Lexus confirmed today that the 2010 RX will make its world debut next month at the Los Angeles Auto Show. The design of the 2010 RX will not stray too far from the current design, which didn’t stray too far from the original 1997 design. The updates to look of the RX will likely be inspired by the Lexus LF-Xh hybrid Concept revealed last year at the Tokyo Show (using Lexus’ "L-finesse" style.)
Not much is known about the technical details, except that the next generation will continue to receive a hybrid version. When we know more, you’ll know more.
