2016 C63AMG Fuel Economy Warning
Discussion
Having previously owned a M156 C63 AMG and now recently purchased a 2016 C63 AMG Saloon, I can tell you that any advertised fuel economy improvements, just do not exist.
It is so bad that I have recently had the car in at the local dealer for an assessment of the fuel economy and they confirm it is fine. They did confirm to me, that they tested it at 50 in a 70mph road and also 40-45mph on a 60mph road. Not what I would call real world conditions. My wife drives the car into work with no air con and in pretty mobile traffic with few stop/starts and can not get past 15 mpg. I recently drove from Edinburgh to Aberdeen (around 120 miles on mostly motorway and could only get 24.7 mpg. I drove the journey with no stereo or air-con, with VERY conscious use of the accelerator at around 70mph. This same journey with everything on and no conscious effort on fuel economy could easily gain 26 mpg.
The majority of the time, the car gets 9.4 to 13 mpg (in comfort mode). To me, that is just absolutely astonishing and unreasonable for a car of it's type. Yes it is a powerful car, but it is also advertised as a family car with extra urban figures of 42.2 mpg. Urban figures sitting at 26.2 mpg.

Interesting... I'm actually seeing the opposite, I had a 2009 c63 a few years back and no matter how I drove it I either got a bit less or a bit more than 20mpg (like 19 -22). I've now got a C63S estate and over 15k imiles I've seen 28mpg on a longish run (Derbyshire to North Wales), 26 following the flow of traffic on a 45 mile daily dual carriageway commute and low 20's driven more enthusiastically on the same commuting run.
I must admit it seems to have dropped 1or 2 mpg now the weather has got cold,...?
But this is my every day car so I rarely take it out just for a drive and on the occasions I have, I've no idea what it did to the gallon...

I can see how the new motor might not be a whole lot more fuel efficient than the old 6.2 but I would not expect it to be so much worse!! Your observations are even more significant given that you have owned both the W204 and W205 C63 so something does not stack up.
I was reminded of a tale of woe from another C63S owner over on one of the US sites. He had issues with extremely premature break pad wear - something like 2 sets of pads in no time at all on an untracked car. Predictably MB could not fault the car and blamed it on driving style. However there was some discussion on the forum that this sort of unexplained brake wear had been seen with cars where the traction/stability control set up was wrong and the car was running with constant brake "drag". In the end I think he gave up on the car and got rid of it, but would be very interesting to see what sort of fuel consumption this fellow had been getting.

I do a lot of miles in my 2016 C63, mainly motorway, and I'm getting over 25mpg average. That's about half and hour on the motorway at about 80mph with half an hour of queuing in town as well. I wouldn't say I was gentle with the throttle, using full throttle at least once per journey.

Cold weather means more dense air, which means more fuel can be burned with it. This means more power but also worse mpg. This effect is especially prevalent in forced induction cars. Notice the car feels more sprightly in cold weather?I must admit it seems to have dropped 1or 2 mpg now the weather has got cold,...?

I've got a 15 plate C63 Saloon with the 4.0 V8 and i'm managing to get late teens around town and I am not driving it economically at all. On longer runs (Aberdeen to Edin for example) i've seen 28/29 and when I was running the car in I got 31.1 for the journey between Glasgow and Aberdeen so the cars can do it.
I also did the NC500 in the car in the summer and over 862 miles the car averaged 52mph and 13.8mpg. I can assure you that economy was furthest from my thoughts as I kept up with 675LT, Murci, 911 Turbo S and various other supercars.
So, to sum up, you either have a duffer or drive with a heavier right foot than you think.
btw, on the motorway runs I set cruise at 77 and leave it.

28 vs 24. In terms of cost on a run from Aberdeen to Glasgow how much does that actually matter. £45 vs £50 if that.
Not just the cost of fuel but having to stop and fill up more often.As part of the overall cost of ownership, fuel smaller than most imagine, but its something we all see daily, unlike maintenance, tax, insurance, depreciation...

Good excuse to stock up on in car snacks. I'd just enjoy the car and not worry. As part of the overall cost of ownership, fuel smaller than most imagine, but its something we all see daily, unlike maintenance, tax, insurance, depreciation...

hi guys,
new to this so bear with me.
I am potentially considering a 2016/17 C63 amg, but the only thing that is swaying my decision will be the ''15mpg'' I've seen people get from this.
I do a mixture of motorway/city driving for work so this will be my daily.
I just wanted to know if anyones getting mid 20's driving in a mixed mode- comfort most times but open to giving it some when the roads open up a bit,
any response greatly appreciated!

Had my C63S for nearly 2 years now and I have to note that I am in the US, so gallons are smaller and the fuel here in California isnt great!
That said, if I drive it around town / local stuff, I get a pretty consistent 18MPG. If I am only doing shorter drives (think 2-3 miles short trips) then that drops to around 15-16MPG. However, if I am driving out to Sacramento airport (not going to happen for a while!) which is a 50 minute drive on what would be A roads and a few smaller sections of motorway, I get a solid 22-24MPG depending on how much traffic. Speeds vary, but thats 60-70 on the A roads and up to 75-80 on the freeway sections.
On a recent trip to the mountains I saw something like 23MPG going up and 28MPG coming down! I am genuinely surprised as to the economy and its WAY better than the 958 Cayenne 4.8S that it replaced! Could it be better? Sure, but my wifes 2016 Malibu (2.0T) struggled to get better than 26MPG and we only saw 28MPG on a steady run! Then there was the 2004 Mini Cooper we had that was solid low 20's all day, every day! And dont even ask about my wife's current Evoque, which is dire!
So yeah, not great, and could do better. But for the power, performance and instant response, I am rather happy with it. My fuel bill went down when I switched, so thats a win!

What fuel do you guys have over there? 91 RON? My W204 6.2 litre says to use at least 98 RON but I feed mine 99. 95 is the standard ultra low sulphur unleaded here.
I had a 3 hour hoon on Sunday and averaged 16mpg. Loved every minute of it too! 28 mpg obeying speed limits on long steady motorway runs on cruise control.
