GREENSBORO, N.C. — Volvo Trucks North America has informed its dealers through an internal sales bulletin that effective immediately it will cease production and distribution of its 16.1-liter D16 diesel engine.
Aftermarket service and support for all D16s currently in the field will continue unimpeded.
The OEM informed its dealers of the decision Friday.
The internal sales bulletin was later leaked to one member of the media.
“The decision is the result of limited market demand for this engine displacement and the long-term investment that would be required to maintain the D16 for the unique operating requirements of the North American market,” a Volvo spokesman said. “We also continue to see a general shift among our highway customers toward the lighter, more fuel-efficient Volvo D13 engine which comprises the most popular engine displacement in North America.”
Although it could not be confirmed through a spokesman for Mack Trucks, the decision to discontinue the 16-liter engine production will also affect Mack.
Both Volvo Trucks North America and Mack Trucks are members of the Volvo Group.
Mack Trucks will reportedly stop offering its MP10 16.1-liter engine, which shares major design and production attributes with the D16.
Attempts to reach a Mack Trucks spokesperson to confirm the discontinuance of the MP 10 were not successful.
The D16 engine was available in Volvo VNL and VNX models.
The VNL will continue to be available with the Volvo D11, D13 and Cummins X15 engines.
“The VNX model will remain in our product lineup and we're evaluating solutions that will allow us to offer it in the future,” the Volvo spokesman said. “In the interim, we intend to offer an X-package for the VNL model, providing the ride height and heavy-haul attributes of the VNX with either the Volvo D13 or Cummins X15 engine.”
The spokesman said the package will include a 20,000-lb. front axle, dual steering gears, heavy-duty bumper, chrome grille, high ride height for improved ground clearance, and 500 horsepower versions of the Volvo D13 and Cummins X15 engines.
The Volvo I-Shift AMT is standard on trucks equipped with a D11 or D13 engine and manual transmissions are available as an option. The X15 engine is available with a manual transmission or the Eaton Ultrashift transmission.
Media reports said Mack's heavy-haul Class 8 tractor, the Titan, will be discontinued.
According to the reports, a Mack spokesperson said that decision was made because many of the applications that the Titan serves can be handled by Mack Pinnacle and Granite models equipped with the newer, higher horsepower and torque outputs of the Mack MP8 12.8-liter engine. Mack will continue to provide full aftermarket service and support to Titan customers.
No information was available on the percentage of Volvo Class 8 tractors had been equipped with the D16 engine.
Volvo’s D16 engine was introduced in early 2005 as OEMs were debating whether to meet new 2007 emissions standards with Exhaust Gas Recirculation (EGR) or Selective Catalytic Reduction (SCR).
Volvo chose EGR, as did all other OEMs except Navistar.
“This engine is for customers who haul heavy loads or need to maintain a high average speed through the mountains for reduced trip times,” said then-VTNA president and CEO Peter Karlsten. “And since it is paired with the bold new Volvo VT 880 owner-operator truck, it will be very popular with customers who seek a strong image and serious performance.”
In announcing the D16, VTNA said with plenty of torque, the engine is able to pull heavy loads up long grades without losing speed or needing to downshift, noting that the engine could propel the Volvo VT 880 up a 3 percent grade at 65 mph at 1,400 rpm while loaded to 80,000 pounds.
