Business Notes TOYS

The hot new cars this fall feature aerodynamic design, quick acceleration and two interchangeable engines. They are also about six inches long and cost ten bucks.

Toymaker Hasbro Inc. is launching its new line of Record Breakers miniature racing cars with a $6 million advertising campaign highlighting their principal selling point: speed. The company says the battery-powered vehicles can go the equivalent of 500 m.p.h. in an adult-size automobile. Record Breakers are imported from Japan, where they are a national craze. While some analysts predict smaller U.S. sales, Mattel, Matchbox and other toy manufacturers are releasing their own superfast cars.
