80kmh is 50 mph so I wouldn't expect it to be in 8th, 90kmh won't activate it. On the interstate at cruzing speed 60- 70mph it should kick in.

Never had issues at interstate speed 90km/h plus being in 8th.
it should certainly kick in for interstate.

Akfan probably meant that it underestimates. The larger the tank, usually the more extreme its off. Like w/ a 32 gallon Ram, when it says predicts 0 miles (it won't actually go that close, it just stops displaying an estimate but you can calculate by looking at your trip meter from earlier estimate), it still has another 4 gallons or so left in the tank.

I think they do this because when modern cars actually run out of gas they don't really give warning and just instantly die and you lose power steering and/or brakes, so they tell you that you're empty long before you truly are.

SC has been very consistent when I fuel up when DTE shows 0. From my experience, Honda, Toyota and Hyundai usually allow for 70 to 90km or range when DTE shown at zero

Did a road trip this weekend. Traveling East to West in the high plains at 69mph I got 33.8 mpg with my turbo. Going South to North going up into the mountains at 75-80mpg I got 27.3 mpg.

I'll report what the reverse trip is tomorrow.

Edit

On the way back down I average 30mpg (high of 38 at one point). Going West to East I got 25ish but that was with a 30kt quartering head wind. Average was 28.

On my Ultimate/Limited, using paddles, 6th to 7th can be performed at 71km/h, if left to auto its nearer 80, 7th to 8 can be manually shifted (paddle blip) at 84/km/h, left to auto its over 90 km/h Typical road for me (80% of my daily drive) is 80km/h +5, If I relied solely on auto I'd be in 7th gear and 1800 RPM, with the paddle shift l can be speed limit +/- and below 1500rpm in 8th.(still feeling sporty, not lugging, Auto will push it to 7th if there is an incline )
Same trip, same direction, same speeds, using ACC with the wife diving the SC, it averages 26-28 MPG, I average nearer 32, difference? I ride the paddle shifter to 8th/1500 rpm, she's at 17-1800 rpm, as she's not comfortable, with the shifter or the paddles, always driven an auto shift.

I haven't seen anything close to that, you must have had the wind in your favor, or my foot just has a little more lead installed in it.

I had a quartering headwind of about 15kts going East to West. I was pleasantly surprised.

my range showed 20 miles today after I left work and I was only able to put 15 gallons in. 2.7 gallons/15% is a pretty big reserve.

Depends on the mileage you were getting: 2 gallons could be 30 miles or 60 miles of range. Sitting still at a traffic light your getting 0 MPG which makes the calculation go even lower. Due to the shape of the tank and location of the fuel pickup its possible that last 1/2 gallon isn't really accessible. As @JASmith said OEMs tend to be conservative with the DTE calculation so people don't run the tank dry.

I just did a 2500 KM trip from Toronto to New Brunswick. I averaged around 10l/100 km, I did not try to do anything to improve gas, some points near the end it improved to 9.6. I averaged between 110 and 125 KPH
