TrueDelta Reviews the Reliability And Durability of the 2015 Lexus IS

2015 Lexus IS Reliability And Durability: Pros
YearComment
2016 No matter how much Lexus improves the IS, the primary reason to buy one instead of something European or American (or even the Infiniti) will likely remain reliability. Audis and BMWs have become more reliable during the first few years of ownership, but once out of warranty they remain frightening propositions. Many remain reliable. But some owners live horror stories. The Infiniti Q50 has done well in TrueDelta's reliability survey but poorly in others. The key difference: we don't count software-based or usability issues that others do. The Q50's infotainment system has had issues. The G35 / G37 that preceded the Q50 has tended to be a better out-of-warranty bet than the Europeans, but some owners experienced excessive oil consumption and the odds of getting a lemon were higher than with the Lexus. full 2016 Lexus IS review
 

TrueDelta Reviews the Gas Mileage of the 2015 Lexus IS

2015 Lexus IS Gas Mileage: Cons
YearComment
2014 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. full 2014 Lexus IS review
2015 Lexus IS Gas Mileage: Neutral
YearComment
2016 With the turbo four engine and eight-speed automatic transmission, the Lexus IS's EPA ratings improve from 21 mpg city, 30 mpg highway to 22/33. Given that the highway rating improved much more than the city rating, more credit seems due the transmission than the engine. The Infiniti Q50 2.0t scores about the same as the Lexus, 23/31. The BMW 328i and Mercedes-Benz C300 have the best EPA ratings in the class, 23/35 and 25/34, respectively. full 2016 Lexus IS review
