Michigan researchers have built a prototype of a new auto motor that does away with pistons, crankshafts and valves, replacing the old internal combustion engine with a disc-shaped shock wave generator. It could slash the weight of hybrid cars and reduce auto emissions by 90 percent.
Split cycle engines—engines that split the functions of a normal four-cycle piston into two separate but adjacent and complementary pistons—have never been able to match the efficiency and overall function of traditional internal combustion engines, but a new design could change all that. By tweaking the standard split-cycle design with new features like a compressed air tank that captures wasted energy from the system, the Scuderi Group claim not only to have matched the efficiency of the standard four-cycle engine, but to have far surpassed it.
Take an accelerometer, add a microcontroller and display, and watch the dollars fly out of your carburetor

Pain at the pump continues to reach new levels of misery every day. While most of us can’t afford to trade our current gas guzzler for a more fuel economical model, it would be nice to adopt some new driving skills that will translate into greater fuel economy. But where do you start? How do you know if your current jitney is a fuel sipper or a gas guzzler?
With gas prices going through the roof, yesterday's jalopy could be today's blue-chip used ride

A rust-dappled Hyundai for $3,000, a clapped-out Geo Metro for $5,000, and a censurable Ford Festiva for six grand? Welcome to upside-down world. The rising price of dinosaur champagne has already decimated the large-SUV business, and now the realities of gasoline economics are elevating what was once the lowliest segment of the used-car market into Croesus' territory.
More people are buying hybrid cars, but the greener vehicles are still a relative rarity on the road

In 2007, registrations of new hybrid vehicles jumped by 38 percent to 350,289 vehicles, according to a new report from R.L. Polk & Company. Gee, I wonder why? Maybe it's got something to do with rising prices at the pump, or climate change. Or maybe there's something bigger at play.
The Honda Civic will be the first to get a hybrid powertrain.

Mainstream sedans are ready for their gas-electric acid test. When it hits dealerships this spring, the Honda Civic will be the first to get a hybrid powertrain.
The battery package in the Civic is 42 percent smaller than that of its hybrid sibling, the Insight, which means more room inside.
In our tests near Palm Springs, California, the 1.3-liter four-cylinder powered the car to 60 in a respectable 11 seconds. Expect fuel economy in the high 40s, 10 mpg better than ordinary Civics.
