Mercedes-Benz Large Sedan (W14)

The W14 was a pre-war Mercedes-Benz prototype program from 1928 — a compact 5/25 hp car that explored small-displacement four-cylinder packaging in the years before the Great Depression reshaped the industry.

Offered as saloon and cabriolet on the same short chassis, the W14 used a 1.3-liter four-cylinder engine and conventional rear-drive layout. It represented Mercedes-Benz's continued experimentation across the model range in the late 1920s, when the firm was still mapping its post-merger product strategy.

Mercedes-Benz built 56 W14 examples in 1928 — 28 sedans and 28 cabriolets. It was a limited prototype series, not a production Baureihe, and survives today as a rare document of inter-war development work.
