Aston Martin is putting the final touches to the Vanquish Zagato Shooting Brake and was recently snapped testing a prototype on the M25 highway in the UK, with the pic uploaded to Reddit.

The British manufacturer released renderings of the fourth member of the Vanquish Zagato family in October last year, confirming that it would join the Coupe, Volante and Speedster.

The Vanquish Zagato Shooting Brake is based on the Vanquish S, but has undergone a series of comprehensive modifications to entirely alter its persona and looks. Like its siblings, this involves all-new bodywork the includes a sculpted front grille, circular daytime running lights, sexy surfaces and an overhauled rear end. For the Shooting Brake, an elongated roof makes it stand out from the rest.

Unlike the car shown in the official renderings, this prototype doesn’t feature a gloss carbon fiber roof. In fact, it’s exterior appears to be painted exclusively in matte red, including the rear diffuser and side air vents. It doesn’t look quite as good without the black accents, but there’s no doubt the production model has one of the best-looking shapes in the industry.

As with the Coupe, Volante, and Speedster, the Shooting Brake is powered by an the Vanquish S’s naturally-aspirated 592 hp V12. Like the Coupe and Volante, Aston Martin will build just 99 examples of the Shooting Brake; the Speedster will be more exclusive than the rest, as just 28 units will be made.
