C350e owners club

To those asking about mpg there are several batches of post in here with various performances.

As a recap for my personal results...
29k miles
43.x computer mpg
38.x when you include charge costs
I do a mix of short country commute and a fair chunk of motorway and only charging at home
 
Picture of the information on my car, 350e Sport

These are the pressures for the 17" wheels, does anyone have the pressures for their C350e AMG with the 19" wheels?
 
For the record...
12 months
13k miles
44.1 mpg
Mostly 70 mile journeys with a charge at the start

Get a charger at work next month. Will be interesting to see how that effects the mpg over the 2 year

Driving tends to be 80% motorway. 90% sedate, 10% S/S+

Overall - still very much like the car. Active cruise is great on motorways. It's all very comfortable and refined. Luckily don't need much boot space. And can live with the various hybrid oddities. Next car will be 100% electric.
 
I'm averaging around 70-75mpg so far after 1yr, 3 months of ownership.

It's a good car for those doing mostly short journeys with the occasional long ones. I have a 19.5 mile commute each way, in the winter I only get 7-10 miles engine off but in the summer it's often 15-17 miles engine off....but summer appears to be missing currently.....feel free to let me know if you find it.....

I personally don't feel it works that well for anyone doing a lot of motorway miles, the 250d or 300h would be better for that.

I have twice returned to my car and found the boot wide open in the last month. On neither occasion did I use the boot when I parked the car, and the mirrors were folded in. Am I going mad? Is anyone else questioning if the shut the boot when they left the car? With regard to electric range, I have a 16A Charge master unit. When charged the car shows 16 miles, but in Comfort I only get 12 miles before the engine cuts in. My home town is surrounded by hills so not ideal for electric range. I have found that switching the HVAC off makes a difference.

This has happened to me once. I am sure that I locked the car as usual. The car was parked across the road from my house and well out of range of the remote control (which I tried). The mirrors were folded in and the doors were locked. My vehicle is going in for its first service next week so I will talk to the dealer about it, but I'm not holding my breath.
 
Mine was delivered Sept 2015. The socket was changed under a recall and done with the annual service in Sept 2016. I would expect all 2016 cars to have been changed - if it hasn't then you can get it done as a recall. I didn't have any problems with the original.



My car hasn't had the update to include the outside temperature - it's been in twice for it and the upgrade 'failed' due to a problem with the link to Deutschland.



Mine was updated on the third attempt! First at service was only a part SW download so didn't add OAT. Second one failed during download stage - why they don't download to a laptop first I don't know - third attempt success and now I wonder if it was really worth it! Also had connector changed at first service with no issues beforehand.

Thank you all for your responses.
I have booked my car in to have the low perceived battery range investigated. Have to say I expect to be told that my car is as it should be. It happens that the charging connector lamps no longer functions, just a single red light instead of the red /green/orange array I saw when the car was new so if that is corrected I will have not wasted the entire time it is in the garage.

As for range etc I don’t know if it is as it should be or not. This morning the App told me at the end of charge the battery would have a range of 16 miles. In fact at the end of charge it showers 15 miles. I got in the car and low and behold the display showed 14 miles. I am quite sure when I set off within a few metres the range will have dropped to 13 miles.

I can get an electric journey, a regular one of 11/12 miles on the battery when I am told the range is 13 miles and have sometimes have 1 mile range left.
Also the fact is that my average consumption since reset, several months ago, is displayed att 58.9 mpg. Certainly any other Petrol car with the comfort and luxury of mine would be challenged to better or even match that.

Since reset I have covered 2595 miles and in that period the engine has been off for 1820 miles. Brilliant I Here you say. Truth is I don’t cover 5000 miles per annum and I DRIVE AS IF I HAD MISS DAISY IN THE BACK !
Truly in order to achieve those numbers I have driven the car in the way a competitor in an economy run with a prize of £1 million would.

I like most people on here two years or so ago whilst waiting for my car to be delivered read every test, review and report. Watched endless videos on YouTube and the one consumption number that I remember very plainly, I can hear many of you shouting 18 Miles mpg. Yes that was the number and even today it still crops up.

Never have I seen a review that talks of a range in the real world conditions of just 11/12 miles.

As for battery degradation mentioned above I am reluctant to accept that because Tesla owners have produced statistics to show that it is not a factor that concerns them.

My neighbour visited me to say my boot was open and I know it wasn’t when I left the car.
I discovered that it was opened by me by simply leaving the key fob in my trousers pocket and leaning up against a low wall whilst leaning over to recover a ball. Plainly the release button was depressed at a time when the fob was still in range of the car.
 
