Infiniti M Real Gas Mileage: Pros
YearBody/PowertrainComment
2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic AWD		 Fuel economy is abysmal around town. I guess that's the price you pay for going grocery shopping with over 300 HP. However, on the highway it's very possible to exceed the EPA mileage number. see full Infiniti M review
2006 4dr Sedan 335-horsepower 4.5L V8
5-speed shiftable automatic RWD		 V8 power--it's a gas guzzler and could've used an extra 1 or 2 speeds more since it revs so high at highway speeds. see full Infiniti M review
2006 4dr Sedan 335-horsepower 4.5L V8
5-speed shiftable automatic RWD		 78,000 miles primarily city driving and rarely use AC-16.9 mpg. 4.5 L V8 great power train with RWD-great fun to drive. see full Infiniti M review

2011 4dr Sedan 330-horsepower 3.7L V6
7-speed shiftable automatic RWD		 I get average about 22 MPG with 80% of highway driving, this is with baby footing of the car, in town and climbing the hill, the milage can drop to 18-19. see full Infiniti M review

2008 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic RWD		 needs a 6th gear, since there is too much revving in 5th gear while cruising. they put a 6th gear in the 2009 version see full Infiniti M review

5-speed shiftable automatic AWD		 Gas mileage stinks. see full Infiniti M review

2007 4dr Sedan 325-horsepower 4.5L V8
5-speed shiftable automatic RWD		 Averages about 18.5 mpg in mixed suburban/urban/freeway driving. Can get thirsty when you get on the gas, but duh... see full Infiniti M review
2007 4dr Sedan 275-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Large cars get poor milage. 18-20 mpg would like an option to trade some performance for added MPG. see full Infiniti M review
2006 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Often avergaed as low as 16mpg on a tank-full of gas. see full Infiniti M review
 

TrueDelta Reviews the Real Gas Mileage of the Lexus LS

Lexus LS Real Gas Mileage: Cons
YearComment
Nearly everyone except Toyota has been transitioning to boosted engines for fuel efficiency at least as much as for performance. While boosted engines swill gas at least as well as their unboosted equivalents when hustled, in typical driving they are more efficient. With EPA ratings of 16 mpg city, 23 mpg highway, the LS 460 nearly matches the Jaguar XJ AWD (16/24), but falls well short of the Audi A8 3.0T (18/28) and BMW 740Li xDrive (19/28). In the real world, the Lexus's fuel economy lags the others, including the Jaguar, to an even greater degree. In our suburban driving the LS 460's trip computer often reported averages between 15 and 16, vs. low 20s in the Jaguar. A light foot could nudge the LS's average to 18, but the XJ's to 25. On the highway the LS 460's trip computer reported averages of 24.7 and 23.3. The XJ's reported just over 30. see full Lexus LS review
