GENERAL MOTORS A BIG WINNER IN POPULAR SCIENCE'S 'BEST OF WHAT'S NEW'

GENERAL MOTORS A BIG WINNER IN POPULAR SCIENCE'S 'BEST OF WHAT'S NEW'
 NEW YORK, Nov. 10 /PRNewswire/ -- General Motors (NYSE: GM) and its divisions received five of the 11 awards in the "Auto Technology" category of Popular Science magazine's "Best of What's New" program for 1992. GM Technical Staff's 100mpg Ultralite concept vehicle received a Grand Award as the best in the category in which GM took more awards than any other manufacturer.
 In addition to the Ultralite, other GM recipients included two awards to the Cadillac Motor Car Division for its Northstar engine and road-sensing suspension and single awards to Oldsmobile for the power sliding door on the Silhouette van and GM Hughes for its development of an inductive charging system for electric vehicles.
 The annual selection of the year's 100 top products, technologies and scientific achievements by the editors of Popular Science was announced by the magazine in its December issue.
 "This recognition by Popular Science is a tribute to the technical strength of GM and its people," said Arvin F. Mueller, GM vice president and general manager of Engineering and Design Operations.
 "This wide range of awards also recognizes the breadth of our technology, from the experimental Ultralite designed for 100mpg performance and incorporating 100 advanced design features, to world- class production engines and suspensions and electrical systems," said Mueller. "We're particularly pleased to have GM Hughes Electronics receive recognition for its efforts to make GM's electric vehicle program a success, a clear sign of technical synergy between the two organizations."
 A brief description of each of the award-winning GM technologies selected for recognition in the Popular Science "Best of What's New" program follows:
 -- GM Ultralite -- GM won a Grand Award for the Ultralite, a working prototype of a high-mileage, four-door passenger car that debuted during 1992. While not intended for actual production, the Ultralite is an engineering test bed to explore advanced materials and efficient systems. At just 1,400 pounds, the Ultralite can achieve 100 miles per gallon at a 50 miles per hour cruising speed powered by an experimental 173-pound three-cylinder two-stroke engine. Its experimental high- strength, lightweight carbon fiber body is similar to material used in the most advanced jet fighters. The Ultralite was a joint project between GM's Design Staff and Advanced Engineering Staff and was completed in about 100 days.
 -- Cadillac Northstar Engine -- The transverse-mounted 32-valve 4.6-liter Northstar V8 engine, first introduced on the 1993 Cadillac Allante, is the world's most powerful front-wheel-drive engine and reinforces Cadillac's pre-eminent position in luxury car technology. The Northstar engine, a joint Cadillac and GM Powertrain effort, develops 295 bhp at 6,000 rpm and 290 lbs-ft of torque at 4,400 rpm. The Northstar V8 propels the Allante from zero to 60 mph in under 7.0 seconds. In addition to the Allante, the Northstar V8 is standard for 1993 in the Eldorado Touring Coupe and the Seville Touring Sedan (STS).
 -- Cadillac Road-Sensing Suspension -- Standard on the 1993 Allante, Eldorado Touring and Sport Coupes and STS, Cadillac's Road-Sensing Suspension system provides the seemingly conflicting virtues of smooth, comfortable ride and taut, stable handling over the widest possible range of operating conditions and compromises. The breakthrough technology of this system challenges active suspension systems in performance with a lighter, more efficient and much lower-cost package -- without giving up the comfort demanded by Cadillac customers.
 -- Oldsmobile Silhouette Power Sliding Door -- The power-operated sliding door that opens or closes at the touch of a button is a new-for-'93 innovation on the Oldsmobile minivan. Switches are at two convenient locations -- on the overhead Console for the driver and front-seat passenger and on the B-pillar for middle-row passengers. In addition, both the inside and outside side door handles and the keyless entry fob also activate the power door function.
 -- Hughes Aircraft Inductive Charging System -- Hughes Aircraft of GM Hughes Electronics developed an electric vehicle charging system that is safe to use in any weather, has no direct electrical connections and promises reduced cost and mass on the vehicle. The system utilizes induction to safely transfer electricity from one point to another. A magnetic field replaces the common metal plug/socket most people are accustomed to using when they plug in an appliance. In its place is a five-inch, round plastic-covered paddle that completely encases an electronic "coil." The electric vehicle is equipped with a charging port that also incorporates electric coils. When the paddle is inserted into the charging port, the magnetic fields form an isolation transformer to complete the circuit. The incoming AC power is then converted to DC and stored in the vehicle's batteries. This inductive system has been baselined on GM's Impact electric vehicle which is now undergoing development. Hughes Aircraft is offering this system to other electric vehicle manufacturers as a potential universal standard.
