Spacious and comfortable seats see full Infiniti G review |
| 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 Infiniti G Seat Room and Comfort: Cons | ||
| Year | Body/Powertrain | Comment |
| 2010 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD |
Smaller than the Maxima. Third person would be uncomfortable, less knee room. The plastic trough behind the front seat is too low. see full Infiniti G review |
| 2010 | 2dr Hardtop conv. 325-horsepower 3.7L V6 7-speed shiftable automatic RWD |
The rear seat is basically a storage area. No one can sit back there! But its really no different than the rear of any convertible. (like my Mercedes Benz CLK350) see full Infiniti G review |
| 2010 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Seats in back are cramped. Once the kids hit teenage years they are not going to be happy back there for long rides. see full Infiniti G review |
| 2010 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD |
Seems smaller than the G35, no rear reclining seats anymore and the headrests stick up a bit more than the old car. 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 |
| 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 |
| 2009 | 2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Tight on head room but to be expected for two door. see full Infiniti G review |

very fast, but then again, upgrading from a 1999 civic....anything is fast. see full Infiniti G review |
| 2010 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Smooth as silk power and loads of it--more than anyone really needs for daily driving and more than enough to always bring a smile to your face. see full Infiniti G review |
| 2010 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
I compared the G37x to the BMW 325 xi. I chose the G37 x because it had better throttle lag, and more precise road feel, although a somewhat rougher ride. I also believe that the repair and maintenance costs of the Infinity may be less than the BMW for comparable repairs or maintenance items. see full Infiniti G review |
| 2009 | 2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic RWD |
Wide power band in the mid to high range, always feels like the car wants to go faster and has more to give at any speed. Great exhaust note, sometimes the thrill of accelerating is more about the sound than anything else. see full Infiniti G review |
| 2009 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Instant off the line acceleration is fun when you have room to use it. see full Infiniti G review |

I don't know if I am starting to turn into one of those old guys (I'm only 22) or not but it amazes me every time I step on the pedal that there are 328 horses ready to giddy up, especially when one of the cars I was looking at was a V8 with 350. This seems more logical. see full Infiniti G review |
| 2009 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD |
I love the power of the engine and the way it accelerates. see full Infiniti G review |
| 2009 | 2dr Coupe 330-horsepower 3.7L V6 7-speed shiftable automatic RWD |
The car is really powerful and fast for a performance luxury car. The engine is a "Sports Car" engine, with a very distinctive exhaust note that is exquisite. see full Infiniti G review |
