Despite finding my motoring love in classic front-engine watercooled Porsches, the "dream car" I always wanted since I was a kid was an 1970 Plymouth Superbird in Alpine White/white interior with bucket seats, the 426 Hemi and 4 speed transmission.
The Superbird, based on the Roadrunner, was born to fight NASCAR's "Aero-wars" of the late '60's & early '70's. These were the days when the make of the car usually was more important than who was driving it. Detroit was very cognizant of the old adage "win on Sunday, sell on Monday", and in 1969, Mopar was not winning. Ford had introduced the slippery Torino Talladega and the sister Mercury Cyclone GT in 1968 and immediately began winning on NASCAR's high profile superspeedways, which were located in Detroit's #1 market of the day, the US southeast.
Chrysler's competitors, the Charger and Roadrunner, despite their power advantage with the Hemi engine, were not aerodynamic enough to offset the Fords, though the Charger was better than the boxy Roadrunner. Plymouth's lead driver, Richard Petty, wanted to switch to Dodge for 1969, but Chrysler nixed the idea, so Petty jumped ship to Ford. Petty proved prescient as through the first half of '69, the newest Fords were even better aerodynamically than the upgraded Charger 500.
Mopar engineers went to work and midway through the '69 season they introduced the Charger Daytona. Based on the Charger 500, it added a drooping nosecone and fixed high wing to the rear deck. The resulting monstrosity immediately won straight out of the box at Talladega and went on to amass a favorable record through the rest of the '69 season.
Petty, did not have the success he had hoped for with Ford in '69, (Holman-Moody, the Ford racing parts distributor, was an on-track competitor of the Petty's and often held up critical parts deliveries), so when Plymouth called Petty and dangled the new Superbird, Plymouth's version of the winged-warrior, Petty bit and went back to Mopar. The Superbirds did well, winning 8 races in 1970.
Rule changes in 1971 rendered both winged cars uncompetitive, so they were quietly retired.
On the street, in order to homologate the Superbird, Plymouth built @ 1935 units, one for every dealer. Sales were disappointing to the point that some dealers removed the nose cones and wings. @ 505 Daytonas were built the year before, homologation rules were different in '69.
58 Superbirds were built with the 426 Hemi/4 speed combo, making them the rarest of these rare-birds.
