| Year | Body/Powertrain | Comment |
| 2013 | 4dr SUV 325-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Could be better by today's standards |
| 2010 | 4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD |
love the V6 power but the EPA MPG is worrisome |
| 2009 | 4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD |
17MPG in the city is a little disappointing for a vehicle with such finesse and reputation. I would guess Infiniti would cater to the masses with styling, performance and a little more economy. Not asking for miracles but I'm sure they could squeeze out 3 or 4 more MPG with the same 3.5L V6 |
| 2008 | 4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD |
Slightly low if driving mostly city. |
| 2008 | 4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic RWD |
Uses premium fuel. |
