    The 3.6-liter Pentastar V6 engine with Variable Valve Technology is an All-New design featuring double overhead camshafts, Variable Displacement Oil Pump and high-flow intake and exhaust ports, dual independent cam phasing. That all translates into an exceptionally flat torque curve with 90 percent of the peak value available from 1,600 to 6,400 rpm. Outcome: smooth, responsive driving experience.

  • Fuel-saving technology
    Fuel-saving technology

    The 5.7-liter V8 engine features advanced fuel-saving technology that automatically deactivates four cylinders when eight are not needed. When cruising at highway speeds between 40 and 60 mph, MDS uses advanced computer technology and electronic throttle control to transform the engine seamlessly from V8 power to an efficient four-cylinder power plant in 0.04 seconds.

  • Is Your Timing Variable?
    Is Your Timing Variable?

    The 5.7-liter V8 features new state-of-the-art Variable Valve Timing (VVT) on the exhaust valves to substantially improve fuel economy and refinement, and maximize performance. By closing the intake valve later, the engine is able utilize formerly wasted energy to push the crank instead of rejecting it as heat.

     

    The new VVT improves fuel economy in two ways. First, it reduces the engine's pumping work by closing the intake valve later. Second, it increases the expansion process of the combustion event. This allows more work to be transferred to the crankshaft instead of being rejected out of the exhaust port as heat. Essentially, VVT improves engine breathing, which improves engine efficiency and power.
