McLaren M4B

The M4B was the 1967 Formula 1 car raced by Bruce McLaren. The McLaren M4B's F1 Grand Prix debut came at Monaco 1967. Its short wheelbase made it surprisingly competitive. McLaren ran as high as third before a pit stop to replace a flat battery dropped him back to fourth at the finish. At the next event, the Dutch Grand Prix, Bruce McLaren finished 14th in qualifying. On the second lap of the race, McLaren crashed out, running the only M4B. The car was later repaired, but caught fire during a test at Goodwood and was written off.

The M4B is the first group project from the Garage. https://forum.studio-397.com/index.php?threads/announcing-the-garage.54824/
Its physics are made in collaboration with smbrm, Miro, Devin and Jokeri. The sounds were made by wolferl and deep-strike. The stunning car model is made by Klaash and Crossply as part of their ongoing F2 project.

These amazing looking F2 models will also each receive their own physics, which will be created as part of the second project of The Garage. Everyone is invited to join (read first post please)!
