Plymouth Superbird – sports car, manufactured in 1970 by Plymouth. In fact, a highly modified “mixture” of Plymouth Road Runner and Dodge Charger Daytona.
1970 Plymouth Superbird review
Superbird was developed for the NASCAR racing series, to be exact, to replace the 1969 Dodge Charger Daytona. One of the main motivating factors create such a car was to lure a great pilot Richard Petty back to Plymouth, which will be a multiple winner on the Superbird in the future. The main rival of the cars was the Ford Torino Talladega, which in turn was a direct response to the GM’s Aero Mopar cars.
Compared to the prototype Dodge Charger Daytona, Superbird lines were worked out better, it causes the computer analysis and a lot of wind tunnel tests. Improved “nose” appeared retractable headlights, overall length increased to 19 inches (47 cm). The rear aerodynamic wing mounted on the additional rack, thereby increasing the already excellent downforce. For nearly thirty years, the formula for calculating the aerofoil kept a closely guarded secret, but in 1990, a retired engineer of Chrysler reveals the secret.
Rear-facing aerofoil, “scooping” the air flows through the holes in the wings to make cooling of the brakes easier. This technology was also borrowed from the Dodge.
“The Superbird” stickers were placed on the outer edges of the spoiler vertical stand, depicting “cartoon” character with a racing helmet, around which flaunted the inscription “Road Runner” and “Superbird”. A smaller version of the label is available on the driver’s side door.
Total was officially built 1920 Superbirds, but judging by the staff of the company publications, there were 2783.

Participation in NASCAR
In the fall of 1968, Richard Petty leaves Plymouth NASCAR Racing Team and goes to the Ford team. However, Ford team director Charlie Grey felt that you can’t keep such a talented pilot with money long hold. Less than two years later, Superbird “challenge” came out. And a month later, Richard Petty again goes to Plymouth Racing Team, winning eight races against the strongest opposition to the Ford NASCAR. In 1971, NASCAR imposes restrictions for the aerodynamic cars on the engine displacement amount that should not exceed 5.0 liters. Not wanting to put up with it, Plymouth Superbird was discontinued.
