Lexus launches the 2010 RX in L.A.

The RX line of SUVs has been Lexus' best-selling luxury utility vehicle since its launch in 1998, and the new generation takes the vehicle into a larger, more powerful realm, while at the same time adding new efficiency-enhancing measures in the hybrid model. The 450h, available in both AWD and FWD configurations, features two new technologies to boost fuel economy and reduce emissions.
