Turns On-Ramps into Drag Strips
More Power Right Now
Launch Your Truck
"Torque Response" is engineering-speak for get-up and go power. And the DD15™ is 3 times faster than a Series 60®. Even fully loaded, you feel yourself launching up the on-ramps. A test-fleet driver with 20 years experience said, "It's like being in a jet."
All Purr, No Rattle
The DD15 is all purr: it's unlike any other engine you've ever heard. The multi-injection event capability of the ACRS system enables combustion rate shaping, which in turn makes the DD15 quieter in the cab and on the road. Combined with the stiff engine block that reduces noise vibration and harshness, it's a quiet ride. Because you want to feel the power, not hear the power for 10 hours a day.
Up to “Bonus” HP with Turbo Compounding
Get an extra kick of up to 50 “bonus” horsepower without spending an extra drop of fuel. It's called turbo compounding, and no other engine in North America has it. It works by converting a little heated exhaust, and feeding its power straight into the drivetrain. And that extra kick increases fuel mileage up to 5% at road loads.
“You push it down and you feel yourself physically being pushed back into your seat. You can feel it... like being in a jet.”
The Widest Torque Curve in the Industry
The DD15 flat-out pulls. It's got a torque curve as wide as Wyoming; the power's there all the time so you won't be grabbing around for gears on little hills or gusty highways. And down at 1,000 RPM, it'll still push you back into your seat. That means you'll get a punch off the line.
Multi-Torque
Reducing engine rpm will increase your fuel economy, but you need to increase torque to maintain equivalent performance. Detroit Diesel's multi-torque options allow customers to save money by lowering engine RPM and maintain performance with a multi-torque rating. Multi-torque can be spec'd to engage in cruise control and/or the top two gears of many of the transmissions offered in the DD15.
DDEC® VI: Consistent Where It Counts
If there's one area you don't want technicians re-learning, it's the electronics. And the DD15 uses the familiar DDEC® VI. You get all the power and control from the familiar DDEC® VI electronics systems that you're used to from Detroit Diesel's other engines. Expect precision in diagnostics and analytics at all times.
More Power to Stop, Too
The engine brake that's integrated with the DD15 gives you three levels of engine braking depending on the grade: bunny, steep, and uh-oh.
