Citroen AC4 Price Guide

The Citroën AC4 was the small Citroën of the late 1920s. It took the form of a practical, affordable four-cylinder car that sat below the B-series in the range and continued the company’s mission to make motoring accessible to the widest possible audience. The AC4 and the contemporary AC6 six-cylinder were the cars that bridged the gap between the early Citroëns and the revolutionary Traction Avant.

The Car

The AC4 used an 1,100cc overhead-valve four-cylinder engine in an all-steel body on a separate chassis. The range covered saloon, torpedo, and commercial variants including the taxi that became common on Parisian streets in the late 1920s. The AC4 sold in large numbers and maintained Citroën’s volume position while the company invested in the front-wheel-drive technology that would transform the industry.

Buying

The AC4 is a practical vintage Citroën well-suited to club use and gentle touring. Parts availability through the Citroën Car Club and French specialist suppliers is reasonable. The Citroën pre-war cars occupy a charming and affordable segment of the vintage market.
