2007 2dr Convertible 215-horsepower 3.0L I6
6-speed shiftable automatic RWD		 Fuel economy is great. Getting 30 to 33 mpg on trips on 2 lane rural highways at 65 to 70 mph. see full BMW Z4 review
2006 2dr Convertible 215-horsepower 3.0L I6
6-speed manual RWD		 Around town I get about 23 mpg but on the open highway, get 30 to 32 mpg which is huge since the Z only uses premium grade gas. see full BMW Z4 review

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
2008 4dr Sedan 275-horsepower 3.5L V6
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
