| Year | Body/Powertrain | Comment |
| 2009 | 4dr SUV 270-horsepower 3.5L V6 5-speed automatic AWD |
rear seating and space is grand. front cockpit is a bit short and chopped but acceptable. Front seats are not as comfortable as in our 2001 RX 300. The front seats are minimally acceptable. see full Lexus RX review |
