Here's a detail of the $2.3 million Aston Martin Vulcan.

The circuit-only Aston Martin Vulcan is one of the rarest hypercars available. Only 24 units were produced, priced at $2.3 million each. So how does one go about detailing such a rare and expensive car?

Very carefully. As this Topaz Detailing video shows, it's a meticulous process that uses multiple cleaning solutions and multiple passes through panel gaps, wheel arches, and any other place dirt might hide.

Topaz also applied a paint protection film to this particular Vulcan. This is a transparent material that covers the painted surface and helps prevent stone chips and other potential damage. Applying this film is like applying water slide decals to a model car; the material adheres to the wet surface but can be moved for proper alignment.

Introduced in 2015, the Vulcan was designed specifically for circuit driving, but some cars were later modified for street use. It is powered by a naturally aspirated 7.0-liter V12 engine with 800 horsepower. Developed by Aston Martin's motorsports division, the engine is located front midship for weight distribution.

At the time of its unveiling, Aston said that the Vulcan's power-to-weight ratio was better than that of the Vantage GTE race car running in the World Endurance Championship at the time. This was thanks in part to a carbon fiber monocoque sourced from Multimatic, the company that built the Aston Martin One-77 supercar and now builds the Ford GT.

The Vulcan also features a racing-style push-rod suspension system and is fitted with Multimatic's Dynamic Suspension Spool Valve (DSSV) adjustable dampers.

Despite these impressive specs, the Vulcan could soon be overtaken by another Aston hypercar.

The Aston Martin Valkyrie was developed in conjunction with the Red Bull Racing Formula One team. It boasts 1,160 horsepower from a Cosworth-developed 6.5-liter V-12 engine and a KERS-style hybrid system.
