Yes, exactly. Yesterday on a very flat stretch, with a warmed-up vehicle, running for 10+ km, 350 m elevation, tires aired up over 40 psi, no traffic, no notable weather/wind, #2 petrodiesel, empty vehicle, half tank of fuel, cruise control set to 104 kph, I was seeing 9 to 10+ L/100km (call it 23 to 26 mpg). The EVIC display never once dropped to 8 L/100km over that stretch.

Now, maybe it was doing a regen, but that's fairly par for the course in my experience. In terms of having it checked out, my experience with dealers is that if there is no MIL lit they just tell you it's operating normally, and I have nothing to point to as overtly malfunctioning. It seems like the extra energy would show up someplace if this were the case, friction losses causing abnormally high heat readings, mechanical sounds, something.

The only way I got higher values on the rest of the run was using ACC (set to 1 bar following distance) to draft tractor trailers the entire time. So, not a real comparison, but a nice hypermiling application for ACC nonetheless. The adage about the view never changing if you aren't the lead dog definitely applies, though.

Re: Max MPG? Hypermiling the Diesel JGC

Hypermiling by using ACC to draft big rigs. Hey, now there's a great idea.

I now have 9K on mine and did a recent drive to Vegas by way of San Luis Obispo, from San Jose. I didn't hypermile it, and drove pretty fast - at 80-100mph most of the way. Still got about 24-25mpg.

Man, do I love this car.

Drafting one is fine, but ideally you're between two tractor trailers in order to maximize the slipstream effect. It would be really taxing to draft reliably and safely without ACC, because the truckers let their speed vary considerably when they encounter hills.

Every time a truck passes the one I'm drafting, I "upgrade"... it's fairly difficult for me to tolerate going 65 mph, but a lot of these trucks go even slower than that.
