The Volante follows the success of the Vanquish Zagato Coupé, which was first seen in concept form at Villa d’Este in May.
Like the Coupé, the Volante has a run of just 99 models, expected to cost in excess of £500,000 each.
The model is the latest in a long partnership with Italian design house Zagato that dates back to 1960 when the DB4 GT Zagato was created. Previous Aston Martin Zagato convertibles include the V8 Vantage Volante, first shown in Geneva in 1987, and the DB AR 1 from 2003.
The DB AR1 was developed as an open-topped Zagato-bodied DB7, also limited to 99 units and, like the Vanquish Zagato Volante, designed for the US market.
The Vanquish Zagato Volante shares it proportions with the Coupé and features round tail-light reflectors that use the same LED technology as the Aston Martin Vulcan supercar. Twin cowls behind the front seats leading towards the luggage compartment conceal a folding hood, derived from the mechanism used in the standard Vanquish Volante. There are also carbonfibre sills around the lower body.
Aston Martin design boss Marek Reichman said the brand has “endeavoured to create an elegant, flowing shape that emphasises the car’s sculpted rear haunches”.
The naturally aspirated 5.9-litre V12 engine, which was developed and engineered at Aston Martin’s headquarters in Gaydon, has been uprated from 568bhp in the standard £204,995 Vanquish Volante to 592bhp, with a predicted 0-60mph time of 3.7sec.
The interior features carbonfibre, anodised bronze and Bridge of Weir leather, with a quilted ‘Z’ pattern on the seat and door sections and an embossed ‘Z’ motif on the headrests and centre console.
Aston Martin said the model is a “powerful addition to the Aston Martin and Zagato lineage, embodying Aston Martin’s inherent refinement and capabilities, as well as Zagato’s characteristic design details”.
