General Motors, which signed a deal in 1999 to buy up to 90,000 engines and transmission annually from Honda, has agreed to take only 50,000 a year for use in its Saturn Vue sport utility vehicle, a GM official told Reuters on Tuesday.

"When we did the agreement ... we said it would be up to 90,000. We only require 50,000," GM spokeswoman Sherrie Childers-Arb told Reuters.

GM's five-year agreement to buy Honda 3.5 litre V6 ultra-low emission engines, which satisfy California vehicle emission regulations, and five-speed automatic transmissions for the 2004 Vue goes into effect next summer, Childers-Arb added in the conversation with Reuters.
