Looking very similar to the 1927 Series AA Capitol, the wheelbase of the Series AB was increased by four inches to 107 in (2,718 mm).
The updated look was one of the first projects from GM's Art & Colour studio.

The Series AB was powered by Chevrolet's old 171 cu in (2,800 cc) four-cylinder engine, but with minor modifications to produce 35 hp (26 kW) at 2,200 rpm.
Four-wheel braking was also now provided.
