The Lexus RX Hybrid’s electrically assisted V6 engine has grown from 3.3 to 3.5 liters. Along with more compact batteries and motors, the new engine gives the 450h even much better fuel economy than before. It also gets a new rear suspension and an interior that’s been redesigned and made more spacious. Overall, it’s an even more refined car than before, and one that might be worth it for Lexus loyalists
For 2010, Lexus has redesigned its RX Hybrid crossover and changed its moniker from 400h to 450h, marking the SUV’s second generation.
