VM 43 C

Select Units


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.

Low operating costs

HFO/MDO Anticipated TBO and life Long maintenance intervals and extended life form the basis for low operating costs.

Highly economical

Reliable HFO operation and low fuel and lubricating oil consumption, simple maintenance and long maintenance intervals ensure highly economical operation.

Resilient foundation

The resilient foundation system can be assembled safely, simply and cheaply and ensures the damping of vibration and structure-borne noise.

The successful origin

The modular design of the engine, the integration of various functions in one component, the robust structure and the use of components already proven in the in-line version lead to an outstandingly high level of reliability.
