Production Callum Vanquish 25 by R-Reforged revealed

Former head of Jaguar design, Ian Callum, has revealed the production-ready version of the Callum Vanquish 25 by R-Reforged – a limited 25-unit run of the redesigned classic Aston Martin that first went on sale back in 2001.

Priced from a hefty £450,000 ($A800,000) when production starts this September, the latest version gains a new name and numerous changes over the concept that was unveiled last year.

Based on the later, more powerful 5.9-litre V12-powered Vanquish S sold during 2004-2007, the Callum Vanquish 25 by R-Reforged is claimed to be subject to extensive changes.

As well as the exterior makeover, there's been a reworked and retrimmed interior, retuned chassis and engineering changes to the engine, exhaust and brakes.

In total, the Callum Vanquish features more than 350 changes over the original car, which the ex-Jag designer originally penned while working for TWR back in the late 1990s.

The alterations to the Callum Vanquish include a pair of new headlights that now incorporate indicators, allowing for a new front bumper that adds intakes for brake cooling.

Speaking of which, the old Aston now comes with powerful carbon ceramic rotors, addressing the standard car's brake fade issues on track.

Tweaked sills and some tidying up of the rear glazed area complete the changes to the profile, while at the rear there's a pair of new LED tail-lights and a large rear diffuser.

Gone is most of the original's chrome brightwork, replaced by body-coloured pieces.

Under the bonnet, thanks to the new exhaust and a redesigned carbon-fibre intake, power has been boosted to a more muscular 433kW – an increase of 45kW.

The powerful V12 is offered with not only the standard car's outdated automated manual, but a six-speed manual or a conventional automatic.

Riding 10mm lower and with a track that has been widened by 60mm, the Callum Vanquish gets a new set of 20-inch alloy wheels and a chassis tune developed by a team headed by a former Jaguar SVO engineer.

The result is claimed to be a GT with better body control and a more compliant ride.

Inside, the driver now sits 20mm lower on armchairs that have been reupholstered in Scottish-sourced leather. The steering wheel position has also been modified for a better driving position, while the rim itself is thinner for better feel.

Both the door cards and handles are bespoke, while a carbon or walnut veneer and Bremont-sourced switches and dials replace the old car's Ford parts-bin items. There's also the latest infotainment tech including Apple CarPlay and Android Auto.

A removable Bremont clock completes the updates.

Ian Callum expects the limited run of 25 cars to consist of both existing Vanquish owners and new customers, for whom the Scotsman's design consultancy will help source a suitable car for conversion.

“We strip the vehicle down completely so we have a consistent starting point,” he said. “The price will vary depending on the condition of the original vehicle and how much work is required to get to that initial baseline.”

As part of the build, buyers will have the choice of an 'infinite range of colours', while eight trim colours and three wheel designs are also available.
