Two sporty, elegant variants of the Mercedes-Benz Mannheim make their debut at the International Motor Show in Berlin: the 370 K, available as four-seater Special Convertible NC, and the two-seater 370 S, available as Roadster or Convertible.

The Mercedes-Benz Nürburg (W 08) is also offered with overdrive transmission and a 5-litre engine. This variant later acquires the designation Nürburg 500.

12/13 April 1931
The driver pairing of Rudolf Caracciola and Wilhelm Sebastian takes victory at the wheel of a Mercedes-Benz SSKL (W 06 RS) in the Mille Miglia, the 1000-mile race from Rome to Brescia and back, setting an average speed of 101.1 km/h over the 1635-km course. Caracciola thus becomes the first non-Italian winner in the history of the race. The SSKL (which stands for "Super Sport Short Light”) represents the final stage in the development of the S series and is only built as a race-trim two-seater. Under the bonnet is a 7-litre engine, which delivers 240 hp / 176 kW without and 300 hp / 221 kW with supercharger and enables a top speed of 235 km/h.

1 - 11 October 1931
Daimler-Benz AG presents the 170 (W 15) to the public at the Paris Motor Show. One innovative feature of this model is its progressive chassis concept. The 170 is the first series-produced Mercedes-Benz passenger car to be fitted with a hydraulic braking system as well as front and rear swing axles, i.e. independent suspension for front and rear wheels. As the smallest passenger car model in the Daimler-Benz range, the W 15 is the perfect response to the economic hardship caused by the Great Depression.
