Jack Boison Nethercutt II (born December 22, 1936) is an American businessman, restaurateur, and former racing driver with Ferrari and Lotus.

[1][5] Nethercutt entered professional auto racing in 1956 at the age of 19 while also studying in college, getting his funding primarily from his father.

At the 1960 12 Hours of Sebring, Nethercutt finished in the podium 3rd overall and won the S3.0 class after 186 laps with American co-driver Pete Lovely, scoring 4 manufacturer's championship points for the eventual 1960 season winners Ferrari.

[8] Competing with the Ferrari 250 TR at the 1960 USAC Road Racing Championship, he and Lovely finished 2nd in class and 3rd overall behind Carroll Shelby and Ken Miles.

[6] From 1961 to 1963 he switched to a Lotus 19, competing in the Sports Car Club of America and achieved several podiums, including a victory at the 1962 SCCA Divisional.

[12] The Mirage was supposed to debut two years earlier, but his father J.B. was against the vehicle's construction and would not fund it, which caused Nethercutt to experience financial constraints leading to its delay.

[12] Racing experts claim that if the Mirage was completed on time a couple of years earlier, it would have been internationally competitive because of its revolutionary design from its low drag aerodynamics.
