The 2017 Mack MP8 will be available for order in April 2016, while the 2017 MP7 and MP10 engines will be available for order in July 2016. The Mack MP8 with turbo compounding will be available for order in October 2016.
Both engines feature an updated wave piston design that raises the compression ratio and enables more complete combustion of fuel, while a common-rail fuel system “more precisely injects fuel”. Combined with a two-speed coolant pump, these features help increase MP7 fuel efficiency by up to 5.1 per cent and MP8 fuel efficiency by up to 5 per cent. And the new MP8 is 20kg lighter than the outgoing design.
Mack-badged engines and transmissions for the North American market are built at its powertrain facility in Hagerstown, Maryland. Mack is part of the Volvo Group, one of the world’s leading manufacturers of trucks, buses, construction equipment, marine and industrial engines.
