The trio is made up of Caterpillar, MAN and mtu and for about ten years it has been raising the bar, with increases of 100 horsepower or so. Read the full comparison in the January issue of Powertrain International.
If this was a Netflix serial, it would probably be Game of Thrones. Without the low blows, intrigues and fantasy atmospheres, Game of Thrones corresponds to what the American sociologist Talcott Parsons would call "need for achievement". In summary, it is the crystal-clear expression of the three-way competition that has been unleashed in the 2,000-seahorse sector.
The trio is made up of Caterpillar, MAN and mtu and for about ten years it has been raising the bar, with increases of 100 horsepower or so. It all began in Friedrichshafen, indeed in Cannes, where mtu, in 2014, decided to enter forcefully with the V2000 M96, segmented with 10, 12 and 16 cylinders. A concentration of technological "delicatessens", such as the triple sequential turbo, the doubling of cooling stages (inter- and after-cooler) and of air filtration and the restyling of Bosch common rail nozzles and of the injection pump by L'Orange.
MAN did not resign itself to the muscular test of its compatriots and raised the power bar from 1,800 to 1,900 horsepower and subsequently to 2,000, focusing on top-of-the-range performance. And Caterpillar? The Americans relaunched two years ago, in the Covid-19 period, with a re-engineering, applied to the C32, capable of whipping the 2,000 horses up to 8 percent of navigation time. The power density reaches unexplored peaks due to the control logic of the ADEM 6 ECM control unit and the timing of injection cycle.
