Volvo Trucks announced it has discontinued North American production of the 16 L Volvo D16 engine, effective immediately.
The decision also affects Mack Trucks, which is part of the Volvo Group.
According to Volvo, the decision to drop the D16 is the result of limited market demand for the 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, the company said.
The company also said that it continues to see a general shift among its highway customers toward the lighter, more fuel-efficient Volvo D13 engine which comprises the most popular engine displacement in North America.
Mack said its Titan model and its engine, the Mack MP10, were discontinued because many of the applications that the Titan served can be handled by Mack Pinnacle and Granite models equipped with the newer higher horsepower and torque outputs of the Mack MP8 13 L engine. Mack said it will continue to provide full aftermarket service and support to Titan customers.
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 company said.
The VNX model will remain in its product lineup and the company said it is evaluating solutions that will allow it to offer the engine in the future.
“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 company 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.
Aftermarket service and support will continue for customers who currently have a D16 engine, the company said.
