Turns On-Ramps into Drag Strips
More Power Right Now
Demand it all. Fuel efficiency, power, torque, durability,
quiet. Here's what drivers and fleets said.
Launch Your Truck
“Torque Response” is engineering-speak for get-up from a dead stop. And the
DD15™ is 75% 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.”
Up to 50 Free HP with Turbo Compounding
Get an extra kick of up to 50 free 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 — using fuel you would’ve
burned anyway — 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.”
Torque Curve? More like a Torque Plane
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 and on gusty highways. And down at 1,100 RPM, it’ll still push you back
into your seat. That means even with a governor on the engine, you’ll get a
punch off the line.
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 Jacobs-designed engine brake that’s integrated with the DD15 gives you
three levels of engine braking depending on the grade: bunny, steep, and
uh-oh.
