GM Series Hybrid

"GM to unveil electric car prototype
The vehicle would use an onboard engine to produce power to extend battery range.
By John O'Dell, Times Staff Writer
November 9, 2006
General Motors Corp., vilified by environmentalists for killing the electric car, is hoping to bring one back.
But the new electric won't be an emissions-free vehicle, unlike the initial GM electric, the EV1.
The new car, to be unveiled as a prototype early next year, would use an onboard internal-combustion engine as a generator to produce electricity to extend the range of the vehicle's rechargeable batteries.
The idea was greeted enthusiastically by Chris Paine, director of "Who Killed the Electric Car?" The recent documentary took GM to task for creating and then abandoning the first production electric vehicle since the early 1900s.
"Bring it on," he said, noting that he has never doubted GM's ability to produce an environmentally friendly electric vehicle but has criticized its commitment to marketing one. . . ."

Re: GM Series Hybrid
GM showed a series-hybrid (based on the EV1) back in 1999. Here is what wiki has to say about it:
"The series hybrid prototype had a gas turbine engine APU placed in the trunk. A single-stage, single-shaft, recuperated gas turbine unit with a high-speed permanent-magnet AC generator was provided by Williams International; it weighed 220 lb (99.8 kg), measured 20 inches (50.8 cm) in diameter by 22 inches (55.9 cm) long and was running between 100,000 and 140,000 rpm. The turbine could run on multiple fuels, from reformulated gasoline to compressed natural gas. The APU started automatically when the battery charge dropped below 40% and delivered 40 kW of electrical power, enough to achieve speeds up to 80 mph (128.8 km/h) and to return the car's 44 NiMH cells to a 50% charge level.
A fuel tank capacity of 6.5 gallons (24.6 l) and fuel economy of 60 to 100 mpg (3.9 to 2.4 L/100 km) in hybrid mode, depending on the driving conditions, allowed for a highway range of more than 390 miles (627.6 km). The car accelerated to 0-60 mph in 9 seconds."
