New | VM 43 C Marine Propulsion Engine

Developed to meet the requirements of the cruise ship and ferry markets, this new engine series is the breakthrough into a new class of power. Designed state-of-the-art, engineered to lead. After the successful introduction into the market of four new engine series in only ten years, the extension of the program continues with a further engine - the VM 43 C engine. The 12 and 16 cylinder V-version of the M 43 C doubles the power on offer from Caterpillar to 16 MW and therefore supports new and important market segments and groups of customers.
