IN BRIEF : GM Offers New Line of Minivans

General Motors Corp. executives today rolled out a new line of multipurpose passenger vehicles for 1990 and for the first time included an Oldsmobile minivan in its stable.

William W. Lane, Oldsmobile general manager, said the utility vehicle will give Olds the chance to capitalize on the growth in the minivan market. The trend was started and is dominated by Chrysler Corp.

Chevrolet General Manager Bob Burger said Chevrolet’s Lumina, Oldsmobile’s Silhouette and the Pontiac Transport SE will be built at the GM plant in Tarrytown, N.Y.

Production of the vehicles is expected to reach 100,000 during the 1990 model year, rising to 225,000 in later years, Burger said.

Lane said he expects the minivan market to sell 1 million vehicles a year in the 1990s, compared with 750,000 sold annually now.
