150 MPG (Equivalent): XH-150 and XH250 Hybrids
At the Detroit 2008 Car show… Details over at Autobloggreen…
AFS Trinity Power Corporation is displaying a new hybrid SUV (actually a converted Saturn Vue) that gets more than 150 mpge thanks to something AFS calls the Extreme Hybrid (XH). The SUV recently achieved “more than 150 miles per gallon of gasoline based on the EPA Combined Urban/Highway Driving Cycle with 6 days per week of 40 miles per day in all electric mode and one day at 100 miles with assistance of the gas engine.” The test reportedly returned mpge numbers of around 170, but AFS wants to use 150 so as not to leave people disappointed if they drive more aggressively or under different circumstances than the test was run in.

GM’s new electric car project - the Volt
GM had a successful electric car push a few years ago, but abandoned it after what appeared to be successful public trials, causing some to theorize that the car was “killed” for other-than-technical reasons. (See “Who Killed the Electric Car?” for more background.)
Today, GM announced that they are re-entering the electric car market with a novel electric design which uses the latest battery technology coupled with a small on-board recharging engine which is powered by gasoline.
This system of battery-drive with combustion engine re-charging is very similar to proven naval propulsion designs used most notibly in diesel-electric submarines from World War II thru present day. In similar systems, electric battery banks power electric motors while underwater with diesel engines recharging as needed while on the surface or at snorkle depth.
…The push to develop environmentally friendly cars is also an attempt by GM to distance itself from its close association with gas-guzzling sport utility vehicles, a reputation executives say has hampered its sales in some markets.
The Volt’s combustion engine is designed only as a supplement to keep its batteries charged, an innovation GM executives hope will help the automaker jump ahead of Toyota Motor Corp. (7203.T), which now dominates the hybrid market…

Plug-In Hybrids = 100+ MPG
A Plug-In Hybrid (PHEV) is essentially a regular hybrid with an extension cord. You can fill it up at the gas station, and you can plug it in to any 120-volt outlet. It’s like having a second fuel tank that you always use first — only you fill up at home, from a regular outlet, at an equivalent cost of under $1/gallon…
…PHEVs are meant to plug-in at night. In many areas of the country, overnight power is available at a lower cost. As PHEVs start to enter the marketplace, we’ll see increasing support from electric utilities, as they’ll offer reduced nighttime rates to incentivize off-peak charging. In some areas where wind and hydropower is wasted at night, the rate can be as low as 2-3 cents per kWh. That’s 20-25 cents a gallon…
…The nationwide electrical grid is only 3% petroleum-fueled, whereas transportation is almost completely powered by oil — 60% of which comes from foreign sources (and growing). Adoption of plug-in hybrids will transfer the overwhelming majority of our miles driven to nearly oil-free electricity. If all vehicles were plug-in hybrids we would cut our oil needs by 55%, nearly enough to eliminate foreign sources altogether.
The winning combination from an environmental and national-security perspective is the flexible-fuel PHEV — one that runs on biofuels, cellulosic ethanol, methanol, or alternative liquid fuel in place of gasoline. This will reduce the transportation sector’s use of oil to almost zero — and cut the United States’ annual oil needs by 2/3.
