Mattel Intellivision Game: U S Ski Team Skiing (1980 Mattel) 

In U.S. Ski Group Skiing, players race down the slope, trying not to trees and bounce head honchos in their way. The game elements are both slalom and downhill courses. 1 player might attempt to beat the odds, or 2 to 6 players can substitute turns and competition to see who gets the quickest time, and each race has 3 warms.
Both downhill and slalom courses have 15 different incline grade settings to influence speed increase. There are also four different settings for the overall speed of the game.
