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

Lexus GS Real Gas Mileage: Cons
YearComment
In casual suburban driving the trip computer reported between 22 and 23 mpg, splitting the difference between the EPA ratings of 19 city and 26 highway. When I made the engine sing mpg dropped into the high teens. Slip into Eco and drive the GS like a Prius, and 25 is barely doable. Not bad for a 306-horsepower, two-ton, all-wheel-drive sedan. But the torquier Audi A6 3.0T and BMW 535i xDrive do a little better, especially on the highway. The Teuton's turbos help a little here, but most of the blame/credit goes to their respective transmissions. If and when Lexus fits the GS AWD with the eight-speed automatic already offered in the RWD car, it'll likely catch up. see full Lexus GS review

I have been averaging 26 MPG (indicated) in mixed suburban and highway driving, which I think is pretty good. see full Lexus GS review

For 340 hp and a 0-60 of 5.2 seconds, I consider an average of 24 in the city and 33 on the highway to be incredible. If you really feather the gas and stick to 65 on the highway you can get around 36-38 mpg. see full Lexus GS review

Low consumption in city and stop and go traffic Significant fuel savings in typical German highway driving - plenty of acceleration to and braking from high speeds. The hybrid drivetrain minimises the cost of this compared to conventional petrol power see full Lexus GS review
