HybridCars.com has a terrific write up on the brand new Mercedes Benz S400 Hybrid rolling into showrooms this summer. Take a read:

The Mercedes Benz S400 Hybrid is the world’s first mass produced car with a lithium ion battery. It’s the first Mercedes with a hybrid drive. And, with a price tag likely to approach or exceed $100,000, it’s going to be an ultra-niche vehicle. The S400 Hybrid will arrive in US showrooms beginning in August 2009. The S400 shares the look of the S-Class. Signs of its recent facelift include a more aero grille, revised LED lighting at the front and back, and new mirrors, tailpipes, and wheels. The Mercedes Benz S400 hybrid is a luxurious, fuel-efficient saloon with lots of driving appeal. With its steep purchase price, it’s obviously not for everyone—but it is one more option for uncompromising affluent buyers seeking a slightly greener ride. – from Hybrid Cars
