Acura ILX Real Gas Mileage: Pros
YearComment
2016 High-revving largish fours aren't the fashionable route to fuel efficiency. But the 201-horsepower 2.4-liter engine when mated to an eight-speed dual clutch automated manual transmission (DCT) returns EPA ratings of 25 mpg city, 36 mpg highway--better than the 2013-2015 ILX managed with a 150-horsepower 2.0-liter engine. The Audi with its au courant 180-horsepower turbocharged 1.8-liter checks in a little lower, with 23/33. But the Acura isn't quite best-in-class. The Mercedes-Benz CLA250 manages 26/38. Notably, both the Audi and the Mercedes also have DCTs, though with "only" six and seven speeds, respectively. Then there are hybrids and diesels. The ILX used to be available as a hybrid. But the ILX Hybrid's fuel economy wasn't stellar (39/38) and its performance was so uncompetitive even compared to the Prius-based Lexus CT 200h (43/40) that Acura killed it after just two model years. The Audi A3 TDI, the segment's lone entrant with a diesel, rates 31/43. For a combination of performance and fuel economy, it's hard to beat. Except that as I write this Audi dealers can't sell them, pending an investigation into whether they violate EPA regulations. A final note on fuel economy: the TLX's EPA figures are only a single mpg lower than the ILX's. see full Acura ILX review

Why doesn't Acura offer the larger four-cylinder engine with an automatic transmission? Likely because its fuel economy is already iffy with the stick. The EPA ratings are 22 MPG city, 31 highway. One benefit of turbochargers is that they enable lower rpm shifts and taller gearing. A Jetta GLI matches the Acura in the city, and does a couple MPG better on the highway. Not bad, but you'll find some much more powerful, much larger cars that score better than either of them. see full Acura ILX review

2010 4dr SUV turbocharged 210hp 3.0L V6 Diesel
7-speed shiftable automatic AWD		 Excellent. We average 27 on the highway travelling at 70+mph see full Mercedes-Benz R-Class review
2009 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD		 Pleasantly surprised by first tankful. 16.2 mpg in the city. Mostly used "comfort" setting which starts out in 2nd gear and shifts early. With this nonaggressive profile, city driving economy is improved. Premium gives better gas mileage than regular (about 5% on comparable tankfuls). On Comfort setting, no difference in performance is noted. see full Mercedes-Benz R-Class review
2008 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD		 It easily gets to 20 mpg on highway. About 18 on mixed driving see full Mercedes-Benz R-Class review
2007 4dr SUV turbocharged 215hp 3.0L V6 Diesel
7-speed shiftable automatic AWD		 Excellent fuel economy with the diesel, especially when driven gently. Also amazing power at the same time see full Mercedes-Benz R-Class review
2007 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD		 15mpg city....25 mpg highway....combined is around 17-18 mpg. Not bad considering how heavy this car is. Of course i am very light to the pedal trying to keep my mpg high. Gas is too expensive nowadays so if i don't need to be fast, i am keeping it steady. see full Mercedes-Benz R-Class review
2006 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD		 Much better than expected for a very large and long vehicle. Close to 25MPG on longer trips. see full Mercedes-Benz R-Class review

2007 4dr SUV 302-horsepower 5.0L V8
7-speed shiftable automatic AWD		 F-E is poor because of the weight to power ratio. The vehicle is heavy. With the available power, it is easy to drive faster and to maneuver through slower traffic. Frequent acceleration results in lower gas mileage. see full Mercedes-Benz R-Class review
2006 4dr SUV 268-horsepower 3.5L V6
7-speed shiftable automatic AWD		 I would probably choose a diesel next time for efficiency reasons - but the additional premium fuel required in the V6 is negligible once the car is paid for....soon now. Very lively engine too. I foresee a hybrid R class type vehicle after 2011... see full Mercedes-Benz R-Class review
