This is an injection plastic Mini 4WD car model.
From the Tamiya website:
This is a Mini 4WD racing machine, which recreates the much-loved Aero Avante body. This specific version comes in a Limited-Edition black color and it sits on top of the aerodynamic AR chassis.
The AR chassis features a dual-shaft motor that drives both the front and rear wheels for optimum power transmission efficiency. The chassis itself has been engineered with aerodynamics in mind, with the monocoque main frame featuring a ground-effect design with channels to ensure smooth air flow. With a battery and motor layout that emphasizes good balance, the chassis is a perfect base upon which to install the wide range of available performance-enhancing Grade-Up Parts.
Requires 2 R6/AA/UM3 batteries (not included).
