NASCAR
The third generation Chevelle was an extensively used body style in NASCAR competition from 1973 to 1977. The Chevelle Laguna in particular was extremely successful allowing Cale Yarborough to win 34 races and earn the first two of three consecutive Winston Cup championships. Considered a limited edition model by NASCAR, the Laguna S-3 was ineligible for competition following the 1977 season.
Motor Trend said in 1973: "While neither Chevrolet or Pontiac are back in racing, the new crop intermediates out of GM's styling studios are curiously aerodynamic. They are also curiously competing on the NASCAR circuit tracks, and selling as fast as they can be hauled to the dealerships."
