TrueDelta Reviews the Real Gas Mileage of the Lexus IS

Lexus IS Real Gas Mileage: Cons
YearComment
The 2014 IS 350 manages 19 mpg in the EPA city test, and 28 in the highway test. While these figures tie those for the Cadillac ATS 3.6, they're short of the 23/33 achieved by the BMW 335i. Also, with both the BMW and the Cadillac you can step down to more efficient turbocharged four-cylinder engines. With the new IS, your only other engine option is a small V6, and its fuel economy is only a couple mpg better than that of the big V6 (21/30). The BMW has a further advantage: you can set the steering and suspension to "Sport" without forcing the transmission to hold a lower gear. In the 2014 IS 350 F Sport, the sport modes are "all or nothing." Select one to firm up the steering and suspension, and the transmission won't shift beyond sixth gear, reducing fuel economy. Lexus should follow Audi's lead and offer an "Individual" mode, where each system (powertrain, steering, suspension, etc.) can be set separately. see full Lexus IS review

TrueDelta Reviews the Real Gas Mileage of the Hyundai Elantra

Hyundai Elantra Real Gas Mileage: Pros
YearComment
2021 With EPA ratings of 31 mpg city and 41 mpg highway, the Hyundai Elantra Limited with a 2.0-liter engine and CVT is among the most fuel-efficient non-hybrid compact sedans. Lesser trim levels score even better: 33 city, 43 highway. Though the Kia Forte has the same powertrain, it scores a couple mpg lower. For even better fuel economy, the Elantra is offered as a hybrid with EPA ratings as high as 53 mpg city, 56 mpg highway, and 54 mpg combined. The Honda Insight and Toyota Corolla Hybrid manage only 52 mpg combined. One trim of the Prius (a hatchback) manages 56, but the others check in at 52. In my winter suburban driving I observed trip computer averages between 30 mpg and 40 mpg. see full Hyundai Elantra review
Hyundai Elantra Real Gas Mileage: Cons
YearComment
Hyundai has been among those manucturers offering turbocharged engines in "eco" variants of its cars. But as tuned for the Elantra Sport, the corporate 1.6T engine doesn't score well in the EPA's tests: 22 mpg city, 30 mpg highway. You'll find similar numbers on the window sticker of a Nissan sedan--if that Nissan sedan happens to be the 300-horsepower Maxima. The Sentra SR Turbo scores considerably better, especially in city driving: 26/32. I've unfairly implied the 1.6T engine is to blame. Hitch this engine to the seven-speed DCT instead of the six-speed manual, and it rates much better, about the same as a Sentra SR Turbo with its optional CVT, 26/33 vs. 27/33. Does the Elantra Sport manual's real-world fuel economy differ as much as the EPA ratings suggest? Or does it suffer from test anxiety? I suspect the latter. In my suburban driving with economy-minded acceleration and braking the trip computer reported an average of 37 mpg (with an occasional 40). see full Hyundai Elantra review

2013 4dr Sedan 148-horsepower 1.8L I4
6-speed manual FWD		 Just don't seem to be able to hit any of the gas mileage reported amounts. 10 to 15 litres per 100 KM seems to be the norm with combined city and highway driving. Dealer keeps telling me I need to "break" the vehicle in to get good gas mileage. Range odometer doesn't reset to 591 kms on fuel ups either. Takes several fill ups before it seems to work correctly for a while. Dealer can't find any issues with it. see full Hyundai Elantra review
2012 4dr Sedan 148-horsepower 1.8L I4
6-speed shiftable automatic FWD		 This is one of the most disappointing aspects of the 2012. The Active Eco is no longer anautomatic feature, and I've found I don't get the great gas mileage that I used to. I would consistently get 40mpg highway, and about 30 mpg in the city. Now I get 32 highway, 28 city. My parents live an hour and a half away, and I have other family living further away. I find it frustrating that I don't get the great mileage I did previously, especially since gas prices just keep going up. see full Hyundai Elantra review
2009 4dr Sedan 138-horsepower 2.0L I4
4-speed automatic FWD		 Engine is 132HP PZEV, not 138 SULEV. Diff in power seems smal but is significant for this car. Mileage worse AND power is less. Unfortunately, states dictate what you can get; CA emissions rule for PA = stupid cop-out/liberal cave-in to greenie-weenies see full Hyundai Elantra review
