There is no consensus as to what a supercar even is, let alone when the first one appeared.
Recently, I found the term in a test of a V12 Lagonda printed in a 1938 issue of The Autocar, but some reckon it’s older even than that. Others, however, claim that its use in the sense we understand today is far more recent, becoming part of common speech only in the 1970s and referring only to cars built from the mid-1960s.
But my sense is that the car with the best claim to being the first true supercar is Mercedes-Benz’s 300SL ‘Gullwing’, an immaculate example of which you see photographed in company with its latest offering to the breed – the 63-years-younger Mercedes-AMG GT R.

So far as I am aware, the SL was the first to reset our understanding of what a road car could do. Even in 1954, there were some that could live with its performance, but these were racing cars capable of being driven on the road only thanks to regulations that required that ability. But although it did race, that was not the Gullwing’s purpose.
Indeed, being fundamentally designed for street use is as key a strand of supercar DNA as genuinely extraordinary performance for the standards of the day. Other top priorities include an appearance as arresting as it is exotic, an unaffordable price and the provision of pure driving pleasure. There are saloon cars, estates and even SUVs that have had supercar performance bestowed upon them, but this does not make them supercars any more than painting stripes on donkeys makes them tigers.
The GT R has more in common with the Gullwing than its frontengined, rear-drive, two-seat configuration and a three-pointed star on its nose. It has the correct supercar approach, too. Neither car is particularly practical, but nor are they so impractical as to be mere short-distance recreations, because that would tip them more towards being sports cars unless countered by simply unbelievable performance and presence. Both are cars you’d relish driving all day long. Both are sufficiently civilised on the motorway to make the journey to the mountains actually enjoyable rather than merely tolerable and both offer outstanding levels of entertainment when you finally arrive. Neither is intended or will be used primarily as a track car, but both – by the standards of their era – are entirely at home in that environment.
Charting the course from Gullwing to GT R plots a graph characterised by a gentle upwards sloping line of performance, punctuated by occasional giant leaps. A standard is set and steadily improved upon until someone gets bored and does something seen at the time as entirely nuts but that, in a remarkably short period of time, becomes adopted as the new norm.
