1967 Autodynamics D-4 Mark IV

Ray Caldwell created the company, Autodynamics, along with the help of friends Del Trott and Don MacSorely, in 1962. American-born Caldwell had studied at Harvard Business School and was passionate about racing. he spent much of his free time racing his 1932 Ford Roadster, and later competing in SCCA-sanctioned races. He joined the Air Force in the early 1960s and spent some time in Europe. His free time was spent racing in European races and rallies with his Porsche Super 90.

The creation of the Formula Vee Series in the early 1960s provided an opportunity for many aspiring racers and builders. Customer cars were in high demand, and newly formed Autodynamics decided to gauge interest in an FV racer by running an ad displaying a drawing of their design. The response was tremendous, with over 1000 interested inquiries. Autodynamics collected money from a few interested buyers and began work on the new machine. The first car was ready for the 1964 FV Season, and Caldwell proved the car's potential by driving it to the SCCA National Championship. The first series of Formula Vee racers were dubbed the D-1 MK1. They utilized a Volkswagen engine and gearbox with a trailing link front suspension and swing axles in the rear. The body was constructed from fiberglass and rested on a space frame chassis. In total, there were around 186 examples created.

The first few years of production were difficult for the company. As with most businesses, it is hard to turn a profit in the first few years. It was not until 1967 that the company began making a profit, and by this time, it was producing over 60 cars a year.

In 1967 the D-4 was introduced, and it was a new machine in many ways. It had a new chassis design and improvements to its suspension components. It was not only a more modern and competitive FV racer than its predecessors, but it was also more expensive. The cars experienced some teething problems; at the Nassau Formula Vee race, it finished ahead of the competition only to be disqualified later for having valve springs that were considered 'illegal'.

For customers that required more room in the cockpit, the D-4A model was available. It provided the room needed for larger customers, and 148 customers took advantage of this more-accommodating machine.

The D-4B saw production in 1969 and 1970. It featured a newly designed body and similar mechanical components to its predecessors. Around 65 examples were produced. This would be the final Formula Vee created by Autodynamics; the cars created after 1970 bore Caldwell's surname.

Caldwell created new Formula Vee racers for the 1971 season that introduced new designs and features not seen on FV's before. The designs would soon be imitated by other marques. Caldwell also created cars for Formula Ford, Formula Super Vee, and even a couple of Pro-Series Cars.
