1965 Spirit Of America Sonic I
Offered by RM Sotheby’s | Coral Gables, Florida | February 2025
People setting speed records sort of started happening as soon as there was a car. After WWII, things got a little more serious when guys started strapping jet engines to some wheels and heading off for the salt flats in Utah.
The first Spirit of America looked like a jet without wings. Craig Breedlove ran it at over 400 mph in August 1963. The FIA wouldn’t recognize it because the car only had three wheels. In October that year he ran 526 mph with the car, but ended up in a pond at the end of the run.
Over the next year and a half or so, Breedlove had this car designed. It had four wheels and a GE J79 jet engine from an F-4 Phantom II. In November 1965, Breedlove hit 600 mph in this car, which was the record that would stand until 1970. It was Breedlove’s fastest run of his career. After that, the car ended up in the Indianapolis Motor Speedway Museum, who is now selling it on an estimate of $500,000-$1,000,000. More info can be found here.
