Hello there!

I know these are cold days in canada, and can consumption can go high with my snow tires, but I noticed a 21L/100km on city and 13L/100 on highway with my XC60 t6 AWD 2010.

this car drinks a lot.... did you notice this kind of high consumtion on 2010 T6 models ?

 

I get 15.5 mpg and 19.5 mpg (city / hwy) on 2003 xc90 t6 awd.

19 cty and 24 hwy on 2005 xc70 t5 awd.

had a 2001 v70 and got 22 29 mpg.

Basically, large cars have more weight (reduces cty) and large surface area (reduces hwy). AWD systems reduces mpg by 2-3 mpg. Turbos with heavy footed drivers can reduce by another 2-4 mpg. Every time I stomp on the xc90, it drops by 2 mpg.

Tires can take another toll, reducing another 1-2 mpg. Cold weather (long warm up times, engine doesn't run efficient when cold) can reduce mpg 1-2 mpg.

Driving above the rated speed will sometimes reduce mpg, but the relationship in proportional to the square of velocity. i.e. mpg at 80 mph will be (65/80)^2 less. This is the basic physics of drag, but some car engines are more efficient at the higher rpm, so may be about half of that penalty.

So take a look at your driving habits, add up the numbers above, and let us know how you come out!

Cheers, J

 

So I did the conversion, you are getting 11 and 18 mpg

 

wow I am suprised you have a better consumption with a heavier car! I was sure XC90 would use more gas.

I will wait for spring to make a better comparison, but looks like this XC60 is a heavy drinker, even without pressing the turbo...

 

My 2010 XC60 T6 AWD is a gas guzzler. In Atlanta's traffic it's a good $60 a week. Ouch!

 

Hi there,
My 2011 xc60 was a heavy gas drinker for a bit. I broke her habit by replacing the screws around her air filter housing. My gas milage got better. It created a better seal. Maybe this might help you.

 

Haha I hope thats a joke

 

Will the air mass filter increase the efficiency
