2007 CR-V Fuel Economy

[wizzo]

I have a UK 2007 EX CTDI with safety pack and this is the first car that I have owned that actually returns( and often betters) the manufacturers fuel economy figures. I manage to return on average 45 mpg.(Combined).The manufacturers figure are 43.5(combined). How does everyone else get on?

My last car was a BMW 320D coupe and I should have been able to obtain 49 mpg(combined) but only averaged 39 mpg.

It is sure good to hear of such good mpg numbers when you don't even have the engine broke in. Is that Imperial gallons as well? If the diesel is like other Honda engines, run it hard to break it in right and fast. MPG usually goes up as the engine breaks in.

Post some pictures of your CR-V with some local-to-you scenery in the background. We have members all over the world.

I'm glad to hear it!

My Accord Tourer i-CTDi has an official 47.9 UK mpg, and I get about 45 mpg if driving carefully.

My diesel CRV should be delivered next week, so I can report back on it then!

When in 2009 we get them in US the MPG US is rated 36. We are all ready to buy these units, still don't have the correct diesel fuel at pumps yet. Let us know of your maintenance cost and frequencies. Give us your cost and your capacities and we will convert them to US prices and capacities. They are going to be in high demand in 2009. If you can tell us what your diesel fuel is rated at in sulfur parts per million,our new diesel is 15PPM. Our proposed cetane ratings are 55-60 in US.

Presently our Diesel is 50ppm but it is going down to 10ppm in 2009. Our Cetane rating varies from 50-55.The service is every 12000 miles. I don't know the cost yet as I have only done 5000 miles. I will speak to the dealer and let you know. We can only have 6 speed manual transmissions with the Diesel, will the US be getting Auto?
The diesel is a great unit, it pulls from 1300 rpm and does 0-60 in 10 secs yet will give you 40 mpg all day or 45mpg if driven carefully. Over in the UK we have Imperial Gallons.(ie 4.54 litres)

(I have a diesel pickup truck)

I just got my cr-v cdti last week and only getting 31mpg although mainly city driving.I am a bit disapointed but thinking it should improve. Still quite the difference.

Still quite the difference.You need to be patient until the engine is broke in. My diesel pickup truck took nearly 15k miles before the mileage improved measurably. Now I love it.

A US gallon is 3.785 liters, thus the British gallon in about 20% bigger (5 quarts vs 4 if I remember right). With less fuel per gallon, we will see lower MPG rates in the US with all other things being equal.

Yes I am aware that it should go up but will it realy go up as much as 10-15mpg. I do not rely care because I love the car to much but want to make sure it does what it says on the tin. Just to know what other diesels are getting. That fuel average instrument is well addictive to almost dangerous. I look at it so much that it spoils my enjoyment of driving this beauty.

Remember, too that Honda has designed (is designing) a NEW diesel engine for the US. We are not getting the identical European one.

That is quite a way of my figures! Mines only done 5000 miles so still not fully run in.

Mine is a company vehicle and I have lent it out to other staff. I reset the trip which also resets the mpg and when he came back it only returned 33.5 mpg. He is only young(I can't believe I said that as i'm only 39) and drives a petrol and tends to use the revs.

My Journey to work is very much a mixed bag with windy country lanes(which i love to iron out),town and Motorways(freeways i think in the US).

I have had a few diesel's now and use torque instead of revs and this gives great mpg. Is this your first diesel? It could be your driving style or you may have a problem with your vehice. I would leave it at least another 2000 miles just to get used to the vehicle. Let us know how you get on!

[wizzo]

one other thing I should point out is my vehicle is fitted with the safety pack(as per signiture) and this has a great cruise control that has a radar that detects the speed of the car infront and keeps you at a safe distance and will even break for you if the other car slows down,but then accelerate if it speed up. I find this an absolute gem of system as you can use the torque of the engine with very few gear changes. I Regularly get 42-46 mpg

This weekend trird driving differrently and got better milage.It is my first diesel and it seems to want to be driven like petrol a bit more umph and then cruise.Thanks for your coments and please do tell how I should drive. It seems to want to cruise at 1500rpm for best economy. I am waiting for first 700 miles to go by so that I can push it a bit. It seems to like being driven a bit rather then just cruised. I also felt a little pull on the left as some other drivers in other threads. I will soon contact honda .Do not no wather to go to dealer or honda uk first.

I've had my car less than a week now, but finally had a chance to drive it a bit at the weekend.

On a 34 mile round trip I averaged 46 UK mpg (38 US mpg) according to the trip computer.
Conditions were:
- there and back on the same road
- twisty A road, mostly 60 mph limit, with some 30 mph villages. Some very steep hills (i.e. 2nd gear) and a few hair pin bends (Banbury to Stratford road for Brits).
- starting with a warm engine

Not bad I thought!

The automatics that will be used in the US diesel powered Honda's are being designed and built just for these new(US) engines. No word yet of the number of foward gears, but hopefully at least four like the gasoline engines since 2006. The problems of the right shift down at the right RPM propably can be modified by reflashing if they at first don't get it right. I read they have a transmission factory, in high gear, making them already in the State of Georgia. Word here is we will see a 4 & a 6 cylinder diesel. The V-6 will be put in the Ridgeline pick-up, the Pilot and the Accord. Then the Accord will be Hybrided for a speedy model with high MPG's. No word of any CRV hybrid diesel electrics yet. They might do it though as demand will be there, and the competition may force them to, as word is there will be Diesel electric SUV's here soon (2009). We are staying at 15 PPM (ULSD) as a study states it is the lowest level that still gives economic to producing the fuel. The cetane is 55-60. Our bio Diesel is going no where as recent studies show there is no cost benifit in making it, as it takes more energy to make it than it gives back (concluded by Cornell Professor David Pimentel) and others. The December 3, 2007 average cost for diesel in US is $3.47 & Gasoline $3.09 with prices trending down as reported by the US DOE Survey of thousands of pump prices from cost to coast of the 48 States. California is highest South Carolina, and Maryland are lowest.

Now I have about 900 miles on my diesel CR-V, I can average 40 UK mpg = 33 US mpg over a tank with about 30% town driving.

Fortunately (because I got 45 mpg from my Accord Tourer) we have just bought a second car for mainly town use, a 2004 Honda Civic Hybrid. It is averaging about 50 UK mpg = 42 US mpg.
