MAN Engines sets new standard with V12-2000 and V8-1300 yacht engines

MAN Truck & Bus Press Release  /  September 5, 2018

The highest power density on the market: MAN V12-2000; the strongest V8 engine in the yacht sector: MAN V8-1300; world premier at the 2018 Cannes Yachting Festival

At the 2018 Cannes Yachting Festival, MAN Engines will debut two new innovations which stand out from their competitors due to their unique nature: MAN engineers have developed the V12-2000, which is the only twelve-cylinder V-engine with 2,000 hp (1,471 kW) to date, which generates enormous power from 24 litres of displacement. Likewise, the strongest V8 engine for yachts and sport fishing boats on the market is the newly introduced V8-1300, which puts forth 1,300 hp (956 kW) from 16 litres of displacement.

Both the V12-2000 and V8-1300 engines impress with extremely high power densities of 61 kW and 59 kW respectively per litre of displacement. The minimal space requirement and low weight spell out a clear advantage in terms of ship design, when compared to similarly powerful engines with larger displacement and more cylinders. This is because the installation dimensions of the V12-1900 and the V8-1200 – the formerly highest power levels – have been retained, as they were already compact. These dimensions are 2,159 x 1,153 x 1,272 mm (length x width x height) for the V12-2000, and 1,736 x 1,153 x 1,222 mm (length x width x height) for the V8-1300. The dry weights of 2,380 kg (V12-2000) and 1,880 kg (V8-1300) have also remained the same; through a power increase of both engines, this also contributes to a noticeably lower power/weight ratio of 1.62 kg/kW for the V12-2000, and 1.96 kg/kW for the V8-1300. “With the V12-2000 and the V8-1300 we have set a new benchmark for performance and compactness,” says Claus Benzler, Head of Marine MAN Engines, delighted.

Through a series of modifications, MAN engineers have managed a power increase of 100 hp (74 kW) respectively, compared to the previously most powerful V12 and V8 engines from their range. The performance-oriented design is supported by an improved injection system and new turbo charger. This is aided by newly developed cylinder heads and an adjusted cooling system which noticeably provides thermal relief for the engine with its high performance. Additionally, a new crankcase which has been reinforced in significant areas, ensures high performance throughout the entirety of the engine’s long service life. Highly efficient combustion allows the V12-2000 and the V8-1300 to run quietly, as is typical for MAN Engines, and with low fuel consumption.

The V12-2000 offers customers the most powerful engine above the V12-1900, the previously most powerful engine, from the MAN Engines range. The superior engine performance allows shipyards to access additional possibilities for equipping larger ship series of around 100 feet with MAN engines. Additionally, as the most powerful V8 engine on the market, the V8-1300 makes it possible to integrate the highest-performing engines into existing applications. “Our MAN engines have always offered performance at the highest level. We currently stand out to a great extent in the market with the V12-2000 and the V8-1300, and will continue as such in the future,” says Benzler.

Both engines meet the currently applicable emissions requirements US EPA Tier 3 as well as IMO Tier II, and can thus be operated in all common and popular areas. With the introduction of both new engine types, MAN Engines offers a gap-free power range for yachts from 730 to 2,000 hp (539 to 1,471 kW) for V8 and V12 engines as well as the following inline six-cylinder engines: i6-730, i6-800, V8-1000, V8-1200, V8-1300, V12-1400, V12-1550, V12-1650, V12-1800, V12-1900 and V12-2000.

The V12-2000 and the V8-1300 can be viewed from 11 to 16 September 2018 at the Yachting Festival in Cannes on the Jetée 171 and 178 stands.

Looks like Navistar will have a host of V engines to choose from. Scania and Man 16 liter engines.

KS, was that particular v8 offered in trucks not long ago?

Yes, the 16.2-litre was offered in the TGX.

How does the MAN 16 liter compare to Scania 16 liter.

I'm biased, but they're both extremely good. The Scania V8 architecture allowed it to evolve forward and meet all current emissions standards. MAN decided to introduce the 15.2-litre D38 inline six, which is a wonderful powerplant. Drivers love the sound and performance of the Scania V8, and accountants smile approvingly at its fuel economy.

Is the Scania v8 like the EMD V's where you can remove the cylinder power pack as one unit. ( EMD 567-710 great design)

Individual cylinder heads. From back in 1969, Scania purchased the Mack V8 block but adapted it to individual cylinder heads for several reasons. A cylinder head covering more than one cylinder imposes restrictions on the maximum potential for achieving efficient intake and exhaust flow, because provisions for cooling and clamping compromise cylinder head design. Since individual cylinder heads don't suffer from these obstacles, the head design can be optimized for rapid gas flow to achieve maximum fuel efficiency. And regarding maintenance, it's far cheaper and faster to remove and reinstall an individual cylinder head, than a single cylinder head covering two to six cylinders.
