Aston Martin V8 Cygnet: 4.7-litre 430bhp V8



The V8 Cygnet has been brought to life for a single customer through the ‘Q by Aston Martin – Commission’ service. This section of the British marque’s bespoke personalisation service allows the ultimate in freedom of expression when designing an Aston Martin and the V8 Cygnet continues to push these boundaries.

Developed in-house by Aston Martin’s engineers, the starting point for the project was a right-hand drive Cygnet steel body shell and panels. 

A roll cage was welded to this, becoming an integral part of the chassis in the process, while a new front bulkhead and transmission tunnel were fabricated from sheet metal to accommodate the characterful 4.7-litre naturally aspirated V8 Vantage S powertrain. Subframes and suspension are also derived from the previous generation Vantage and a steel fuel tank housing has been mounted in the boot area, utilizing every inch of space.


At the rear of the car the distinguishing new feature of the V8 Cygnet is the central twin exhaust pipes. The exhaust is a bespoke system with twin underfloor mufflers and catalytic converters. With relatively short distances involved from manifold to tail pipe the V8 Cygnet has a voice that belies its compact size.
 
The engine itself is the 4.7-litre, naturally-aspirated V8 that is more usually found beneath the bonnet of the previous-generation Vantage S. Bespoke intake trunking had to be designed and there are twin conical air filters. There is no sense in which the engine has been neutered for the Cygnet, however, with power and torque figures remaining at 430bhp and 490NM (361lb ft) respectively.

The gearbox is also taken from the V8 Vantage S with a seven-speed Sportshift II transmission taking care of the shifting. Power is transferred via a miniature torque tube to the 9.5” rear wheels, which are complemented by 275/35 Bridgestone tyres.

Weighing just 1375kg when full of fluids, the V8 Cygnet has a power-to-weight ratio of 313bhp/tonne. As a result, the V8 Cygnet is capable of accelerating faster than the V8 Vantage S with 0-60mph taking just 4.2 seconds. With a top speed of 170mph it is over 60mph faster than the regular Cygnet.
