| 2008 | 4dr Sedan 306-horsepower 3.5L V6 5-speed shiftable automatic RWD |
I love the roominess of the rear seats. Most of my family are moderately large (6ft 220lbs). Two can fit in the back comfortably. see full Infiniti G review |

| 2009 | 2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic RWD |
Way to small to be of use with anything but children. see full Infiniti G review |

Tight on head room but to be expected for two door. see full Infiniti G review |
| 2009 | 2dr Coupe 330-horsepower 3.7L V6 6-speed manual RWD |
The bolstering is excessive in the lowest setting and the seat belt pulls too hard on my chest. The seat belt also digs into my neck. see full Infiniti G review |

| Year | Body/Powertrain | Comment |
| 2008 | 4dr SUV 280-horsepower 3.6L V6 6-speed shiftable automatic AWD |
The middle seat of all the SUVs we looked at, had the most room to move furthest forward or backward to allow far rear seat passengers most accommodation. see full Audi Q7 review |

Rear seat legroom is greater than other vehicles I evaluated in this category: Acura MDX, BMW X5, Mercedes ML; seats more plush; more cargo space. see full Audi Q7 review |
