The default Formula M's body build resembles that of the Speed Star. It features red headlights similar to Metal Sonic's eyes, two blue ears with yellow insides on the front and back of the car, and yellow tires that look similar to Metal Sonic's torso.
Like other cars in Team Sonic Racing, its appearance can be customized with different paint jobs, performance parts and decals. Its horn can also be changed.
In Team Sonic Racing, Metal Sonic appears with the Formula M as his vehicle as a member of Team Eggman to join Dodon Pa's racing Grand Prix after Eggman was forced to assemble a team part-way through the competition by Dodon Pa.
