The Aston Martin Cygnet has since been known as the quirky option offered by Aston Martin to clients as an extra runabout vehicle to accompany their new grand tourer. Being an obvious re-badging of the Toyota iQ, the Cygnet is then considered more of an accessory than a purebred Aston Martin vehicle. It seems then that someone in the British marque's factory has quite the sense of humor because Aston Martin have now created a one-off version of the Cygnet – with a Vantage S V8.

That's right, for some odd reason the folks from Aston Martin have shoehorned a complete 4.7-liter V8 into the Cygnet's puny engine bay. Considering that an engine less than half that size used to reside in the rather small space, Aston Martin had to modify the whole front bulkhead, transmission tunnel, and even had to use front and rear subframes from the Vantage to make it all fit.

430 PS worth of power is then sent to the seven-speed automated manual transmission mounted at the rear via a tiny torque tube which then ultimately sends power to the rear 19-inch wheels. Since the iQ started off with 16-inch wheels standard, carbon fiber wheel arches were then added to house the meaty 19-inchers all-around.

This Frankenstein 'Super Cygnet' conversion has taken its toll on the pint-sized city car's weight. Now weighing 1,375kg with all fluids in versus 920 kg stock, the V8 Cygnet has a lot more weight to push around. That said, it reaches 0-60 in 4.2 seconds with a top speed of 273 km/h. Rather terrifying stats for what is essentially a boxy city crawler, don't you think?

Aston Martin plans to debut the V8 Cygnet at the Goodwood Festival of Speed this weekend. Better squint hard when you watch it on screen.
