| 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 |
