| 2013 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
I like the seats in this car a lot. The bolsters feel well placed and keep you from moving around too much when cornering with enthusiasm, and they're comfortable to sit in overall. see full Infiniti G review |

Roomy enough. Could be a little stiff or tight for some passengers. see full Infiniti G review |

I am inspired by the engine's performance. While behind the wheel I enjoy the power and sound of the tuned exhaust. see full Infiniti G review |
| 2013 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
With AWD, this car feels unstoppable. The first three gears are short and it moves through them smoothly with serious authority. The engine makes decent midrange power while making a nice bellow. Above 4500 it really goes. I was surprised into laughter on the way home when I thought, "I wonder what this thing can do," and gave it the beans on the entrance ramp to the highway. see full Infiniti G review |
| 2011 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic AWD |
Very fast, high torque throughout the range. You cannot shift as well as this 7 speed auto, so manual mode is all but irrelevant. see full Infiniti G review |

| 2013 | 4dr Sedan 328-horsepower 3.7L V6 7-speed shiftable automatic RWD |
The OEM tires are good enough, but I would pick a different all season radial the next time. Keep in mind, when replacing tires on this All-Wheel Drive, it is recommended to use the same size/diameter. see full Infiniti G review |
