There isnt a lot of cars even today that can beat a good Cobra, but if you have the money or have been vetted by Ferrari, then this little limited car called the FXX (860bhp) will make any Cobra look very very slow on race circuit,

But I still like my Cobra, because it is simpler and I can build and repair it!
