Diesel engine V12-1900

In September 2015, MAN Engines presented this back then most powerful high-speed four-stroke diesel engine to the world public at the Yachting Festival in Cannes. The twelve-cylinder V-engine with 1,397 kW (1,900 HP) has the distinctive name V12-1900 and was specially designed for use in luxury yachts up to over 100 feet. The complete redesign of injection, engine 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 x 1,153 x 1,265 mm (length x width x height), the V12-1900 offers the compact dimensions familiar from MAN engines. Thanks to the power increase to 1,397 kW (1,900 HP), the extremely powerful MAN Truck & Bus series-production engine with 2,365 kg (dry) has an outstanding power-to-weight ratio with a high power density and compact installation dimensions. This allows architects and shipbuilders particular creative freedom. The V12-1900 is one of the most powerful engines in the MAN Engines portfolio, offering sufficient power reserves for overtaking manoeuvres and driving pleasure on luxury yachts thanks to a maximum torque of 6,220 Nm at 1,200 to 2,100 rpm. The bolide draws its power from its 24.2 litres of displacement, which ensures high power delivery even in the lower rev range while simultaneously providing it over a wide rev range. The balanced and constant acceleration behaviour, which extends into the upper rev range, provides pleasant driving comfort.
