DETROIT — General Motors said that its April sales rose 6.4 percent, helped by big gains in its four remaining brands.

TOP SELLER: Chevrolet Silverado. GM sold 29,618 during the month, up 12 percent from a year ago.

HOT MODELS: Chevrolet Equinox. April sales of 11,987 were a 190 percent improvement over last year.
