Joining the already-revealed Zagato Coupe and Volante, the Speedster and Shooting Brake will see the total production run for the Vanquish Zagato increased to 325 units, with just 28 examples of the Speedster and a further 99 Shooting Brakes to be built.
Based on the 'standard' Aston Martin Vanquish S, all Zagato variants are powered by a 5.9-litre aspirated V12 (though the company refers to it as a 6.0-litre) developing 444kW of power and 630Nm of torque.
Drive is sent to the rear wheels exclusively via an eight-speed Touchtronic III transmission.
Compared to the Volante, the Speedster forgoes the electric-folding fabric roof for an "uncompromising" roofless design, distinguishable from its soft-top relative by the two large 'Speed Humps' behind the seats, which represent Zagato's signature 'double-bubble' roof.
The Speedster otherwise remains largely the same as the wider Vanquish Zagato range, which also features carbon-fibre body panels, 'Blade' tail-lights inspired by the Aston Martin Vulcan, and an array of three-dimensional Zagato 'Z' motifs in the front grille and rear vent meshes.
All 28 Vanquish Zagato Speedsters have already been sold, with deliveries scheduled for 2018.
Meanwhile, the Shooting Brake is still to be revealed in its final production form, though the official rendering (above) gives an indication of what the two-seater hatchback will look like.
With production to commence sometime in 2018, the Shooting Brake features an extended roofline that incorporates Zagato's double-bubble roof design, along with glass inlays that let light "flood into the cockpit".
Also unique to the Vanquish Zagato Shooting Brake is the powered tailgate that reveals a "luxuriously-trimmed" rear cabin area complete with a tailored luggage set. Other highlights include a herringbone carbon-fibre fascia with anodised bronze rotary controls.
"We haven’t released Zagato models as a family before, at least not in this way, but the idea is not without precedent," said Marek Reichman, Aston Martin's chief creative officer.
"Think back to the DB7 Zagato and DB AR1, or the V8 Zagato Coupe and Volante, for example. We’ve simply taken things a few steps further."
"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," he added.
CarAdvice has contacted Aston Martin's local arm regarding local availability and pricing, though we do know that two or three Zagato Coupes found Australian homes this year.
