Hi Folks.. my 2 month old QX60 AWD Gas model fuel economy is no where near the promised numbers. I get an AVG of 11 MPG City/ 14 MPG HWY.

I have driven a total of 550 Miles.. I have tried all the modes .(eco/std/sport) just does not seem to matter.

Also the vehicle seems sluggish...I had a chance to drive a demo QX60, that was much better than my new car.

Any thoughts?

The transmission will adjust over time because it is electric, and you will see a boost in gas mileage. Gas mileage is all going to depend on how you drive, so if you drive aggressively, you obviously will get worse gas mileage. There should be no difference in feel between two different QX60's, unless you have a hybrid. I would give it another 1000 miles or so, and if you do not see a jump, then take it into your dealer. Hope this helps!

You will get better milage on your new car. It needs to break in. I have almost 34K on the JX and typically get 21-24.5 mpg highway, and 19 mpg around town.

I too was getting 12-13 mpg in the first 2 months and it has improved over time. I am getting about 24 mpg now at about 7000 miles. Either the car has adapted to my driving habit or my driving habit has adapted to the car. Having the mpg status on the display helps too.

Thanks for your replies guys.. lets hope it gets better with time!

Also do you guys have a take on premium vs regular fuel? I have never tried it yet.

I have been switching off between Premium, Mid-Grade and Regular an haven't really noticed any difference in milage and performance. I do try to stick with Premium however.

I find the mileage is sensitive to how you drive the car and your average speed (I have a 2014 gas/AWD).

I keep track of my mileage on a spreadsheet and have found the following:

  • My actual average fuel economy is 12.3 L/100 km (19.1 mpg (US)) - calculated by my spreadsheet, not the vehicle
  • The vehicle's calculations overstates the fuel economy by about 5% on average (vehicle says my mileage is better than it really is)
  • The mileage is affected by average driving speed (see attachment - note red circles = car's calculated mileage, blue diamonds = actual). Most of my driving is to/from the office, and while it is about 70% on 2 lane - 6 lane highway at good speeds, the 5 km closet to the office is horrendous with lots of lights and delays and thus really kills.
  • My mileage since early-mid January has become noticeably worse. This drop is coincident with installing the roof cross bars on the vehicle + consistently extremely cold (below normal) temperatures in Toronto (and seems to have snowed most days). More likely I think due to the temperatures and snowy roads than the cross-bars

I only use regular grade gasoline - the price differential between regular and premium in Canada is something like C$0.15/litre or roughly C$0.60/US gallon and what I understand to be a minor improvement in fuel economy does not warrant paying more for the gasoline.

I try to drive the vehicle very "gently" to keep my fuel economy decent (e.g, slow steady acceleration). Anecdotally if I drive my car normally without thinking about going easy on the gas, then I think my mileage gets worse by about 1 L/100 km, give or take. I can only imagine how much worse that would be if I was to drive aggressively.

I have had the vehicle since July 2014, just under 14,000 km on the odometer.

I've never reset the mpg reading on the monitor since the day I purchased my QX60 AWD vehicle. I hadn't taken any long road trips, so my driving is pretty much a combination of highway, and stop and start around town. After 12,000 miles, my monitor was reading 20.7 mpg. I went on my first long road trip (1300 miles) this past week, and the monitor is now reading 20.9 mph. The one in the DASH, which was accidentally reset recently, is reading 22.9. So the dash reading is showing mostly highway driving. I am pleased with the results as I do have a pretty heavy foot. I do use premium gas because the engine in this car has the same sports engine used in the previous G35's. I've driven G35's for 8 years, and find my QX60 is getting even better gas mileage inspite of it's heavy weight. I guess we can credit that to the CVT transmission, and thank goodness to date I've had no problems with that. Oh, what a great riding vehicle for the long trip!! :)

Ya same here - I have an 06 M35x and the QX60 uses up to 20% less fuel on some days.
