New method for figuring City/Hwy Mpg

You know that looks about right for winter driving, I guess they got to show the worst you can get.

Was thinking the same thing. Mine does that easily, even when my mileage tanks as temps approach zero and with some extra traction weight in the tail.

Yep...it will be interesting to see the "new numbers" in ads for the 2008s :arrow:

KenJennings · **Posted:** Fri Feb 23, 2007 11:06 pm

The new numbers are pretty much what I get now. For the first 10K miles the CRD was doing worse.

The city rating is more realistic. My folks never got 22 mpg in pure city driving.

Highway is another story. 24 mpg at 75-85 on the highway on I-90 from central WA to Missoula, Montana in 35-40 degree temps. To hit 23 we'd probably have to keep it over 80 the whole time.

What I am looking forward to is seeing ratings on the hybrids for 08. The ratings on those have always been very unrealistic and have made the argument for diesel adoption more difficult than it needs to be.

I wonder if the "new numbers" are because most of our dang odometers are off by 10%.

Hybrid MPG ratings for 2008 by old & new method:

Toyota Prius:

2001 Gen 1:

Old: 52 mpg city/45 mpg hwy
New: 42 city/41 hwy

But compare with the 2001 Jetta TDI 5-speed manual:

Old: 42/49
New: 35/44

The hybrid's new figures are more realistic (older figures were way optimistic), but the TDI's new figures are ridiculously low. How fast must you have to drive an A4 Jetta TDI manual to get only 44 mpg on the highway?

That highway figure seems pretty on par with what I used to get with my 03 Golf TDI with a 5 spd. I rarely got over 44 or 45 mpg highway. I know lots of people commonly reach 49 mpg or higher, though. I would say the city figures are low. I could drive that car like a racecar and never get under 40 the whole time I had it. I take that back, I did get under 40 mpg once when I was towing a camper. :lol:

Why did I ever get rid of that car?!?

Heck, I thought the Jetta I checked out this summer before I bought the Libby said 41 mpg highway. It was a nice rig but the dealer was a pig and wanted full sticker price ($25,000+). It's still on their lot and the sticker price went up another $1000. And they wonder why we hate car dealers. Lucky for me, I don't get bored easily and it's fun to see how far you can make your stinky diesel go. Car dealers hate me too. :twisted:

My 99.5 A4 Jetta tdi AVERAGED 49.6 for 114,000 miles. Highest was two tanks in the low 70's :shock:

Only one tank in the thirties and it was 39

Before that my 96 Passat tdi wagon averaged 45.9 MPG over 107,000 miles. My 06 CRD is averaging 19 mpg ALL SHORT CITY and that's almost double what my 99 Cherokee averaed :roll:

The 2004+ Pumpe Duse (more power) TDIs got poorer fuel economy than the 2003 and earlier models. I used an early-model TDI to illustrate the drop in EPA fuel economy ratings.

CRuD Bucket · **Posted:** Sun Feb 25, 2007 9:21 am

BTW, I averaged mid-high 40's in my 97 Passat TDI with an Upsolute chip. I could burn rubber going into 3rd gear and still get kickass economy.

My 200k mi 99.5 A4 Jetta TDI (manual) is often over 48-49mpg, never gets below 44 mph, even in the winter. I bought it this summer to add to our diesel fleet as my daily driver (I do play games coasting it, though). The thing is also a hell of a lot of fun to drive, so I beat it like a moonshiner with the sheriff on his tail. One day I averaged over 90 mph through medium hilly roads to NYC, did some city driving, and burned back and still got 45 mpg. However, I do not know what mods have been done to it (other than my EHM). The EGR and intake manifold were very clean, so I can only suspect someone knew what they were doing with it.

The new VW TDI's are even MORE sporty, but the mileage is worse for sure AND they are more finicky about cold biofuels with the high-pressure pumps. I test drove a few (gas a diesel) and they are very pretty on the inside.... but pricey and a but more dowdy on the body style. And the dealers are parting with the TDI's dearly... definite bump up in price for last years models!.

The libby CRD does fine at 22mpg with my lead-foot wife driving it around town, 20-21mpg in winter.

The new system will definitely favor diesels, which know how to pull their loads in real life.

I wouldn't say poorer mpg, I would say lower mpg. My 06 Jetta TDI with DSG averaged between 42-44 mpg overall. Lowest avg. mpg was 38 and the highest was 51.5 on a trip back from florida to maryland. I almost made it all the way back on 1 tank...if my mpg would have been 53, I would have been able to make it all the way back without stopping for fuel. This was before ULSD was implemented though. BTW...my TDI was wrecked and totalled with about 9,600 miles on the clock.

Like most posts so far, my CRD tended to get better highway and worst city MPG than the original EPA estimates. We got ~19 MPG city, but we have no long waits at rush hour since we are in a more rural mountainous area). On longer trips we got ~26 MPG traveling ~75 MPH. With living in the Blue Ridge mountains, the torque actually works to our advantage on the steeper inclines since the RPMs remain lower than our gasoline vehicles.

I drive almost all highway and I have yet to get better than 24MPG's

no-blue-screen · **Posted:** Sun Feb 25, 2007 11:25 pm

My best so far has been 25 mpg....normal average is between 22 and 24 mpg per tank. Worst milage ever came with a fill on Shell ULSD and that was 20 mpg. I suppose I may be able to raise this if I increase my tire pressure to 40 psi. Right now, I am running at 36 psi.

I've averaged a steady 21-23mpg for my normal driving. Good chunk of that is stuck in the crawl that is I405 in the Seattle area. That said, on the occasions when I've taken trips up and down I5 I have averaged anywhere from 29-31mpg, I even got 600 miles on a tank once.
