Acura ILX Real Gas Mileage: Pros
Year	Comment
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

Lexus LS Real Gas Mileage: Cons
Year	Comment
	Nearly everyone except Toyota has been transitioning to boosted engines for fuel efficiency at least as much as for performance. While boosted engines swill gas at least as well as their unboosted equivalents when hustled, in typical driving they are more efficient. With EPA ratings of 16 mpg city, 23 mpg highway, the LS 460 nearly matches the Jaguar XJ AWD (16/24), but falls well short of the Audi A8 3.0T (18/28) and BMW 740Li xDrive (19/28). In the real world, the Lexus's fuel economy lags the others, including the Jaguar, to an even greater degree. In our suburban driving the LS 460's trip computer often reported averages between 15 and 16, vs. low 20s in the Jaguar. A light foot could nudge the LS's average to 18, but the XJ's to 25. On the highway the LS 460's trip computer reported averages of 24.7 and 23.3. The XJ's reported just over 30. see full Lexus LS review

2001	0	In United Kingdom (Imperial) gallons and miles, over the last 60,000 miles I have averaged 24.6mpg. In town it falls to about 15mpg and on a long run at 85mph (normal cruising speed on UK motorways despite 70mph limit) it returns 27.5mpg see full Lexus LS review
