It was bound to happen. With the hybrid-craze of late, it was only a matter of time before Lexus threw its hat into the fray. The all-new 2010 Lexus HS 250h five-seat hybrid sedan is Lexus' first dedicated hybrid, which means that there is no gas-only version. The HS 250h boasts leather seats, while the cabin uses bio-plastics ensuring the overall green effect. Speaking of the green-effect, the Lexus HS 250h receives an impressive 35 mpg in the city and 34 mpg on the highway. As you can see from these pictures taken at the 2009 LA Auto Show, the 250h is much more refined than the Toyota Prius and Honda Insight.
