Could an Aston Martin Cygnet city car powered by one of the brand’s massive V12 engines be a legitimate production reality?

Well, going on recent industry banter, Aston Martin has already completed a feasibility study on an engine-transplanted Toyota iQ-based Cygnet, with positive results.

UK publication Autocar says sources at the British marque have suggested the feasibility study showed the 6.0-litre V12 powerplant seen under the bonnets of cars like the DB9 and new Vanquish fits into the baby Aston’s engine bay without “extensive modifications”, although admits “significant but not insurmountable” upgrades would be necessary.

Considering the engine produces 428kW and 620Nm when encouraging the 1739kg Vanquish, power would likely be stemmed to shift along the 988kg Aston Martin Cygnet, normally propelled by a 72kW/125Nm 1.33-litre four-cylinder.

While Autocar believes that Aston Martin could well end up going ahead with the plan, if customer demand were to prove sufficient, others are convinced the rumour is just that.

CarAdvice has contacted Aston Martin for comment.

While a V12-powered Cygnet production car sounds like a pipe dream, the idea is somewhat reminiscent of the Nissan Juke-R, a compact crossover impregnated with the 404kW/628Nm twin-turbocharged 3.8-litre V6 powerplant from the GT-R supercar. Nissan is producing a handful of Juke-Rs for fanatical customers who are happy to part with £400,000 ($620,000) for the insane little SUV.
