It’s okay if you hadn’t heard of the Excalibur RS before coming across this video; it won’t cost you your enthusiast card. That’s because there is only one of them in existence, painstakingly built over a period of eight years. The car was designed and built under the supervision of Robert Shaw, but it is actually a tribute to a much older car. That car was the Hawk, another one-off designed by Brooks Stevens all the way back in 1959. The Hawk’s influence is pretty obvious in the RS, as are a couple of other cars, but Shaw has managed to make the design his own, and the build quality of the car is also very much first rate.
