Reliable, Fuel-Efficient Engines
Challenger 600B Series combines feature two different engines, depending upon the model, to ensure the best application of power for the job at hand. New to the 660B and 670B models is a Challenger Endurance 84ETA diesel that has proven its strength and economy in the MT600 and MT600B Series tractors for more six years now. In the meantime, we’ve matched the Caterpillar C13 engine with the power demands of the Class VIIII Model 680B.
Challenger Endurance 84ETA engines combine a number of advanced technology features to deliver high performance torque and exceptional fuel economy from their 8.4-liter (513 cubic inch) displacement. Electronic Engine Management 3 (EEM3) continuously monitors engine performance and is capable of making up to 100 adjustments per second to precisely manage fuel delivery and timing.
