The 2012 MDX uses a 3.7-liter V-6 engine that provides V-8 level power while retaining the size and fuel efficiency of a 6-cylinder engine. The 3.7L develops 300 horsepower and 270 lb-ft of torque to provide quick throttle response, outstanding low- and mid-range torque and excellent high-rpm power. To widen the powerband while simultaneously improving fuel efficiency, the 3.7L V-6 has the patented Variable Valve Timing and Lift Electronic Control system applied to the intake valves, a computer controlled dual-stage intake manifold and an electronic Drive-by-Wire™ throttle system.
