TrueDelta Reviews the Real Gas Mileage of the Lexus NX

Lexus NX Real Gas Mileage: Pros
Year	Comment
2015	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. see full Lexus NX review

2010	4dr SUV 262-horsepower 3.5L V6 6-speed automatic FWD	I am currently averaging 20 MPG overall with heavy highway use. For the size of vehicle I think that is rather reasonable. see full Ford Flex review
2010	4dr SUV 262-horsepower 3.5L V6 6-speed automatic FWD	1000 miles of ownership so far, 21-22 mpg in light suburb and highway driving, 24-25 mpg on 500 mile trip (fuel economy measured by calculating miles driven divided by gallons of fuel purchased). see full Ford Flex review
2009	4dr SUV 262-horsepower 3.5L V6 6-speed automatic FWD	Only driven around town, mileage 16.6, have never had it on the open road. see full Ford Flex review
2009	4dr SUV 262-horsepower 3.5L V6 6-speed automatic FWD	Very good for a 4500 lb vehicle. see full Ford Flex review
