MORE LEXUS HS 250h @ INSIDELINE.COM: www.edmunds.com We're sensing an eerie state of calm from the Lexus officials at the introduction of the 2010 Lexus HS 250h in Newport Beach, California. It's the kind of calm you experience at a poker table, when you're waiting for the other guy to finally lay down his cards. Then it happens. An executive cheerily admits that he hasn't a clue about how well this newest member of the Lexus family will be received by the marketplace. Fuel prices are too volatile, he says. In this line of work, a response like this would normally be intercepted by the brain in its formative state and its utterance prevented. So either the Lexus brass is speaking the truth or they're simply being coy. We would find out later that it's some combination of the two.
