This is a plastic or cold-cast (porcelain-like) display car model.
From the Good Smile website:
A model of the Miku BMW from its final race in the 2013 season!
The GSR Hatsune Miku BMW 2013 racing car that achieved 3rd place in the yearly ranking of the 2013 season is joining the miniature car series!
The colorful, speedy-looking design as well as each of the sponsors logos have all been faithfully preserved on the miniature version. The chassis makes use of ABS resin for a faithful rendition of the original.
