Plymouth Superbird generations
1 generation (1970–1970)
The first and only generation of the Plymouth Superbird was produced in 1970 as a coupe hardtop. Power ranges from 390 to 425 hp, always with rear-wheel drive, and both Automatic and Manual gearboxes were offered across its 4 modifications. Engine displacement spans two units: a 6900 cc engine in the 425 hp versions and a 7210 cc engine in the 390 hp version. Acceleration figures are close across the range: the 425 hp cars reach 100 km/h in 6.0 seconds, while the 390 hp 7.2-liter car does it in 6.1 seconds. Fuel consumption is 22.0 l/100km for all listed versions.
Which Plymouth Superbird to buy
- 6.9 MT (1 generation): the 425 hp manual version accelerates in 6.0 seconds, pairing the top power output with a Manual gearbox.
- 6.9 AT (1 generation): the same 425 hp and 6.0-second acceleration with an Automatic transmission, for those who prefer two-pedal driving.
- 7.2 AT (1 generation): the largest engine at 7210 cc with 390 hp; at 6.1 seconds to 100 km/h it gives up almost nothing to the 425 hp cars.
Every Plymouth Superbird on the used market is a 1970 car from a single generation, so there is no newer or older variant to weigh — the choice comes down to transmission and engine. With only 4 modifications and one body style, comparing candidate cars is straightforward.
Which Plymouth Superbird to avoid
No version is clearly dominated by the numbers. The Plymouth Superbird 7.2 AT trades 35 hp against the 6.9-liter cars but carries the bigger 7210 cc engine and stays within 0.1 seconds on acceleration (6.1 vs 6.0 seconds), while fuel consumption is identical at 22.0 l/100km across the range. All three notable versions share rear-wheel drive and the 1970 model year, so none stands out as the weak pick.
