The S-class is a tech-lover's dream, loaded with seats that massage, radar that keeps set distances from other cars, mirrors that warn about cars to either side, and a speedometer that turns into a night vision camera. We were in seventh heaven riding around on its plush seats, listening to music from an iPod over its sweet-sounding Harman Kardan audio system.
And while previous S-classes left us with a little green guilt, or at least range anxiety, as the engine gulped down the gas, the S400 Hybrid has a more reasonable appetite. It is far from Prius territory, but it tops 20 mpg.
