I filled up for the first time tonight. The car had 305 miles on it and a "full" tank when I left the dealer. I'm guessing they didn't top it off. I reset the trip computer when I pulled out and hand-calculated 50.2 MPG. The fuel-computer says I got 52.5 MPG over 661.2 miles. Crazy thing is the fuel computer thought I had another 68 miles left in the tank. I added 13.2 gallons. I think the tank only holds 13.7.

In any case, it looks like these cars are easily going to hit 50+ MPG and live up to the EPA-estimated 700-mile range.:happy:

For those that are really into this kind of thing, the DIC has three rolling averages for fuel economy: Last 25, 50, and 450 miles. It also remembers the highest average achieved for each distance. I have 64.5, 58.7, and 54.4 as "bests" for 25, 50, and 450 respectively. Given the right conditions, it looks like these cars could average 60+ on a tank. I think it's too hilly where I live to do that well, but it's nice to see what the car can sustain over more than just a few miles.

That's just amazing. If I did my head maths right, that's about 1/4 cup of fuel to go a mile. I probably drink more water than that to walk a mile, let alone run.

Well, good to know they live up to that very high EPA number - I'm at the very low end of the mileage rating on my 1.4T. I'm curious as to how close the autos will get to theirs - considering how efficient it is in your MT, I'm thinking they'll overshoot their EPA MPG like the 2.0D did as well.

Being a diesel, it's almost guaranteed they'll surpass the EPA rating.

Awesome!

The best I got with my 1.4T manual LT was 48.4 mpg over 719.3 miles and used 14.9 gallons of 93. It took some extremely thought out planning and very careful, stressful driving to get that. My lifetime average is 32.6 mpg though.

Conclusion: By my calculation, that new 1.6T diesel is going to average far better mpgs over its lifetime than my gen 1 gasser.

Is your gen 2 diesel manual or an automatic transmission?

I believe it is a manual.

Your right...his dic display would have auto stop if automatic, his doesn't have that.

Thanks for the update. That's very promising! Interesting they changed the 3rd average to 450 instead of 500.

Darn, now I'll have to really work at regaining my single tank champ status (51 MPG - 2012 ECO MT).

That's excellent news for the new diesel.

I've done high 40's and 50 once for a short while (80 miles), but I REALLY had to work at it.

I bet if you tried to hypermile that once the engine's broken in a bit more, the results would be 60+.

It's almost all highway miles. The DIC average says about 45 MPH. The first 100 miles were interstate at 70+ with 4 passengers and the A/C running. Since then it's been my commute, which is all rural highway (55-70 MPH limits with a few traffic lights) and interstate highway.

I've been watching fuelly to see how the gen 2 diesel's do.. None on there yet .. My lifetime average for my 2014 is just under 50 mpg for 120,000 miles.. If the gen 2 gets 10% better it might be good enough to offset the smaller fuel tank and still get me over 800 miles on a tank.. I don't like filling up more than once a week lol

Good to know. I'll keep watching fuelly and this thread. Thanks

It looks like you're posting about a gen 1 gas, not a gen 2 diesel.

Indeed. Been meaning to move them.
