Probably a really silly question, but will the car only 'select' to deliver full power when set into sport mode.
I ask because I recently had our SL350 with the M272 engine at GAD for a remap. They found the engine well down on power, but managed significant improvements during their remap. And well done them for that!
STAR produces no error codes. GAD, it their testing found a happy engine.
Now, in old codger mode, I know the car is more lazy, starts off in 2nd gear and changes gear much lower down the rev range. Also the engine/transmission electronics adapt over time to the normal driving style, which for me is generally quite relaxed!
Does anyone know if the MB engineers also decided that in Comfort mode the engine should have its output reduced, knowing that maximum power would probably never be called for, in order to improve longevity/reliability/economy/whatever.
I understand that for many years now some car engines switch off some cylinders either with light load or in certain other circumstances (eg slippery roads/ice etc) to better manage the situation as perceived by the car.
Does anyone know if the M272 engine in the SL350 is instructed by its management system to drop its output when in Comfort mode? Seems to me not to be beyond the bounds of possibility, particularly when you consider the current thrust of 'car manages driver' not 'driver controls car'
