Frankfurt Motor Show. The plug-in series hybrid has a 136-horsepower electric motor with a 62-mile range, and a 67-horsepower, 1.0-liter three cylinder turbocharged gas engine for range-extending capabilities up to 373 miles. At low speeds, the petrol engine charges the lithium-ion batteries. When going faster, it acts on the car's front wheels, while the electric engine also chugs along -- very much like the Chevy Volt. Mercedes promises zero to 62MPH in 11 seconds and top speeds of 93MPH in both battery-only and range-extending modes. No word yet on when this dream ride will be available for family carpools, but eager June Cleavers can check out the photo gallery and full PR after the break.
Update: We've added a gallery from Frankfurt!
