King of the Lions: MAN 12-cylinder yacht engine now with 1,397 kW (1,900 hp)

Completely new, redesigned engine | Outstanding in its output class | Extended range of applications for yachts of over 100 feet

From 8 to 13 September 2015, MAN Engines will showcase their most powerful high-speed four-stroke diesel engine to date at the Yachting Festival in Cannes. The twelve-cylinder V engine with 1,397 kW (1,900 hp) bears the distinctive name V12-1900 and was specifically designed for use in luxury yachts of over 100 feet. The complete redesign of the injection, power train and cooling system has allowed MAN to achieve an increase in output of 74 kW (100 hp) compared to the established V12-1800.

With installation dimensions of 2,139 mm x 1,153 mm x 1,265 mm (length x width x height), the V12-1900 comes in the MAN Engines customary compact size. At 2,365 kg (dry weight) and as a result of the increase in output to 1,397 kW (1,900 hp), the most powerful series engine from MAN Truck & Bus has an outstanding power to weight ratio with a high power density and compact installation dimensions. This therefore gives architects and boat builders significant room for manoeuvre in terms of design. A maximum torque of 6,220 Nm, at 1,200 to 2,100 rpm, makes the V12-1900 the most powerful engine to date in the MAN Engines portfolio, thus delivering ample output reserves for overtaking manoeuvres and fun when piloting luxury yachts. The high-performance unit generates its power from 24.2 litre displacement ensuring high power development even at the lower end and right across a broad speed range. The even and constant acceleration delivers a pleasant and comfortable ride right through to the upper end of the speed range. The special design ensures very smooth running and thus provides a relaxed ride, adding to the comfort on board. “Our V12-1900 sets the benchmark in this output class in terms of dry weight, specific output and power to weight ratio” proudly commented Claus Benzler, head of Marine at MAN Engines. At its optimum, the specific fuel consumption of the V12-1900 is at the same low level of 190 g/kWh as its heavier sister model, the V12-1800.

The V12-1900 is MAN's response to the issue of increased performance for both planning and displacement hulls. At the same time and as a result of the increase in horsepower, the Bavarian-based engine manufacturer now has access to further types of ship with higher output requirements. MAN thus provides boatyards with a perfectly balanced range for all output requirements in leisure boating. The product range offers in-line 6-cylinder as well as V8 and V12 engines and covers the full range of performance from 537 to 1,397 kW (730 to 1,900 hp). All engines are also available in compliance with the strict EPA Tier 3 emissions standard. For those customers seeking something extra, optional gilded or chrome-plated cylinder head covers as well as a design cover are available. The engine can be ordered and delivered from now on.

The V12-1900 can be seen from 8 to 13 September 2015 at the Yachting Festival in Cannes on stand Jetee 138.
