    Latest road trip - finally saw 25 MPG on one tankful

    Just returned from a 2000-mile round trip from Spokane, WA to southern Utah in a 2011 3.0 XWD. Tires were 39 PSI cold and usually 41 on the road.

    When the car was new, it averaged around 20-22 on the highway. Now with 15,000 on the odometer, this trip was 23.7 MPG and one tank in areas with lower speed limits was 25. Most of the rest of the time was 75-80 MPH on cruise control through the mountains.

    One fact I ascertained is using the air conditioning definitely costs at least one MPG. Naturally, on a hot day, it's worth the cost many times over. However, on this trip, the daytime temps were 50-60. On the way down, I didn't think about turning off the AC. MPG was 22.5. Today, same road with AC off, the average was 23.7.

    Interesting data...

    I'm just amazed at how much better gas mileage I'm getting on my 2nd Gen SRX (2010 MY) compared to my last SRX (1st Gen 2005 MY). I haven't crunched the numbers yet, but I'm sure I'm going many more days/weeks without needing to fuel. That's been a pleasant surprise I wasn't expecting.

    A member who shall remain anonymous PM'd me and said it must be my heavy foot, as he gets much better fuel mileage.

    Turns out, he has a FWD, which naturally is going to get better mileage than an XWD.

    He did admit his wife will not let him pass on a two lane road or exceed the posted limit. A built in economy czar is bound to help.

    DId you have the A/C or heater on at all? What was your tire pressure. I assume the road was mostly level.

    I had the HVAC system set to Auto, the A/C was running the whole trip, but it wasn't super-hot so it never ran very hard. Went from North GA to middle OH, so I saw a fair amount of mountains.

    Now.... I will say this, I was flying solo on this trip and only had one small suitcase with a few days worth of clothes, my laptop, etc - so I had a mostly empty vehicle.

    I was just impressed I was getting this kinda of MPG running at 75 Mph. In previous vehicles it always seemed that if you wanted to get close to the rated highway MPG you had to do about 55-60 Mph, so I am pleased.

    Anyone have any opinion of the penalty for all-wheel versus front wheel drive. My experience is at least one MPG less, maybe two MPG. davedog saw 25.4 with FWD. I got 23.7 with all-wheel under similar conditions.

    I hadn't noticed FWD in his sig. That will make a difference.

    Fill up with Ethanol free gas...you'll get 25 or close to it everytime.

    Re: Latest road trip - finally saw 25 MPG on one tankful

    New 2013 SRX AWD. 1200kms since new.
    Recent road trip to the coast and back over the Rockies:
    Total Trip: 4240 kms (2635 miles)
    Average Economy: 12L/100km (19.7 US MPG)
    Average Speed: 81.7 kph (50 Mph)

    Maintaining a healthy 136 kph (84.5 mph) [with an 80 km/h headwind both ways!!) highway speed on the flats and 121-130 kph in the mountains (too many RVs, semis and poor drivers to go faster). Also, my Adaptive Cruise won't work on even numbered kms. Anybody else with this issue? I only get about 20 mins out of it before "Adaptive Cruise is Temporarily Unavailable" for two minutes before being able to reactivate.
    When you turn your car on, does it return the favour? '14 Cadillac ATS Performance 3.6L AWD in Phantom Grey Metallic and Morello Red Interior -ARRIVED!!

    Latest road trip to/from Missoula, MT. 2011 3.0 XWD - Steady 75 MPH most times and 22.7 MPG.

    Maybe it's just mine, but the cruise control drops a couple of MPH before it opens the throttle. I've had several cars recently which seem to maintain exactly the speed setting.

    Jack, I noticed the same thing. My old SRX (2005) would hold the set speed at all costs (RPM & otherwise), and on the new one it seems to be 'smarter' about how it maintains the set speed. This sometimes results in being a couple MPH below the set speed for a bit, but it also gets MUCH better MPG than my previous SRX.

    I have noticed that when resuming cruise, if the actual speed is even 1 mph below the set speed and you press resume, there is a jerk and excessive rev. If you get speed above the set point, it's a smooth transition from foot on the pedal to cruise. Very annoying.
