2010 Lexus RX 450h

Lexus introduced the world to the idea of a luxury crossover with the original RX, then with the second generation, introduced the first luxury hybrid with the 2005 RX 400h. Upping one’s own ante is never easy, but at the 2008 L.A. Auto Show, Lexus showed it’s willing to try with the all-new 2010 Lexus RX 450h. With more power from its 3.5-liter Atkinson-cycle V-6, but better fuel economy, it’s definitely headed in the right direction. With a smaller, more powerful electric inverter, it’s even closer. The RX also uses other tricks, like a new exhaust gas recirculation system to help reduce emissions and improve fuel economy further. Lexus promises economy in the range of a four-cylinder mid-size sedan; we’ll have to wait until sometime in the middle of next year to put that to the test.
