Faced with tough new fuel economy rules and increased pressures to reduce CO2 emissions, automakers are offering an array of alternative propulsion systems that could one day replace today’s internal combustion engines.
There will be hybrids, flex-fuels, diesels, plug-ins and fuel cells on display, as well as enhanced gasoline engines, each offering its own argument for how to reduce dependence on oil and clean up the environment.

Cadillac Provoq
Cadillac Provoq
Odds of reaching production: high
This fuel cell concept is the latest example of GM’s new E-Flex propulsion system. It has a range of 300 miles, uses no gas and emits only water. The big hangup: Development of an affordable lithium-ion battery. But GM says it’s committed to displacing petroleum through new technologies. The Provoq also provides important clues to the future direction of Cadillac design. GM won't say when it might be produced, but is interested in producing a crossover with the same body style.
