Aston Martin Cygnet with a Vantage S 4.7 L V8

This very special Aston Martin Cygnet was built for a customer through the company’s “Q by Aston Martin” customization service. They started with a right-hand drive Cygnet body and fabricated a custom roll cage, firewall, and transmission tunnel. Under the small hood sits a 4.7 L AJ37 V8 connected to a seven-speed Sportshift II transmission both from a Vantage S. The engine sends its 430 hp and 361 lb-ft of torque through a very small torque tube to a limited-slip differential. The 1,375 kg (3031 lb) car now sports a 170 mph top speed and can sprint from 0-60 mph in 4.2 seconds thanks to the 313 hp/tonne power-to-weight ratio.
