This photo captures one of NASCAR’s rarest creations: a genuine wing car from the sport’s brief but wild ‘aero wars.’ Built by Dodge and Plymouth to chase top speed with towering rear wings and extended nosecones, cars like this one dominated the 1970 season before a single rule change legislated them out of competition almost overnight. Read on to find out why that rule mattered so much, and why surviving examples are worth seven figures today.

NASCAR once wrote a rule so specific it applied to only a handful of cars ever built, and this photo shows one of them still slicing through a corner with its towering rear wing intact. By the time this shot was taken, the sport had already begun engineering this entire class of machine out of existence. A single number, buried deep in the rulebook, is the reason wing cars like this one nearly vanished from competition entirely, and it had nothing to do with horsepower. What that number was, and why it mattered so much, explains why cars like this one are now among the most valuable in muscle car history.

How the Aero Wars Started

Ford fired the first shot in 1969 with the Torino Talladega and Mercury Cyclone, kicking off what became known as NASCAR’s ‘aero wars.’ Chrysler answered with the Dodge Charger Daytona that same year, built with help from engineers borrowed from the company’s missile division and featuring an extended nosecone and towering rear wing designed for pure aerodynamic efficiency. Only about 503 Daytonas were built. Plymouth followed in 1970 with the Superbird, refining the formula further and building 1,935 examples to satisfy new homologation rules.

The Rule That Ended the Wing Cars

The formula worked almost too well, Daytonas and Superbirds combined to win 33 of 48 races during the 1970 season. NASCAR’s response for 1971 limited any ‘aero car’ to a 305-cubic-inch engine, or forced it to carry significantly more weight than its competitors, a rule that made the wing cars uncompetitive almost overnight. Combined with rising insurance costs and tightening emissions rules, 1970 turned out to be the wing cars’ only real season in the sun.

Why the Wing and Nosecone Actually Worked

The Daytona and Superbird’s extended nosecone reduced front-end lift at speeds over 190 mph, while the towering rear wing, mounted high enough to clear the trunk lid and catch clean airflow, generated genuine downforce rather than acting as pure decoration. Wind tunnel testing at the time confirmed the combination cut drag enough to add several miles per hour of top speed compared to the standard Charger and Road Runner bodies these aero cars were based on, which is exactly why NASCAR felt compelled to legislate them out of competition. Engineers reportedly tested multiple wing heights and nosecone lengths in the wind tunnel before settling on the final production dimensions, understanding that even small changes in wing angle could meaningfully shift the balance between straight-line speed and cornering stability at superspeedway velocities.

Richard Petty and the Superbird’s Legacy

Plymouth built the Superbird largely to lure Richard Petty back from Ford after he’d left Chrysler over the Charger 500’s handling issues the year before, and Petty went on to win eight races in a Superbird during the 1970 season. That direct connection between homologation-mandated street cars and factory-backed NASCAR competition is part of why Superbirds and Daytonas carry such weight with collectors today, these weren’t marketing exercises, they were genuine racing tools that happened to be sold to the public.

Homologation Rules That Forced Street Sales

NASCAR required manufacturers to build one street car for every two dealerships to qualify an aero package for competition, which is exactly why Dodge and Plymouth had to sell hundreds of nosecone-and-wing cars to ordinary buyers rather than keeping the aero package exclusive to factory race teams. Many original buyers found the cars nearly impossible to move off dealer lots at the time, with some Superbirds reportedly discounted or even converted back to standard Road Runner trim just to get them sold. Dealers sometimes resorted to creative financing or steep markdowns just to clear the required inventory off their lots, a stark contrast to how quickly identical cars would sell decades later once the collector market caught up to their significance.

Why So Few Survive Today

Because period buyers often saw these aero cars as oddly styled and hard to sell, a meaningful number were driven hard, wrecked, or had their distinctive nosecones and wings removed to look more like standard Chargers and Road Runners, a modification some owners performed simply because replacement wing-car-specific body panels were expensive and body shops discouraged the added weight and complexity. That combination of low original production and casual attrition is why genuine, unmodified survivors are so scarce compared to their build numbers alone. Some owners even removed the wing simply because it made parking in a standard garage or driveway more difficult, a mundane practical concern that nonetheless contributed to the slow attrition of unmodified survivors over the following decades.

Collector Values for Daytonas and Superbirds Today

A documented, numbers-matching Dodge Charger Daytona or Plymouth Superbird with its original nosecone and wing intact can bring seven figures at major collector auctions today, with Hemi-powered examples commanding the biggest premiums. Even six-cylinder or small-block Superbirds built purely to satisfy the homologation quota, cars few enthusiasts wanted new, now sell for well into six figures simply because so few wing cars of any configuration survive in unmodified condition. Auction houses now treat any verified sale of an original Daytona or Superbird as a bellwether event for the broader muscle car market, given how rarely a genuine, unmodified example changes hands in the first place.

The End of an Era in Stock Car Racing

The 1971 rule changes didn’t just end the wing car experiment, they marked the last time a factory built a street car purely to satisfy NASCAR homologation requirements at this scale, closing out an unusually direct link between showroom cars and the racetrack. Every wing car campaigned after that point ran under increasingly restrictive rules, and by 1972 the entire aero-car class had effectively been legislated out of NASCAR’s top series for good.

Spotting a Real Wing Car From a Clone

Because genuine Daytonas and Superbirds are worth so much more than a standard Charger or Road Runner, verifying the VIN, fender tag, and broadcast sheet against factory records is essential, reproduction nosecones and wings are widely available today, and a convincingly built clone can fool a casual buyer at a glance. Experienced appraisers look for consistent factory spot-weld patterns, correct VIN-stamped sheet metal, and documented ownership history before confirming a wing car is the real thing rather than a well-executed tribute build.
