The Massacro, like its real-life counterpart, features a large integrated CFRP element across the lower half of its front bumper.
Unlike all 21st century Aston Martin production models (excluding the Cygnet and V12 Zagato), the Massacro does not include chrome trim around its side windows or on any side formations. The car also features a tall front quarter panel duct, unlike most Aston Martin models. Like its real life counterpart, the cars' sides feature an integrated CFRP side skirt elements.
The Massacro's rear fascia design is similar to the real 2nd Generation Vanquish, with a panel between the tail lights and the manufacturer logo in the mid upper area, giving it more resemblance to that of the Rapid GT. There are however big differences in the plate and exhaust area along with a more pronounced spoiler outline. The overall shape and greenhouse area strongly resembles that of GTA IV's Super GT.
The Massacro in short is an all around great performer, having exceptional braking, as well as the best top speed in its class rivaling the Zentorno and the Turismo R. Handling however, is where the Massacro falls short, as it does have trouble keeping grip at high speed turns, although in the hands of a skilled driver, this is not much of a problem.
The vehicle is stated in the website to have a 6-liter V6 engine capable of pushing 480hp. Its engine model, however, takes the form of a twin cam Inline-4, coupled to a 6-speed gearbox in a front engine, rear wheel drive configuration.
A special pre-modified variant of the Massacro can be seen driving around Vinewood Hills randomly, sometimes parked inside garages. The following set may spawn only in story mode. The car appears heavily modified and pink in colour.
Pre-modified variants of the Massacro can be seen driving around Los Santos randomly. The following two sets may spawn only in story mode. The vehicles appear in set color sets with the same modifications.
Like the randomly spawning modified Massacros, two sets of Massacros may spawn outside Los Santos Customs, pre-modified. These again only spawn in single player. The vehicles appear in set color sets with the same modifications. They will not spawn with any of the default extra components. These variants are named "LS_CUSTOMS_MODDED_SP" and use the exact same modifications and colors as the Business DLC Sports Modded sets.
The Massacro is part of three vehiclemodelsets, "LS_CUSTOMS_MODDED_SP", "BUSINESS_DLC_SPORTS_MODDED" and "MASSACRO_DLC_MODDED". The first allows the Massacro, among other cars, to spawn outside Los Santos Customs heavily modified, and in other places around the city, the second allows the Massacro and Jester to spawn heavily modified in specific locations, and the last allows a unique modified pink Massacro to spawn around Vinewood Hills. They only spawn in GTA V.
The name Massacro is Italian for massacre, a word related to vanquish, which is the name of the Aston Martin model the car is based on.
Similar to the modelling error of the F620, the engine model for the Massacro is an Inline-4.
The Massacro has a similar rear end to the Rapid GT and Exemplar, albeit with a different exhaust configuration and a more pronounced rear lip spoiler. This might be a reference to how almost all Aston Martin models look the same.
