  • ILX engine options offer power, efficiency or balance of the two
  • The three ILX powertrain choices include a hybrid
  • New V6-powered RDX has more power and better fuel economy

Acura recently released the official EPA fuel economy ratings for the redesigned 2013 RDX and the company's newest model, the compact ILX sedan.

All three engine choices in the ILX are fairly fuel efficient. When equipped with the optional hybrid powertrain, the ILX is rated to return up to 39 mpg. The ILX's base 4-cylinder engine delivers up to 35 mpg, while the sporty 201-horsepower version can get up to 31 mpg.

A V6 replaces the old turbocharged 4-cylinder engine in the 2013 RDX compact crossover, giving it more power and significantly better fuel economy than the old version.

The ILX is not just a new model for Acura, but also the company's first hybrid vehicle. The EPA rating for the gas-electric powertrain tops other ILX models, but is lower than the mpg ratings for other economy-minded, hybrid vehicles like the Toyota Prius. At 39-mpg city (where hybrid models tend to do best), the ILX hybrid's fuel economy falls between that of Lexus' two hybrid models, the 35-mpg HS 250h and the 43-mpg CT 200h.

With the optional 2.4-liter 4-cylinder gas engine, the ILX produces a peppy 201 hp and decent highway fuel economy of 31 mpg, but city economy is an unimpressive 22 mpg. The 2.0-liter base engine, also a 4-cylinder, provides a better balance of economy and power. Its 35-mpg highway rating is nearly as high as the hybrid's, and its 24 mpg-city rating is an improvement over the 2.4-liter. The base engine produces 150 hp, which might be 51 hp less than the bigger motor, but it's 39 hp more than the hybrid.

With its new V6 engine, the redesigned 2013 RDX is both more powerful and more efficient than the turbocharged 4-cylinder model it replaces. In thriftier front-wheel drive form, the 273-horsepower RDX returns 20 mpg in the city and 28 mpg on the highway, a gain of 1-mpg city and 4-mpg highway over the old model. All-wheel drive RDX models see even greater improvement. At 19-mpg city and 27-mpg highway, the 2013 RDX with all-wheel drive increases 2-mpg city and 5-mpg highway compared to the previous generation.

The 2013 ILX and RDX illustrate that while smaller engines and hybrid powertrains can provide good fuel economy, bit bigger, more powerful engines can be efficient, too. The hybrid version of the ILX is certainly the most efficient, but the base engine offers an appealing balance between power and economy. In the new RDX, a larger and more powerful engine actually provides better fuel economy than the model it replaces.

What it means to you: In the brand-new 2013 ILX, buyers can choose hybrid efficiency, sporty power or somewhere in between. The redesigned 2013 RDX, meanwhile, offers both more power and better fuel economy, with a more efficient V6 replacing the old turbocharged 4-cylinder engine.
