Volvo Trucks North America announced to its dealers back in January 2017 that effective immediately, the OEM would cease production and distribution of its 16.1-liter D16 diesel engine. Aftermarket service and support for all D16s currently in the field has continued unimpeded. While that took a bit to become effective, there were no 2018 model year engines built.
The decision to cease 16-liter engine production will also affect Mack Trucks, a sister company under the Volvo Group. Therefore, Mack will stop offering its MP10 16.1-liter diesel, which shares major design and production attributes with the D16. Volvo made that decision based on limited demand for the large-displacement diesel and the long-term investment that would be required to keep it in the market.
