Swiss Researchers Make an 80-mpg Hybrid

If electric vehicles don’t take off, maybe we can achieve fuel economy targets with cars that combine a little bit of everything.

Researchers at the Swiss Federal Institute of Technology in Zurich have developed an ultra-efficient new engine that runs on a combination of natural gas and diesel. When combined with a battery and electric motor to make a hybrid vehicle, it could allow a car to get the equivalent of 80 miles per gallon, the researchers say. That’s far better than the 50 miles per gallon you can expect from the most efficient existing hybrids such as the Toyota Prius. The only catch would be finding both natural gas and diesel for refueling.

Does anyone still have any issues around of the old "Science and Mechanics" magazine? Seems to me that I remember back in the late '70s (early '80s?) a couple of guys in Florida put a marine diesel in a car and got 84 mpg at 35 mph. What they did was to turbocharge the engine with several turbochargers in series, thereby bringing up the compression pressure to such a high point that the ensuing burn put out tremendously more energy for the same amount of fuel.

They asked Ford for 10,000 Maverick cars without engines, so that they could put their engines into them, and sell them that way. But the EPA shut them down for producing too much nitrous oxide in the exhaust... or something like that.
