Hello, I am considering purchasing a 99 E320. I have only ever previously driven 300 E type Mercedes.

I recently took a short test drive in an E320 I'm interested in, but I noticed when shifting it seems as if the engine power is reduced during each up shift and returns after the shift is complete. It otherwise seemed to shift smoothly. I could not tell, is there a feature that electronically reduces throttle during shifting, or is it something unusual?

I do not know which position the W/S switch was in, and I did not change it.

 

The 99 E320 does reduce the throttle in order to change gears. This decreases the amount of wear caused int the gearbox during shifting, and gives a smoother shift. The other thing which you may notice is that the engine revs more when the car is cold. This is to heat up the catalytic convertor quicker.

 

Thank you for the reply.
