MERCEDES BENZ "Grosser Mercedes" Stadt Coupe (W07) 1933-1938 Photos, engines & full specs

Introduced at the 1930 Paris Motor Show, the Typ 770 was one of the most expensive cars on the market and was offered in a few bodywork versions, and all cars were hand-assembled.

But the German automaker didn't stop developing the vehicle after the launch. Apart from the sedans and different convertibles, it also made the Stadt Cabriolet (City Cabriolet). The idea behind the project was that the vehicle owner would stay in the back, in a closed cabin environment. In contrast, the driver and the side passenger were under the open sky. Thus, those in the front couldn't hear what was discussed behind the glass panel that separated them.

Like the rest of the W770 range, the Stadt Cabriolet featured a V-shaped radiator at the front. In addition, the curved front fenders were extended on the sides and continued with the side steps that eased the ingress and egress from the vehicle. The rear-hinged doors also allowed the passengers in the cabin to get in and out faster and more comfortably. Behind the cabin, the automaker installed a rack with a removable crate as a trunk. Furthermore, the two spare wheels were added to the back on a separate cradle. When the trunk was removed, the spare wheels' cradle could've been tilted forward.

The driving post featured a pair of seats and the usual Typ 770 dashboard with center-mounted dials and gauges, and the gear stick was floor mounted. In addition, a secondary lever activated the overdrive gearing, which allowed the vehicle to run at higher speeds with lower engine revs.

Under the long hood, Mercedes-Benz installed an inline-eight gasoline engine that produced 150 PS (148 hp). But the automaker also offered an option for a supercharged version that provided 200 PS (197 hp). Stopping power was ensured by four power-assisted drums.
