The Cat D7E Track-Type Tractor uses an electric drive system that delivers 10 to 30 percent greater fuel economy, greater productivity and lower lifetime service costs. The D7E meets the increasing demand for powerful, maneuverable, fuel-efficient dozers that have the versatility to work effectively in both production dozing and fine grading applications. The overall efficiency of the new D7E results from its ability to better deliver engine power to the ground. This efficiency means the D7E can use a smaller engine. In addition, the engine runs in a narrow speed range (1,500-1,800 rpm) to further reduce fuel consumption and extend engine life.
