A show of innovations: cars and commercial vehicles

An improved product range is presented to the public at the Frankfurt International Motor Show. The key new additions include the 300 model with updated body and fuel-injection engine (internal designation 300 d, W 189). For the first time manifold injection is used instead of direct petrol injection found in the 300 SL. The 180 model debuts in an improved version (internal designation 180 a, W 120) powered by a 65 hp / 48 kW 1.9-litre engine. The 219 and 220 S models are presented with uprated engines and the optionally available Hydrak hydraulic-automatic clutch. The commercial vehicle portfolio is expanded to include the LP 321, LP 329 and LP 326 cab-over-engine truck variants. With the LP 321, meanwhile, Daimler-Benz offers a cab-over-engine truck in the medium-duty segment for the first time ex factory. Also celebrating its premiere is the new O 317 large-capacity bus with underfloor engine and air suspension, which capacity for up to 120 people. The fully enclosed variant of the Unimog (411 series) debuts in a version with a more spacious cab.
