Fuel efficiency has been a hot topic for years with hybrids becoming commonplace, but Mercedes-Benz was already looking in that direction way back in 1981. They debuted the Auto 2000 at the Frankfurt Motor Show as a car that used aerodynamics and mechanical advancements to be as fuel efficient as possible.
According to Classic Driver, the first had a V8 gas engine with a cylinder shutdown system where four cylinders idled under partial engine loads. This is technology that has only recently made its way into modern cars. The next version had a 3.3-liter 6-cylinder diesel engine with twin turbochargers. It was capable of 31.3 mpg at 75 mph. Those are some impressive numbers for 1981.
