x1 poor gas mileage

[fpm14]

Anyone been experiencing poor gas mileage on their X1? Just traded in my wife's 2007 Suszuku Grand Vitara which was a little heavy on gas. Read all the reports on the new X1 having great performance for a turbo 4cylinder with great gas mileage. YES, performance is incredible but gas mileage is AWFUL for a 4 cylinder engine. They advertise 6L/100km and I am not even close to that even with highway driving. The Suzuki got about 450km to a 60liter tank and the X1 is getting about 500Km to a tank full. Add to that, the increase cost of 91octane and I am spending twice as much on gas as I did before. By comparison, my Audi A5 3.2l, which has been 'performance tweaked' to add another 75 horsepower gets about 600km to the tank and that's with me pushing it. I'm about to trade this x1 back in !!!!! Terribly disappointed.

I am getting about 9km/litre for my first tank. Should have better mileage with subsequent tanks. Considered reasonable to me for a 1.5tonner.

How can 10% more range from the same 60litres be costing you twice as much?


I get 44mpg from my 18d sDrive, which is around 6.5l/100km.

There is no way a petrol will get that, I would guess around 8-10l/100km average.

The official figures are....

Fuel consumption
City (L/100km) 10.2
Highway (L/100 km) 6.5
Combined (L/100 km) 8.5
Tank capacity in I (approx.) 63


Higway figure is pretty unachievable on any car, it is done on a warm engine, no aircon etc. on, and at really slow average speeds.

I always look at city and combined and think city will be close to my average and combined what I get on a run, this has been about right for my last 20 cars.

The double cost for gas may be a slight exaggeration but taking into account the older Suzuki took regular gas, and the X1 takes 91 Octane at considerably higher cost per liter. I've had the car for 5 tank fulls now and have only 2300 kms on it. That works out to pathetic gas mileage.

First of all, "The Canadian advertise 6l/100 km" is based on tests that are run in a closed garage and on a lift with only the front wheels spinning on some kind of "dyno". City tests are done at speed under 50 km/h and highway between 70 and 97 Km/h.

The cars are not touching the ground at all and the weight factor is out of the equation. So, those measures are bullshit till they change those tests to put the cars on the ground and go for a real roadtest ( road being important here !!!)

You should take the city mileage of any reported "official" mileage in the window sticker, add 1-2 litres and take this number as your "combined" mileage. You should be on target with this tip.

I'm averaging 12 l / 100 km mostly city driving and my X1 is 4300 km ... you have to take into consideration the cold weather. You should do a lot better when the engine will be broken and the weather over 10 celcius.

Just take a look at the l/100 km needle and you will see that each time you are on an acceleration or you go through some climbing ( even the lightest ) the mileage is suffering because of the weight factor. As someone on this site wrote to me about that : Don't sweat it ! Enjoy it !

fpm14 - you really should be using at least 95-octane fuel or higher on your X1 - performance and economy will improve too.

[Jhopet14]

Yes. I notice. I am from Sk, Canada. Gas mileage sucks.

[jackinbc]

I have over 10,000 KM on my X1. Gas consumption averages 8.9 L/100KM over the 10K. I drive about 80% highway. If I drive 100% highway I will get about 7.9, and 100% city gives about 11. Yes, it is a 4 cyclinder but it's a 245 HP engine - regardless of the number of cylinders if you use the full performance that is available your gas consumption will be affected. I typically drive "spirited" so my mileage is probably worse that what is achievable. I usually go about 600KM per tank. Sounds like 450KM per 60L tank on your Suzuki is pretty similar to 500KM per 63 litre tank on the X1 - with the X1 being about 6% better. So if you are driving the same sort of highway/city split, and driving in the same manner, your X1 is getting 6% better mileage and with premium about 15% more than regular - that's a total of about 10% higher cost which is a long, long ways from double!

It is also not really fair to compare a run-in car with a new car that has only 2000+ KMs on it. The engine takes some time to run-in and loosen up (less friction).

Give it some time. It will get better as you clock more miles on it.

[CanadianDriver]

just to put some perspective, my stock N52 engine is about 2L/100km higher (give or take) than what you guys are getting. in the end, all of your are saving a bit at the pumps, have more hp and torque... isn't that nice

fpm14,

I drive an 18sdrive.. initially i was disappointed with fuel consumption averaging close to 15l/100km. After 6,000km, the average consumption has dropped to below 11l/100km. I have read many similar posts here..

Give it some time, im sure it will improve considerably after your engine has been run in.

He is probably talking about 91 AKI rating, you must be talking about RON rating. Two different ways of calculating octane - AKI being the North American way & RON being the RoW/European way.

The following page is very interesting - the section I am linking to directly compares fuel ratings across countries - Petro-Canada's Ultra 94 is quite surprising compared to others: http://en.wikipedia.org/wiki/Octane_...octane_ratings

There are so many factors when considering and attempting to obtain the best fuel economy out of a car. First, the fuel. All late model BMWs that aren't diesel will adapt to available fuels. That means that if you put a lower octane product in the car, you will get less performance and most likely a slight reduction in economy. In the US, BMW recommends using fuel from top fuel providers, including Shell and Chevron. These companies have additives in their high end fuel that help keep injectors clean, protect the engine and improve lubrication. You should always use the highest octane fuel available, even if it is $.50/gallon more, for ten gallons you are spending $5 extra in a tank, a Starbucks coffee and snack to get more performance out of your car.

Next, driving habits. If you really want good economy, drive like and Eastern European. (not meant to be an insult) this means light pressure on the accelerator and shifting to the next higher gear as quickly as is practical. This works better with a diesel or a car with a turbo, but my 128i cabrio can do quite well in the city if I drive in Prius mode. On the highway, stay n the highest gear and even use cruise control to maintain a steady speed.

Lastly, breakin certainly affects performance and economy. My car is getting faster and more efficient now that it has passed 10,000 miles. BMWs only get better!

[Blue Bottle]

Agree about all above just passed 2000 Miles now and got 48.5 MPG on a long run home, Diesel was best option to get good MPG.

"Drive like an Eastern European"?

LOL

In my experience Eastern Europeans, nor in fact pretty much any Europeans, are known for frugal driving.

We like going fast occasionally too... Except our governments do their best to stop that sort of behavior - THINK OF THE CHILDREN!!!!

11.3L/100km right now... usually dropping .1 on each 200km round trip on the highway. But it's that high to begin with due to a lot of short city driving trips.

Pure HWY trips at 120km/h were around 8.5

Problem is (depends on where you live, but in the GTA) people drive 120 'minimum' on the highway. That's going to be 20% worse fuel economy out of the box. US cars I think are tuned to 55mph... which we are not driving here along the Trans Canada, across the country. Even Atlantic Canada's main highways are now 110km/h limits (which they drive, but that's still above the testing conditions).

This was all painfully obvious to me when I had an 08 Honda Fit and was not getting anywhere near the 6.5 combined. I was lucky on a pure hwy trip to get below 8 until I hit up cottage country (twisty roads with 70/80km/h limits) where I was probably averaging about 90km/h and suddenly I hit a high 6.

Blame modern multi-lane highways like the 407 where you can set the cruise and not worry about traffic. It's a pay off, your time for your fuel economy.
