Partnership for a New Generation of Vehicles






The 80 mpg diesel-hybrid General Motors Precept




The 72 mpg diesel-hybrid Ford Prodigy




The 72 mpg diesel-hybrid Chrysler ESX-3


The Partnership for a New Generation of Vehicles was a cooperative research program between the U.S. government and the three major domestic auto corporations, aimed at bringing extremely fuel-efficient (up to 80 mpg‑US (2.9 L/100 km; 96 mpg‑imp) vehicles to market by 2003.


The partnership, formed in 1993, involved eight federal agencies,[1] the national laboratories, universities, and the United States Council for Automotive Research (USCAR), which comprises DaimlerChrysler, Ford Motor Company and General Motors Corporation.


"Supercar" was the unofficial description for the R&D program.[2]


On track to achieving its objectives, the program was cancelled by the George W. Bush Administration in 2001 at the request of the automakers, with some of its aspects shifted to the much more distant FreedomCAR program.

Objectives


The main purpose of this program was to develop technologies to reduce the impact of cars and light trucks on the environment as well as decrease U.S. dependency on imported petroleum. It was to make working vehicles that can achieve up to triple the contemporary vehicle fuel efficiency as well as further minimizing emissions, but without sacrificing affordability, performance, or safety. The common term for these vehicles was "supercar" because of the technological advances. The goal of achieving the 80 mpg‑US (2.9 L/100 km; 96 mpg‑imp) target with a family-sized sedan included using new fuel sources, powerplants, aerodynamics, and lightweight materials.[3]


The program was established in 1993 to support the domestic U.S. automakers (GM, Ford, and Chrysler) develop prototypes of a safe, clean, affordable car the size of the Ford Taurus, but delivering three times the fuel efficiency.[2][4]



Results


The PNGV program "overcame many challenges and has forged a useful and productive partnership of industry and government participants",[5] "resulting in three concept cars that demonstrate the feasibility of a variety of new automotive technologies" with Diesel-electric transmission.[6]


The three domestic automakers, GM, Ford, and Chrysler, developed fully operational concept cars. They were full sized, five-passenger family cars that achieved at least 72 mpg‑US (3.3 L/100 km; 86 mpg‑imp).[7]


General Motors developed the 80 mpg Precept, Ford designed the 72 mpg Prodigy, and Chrysler built the 72 mpg ESX-3. They featured aerodynamic, lightweight aluminum or thermoplastic construction and were hybrid powered using 3- or 4-cylinder diesel engines and NiMH/lithium batteries.[7]


Researchers for the PNGV identified a number of ways to reach 80 mpg including reducing vehicle weight, increasing engine efficiency, combining gasoline engines and electric motors in hybrid vehicles, implementing regenerative braking, and switching to high efficiency fuel cell powerplants. Specific new technology breakthroughs achieved under the program included:[8]



  • Development of carbon foam with extremely high heat conductivity (2000 R&D 100 Award)

  • Near frictionless carbon coating, many times slicker than Teflon (1998 R&D 100 Award)

  • Oxygen-rich air supplier for clean diesel technology (1999 R&D 100 Award)

  • Development of a compact microchannel fuel vaporizer to convert gasoline to hydrogen for fuel cells (1999 R&D 100 Award)

  • Development of aftertreatment devices to remove nitrogen oxides from diesel exhaust with efficiencies greater than 90 percent, when used with diesel fuel containing 3 ppm of sulfur

  • Improvement of the overall efficiency and power-to-weight ratios of power electronics to within 25 percent of targets, while reducing cost by 86 percent to $10/kW since 1995

  • Reduction in cost of lightweight aluminum, magnesium, and glass-fiber-reinforced polymer components to less than 50 percent the cost of steel

  • Reduction in the costs of fuel cells from $10,000/kW in 1994 to $300/kW in 2000

  • Substantial weight reduction to within 5 to 10 percent of the vehicle weight reduction goal



Criticisms


Ralph Nader called PNGV "an effort to coordinate the transfer of property rights for federally funded research and development to the automotive industry".[9]


The program was also criticized by some groups for a focus on diesel solutions, a fuel that is seen by some as having inherently high air pollutant emissions.[10]


Elizabeth Kolbert, a staff writer at The New Yorker, described that renewable energy is the main problem, and that "If someone, somewhere, comes up with a source of power that is safe, inexpensive, and for all intents and purposes inexhaustible, then we, the Chinese, the Indians, and everyone else on the planet can keep on truckin'. Barring that, the car of the future may turn out to be no car at all."[11]

AM broadcasting

"AM Radio" redirects here. For the song by Everclear, see AM Radio (song). For the American musical group, see AM Radio (band). AM broadcasting is a radio broadcasting technology, which employs amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions were begun in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have a...
