The B7 model was the first snowmobile mass produced by L’Auto-Neige Bombardier. It was designed for commercial use, and could carry up to seven passengers. Unlike the regular model, it had no side windows. Starting in 1940, the B7 was equipped with a new suspension system for better traction; spoked wheels were replaced with solid steel wheels, thus eliminating the risk of snow accumulation in the system.
