Kia Forte Real Gas Mileage: Pros
YearComment
2019 The Kia Forte's EPA fuel economy ratings of 30 mpg city and 40 mpg highway aren't quite best in class, but they're close. Unless you include the 55/49 Honda Insight and the 53/52 Toyota Corolla Hybrid in the class--then they're not so close. In my real-world suburban driving I observed trip computer averages in the low 40s in the Forte, similar to a 2016 Civic LX with a similarly sized, similarly non-turbo engine. A Civic EX, with a turbocharged 1.5-liter engine, should do a few mpg better. In the hybrid Honda Insight, I observed suburban trip computer averages in the 60s, but "only" 40 mpg on the highway, not even as good as the non-hybrids. see full Kia Forte review
Kia Forte Real Gas Mileage: Cons
YearComment
I've made it through the top reasons to buy a Kia Forte SX, but no mention of performance and handling (the reasons to upgrade from lesser trims) yet. But neither is the top reason not to buy one, either. Okay, maybe handling is. I'm trying to decide as I write this. Handling definitely isn't the car's largest weakness. That would be fuel economy. With a manual transmission, the Kia Forte SX achieves worst-in-class EPA ratings: 22 mpg city and 29 mpg highway. (The automatic goes a mile farther on each highway gallon.) Mind you, the Civic doesn't do much better, with 22/31. But the big-engined Mazda achieves 25/37 with a manual, and a lofty 28/39 with an automatic. And the much quicker Volkswagen GTI scores 25/34 and 25/33, respectively. The Forte EX, with its larger but non-turbocharged engine, is more competitive: 24/33 with the manual and 25/36 with the automatic. Maybe the Forte SX just doesn't test well. In my suburban driving the trip computer reported averages between 25 and 40 (depending on the frequency of stops and the heaviness of my right foot), with most in the low 30s. The trip computers in the Honda, Mazda, and Volkswagen all reported about the same. The Kia's trip computer also reported better-than-EPA averages on the highway, but not by as wide a margin. Short gearing restricted 70-mph-highway averages to about 33, well short of the high 30s observed in the others. see full Kia Forte review

2012 4dr Sedan 156-horsepower 2.0L I4

After many trips up and down the eastern USA coast (NY-FL and back) It has proven itself reliable and seems to do very well on the highway. Available power is decent, and fuel mileage is really good. It's unusual f we don't get at least the rated 33MPG but usually are between 35 and 38 with a full passenger load and moderately filled trunk. see full Kia Forte review

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

At around 200hp, it isnt the fastest luxury sedan. However, on my roadtrip across the eastern / mid eastern USA I was able to get ~33 ish mpg (computer reported) on flat terrain and premium fuel. City mpg is what I expect,22-25ish. But I think it is great as a long distance comfortable vehicle. see full Lexus IS review

Wish it got better fuel economy for such a small car and engine... Sticker is 21/29, I'm averaging 27MPG (computer read); avg on hwy is about 33-34 mpg while city is about 19-23mpg. Engine variety would help, a 4 cyl + turbo or something, but toyota/lexus isn't exactly known for that. see full Lexus IS review

For a small, relatively modestly powered car, it gets poor economy. Corvettes and most Porsches get better economy. see full Lexus IS review
