Frankfurt: first station wagon model in the limelight

  • Date
    15 - 25 September 1977
  • Description
    The 123-series estate is presented to the public at the Frankfurt International Motor Show in the shape of the 240 TD, 300 TD, 230 T, 250 T and 280 TE. Other new passenger cars on display are the 450 SLC 5.0 with 5-litre V8 light-alloy M 117 engine and the 300 SD as first diesel variant of the S-Class. Bound for the US market, the 300 SD, which comes onto the market in April 1978, is the world’s first production car to have a diesel engine fitted with a turbocharger. This efficiency-boosting technology permits an increase in output of about 40 % with no appreciable additional fuel consumption. Also celebrating its world premiere is the O 305 G articulated pusher bus, which is based on the O 305 standard regular service bus. Revised versions of the light-duty and medium-duty trucks with permissible gross vehicle weights from 6 to 10 tonnes are also on show. In addition, Daimler-Benz demonstrates a pair of test vehicles with hydride storage tanks: a 280 E passenger car for petrol-hydrogen dual-fuel operation and an urban bus powered by pure hydrogen. From the current focuses of research work, the company presents an emission control system for petrol engines with three-way catalytic converter and oxygen sensor control.
Test vehicles with hydride storage tanks: Mercedes-Benz 280 E Saloon, 123 series, with petrol-hydrogen drive and an urban bus powered by hydrogen.
