Aston Martin Cygnet with a 430 hp 4.7 L V8

The last time we shared the Aston Martin V8 Super Cygnet was in 2018 at Goodwood FoS. The wild little car is back. The original owner is listing it for sale on Nicholas Mee in the UK. The Super Cygnet was designed and built over 10 months by Aston Martin’s engineering and Q by Aston Martin customization service. The factory 1.3 L inline-four was swapped for a 4.7 L AJ37 V8 from a Vantage S producing 430 hp (316 kW) and 490 Nm (361 lb-ft) of torque. Behind the V8 is a seven-speed Sportshift II transmission, small torque tube, and limited-slip differential. Keeping the extreme power-to-weight ratio (313hp/tonne) in check are V8 Vantage S six-piston front brakes and four-piston rear brakes.
