The Alvis TB 14 was a series of roadsters introduced in 1950. The TB 14 was a limited production sports car built on an Alvis TA 14 platform, but featuring an open body built by the coachbuilder AP Metalcraft. These sleek roadsters were powered by the same 1.9L inline four engine as the TA 14, but with twin carburetors which increased power to 68hp. A total of 100 examples of the Alvis TB 14 were built, with production limited to 1950.
