Detroit News writer Henry Payne takes a look at the anticipated demise of the gasoline engine, and opines that maybe it's a bit early to write the obit:
At this year’s Society of Automotive Engineer’s convention in Detroit, one forum debated the question: “The Gasoline Engine Is Dead. Or Is It?” Siemens executive Michael Crane answered matter-of-factly: “For the foreseeable future, the gasoline engine will continue to dominate.” At present, Crane pointed out, gas powers 90-percent of autos on the planet with its fossil-fuel cousin, diesel, feeding most of the remainder. Only in Brazil and South Africa, where governments have dictated national alternative energy programs, has that supremacy been challenged.He then goes on to consider various alternative technologies.

Gasoline’s 100-year reign is no fluke: It offers high energy density per pound (125,000 BTU/gallon) at low production cost, with a manageable supply infrastructure. And gas engine technology is ever-advancing.
Today’s gas engines are near zero-emission vehicles. “If I mow my lawn for one hour,” says Crane, “I’d produce more emissions than if I drove a new car from New York to Los Angeles.” So clean is Ford’s Durotech engine, for example, that it meets California’s zero-emissions standard along with the celebrated Toyota Prius hybrid.
