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.

This all new power plant will enter the marine market without any immediate competitor, given its truly athletic construction and a dry weight (excl. transmission) of only 325 kgs. Compared with other marine diesel engines of similar output, the weight advantage will be far over 100 kgs per engine, while the running characteristics of TDI 265-6 will further contribute to put it into a class of its own:

The V-6 base engine with a capacity of 3 litres is one of latest designs in the engine portfolio of Volkswagen group, and otherwise found in luxury cars like Audi A 6, Audi A8, Q7 or the highly successful Volkswagen SUV "Touareg" and "Phaeton". This origin explains the extreme refinement of the engine at any power setting, made possible by its piezo controlled 3rd generation common rail injection system. The TDI 265-6 will deliver its 265 hp at 4.200 rpm, and produce 550 newtonmetres of torque at only 2.000 rpm, ideal to accelerate even heavier powerboats onto the plane.

An additional advantage of the new engine will be its extremely compact dimensions, especially its length of only 812 millimetres sets it apart from other marine diesels which are, in this performance class, mainly inline engines. Boat builders installing Volkswagen Marine TDI 265-6 will gain a big opportunity to use more space for storage or accommodation. The engine will initially be offered in sterndrive configurations with Mercruiser Bravo 1 and Mercruiser Bravo III.

Based on our bestseller TDI 150-5, this extremely silent, low emission five cylinder engine now offers 121kw, i.e. 165 strong and healthy horses. The additional 15hp were achieved by means of a modified injection system.

The engine?s cooling system, which was from the beginning designed for ample reserve, underwent some further upgrades as well.

The TDI 165-5 is primarily aimed at light, fast planing craft and will especially appeal to the ever increasing ?Rigid Inflatable Community?. As weight and dimensions are identical with the already sporty TDI 150-5, we can now offer an even better weight ? performance ratio: One horsepower is produced by merely 1,6 kilograms of engine (based on engine dry weight without sterndrive).

Five cylinders, 2,5 litre engine capacity, 111 kw (150 hp), direct injection with electronic engine management (MDC) and extremely low weight per horsepower that is our marathon champion for speedboats.

This exceptionally sturdy and refined 5 cylinder draws its power, among other factors, from a turbocharger with variable turbine geometry (VTG-charger) and from boost intercooling. The engine will brighten your day with a torque of over 300 Nm at any speed between 1700 and 3100 rpm, with low fuel efficiency and minimum emissions.

Easily meets EU standards and all expected future emission standards for marine engines.

For heavy boats (e.g. big sailing yachts) or semi-displacers, we recommend the TDI 120-5 for its wider engine speed range. Easily meets EU emissions standards and all expected future emission standards for marine engines.

Ample power, ample reserve! TDI, diesel with 2.5 litre engine capacity, favourable weight performance ratio and a mighty torque of over 250 Newton meter at any engine speed between 1900 and 3200 rpm.

Thanks to those characteristics, the perfect engine for a wide range of heavier boats - with all the fuel economy and low emissions that you expect from us.

Turbo boost out of 5 cylinders at a maximum engine speed of no more than 2.600 rpm!

In the particular case of this engine, our water cooled ?VTG?-turbocharger (Variable Turbine Geometry) primarily ensures extremely high torque at low engine speeds. This allows especially silent cruising and makes maneuvering in tight spots easy. An additional benefit of our charger is that its watercooling keeps engine room temperatures low, which is good for safety on board and assists engine efficiency.

This engine is intended as a special comfort solution for water displacing cruisers. For very heavy boats (e.g. big sailing yachts) or semi-displacers, we recommend the mechanically identical TDI 120-5 for its wider engine speed range.

Easily meets EU standards and all expected future emission standards for marine engines.

SDI engine with a wide and universally usable range of performance and torque. Direct injection via electronically controlled distribution injection pump (Marine Diesel Control). Extremely refined engine with favourable weight performance ratio.

The SDI 75-5 convinces not only with high torque, in excess of 150 Nm from 1.750 to 3.000 rpm, but also with its environmentally friendly characteristics such as low fuel consumption and low emissions.

Easily meets EU standards and all expected future emission standards for marine engines.

Thanks to its low engine speed levels a particularly comfortable power plant for cruiser on which silence and thrust are most important.

As a naturally aspirated engine, it is especially suitable for sail yachts whose engine is often started only for minutes of use, which means that normal running temperatures cannot be reached. Direct injection via electronically controlled distribution injection pump (Marine Diesel Control), low fuel consumption and low engine speed level for maximised comfort.

Easily meets EU standards and all expected future emission standards for marine engines.

Equipped with a very sturdy little turbocharger, this version is a direct response to market requests. In light of the engine’s huge mechanical reserves, 55 kW (75 hp) and an increased torque of now 155 newtonmeters at only 2000 rpm are still definitely conservative, but offer notable extra punch without compromising what this engine family was made for: Continuous, reliable and comfortable power supply at relatively low engine speeds.

The engine is ideal for anything from a 12 metre sailing yacht to small semi-planing boats with shaft drive, such as the ever more popular “pêche promenades” or small, yet quick cutter designs.

Easily meets EU emission standards and all expected future emission standards for marine engines.

The SDI 60-4 is the base version of our four cylinder marine engine. Correspondingly, the installed cooling capacity allows unlimited use of full power without any problem. Its relatively wide engine speed range makes it the most universal of the three versions and a favoured choice for larger sailing yachts. Its silent operation ensures comfort at cruising speeds, whereas the 44 kW (60 hp) offer an ample reserve of thrust. The favourable weight/performance ratio also makes the SDI 60-4 a nice option for small semi-planing craft.

Easily meets EU standards and all expected future emission standards for marine engines.

With an engine speed range up to 3.000 rpm, the SDI 50-4 offers some additional thrust whenever needed, e.g. for steaming against wind and seas. The overall engine speed level is still low, but slightly higher than in the case of SDI 40-4 as a lower-pitched propeller is needed in order to let the engine arrive at the rated 3.000 rpm and 37 kW (50hp).

Easily meets EU standards and all expected future emission standards for marine engines.

This is a low speed version of our four cylinder (max. only 2.600 rpm) and aimed at uses aboard small motor cruisers or Dutch sloeps, where greatest silence in operation is desired. At cruising speeds, 2000 rpm will hardly be exceeded although the base engine is designed for up to 4.800 rpm. As a result, the noisiest emission of an SDI 40-4 in a careful installation will often be the cooling water flow from the exhaust!
