Plymouth Superbird


Plymouth Superbird

Plymouth built the 1970 Superbird to win NASCAR. Ford had been dominating the races in the 1960s with their Talladegas and even the 1969 Dodge Daytona couldn't defeat them. So, in 1970 the 'Bird came out with better aerodynamics and enough downforce for 200mph (320km/h). Under the hood the by-then legendary 426ci (6.9-liter) Hemi was fitted. This engine was so-called because of its hemispherical combustion chambers, which meant it could use bigger valves and thus let more fuel in. The Superbird was so fast that it won 21 races and the championship in its first season but NASCAR rules to keep competition even imposed engine restrictions on cars with rear wings, and so it was banned. Plymouth had trouble selling the street versions because of its looks, so many had (he nose cones and rear spoilers stripped to be sold as standard Dodge Chargers.
