Acura Swaps RDX’s Turbo Four for V-6 in Revamped 2013 Model

Automaker says decision was made to improve fuel economy.

Acura has made the curious decision to replace the 2.3-liter turbocharged four cylinder in the RDX with the venerable 3.5-liter V-6. The reason? Fuel economy.

Acura is revamping its RDX crossover in attempt to return to its core values, but the decisions regarding the second-generation small crossover seem to go against the current convention.

The 2013 RDX will trade its turbocharged 240-horsepower 2.3-liter four cylinder for Honda’s venerable 3.5-liter V-6, producing 273 horses. The larger engine is a surprise as almost every other automaker is frantically replacing their V-6 engines with turbocharged four cylinders precisely for the reason Honda says it is moving to the V-6.
