Mercedes-Benz Medium Sedan · Typ 130
Rear-engined experiment for the people — the Typ 130 H.

The Typ 130's rear-mounted four-cylinder and compact packaging were a radical departure from Mercedes-Benz's front-engined norm, aimed at lower purchase and running costs for a broader audience. Independent suspension and a lightweight structure supported the project's economy-car ambitions, even as the company continued building larger, more conventional models for its established clientele.
Between 1934 and 1936, 4,298 examples were built — a respectable total for an experimental layout, though the Heckmotor concept would not define Mercedes-Benz's future direction. The Typ 130 remains a fascinating sidestep in the company's history, a volume-built rear-engined Mercedes decades before such ideas resurfaced elsewhere in the industry.

1 distinct series across 1934–1936 — each identified by its chassis and engine numbers from period factory data.
