Aston Martin and Zagato have revealed the final two body styles their long-term partnership will spawn, an open-top speedster and a wagon-like shooting brake.

They join an already revealed coupe and volante to make up a series of four new limited-production Vanquish specials, of which a total of only 325 are planned for production.

Zagato has long made great cars extraordinarily rare, and beautiful, and the new Aston Martin-Zagato creations are no exception. Instead of hand-beating aluminum skin to form the unique, customized bodies of the Vanquish specials, Zagato is crafting the body panels from carbon fibre, matching the original production car’s construction methodology so as to maintain the same weight and handling characteristics.

The speedster will be the rarest of them all, with only 28 planned for production, while the other models in the British-Italian family will have production runs of 99 cars each. Every build slot has already been sold, with some buyers ordering one of each, says Aston Martin.

The unique Aston-Zagatos are based upon Aston Martin’s Vanquish S, powered by a naturally-aspirated V12 engine. All four derivatives will channel their V12’s 600 horsepower through Aston’s Touchtronic III transmission, which allows for relaxed automated shifting, or paddle-actuated sport shifting as desired.

All four specials have custom-tuned adaptive damping, further distinguishing them from regular production Vanquish models.

Fine detailing is found throughout all four cars, with unique “Z” embroidered upholstery; 3D Zagato “Z” motifs; and the finest quality leathers adorning all of them.

Aston Martin says the four Zagato specials present “something for everyone,” as each car has its own unique appeal.

“Why create a family of Zagatos? Well, many of our customers want different things. Some prefer the purity of a Coupe, but others love the idea of something more extreme, like the Speedster. And yes, some of them have ordered one example of each. There’s always an over-demand from our clients and patrons,” said Marek Reichman, Aston Martin Chief Creative Officer.

(Personally, we’d spring for the shooting brake if we had to choose.)

With such limited production numbers, Aston says the cars are worthy of future concours, as highly-desirable collectibles.

“We could easily fulfill demand for more cars than this, but we want Zagato to remain something very special. We’re creating collectibles, future concours cars. With only 325 cars worldwide, divided between 99 Coupes, 99 Volantes, 28 Speedsters, and 99 Shooting Brakes—they are still the rarest of the rare,” concluded Reichman.

Zagato CEO Andrea Zagato, grandson of company founder Ugo Zagato, is nostalgic about his company’s generational partnership with Aston Martin, and while Zagato works with other car companies to produce limited-production specials, it’s apparent that Andrea has a soft spot for the British marque.

“My family name is associated with all kinds of wonderful designs, but for many enthusiasts and collectors around the world those that combine the ‘Z’ of Zagato with the wings of Aston Martin are the most special,” said Zagato.

“Zagato’s relationship with Aston Martin began with my grandfather and the DB4 GT Zagato, almost sixty years ago. To have a creative ‘marriage’ thrive for three generations is something as unique as the cars themselves.”

Those lucky enough to have secured a build slot can expect delivery of their Zagato sometime in 2018.
