm, and 1,700 lb-ft of peak torque between 1,000 and 1,400 rpm.

Not only that, but the X12 reportedly has half the number of parts used in other diesel engines, and the sculpted block has removed metal while retaining structural integrity. The composite rocker cover and oil pan sheds weight as well. And the integrated engine brake is said to deliver 50% more braking power than a traditional engine brake.