Friend of mine was forever opening all the windows on his Lexus with the exact same trick. He finally learned to not put his key in his pocket, after having the interior soaked.

Had an 'interesting' one today. Just back from a gentle trip out of about 15 miles. Plugged the car in to charge. About 20 minutes after doing so, I happened to notice that no significant power was going into the house (recently had a Tesla Powerful/Solar PV system installed so I'm a bit obsessive about monitoring it at the moment). Checked the MB app, it reported a 'charge malfunction'. Car showed a red battery icon on the charge socket. Unlocked car, removed charge cable, re-inserted it, charging recommenced. Still going OK now.

This is with a Rolec 7kW charger by the way, charge limited to 1.9kW by settings in the car by me.

Hopefully not a sign of problems on the horizon.

I Have experienced a malfunction from time to time.
I now habitually check the app after connecting to a Chargemaster etc point. So often I have checked and needed to move the car to an adjacent point and then all is well.
I have a Rolec Charger and on occasion the trip at the top has required resetting for no apparent reason. Again, same as the Chargemaster episodes, once reset all is well. Might be connected to my car connection and if it is I hope that Mercedes will correct it at the end of the month when it is scheduled to go in for investigation.
 
On the subject of electric miles ...

Did 16 miles today on B roads on electric only. ICE kicked in about 200 yards from home, nearly made it all the way. Had it in hybrid most of the time, put it in E-MODE when it indicated down to 3 mile range left to eke the last drops out of it. I was pretty darn pleased with that.

On the other hand, like jimshann, I started one day this week with an indicated 16 mile range that then dropped to 14 before I reached the end of the drive. Which is about 5 car lengths - I'm not Lord Blank with a 2 mile avenue through my estate.

Anyone grumbling about the official figures should go and have a read of the EU fuel efficiency testing procedure. It's hilarious. Done on a rolling road with no wind resistance and incredibly slow acceleration rates. No wonder nobody ever gets close to those figures in real life.

Still loving driving mine and reading about all yours!

Just stumbled over this post and would be glad if you would tell me what issue you had with the connector which required a recall.
I have an issue with mine, only one red light instead of the original three when connector is inserted.

I had no recall notification !
I did get told of a recall for a fuse investigation which amounted to nothing. I wouldn’t have learned about that if I hadn’t taken it in for a tyre problem.

In Feb I sent an email saying that it had been said in this forum that the rear wiring loom was a recall and the service manager confirmed - "A recent service measure has been released to update the charging socket wiring loom to the New current specification". He told me the upgrade was to take it up to the same spec as on the new E350e. They did the replacement in a day.

Thanks for that, most helpful.
I am saddened that I had to learn about it ,as did you, from a forum.
Really disappointed :(

My car has been charged roughly 700-800 times since I got it and I haven't noticed any serious degradation...the battery packs are made by Tesla I believe.

Mine was just past the water ingress cable loom problem so never had that.

I have noticed that my electric starting range showing is much less than it used to be (always says more in the app than the car too!) but I then don't notice any different "engine off" miles on my regular journeys.
 
Lots of discussion about battery performance currently. I get the impression from comments the batteries are holding up pretty well and have a feeling that these cars are going to have a lot more miles in them than conventional cars as the whole drivetrain system is generally less stressed. Admittedly there will be exceptions to this hypothesis due to the complexity of the system, i.e. any of us might get unlucky. Anyhow 17,000 miles so far with the ICE engine only on for only 8,500 of those miles. 19 miles was never realistic as Joe points out in his recent post above.
 
Just a thought - I am not good at checking tyre pressures and I wonder if there is an optimum pressure for mpg. I realise of course that pressures will, when off, impact mpg but by how much or little ?
I presume a higher pressure would be beneficial but is that right or wrong ?

I accept that 19 miles was a figure that would be hard to better but I do remember some of the early main reviews were written around the experience of journalists in San Francisco and the figure of eighteen miles per gallon was reported frequently as the expected consumption. Given that UK gallons would provide a higher number, around 23, it is surprising that Mercedes went along with it. Dishonest is the word that comes to mind :(

It's another one of those automotive trade offs, a higher pressure would infact reduce the rolling resistance but the trade of is that there's less contact meaning less grip and because the contact patch is smaller, the wear rate is higher.
Of course, the rate at which this affects your tyres and fuel economy is infinately variable dependent on driving style, weather, road surface, steering input, acceleration and braking forces. The weight of the car, the distribution of that weight, the list goes on.
In a nutshell, because we are not in an F1 car, I'd suggest that if the pressures are as indicated in the fuel filler cap, or a few psi either way, you'll be ok [emoji106]
