Based on a Toyota iQ, the Aston Martin Cygnet was a short-lived luxury city car that failed to sell. This one-off swaps the tiny engine for a huge V8.

Aston Martin went bonkers when it made the Cygnet in 2011, and sold it for a few years. Why on earth did an automaker, known for V8 and V12-powered grand tourers like the Vanquish, create a city car based on a Toyota?

A one-off V8-powered Aston Martin Cygnet has come up for sale. The factory-built custom has a 4.7-liter engine from a Vantage S. In 2018 the Super Cygnet made its debut at the Goodwood FoS. In the late 2000s Aston Martin’s then-boss Uli Betz greenlighted a wacky plan to badge-engineer the Toyota IQ city car to create an Aston-branded urban runaround.

When first announced in 2011, the Aston Martin Cygnet piqued interest globally: a tiny sub 845kg (curb weight) hatchback with Aston mechanical gubbins. Where do I sign? Instead, the world received an Aston Martin-attired Toyota IQ.

Aston Martin built exactly one copy of the V-8-powered Super Cygnet, and now, this hilarious creation is available for public sale for the first time. Listed via Aston Martin seller Nicholas Mee in the United Kingdom,

The 'Super Cygnet' is a unique creation by the British luxury vehicle maker's Q Division that has never been recreated since, making this a genuine one-off motor.

Your chance to own the littlest supercar of them all has just appeared out of the blue, because the unhinged 4.7-litre V8-powered Aston Martin Cygnet is up for grabs for the first time. Built as a one-off by the boffins at Aston’s Q skunkworks division in 2018 and maintained by Aston since then,
