The D7 high-speed engine delivers a 1.5 – 5 MW output at 1,000 – 2,000 rpm is designed to serve a broad range of applications and sets new standards in fuel efficiency, power/weight ratio and TBO-intervals.


The D7 is characterised by its robustness, efficiency, compactness and strength. MAN Diesel & Turbo has targeted tugboats, workboats, offshore service and supply vessels, navy patrol boats, super yachts and fast ferries as its core applications.

The new engine will additionally serve non-marine markets such as the offshore, onshore power generation and rail segments. It will also be available as a gas-powered version for certain applications.


The D7 will play a central role in a new propulsion train devised by MAN Diesel & Turbo. Customers will be offered the engine as part of a package that includes gearboxes, propellers, switchboards, auxiliary gensets, and energy storage solutions. Orders for the new engine can be placed from 2014 on.
