TrueDelta Reviews the Reliability And Durability of the 2015 Lexus NX
||As a rule, all-new cars aren't the best bets for reliability. But one reason Toyota has become so slow to join new trends is it doesn't want to jeopardize a reputation that took decades to build, and that was threatened not long ago by the unintended acceleration fiasco.
The Lexus NX 200t is powered by Toyota's first turbocharged gas engine since the 1990s, and Lexus's first ever. But this new engine has no doubt been subjected to some of the most thorough testing in the history of the industry. Just about everyone not Japanese, including Ford / Lincoln, introduced a 2.0-liter turbocharged four-cyinder engine much earlier.
The new engine, like those in competitors, is direct-injected, meaning that fuel is injected under very high pressure directly into the combustion chamber, rather than into the intake. But, unlike other direct-injected engines, the Lexus engine retains a second set of injectors in the passe intake port location. One advantage of this costly approach: port injectors spray their fuel onto the backsides of the intake valves, preventing the carbon buildup that has all too often afflicted Audis.
New design with a new engine notwithstanding, many people will buy the Lexus NX instead of something else because they expect it will prove more reliable down the road. Based on our reliability data for other Toyota and Lexus models, I don't think they will be disappointed.
And the Lincoln MKC? It's still early, but the data we have so far does not bode well.

TrueDelta Reviews the Gas Mileage of the 2015 Lexus NX
||Even upscale manufacturers have been shifting from V6 engines to turbocharged fours for one big reason: the imperative to improve fuel economy. The Lincoln MKC's EcoBoost four isn't long on eco. With front-wheel drive (FWD), the 240-horsepower 2.0T engine scores 20 and 29 mpg in the EPA's city and highway tests, respectively. But these figures drop to 19/26 with all-wheel drive (AWD) and 18/26 with a 285-horsepower 2.3T engine option.
The Audi Q5 2.0T, with standard AWD, does a bit better: 20/28.
The 235-horsepower Lexus NX 200t does a bit better still, at least in city driving: 22/28 with FWD and 21/28 with AWD.
In my real-world suburban driving I could nudge the trip computer-reported average as high as 33 mpg. The upper 20s were easy to achieve. The trip computer averages in the MKC were typically about three mpg lower--even though the tested crossover did not have AWD.
The original Lexus RX 300, with a 220-horsepower 3.0-liter V6, wasn't nearly as efficient: 19/24 with FWD and 19/22 with AWD. One reason: its automatic had only four ratios. The NX's, like the Lincoln's has six. (The Audi's has eight.)
If fuel economy is a top priority, then Audi, BMW, and Mercedes-Benz offer diesels. The Mercedes-Benz GLK250, with EPA ratings of 24/33, much more easily topped 30 mpg in my suburban driving, and averaged 40 mpg on one run home from my son's school. The BMW X3 xdrive28d tested even better, 27/34.
To counter these diesels, Lexus also offers the NX in 300h form, the "h" for hybrid. I haven't driven the NX 300h, but the EPA rates it 35/31 with FWD and 33/30 with AWD.
