The Acura RDX's turbo four is still a bit of an anomaly in the small luxury SUV/crossover segment. It's peppy but it certainly isn't as fast as it's V-6 equipped competitors. This is an acceptable trade-off for the much higher fuel economy returned by a four-cylinder engine, right? Well, not in this case. Despite being much lighter, having far fewer horses, and having a significantly lower engine capacity than the V-6-equipped competition, the RDX manages only marginally better fuel economy. The Acura's combined average is 24; a number matched by the BMW X3 and the Lexus RX350 and only missed by 1 mpg by the Infiniti EX35 and the Audi Q5.
Once you remove fuel economy from the "positives" column, the only thing the Acura RDX does better is undercut the price of the other vehicles in its segment. Unfortunately, the hard plastics throughout the interior will be a constant reminder of the money you've saved.
