AUBURN HILLS, Mich. ---- Just a few simple tips can help owners of Chrysler Group engines with Multi-Displacement System (MDS) get the most fuel mileage possible from their 5.7L HEMI V-8 engine. Chrysler Group advises that driving habits that can maximize fuel savings with this technology include: · Keeping speeds to 65 mph or below - MDS uses four cylinder mode most at these speeds. · Use cruise control - this helps maintain a steady speed, generally allowing the HEMI to run on four cylinders for longer periods. · Accelerate more gradually - the HEMI will provide V-8 power whenever it is requested by the driver. · Use a steady throttle whenever possible - this maximizes four cylinder mode. The Chrysler Group MDS is standard equipment with the 5.7L HEMI on seven vehicles: the Chrysler 300C, Dodge Charger R/T, Durango, Magnum R/T, Ram 1500, and Jeep Grand Cherokee and Commander.
