I got my c350e in june, lastmonth. I just wanna share a little bit of my experience with this model.

First, the fully-charged battery normally can't last for 31km as told by the SA. It actually based on our driving behavior and mine last for about 22km for my driving behavior (which i got "horn" by others most of the time XD). The weird thing is, sometime u will just lost few Km upon your next start-up. Eg, before you shut off the vehicle, the display showed 15km left. Upon next start-up, it show 13km. In my opinion, this hybrid model is not as good as my expectation because i travel quite a distance/many places in a day.

Secondly, i felt tired in the sense of driving experience when the battery running low in hybrid-mode. Because the vehicle frequently switching between the combustion engine & electric drive and you need to well-control the gas pedal. Too soft on the gas pedal (still in electric drive with low battery condition), the car will move like turtle. Too hard on the gas pedal, sudden activation of combustion engine and "over" power supply, u will feel "choking" on d vehicle.

Thirdly, my c350e's transmission is terrible. In electric driving mode, i don't feel smoothness on the 2nd to 3rd gear transmission. If i switch to charging mode or R mode, which the combustion engine is always on, transmission up-shift always causes the RPM reaches 2000+, and down-swift always causes "jerking" feeling. Some said this my be the adaptive transmission problem, which can be solved by sending back to the center to do resetting. Well, i will send for checking regarding this matter soon, and update here again.

Anyways, although i had a not so good experience with my first Mercedes, still i love it so much.
