The Marussia B-Series was a series of sports cars built by Russian automaker Marussia Motors (pronounced ma-rus-ya). The series consists of the B1 and the B2; the cars are technically similar but are very different in design. The two vehicles had the same engines, layout, features, suspension, and brakes. Priced at over 4,000,000 ruble (from 120,000 € to 185,000 €), they were the first Russian supercars ever built.^[1] It featured a full carbon fiber car with aluminium chassis. About 3,500 units were planned to be built.^[2]

The B1 was the first car of the series and the first car produced by Marussia Motors. The chassis was built on an aluminum semi-monocoque design, and the engines were produced by a British engineering company Cosworth. Marussia had planned to only produce 2999 B1s.^[3] Engine power is 360 or 420 hp (268 or 313 kW), top speed is 305 km/h (190 mph) and it accelerates from 0–100 km/h (0-62 mph) in 3.2 seconds.^[1]

The B2 is the B1's successor, first shown to the public at the 2009 Frankfurt Motor Show. The differences between the B1 and the B2 are only cosmetic; the B2 offers a new, edgier design and a new, almost space-age interior. The plan was meant to give the car a more aggressive look. Some design features include highlighting the grille and intakes in black to contrast them to the car's body colour and emphasize some of the car's geometric elements, as well as styling the car's face to the shape of the "M" in the Marussia Motors logo. It used primarily parts from the cheapest European cars that are small and ultra-small, except the engine from Opel. The company hoped to get good power from it, as follows:^[4] Engine power is 420 hp (313 kW), top speed is 310 km/h (193 mph) and acceleration from 0–100 km/h is in 3.8 seconds.

The B2 was featured in Need for Speed: Most Wanted in 2012, Need for Speed Rivals and Asphalt 8: Airborne in 2013. In 2014 the car was also featured in Driveclub as a playable vehicle and in the official cover art for the PlayStation 4 exclusive.^[5]

In March 2012, a Finnish contract manufacturer of specialty automobiles, Valmet Automotive, and Marussia Motors entered into an agreement on the production of Marussia B2 sports cars at the Valmet car factory in Uusikaupunki, Finland.^[6] Marussia only created 500 units of this model, as were planned from the start and less than 12 months after hitting the market, all units have already been ordered.^[1]
