In March 1968 Daimler-Benz presented a car at the Geneva Motor Show which on closer inspection revealed itself to be a combination of the 109 series Type 300 SEL introduced in 1965 and the Type 600 ‘representation sedan’. Out of the latter came the 6.3-liter V8 engine and automatic transmission, whose 250 hp (184 kW) accelerated the new model from 0 to 100 km/h in 7.4 seconds and provided a top speed of over 220 km/h. Such sporting high performance made it one of the world’s fastest series produced sedans, capable of standing shoulder to shoulder with such nimble sports cars as the Porsche 911 S or the Jaguar E-Type 4.2. The only clue as to car’s output was the discreet number combination 6.3, positioned to the right-hand side of the trunk lid, ordered by many customers for the "obsolete position."
