Joe Granatelli Sr. debuts at Indianapolis Motor Speedway — the start of a three-generation racing legacy that would reshape American motorsports.

Joe and his brothers Vince and Andy opened Grancor — a legendary speed shop in Chicago that became a hub for hot rodders and racers. This was where the Granatelli reputation for performance was forged.

Co-built the revolutionary Paxton Novi Turbine Indy cars. Set a world land speed record of 198.9 mph in a twin Paxton supercharged Studebaker Avanti.

Chief mechanic on the Indy 500 winning team — a feat he would repeat in 1973. His genius for extracting every last drop of horsepower was unmatched.

Joe returned to Victory Lane as chief mechanic — proving the first win was no fluke. Two decades of Indy dominance cemented the Granatelli name in motorsports history.

J.R. Granatelli founds Granatelli Motor Sports, carrying his father's legacy of precision engineering forward from a 42,000 sq ft facility in Oxnard, California.

Three generations deep, Granatelli Motor Sports now offers 10,000+ SKUs from a 42,000 sq ft facility — still engineering, still testing, still American made.
