This is a 1937 Alfa Romeo 6C 2300 B Gran Turismo. This model is a wonderful and important innovation compared to the previous version in terms of engine power that, despite being a bit lower than the first type, it gained a stronger torque together with a larger range of action. But maybe the most interesting improvement resides in the suspensions because the 6C 2300 B introduces the fully indipendent suspension system, for which design Alfa Romeo factory calls no less that Ferdinand Porsche!
