By the tail end of the 1960s production-based racing was big business for automakers, and the mantra of “win on Sunday, sell on Monday” was a crucial strategy for marketing road-going high-performance machines. Low-slung models like the Chevrolet Corvette and AMC Javelin duked it out on road courses while Hemi ‘Cudas and Mustang Boss 429s went toe to toe at the drag strip, many with factory backing on some level. But perhaps nowhere was the competition as heated as it was on America’s high-speed ovals.
After Chrysler had determined that the Dodge Charger 500 wasn’t going to compete in superspeedway races due to its inherent issues with aerodynamic drag, they headed back to the wind tunnel in search of a more radical design. This would result in the Charger Daytona and its Plymouth counterpart, the Superbird. These “wing cars”, as they came to be known, would immediately begin terrorizing NASCAR racing, with a Daytona winning its first race out at the Talladega 500 and achieving unprecedented top speeds.
Models like the 1969 Cyclone Spoiler homologation car shown here helped Ford and Mercury keep the winged Mopars from winning the Grand National event in 1969 – David Pearson took the title in a ’69 Talladega – but after Bobby Allison and Bobby Isaac won five of the last six races in the season between them in Dodge Charger Daytona, it was clear that the Ford camp had their work cut out for them. This was compounded by the fact the upcoming redesign of the Mercury Cyclone and Ford Tornio for 1970 was notably less aerodynamic than the outgoing machine.

Ford was concerned – and rightfully so. Wind tunnel testing had shown that the 1970 Torino Sportsroof wasn’t going to be as fast as the outgoing ’69 model, so it was clear some dramatic aerodynamic changes were needed if the Torino Talladega and its Mercury counterpart, the Cyclone Spoiler, were going to give Chrysler’s wing cars a run for their money.
During spring of 1969, Larry Shinoda, director of Ford’s Special Design Center, got his staff together to begin working on an aero kit for the Torino and Cyclone that would serve as a counterpunch to these wild new Mopars. Mercury’s version would be known as the 1970 Cyclone Spoiler II. It would ultimately become one of the rarest Mercury muscle cars of all time.

Shinoda’s team included stylist Harvey Winn, who had previously helped Dodge design the sheet metal for the second-generation Charger, and Ed Hall of race engineering firm, Kar Kraft. The motorsports specialists at Holman Moody were also tapped for the project to oversee the engine and suspension development on the racing side.
As had been the case with the Daytona and Superbird, in order to make the race car eligible for use in the NASCAR series, Ford and Mercury would need to produce a number of road-going examples of their new racing machines.
Like the Dodge Charger Daytona and Plymouth Superbird, the idea behind the Cyclone Spoiler II's outlandish front clip was to cut through the air with minimal drag while reducing front end lift at the speeds the race cars would see during competition. Ford and Mercury’s designers wanted to take a more comprehensive approach than Dodge and Plymouth had with their aero cars - which had their front clips essentially tacked on to a standard car - by totally designing the bodywork from the firewall forward | Photography from Legendary Collector Cars / Richard Fleener
Planned as 1970 models, these homologation specials would share much of the bodywork and fundamental design with the standard Cyclone and Torino road cars, but with an entirely new front end from the firewall forward, that was designed to cut through the air with minimal drag. The Blue oval’s Boss 429 big block would serve as the top-spec motor for the new models.
The sole surviving Cyclone Spoiler II is outfitted with a Boss 429 street motor with 10.5:1 compression, forged pistons, a dual-plane aluminium intake, and a Holley 750 CFM carburettor. The combination is said to be good for 375 horsepower and 450 lb-ft of torque | Legendary Collector Cars / Richard Fleener photo
The project got underway with haste in spring of 1969 and by the summer, Ford was already out testing prototypes at Daytona. While Ford and Mercury appeared to be on track to bring the race and road cars into production in time for the upcoming season, unforeseen issues quickly began to mount.
For the 1969 race season, manufacturers had been required to build a minimum of 500 road-going examples of their race car. Development of these cars was often relatively expensive and the resulting sales were often lukewarm at best – race cars rarely make for great street cars, after all. But for the OEMs it was a necessary evil – even built at a loss, these models served a larger purpose in their marketing efforts, and 500 cars wasn’t an especially tough pill to swallow for large automakers.
However, once NASCAR president Bill France caught wind of Ford and Mercury’s plan to one-up the winged Mopars, he decided he’d had enough of the automakers’ shenanigans and revised the homologation rules, raising the minimum number of production cars from 500 to 3000 in a deliberate effort to coax automakers into returning to more conventional stock car designs.
While the road-going version of the 1970 Mercury Cyclone Spoiler II would wear a unique nose, everything from the firewall back was more or less standard Cyclone Spoiler hardware.

While that alone might have been enough to derail Ford and Mercury’s strategy to regain dominance in the series in the upcoming race season, internal shifts within FoMoCo were also working against the Cyclone Spoiler II and Torino King Cobra projects.
By the summer of 1969 internal strife was brewing between the two camps of Ford president Bunkie Knudsen and Henry Ford II. By September Ford had fired Knudsen, and with Shinoda being firmly within the Knudsen tribe, he was dismissed by the VP of design, Gene Borndinat, two weeks later.
The team working on the ’70 Cyclone Spoiler II’s Ford counterpart, the Torino King Cobra (seen here), was roughly two months ahead of the Mercury project in terms of development.

With Shinoda out of the picture, his team’s projects were largely left to languish and combined with the new NASCAR homologation rule, the fate of the Cyclone Spoiler II and Torino King Cobra were in serious jeopardy.
The final nail in the coffin for the program came when Knudsen’s replacement, Lee Iacocca, decided to slash Ford’s motorsport budget by 75-percent, effectively bringing an end to the two models before production began. Just a handful of Torino King Cobra prototypes would be built – most estimates put the number at five cars.
The Cyclone Spoiler II project was roughly 60 days behind the Torino team and just two examples had been completed before they pulled the plug. According to NASCAR team owner Bud Moore – who would acquire a pair of the Torino King Cobra prototypes 1971 – one of the Cyclone Spoiler II cars was destroyed while the other came into the possession of Lincoln-Mercury vice president Mose Lane.
Steve Honnell, an engineer who had been a service specialist for Lincoln-Mercury from 1964-1974, ended up purchasing another one of the Torino King Cobra prototypes from Holman Moody shortly after the program got the axe. Years later his friend Larry Shinoda mentioned in passing that the lone surviving Cyclone Spoiler II had ended up with Mose Lane.

After an exhaustive search, Honnell ended up at the farm of an Amish family in Indiana that had purchased the land from Lane’s estate after he passed away. Out in a remote barn on the property was a thoroughly worn out 1970 Mercury Cyclone with an experimental VIN, along with Boss 429, four-speed, 4.57 Detroit Locker, and “429 SP” special production stickers under the hood. Honnell purchased the car and quickly set to work bringing the Mercury back to life.
He completed the five-year restoration just in time for Ford’s 100th anniversary in 2003. Today, Honnell’s Cyclone Spoiler II serves as the only original example of what Mercury’s 1970 NASCAR season could have looked like had the Aero Wars not come to an untimely end.
