When Autosport recorded its Greatest Cars series of podcasts, we covered everything from junior single-seaters to sportscars, Formula 1 machines and Indycars alike. NASCAR got a passing mention, and this author made a case for one of the greatest Cup cars to be considered - but given the parochial nature of the series, it was admittedly in vain.
In the modern era, the 'Generation 6' NASCAR Cup cars are strictly regulated, identikit pieces of machinery draped in a facsimile bodyshell of each manufacturer's US-flagship consumer car. Today, the ovals (and sporadic 'roval' and circuit events) are occupied by collections of the Toyota Camry, the Chevrolet Camaro and the Ford Mustang GT. Sure, they may hold a passing resemblance to the road-going models, but the internals are far away from the real thing.
When you consider NASCAR's greatest cars, the modern machines are perhaps a little bit too formulaic to enter the conversation. They're great for racing, but they don't evoke quite the same frisson of excitement that some of the past oval-botherers used to.
