The Excalibur automobile is a car styled after the 1928 Mercedes-Benz SSK by Brooks Stevens for Studebaker.
[2] Stevens subsequently obtained engines from General Motors through his friends GM executives Ed Cole and Semon "Bunkie" Knudsen.
These were Chevrolet 327s in 300-brake-horsepower (300 PS; 220 kW) Corvette tune, making the 2,100-pound (950 kg) Excalibur a strong performer.
With the standard 3.31:1 rear axle, acceleration from 0–60 mph (0–97 km/h) took less than six seconds.
[2] The American comedian Phyllis Diller was a notable proponent of the Excalibur automobile, and owned four of them.
