TrueDelta Reviews the Real Gas Mileage of the BMW X3

BMW X3 Real Gas Mileage: Pros
YearComment
2013 While the boosted four has a clear performance advantage, the swap was motivated primarily by the push for better fuel economy. EPA ratings are 21 mpg city, 28 highway, vs. the 2012 six's 19/25. An Audi Q5 comes close, 20/28, but with 211 horsepower isn't as strong. Despite weighing about 400 pounds less than the X3's 4,112, a Ford Escape with a similarly spec'd engine does no better. A Mercedes GLK350? 19/24. The Volvo is even worse. Compared to cars, the X3 doesn't fare as well. The roomier, nearly as heavy 528i rates 22/33. The crossover's larger frontal area and higher ground clearance take their toll as speed climbs. In our real-world sub-freezing suburban driving, the trip computer usually reported about 21 once the engine was warmed up, matching the EPA rating and quite good for a powerful, two-ton, all-wheel-drive vehicle. Engage an aggressive Eco Pro mode for a Prius-like throttle response and ultra-low rpm shifts, and mid-20s are easily achievable while high 20s are possible. I even observed 32 over one short trip where the lights were in my favor. But the cars behind you won't be happy. Conversely, enjoy the turbo at every opportunity and fuel economy will fall into the teens. A defeatable standard auto start/stop system operates a little more smoothly than in last year's 3-Series, but not as smoothly as it ought to. see full BMW X3 review

City driving fuel economy is not bad for an SUV. I average around 16MPG battling heavy traffic and my need for “enjoying using the accelerator”. Highway mileage is not so great. Cruising at 70-80MPH returns around 22MPG. see full BMW X3 review
 

TrueDelta Reviews the Real Gas Mileage of the Lexus RX

Lexus RX Real Gas Mileage: Pros
YearComment
2013 The new transmission doesn't affect EPA city mpg, which remains a competitive if not outstanding 18. Highway mpg receives a bump from 24 to 26, putting it two to three mpg over most competitors. At a steady 75 mph, the F Sport engine is spinning 1,950 rpm, vs. 2,300 in the regular RX with a six-speed automatic. In suburban driving with the engine warmed up the trip computer typically reported 22 mpg. A very light foot bumped this by three mpg, while a heavy one sunk it by about the same. Buyers who put a high priority on fuel economy will prefer the RX 400h hybrid. It earns EPA ratings of 32 city, 28 highway, and is even a little quicker than the RX 350. Real-world suburban mpg appears to be about 29. see full Lexus RX review
