Mercedes-Benz’s marketing plan for the new S-class plug-in hybrid aims to show prospective buyers that going green doesn’t mean slowing down or paying more. Mercedes’ message emphasizes that the S 500 Plug-In Hybrid sprints from 0-100kph in 5.2 seconds while costing the same —  €108,945 in Germany — as the S 500 with a V-8 gasoline engine that consumes more than three times as much fuel.
