There’s no such thing as a hybrid. It’s a S 400 with 15 KW “Better starter electric motor” and start stop automatic is a hybrid. The V6 itself delivers 200kw – 13.33 times the electric motor (15 Kw). Average consumption 7.9 liters (Prius has a 50kw electric motor!) The W123 has 40 KW in 1977 and a 2.3KW starter motor. If I count it for 31 years of development retardation then I can call it a hybrid. Its engine has a 17.39 times the power of the electric motor! Its only manco: No start stop system (1977 not yet ready for production). Average consumption also around the 8 liters, but not the same acceleration values *g* Where is the big revolution. Both vehicles have a similar ratio – to an electric motor!
