According to reports, the 4-seater could have as much as a four-hour flight time. If you are thinking that doesn't seem feasible given the energy density of today's batteries, you're probably right. Not mentioned in the press release is the fact this first flyer will actually be a plug-in hybrid outfitted with an auxiliary power unit running on jet fuel.
For its part, Bye Energy has been working on putting together the electric aero-drivetrain since 2008. Though its not known which specific components will go into this POC, video from earlier this year showed them discussing an approach that would use a UQM 125 motor as well as thin-film solar cells on top of the wings to increase range. Hit the jump to check out that footage as well as a news report about the announcement and the official press release.

Cessna and Bye Energy Developing Electric-Powered Proof-of-Concept Skyhawk
OSHKOSH, Wis., July 26, 2010 - Cessna Aircraft Company, a Textron Inc. (NYSE: TXT) company, today announced that it is collaborating with Bye Energy, Inc., an integrator of clean, alternative energy technologies for business and general aviation aircraft, to design and develop an electric propulsion system for a Cessna 172 proof-of-concept (POC) aircraft.
Cessna's Chairman, President and CEO Jack J. Pelton said, "As we look at the landscape of alternative fuels for general aviation aircraft, the electric power plant offers significant benefits, but there are significant challenges to get there. We believe Bye Energy has gotten off to a good start in understanding those challenges and how to overcome them."
George Bye, CEO of Bye Energy Inc., thanked Cessna for its collaboration. "We are honored to work with Cessna in accomplishing the proof of concept endeavor. Cessna's support of the electric and electric-hybrid program is vital to moving general aviation into the future," he said.
Representatives from Bye Energy will be at the Cessna exhibit during EAA's AirVenture on Thursday, July 29, 11 a.m. to 3 p.m., for one-on-one interviews.
First flight of the electric-powered Cessna 172 Skyhawk POC is expected to take place by yearend.
