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

2013	4dr SUV turbocharged 240hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Upper 20's on highway and mid-20's in suburbia from a vehicle that weighs 5K lbs. see full Mercedes-Benz M-Class review
2009	4dr SUV turbocharged 210hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	Other luxury cars/SUVs require premium gas. Diesel could be same or even cheaper than regular gas and with immense torque and a somewhat light foot I get almost 25Mpg see full Mercedes-Benz M-Class review
2007	4dr SUV turbocharged 215hp 3.0L V6 Diesel 7-speed shiftable automatic AWD	5000 lbs vehicle. Gets 32 mpg on highway up to 75 mph, faster than that mpg drops. 23 to 24 mpg around town see full Mercedes-Benz M-Class review

Mercedes-Benz M-Class Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2007	4dr SUV 302-horsepower 5.0L V8 7-speed shiftable automatic AWD	Have a V8, so I should have expected, but mpg is averaging about 16 around town. With the current gas prices, I dread going to the pump. $90 to fill up the huge tank. see full Mercedes-Benz M-Class review
