2007 4dr Sedan, ext. 382-horsepower 5.5L V8
7-speed shiftable automatic RWD		 Since my driving is about 50-50 city and highway, I average about 20-21 mpg, using premium fuel. All highway is 29-30mpg and all city is 14-15mpg. see full Mercedes-Benz S-Class review
2007 0 While on long trips at 70-80mph I average 32mpg around town it never goes better than 24mpg. Easy on the pedal sure shows results but fully loaded the thing shifts like a two door sports. see full Mercedes-Benz S-Class review

TrueDelta Reviews the Real Gas Mileage of the Acura MDX

Acura MDX Real Gas Mileage: Pros
YearComment
2014 In addition to trimming the size and weight of the MDX, Acura also reduced the size of the V6 engine from 3.7 to 3.5 liters. Thanks to direct injection the new, smaller engine is nearly as powerful (290 vs. 300 horsepower), and is even a little punchier at low rpm. It can run on three cylinders to save fuel while cruising. The QX60's V6, also 3.5 liters, lacks direct injection and is only good for 265 horsepower. Even though the Infiniti's CVT (continuously variable transmission) can hold the engine at its power peak, this isn't enough to compensate for its power and weight disadvantages. The MDX is noticeably quicker, if still not thrillingly quick. (It can get to 60 mph in about seven seconds.) Then again, fuel economy appears to have been the priority. In the EPA's tests, the 2013 MDX rated 16 mpg city, 21 mpg highway. Infiniti, aiming to top these marks with the JX35 did so by two mpg (18/23). A redesigned CVT shared with the new Nissan Pathfinder bumps the QX60 to 19/25. The new MDX trails the Infiniti by one mpg in the city, but tops it on the highway with a 27 mpg rating--tying the new diesel BMW X5 and impressive for a gas-powered three-row crossover. In real-world suburban driving with an economy-minded right foot the trip computer reported averages from 21 to 23. With a feather-light foot and good luck with traffic lights, 25 can happen. Drive the MDX hard enough to enjoy the snarl that kicks in with the big VTEC cam lobes at 5,000 rpm, on the other hand, and mpg falls into the mid-teens. Highway driving confirmed the EPA estimate. see full Acura MDX review

2012 4dr SUV 300-horsepower 3.7L V6
6-speed shiftable automatic AWD		 Gas mileage is not good. The best I get is around 20 mpg, and use 91 octane as reccommended. I've tried mid-grade 89 octane with no noticable difference but for $1.00-$2.00 per tankful, I'm choosing to stick with what is reccommended. It would be nice to have a front wheel drive only version which would save on gas, but it's not offered. see full Acura MDX review
