The reason Merc's engines are tuned/designed to have so much torque is that it fits their luxurious character.
Torque moves a large heavy car away from a stop light with little effort...which feels 'luxurious.' Makes the driver feel powerful b/c there is so much reserve.
That's why past Bentley/Rolls used slow revving 6.7 liter engines with insanely low redlines and have a power reserve gauge on the dash...they want you to know how little their engines are working ("Out of my way peasant!!").
This charactersitic is why BMWs inline-6 is so loved. It's one half of a V12....perfectly balanced and it feels rich with torque, yet nimble. This makes the TT 6 so incredible...it's never 'off cam.' A racing clydesdale if there was such a thing.
This is the hey dey of the modern combustion engine. Drive em' while we got em'
Still not a good idea to try and out pull a Merc with a 63 or 55 on the back
