But since we're going that route (emphasis mine):
Critics of the car consider it underwhelming for such an expensive, powerful and high performance machine. Motoring journalists have been critical of the interior and the car itself for being too comfortable and lacking the sense of occasion present with other supercars.[53] Commentators who approve of the interior have criticised the luggage space as being "largely useless".[51] Journalists and other commentators often bemoaned the lack of the Jaguar V12 engine and other technical components fitted to the concept car. Contemporary reviews pondered on whether the sales performance and residual values would have been improved by sticking more closely to the specification of the concept car.[7]
Sales performance was disappointing. Jaguar had intended to produce up to 350 cars, but production ceased in 1994 with 275 production cars produced, not all of which had been sold; some left-hand drive examples were still available in 1997.[54][55]
My point was just that there was indeed a v6 Supercar. The XJ220 by all accounts was underwhelming from a quality perspective (it WAS a Jag after all), but I believe history shows that it was ahead of its time in the area of power train much like the Buick GN with smaller displacement and turbocharging. Now that technology has caught up (DI, faster processors, etc) ecoboost technology has been able to thrive. Who would have thought that the F-150 would have 4 engine choices, THREE of which are v6 variants.
