Why it matters

The 150 (design name W 30) was a one-year sports model of 1934 in the small-car range of Mercedes-Benz. It was laid out with the four-cylinder engine ahead of the rear axle and the gearbox behind it, and it carried a three-speed gearbox with an additional overdrive. The factory archive counts only five roadsters of this type.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The archive dates the 150 to 1934 and lists the sports roadster at a price of RM 6,600. Its units-produced entry reads five roadsters (W 30) and six sports sedans (W 130); the sports sedan had no list price.

The chassis used a central-tube frame with fork end, independent front suspension by one upper and one lower transverse spring, and a swing rear axle with double coil springs.
