D9512 A7

Liebherr is presenting its D9512 diesel engine, a brand-new V12 high-end unit that develops up to 750 kW (1,020 hp). It is a significant upward extension to the Liebherr diesel engine range. The powerful new V12 diesel is designed for the extreme practical requirements of modern construction machinery operation, and is notable for its high torque of up to 4700 Nm, dynamic power flow over a broad engine-speed range and low fuel consumption. Its unusually compact dimensions are a further advantage

Liebherr diesel engines have a high specific output and high torques in a large range of speeds while maintaining excellent operating values. They can withstand the harshest conditions such as extreme ambient temperatures and thanks to their integrated engine management systems they can be used at high altitudes. Liebherr’s many years of experience and constant improvements using the latest simulation and calculation methods guarantee reliability and longevity.
