TDi 350-8 High End Diesel Power for luxury speed boats
Audi’s 4.2 litre V-8 diesel is an engine without precedent and without immediate competition. Being offered only aboard exclusive, power oriented vehicles like Audi Q7 and A8, this engine serves those who wish to be pushed back into their seats whenever they only touch the accelerator.
While its sheer torque is equivalent to sizeable truck engines, the engine offers exceptionally civilized manners. Piezo-controlled common rail injection, the typical refinement of a modern V-8 engine and uncompromising engineering allow this power plant to be nearly inaudible, unless its huge power potential is challenged.
Major players in the quality boating world have demanded this engine ever since first stories were heard about it, and now that the marine version is ready, its potential truly offers new options for boat design:
Its wide engine speed range allows easy application and propeller choice, enabling low maneuvering speed without trolling valve and exceptional acceleration.
Its immense power allows replacement of big block gasoline V-8’s without sacrifices in top speed, whereas acceleration onto the plane will be stunning to anyone who is used to gasoline power
Fuel savings against gasoline options will approach 50% in typical uses, extending range correspondingly.
A dry weight of the fully marinizied unit around 450 kilograms along with extremely short engine build invites more fuel capacity, additional accommodation or storage.
