1985 Mercedes-Benz 560 SEC

At the time of their launch, the 560 SEC and 560 SEL with this engine were the most powerful Mercedes-Benz production cars built until then.

The most spectacular novelty in the engine range was a 5.6-liter eight-cylinder which had been developed from the five-liter V8 whose stroke had been lengthened to give the car an output of 200 kW (272 hp). A version with an even higher compression ratio was optionally available and generated a proud 221 kW (300 hp), but could not be combined with a closed-loop emission control system. However, even without a catalytic converter, this so-called ECE version complied with the emission limits specified by the European Economic Commission (ECE).
