We’ve known since the LA Auto Show that the 2010 Lexus RX would be returning better gas mileage, but a press release issued yesterday gave us the exact EPA figures, which I’ve compared with last year’s numbers (broken down as city/highway/combined):
| Model | 2010 | 2009 | Change |
| RX 350 FWD | 18/25/21 | 18/23/20 | +0/2/1 |
| RX 350 AWD | 18/24/20 | 17/22/19 | +1/2/1 |
| RX 450h FWD | 28/27/28 | 27/24/25 | +1/3/3 |
| RX 450h AWD | 28/26/27 | 26/24/25 | +2/2/2 |
It looks like most of the gains were in the AWD models, but numbers are up across the board. This is especially impressive considering the additional weight the 2010 models are carrying.
