Last night I forgot to plug it in, so two trips to contrast. One out of London to home fully charged 25 miles, 18 miles electric only, 7 miles petrol, 2.1l/100kms (135mpg)

Driving in this morning, 10% starting point so an experiment, charge mode from home to around 18 miles, raised enough charge to cover the 7 miles into central London, 6.8l/100kms (42mpg)

What's interesting is that this car easily achieves the manufacturers figures for my 25 mile trip which includes a good 7-10 miles at 70mph and a load of central London congestion bits.

Just over 8,000miles in my C350e.

On my 22 mile b-road commute driving at the speedlimit, the car does over 100mpg when leaving fully charged and 40-45mpg when leaving with 10-15% charge.

The MPG without charging seems to be around 40-45mpg which i think is very impressive for the size of car and performance.

The pure electric range (c12miles) is largely irrelevant as on journeys over this it manages so much more distance with the engine off ie my 22 mile commute is normally 17miles with the engine turned off.

6months in and i am still very impressed with the car. I expected compromises for the BIK tax benefits over say a 330d/335d but i genuinely can't find (m)any.

Small fuel tank, hassle plugging in, annoyingly juddery due to engine switching off and on when driving, braking being somewhat jerky, heavy, poor mpg on long journeys.

But, reasonably quick, good for company car tax, contemporary, silent when on electric

Time of the month Jonah?

Agree about the braking though.

Small fuel tank - bigger than the competition at 50ltr. For my use the car does the same mileage per tank as my previous E91 335d. Bigger tank would be nice but not if it compromised battery capacity or boot space. I think they have it about right. I have started charging twice per day and range will be 500-600miles so significantly more than the E91 335d which would do 450-500miles mixed driving.

Hassle plugging in - no hassle if you have a tethered charge point

Annoyingly juddery due to engine switching off and on when driving - Seriously, have you driven one? The seamless transition between ic and elec is one of the most impressive parts of the car.

Braking being somewhat jerky - granted the regen braking when coming to a stop takes some adjusting to. It could be better but isn't a problem. I rarely notice a jerky stop now and many people drive standard cars worse all the time by not easing off when close to stopping.

Heavy - According to Parkers it is 120kg heavier than C250d, 90KG more than a C43. Doesn't sound too bad. Granted it doesn't handle like an E91 3 series, but then again it doesn't ride like one which is good!! Can't say i notice the extra 60kg of weight over my previous E91 335D

Poor mpg on long journeys - Compared to a 2.0ltr diesel yes but it has the performance of a 6cyl 3.0ltr diesel. It is comparable to a 330/335d in both performance and economy even when not charged.

But, reasonably quick, good for company car tax, contemporary, silent when on electric - yes.

I'm almost certainly going for one of these as my next company car, given that the BIK makes this sort of car a no brainer and the waiting list is too long on the 330e.

I just came on to ask if anyone had calculated how much it costs to charge it up vs running it without plugging it in.

Given the huge fuel savings I'm likely to make during the week running the kids around and the like it sounds like it's a bit of a moot point, but I'd still be interested to know if anyone has figured out how much it costs to charge it from scratch on a typical home electricity tariff?

Also, I noticed the comment about poor MPG on long journeys. What sort of mpg should I expect on a hundred mile motorway run?

It will cost you about £1 max to charge.

Excellent! That compares nicely to the fiver or so I'd currently spend on fuel... smile

The few long journeys I've done have been high 30s, low 40s.

I would agree no charge economy is c40mpg - still impressive for the size of car and performance.

Battery capacity is 6.2kwh and it will rarely let you drop below 10% so max charge is going to be c5.5kwh ie c£0.60 per charge (my current tariff is 10.338p+5%VAT)

I just filled up on the way to work this morning - 700.4miles on a tank of petrol, 44.29l, ie 71.85mpg - new record for full tank average.

Economy on these cars is very dependent on journey profile. I now charge both at home and work and my 22mile e/w commute is 17miles engine off. Most trips into town at the weekend are purely electric.
