AFS Trinity Power Corporation is a private company currently exploring the option of licensing their XH™ system to major automakers or OEMs.
The drive train for a Plug-in Hybrid Electric Vehicle is expected to enable cars to achieve 250 MPG (equivalent) by combining a Lithium-ion battery pack with a bank of ultracapacitors. Fast Energy Storage™ enables high top speeds and rapid acceleration in electric-only mode (first 40 miles), as well as greater regenerative braking capability.
The prototypes are called XH-150s - "Extreme Hybrid" SUVs. AFS Trinity Power Corporation is the first company to use UL approved ultra-capacitors with a lithium-ion battery pack. The prototypes have been driving around the US since 2005.
There will be a production model available in 2-3 years. They are in discussions with auto makers and tier one suppliers who have an interest in this system.

Why do you call this a 150 MPG car if it is mostly electric?
:"Does it really get 150 miles per gallon? When discussing plug-in hybrid cars, mpg figures require deeper explanation. We have calculated gasoline mileage by using average American driving patterns estimated by the U.S. Department of Transportation and simulating the EPA combined urban/highway driving cycle of the host vehicle operating only with its conventional hybrid drive train. In 2003, the U.S. Department of Transportation reported that 78% of Americans drive less than 40 miles a day. On those days, drivers of Extreme Hybrids will need no gasoline at all -- even driving an SUV. Assuming that someone drives 40 miles a day, 6 days a week and 80 miles on one weekend day, total weekly distance traveled will be 320 miles. The first 280 miles are electric. The next 40 miles, on one weekend day, will use gas alone. Even if the car, while running only on gas on day 7, were to get only 20 mpg because the car were heavily laden and the driver has a “lead foot,” that would still mean the driver will use just a little more than two gallons of gasoline for the week. Although this translates into 160 MPG, we use a more conservative 150 MPG to take into account that mileage will vary depending on where and how a car is driven, but we are comfortable that 150 miles per gallon of gasoline is a good number for 78% of American drivers driving the way most Americans drive."

This 3D animation with voiceover demonstrates how the XH-150 works when operated in all-electric mode. By storing energy in Ultracapacitors and using them to deliver the fast energy required for acceleration, the XH-150 is able to accelerate quickly, without stressing the Lithium Ion Batteries or causing resistive heating to occur. 150 miles per gallon SUV.

Instead, they exhibit and demonstrate the fuel-efficient vehicles elsewhere in downtown LA during the show. (MarketWatch Nov. 7, 2008)
AFS TRINITY unveils 250 MILE PER GALLON Vehicle program at Girvan Meeting
Privately-held AFS Trinity Power Corporation unveiled a flywheel-based technology at a Girvan Institute meeting that the company expects will make it possible for the average American driver to achieve more than 250 miles per gallon fuel economy in a sedan and 200 miles per gallon in an SUV. According to AFS Trinity CEO Edward W. Furia, what the company calls the Extreme Hybrid™ drive train is expected to lower driving costs, cut emissions, and reduce American dependence on foreign oil. Related hybrid bus technology is expected to be deployed by AFS Trinity in a DOT demonstration project next year. The passenger car drive train is expected to begin development this year, be demonstrated in a prototype vehicle in two years and be ready for licensing to U.S. and foreign carmakers in three. (Feb 23, 2005)
The estimate for the XH™ drive train will add an additional $8,700 to the retail price of a vehicle without the drive train. In the case of the Saturn Vue, which is roughly $22,000, the XH™ version would cost about $31,000.
Estimated weekly gas costs, based on driving 320 miles per week, of $7.93 and weekly electricity cost of $7.56, for a total weekly fuel cost of $15.49. You can take a closer look at the numbers on their XH-150™ Performance Comparison chart.
Based on 300 complete battery discharges per year, the useful life of the batteries would be about 10 years or 3,000 cycles or 120,000 electric miles before replacment.
"Drivers should expect the Extreme Hybrid to pay for itself in five years or less depending on your driving habits and the future price of gasoline," AFS Trinity CEO Edward W. Furia said.
The XH-150 is not yet EPA-certified and will not be EPA-certified unless and until a production model is built and tested on a dynomometer. Therefore, all mileage numbers are necessarily AFS Trinity estimates of what EPA certified mileage will be after EPA certification.
AFS Trinity holds several patents for the XH system, including the special electronics and controls unit, which is essentially the brain of the Extreme Hybrid™ system.
Method and apparatus for power electronics and control of plug-in hybrid - Publication number: US 2007/0068714 A1 Inventor: Donald Arthur Bender
Abstract: A plug-in hybrid propulsion system includes a fast energy storage device that preserves battery life, where the energy storage elements of the hybrid drive train may be charged with externally supplied electricity as well as energy from the engine or regenerative braking. Electronic switches, passive electronics, an enclosure, controller circuitry, and/or control algorithms are used to manage the flow of power between a fuel powered engine, a battery, a fast energy storage system, traction motors, a charger, ancillary systems, an electrical distribution system, and/or a drive train.Drawing

AFS Trinity was formed on December 5, 2000, through the combination of two predecessor companies, American Flywheel Systems, Inc. (AFS), incorporated in 1991, and Trinity Flywheel Power (Trinity) which was incorporated in 1993. To the Company, AFS brought the world’s first and largest portfolio of advanced flywheel energy storage technology. At the same time, Trinity brought to the Company complementary short ride time flywheel power technology, for which it has the exclusive license from Lawrence Livermore National Laboratory, and a first-to-market composite flywheel product capable of addressing critical power quality and distributed generation applications for the digital economy.
