The line between muscle cars and sports cars is blurrier than ever, with models like the Ford Mustang and Chevy Camaro being able to compete with Models like the Porsche Boxster, Jaguar F-Type, and even the Aston Martin Vanquish – at least in terms of style, anyway. But, there was a time when muscle cars were exactly that – cars with big muscle under the hood and chiseled bodies. For the younger crowd out there, the term American muscle means a completely different thing than it does to those of us that grew up around big blocks, carburetors, and engine bays without miles of wire routed every which way. To those of us who remember what muscle cars used to be, it’s easy to see that today’s “muscle cars” are slowly losing their heritage in the style department. Just take a look at this Mustang design that is based on the current Mustang, but tweaked with lots of old school cues, giving us a glimpse at what the current-gen Mustang should look like.
