I catched a look at a 79 300sd in the salvage yard today with turbo ,it had a born on date of 1/79 .It probably died from carbon buildup from what the injectors were telling .The exterior and interior were in good shape ,I wish I could of got it before it ended up at the boneyard,they wont let a whole car leave the lot after its dropped off ,shame too,Ive seen so many that could of been contenders for revival back to the road.

1977 300SD was the first year...pretty much the same car in 1979

missed it by "that" much...
may would have been 78 1/2... or a 79.

May 78 would be a 79, right?

yup, that is how I read it, but MB Doc said 77, so I posted that info... your guess is as good as any. I don't know if MB did any 1/2 years in 78, or if they just introduced it as a 79 model.

In May 1978 the model 300SD was introduced to the USA and Canadian markets. The new S-Class model - for the first time in the history of this vehicle category - was driven by a diesel engine. The 3.0 L 5 cylinder, which had proven so well in the types 240D 3.0 and 300D, was fitted with a turbocharger. The development of this unusual S-Class variant had been started with the goal to fulfil the lower consumption figures introduced by the US-government.

1977 - A turbodiesel for the S-Class

Another diesel model presented by Mercedes-Benz specifically for the American market caused a stir at the 1977 Frankfurt International Motor Show (IAA): the 300 SD was the first S-Class (W 116 series) from Stuttgart to be equipped with a compression-ignition engine. An exhaust-gas turbocharger provided for performance appropriate to the luxury sedan, boosting the output of the five-cylinder diesel familiar from the 123 series to 85 kW (115 hp). In May 1978 production of the model based on the US version of the W 116 series began. The three-liter diesel was fitted with a Bosch injection pump and a Garret exhaust-gas turbocharger and provided the 1.8-ton sedan with respectable performance: the top speed was 165 km/h; the S-Class Turbodiesel sprinted from standstill to 96 km/h (= 60 miles an hour) in 14 seconds. The diesel cousin could not match the unbelievable performance of the 450 SEL 6.9 of the W 116 series. But it made up for it with an average consumption of only 14 liters of diesel per 100 kilometers (16.8 mph) , while the S-Class with the M 100 V8 engine required 22 liters of premium gasoline for the same distance (10.7 mpg) - albeit a very common con-sumption figure in those days.
