    ..."Obviously, we employ some specialized techniques to achieve such figures, but there's no reason why owners of TDI vehicles shouldn't be able to achieve great mileage," Gerdes says."...

    Indeed for me, I try different techniques, really to stay..... (amused) ....zzzzzzz

    Funny, the Prius was not on that player list ! ?

    That is funny. Would you want to drive a Prius 15 hours a day cross country??? They do best as taxi cabs in town.

    Now for me it is easy to imagine a sort of frankenstein Tiquan with the 3.0 L TDI with an 8 speed A/T or a beta test DSG 9/10 speed with the E288 upcoming 2015 TDI. (280# ft?) My guess here is a conventional 6/7 speed M/T would probably STILL do better.

    The Audi Q5 TDIs are posting some 32-34 MPG averages on Fuelly. May be the perfect choice for a showdown. The Q5 is offered in gas, gas/hybrid and diesel. The hybrid has a lower EPA rating than the diesel and costs $5k more. Also requires Premium Unleaded. If it is like the Touareg Hybrid the dealers are dumping them at below cost.

    For any number of reasons, that's (32/34 mpg) VERY good !!

    But here are a few reasons, given your post.

    1. the EPA is 20/28 mpg

    2. way cool given 4,079 #'s

    3. AWD vs 2 wd front

    4. 8 speed A/T vs 6 speed DSG

    Aka, 14.3% to 21.4% better H fuel mileage.

    While I do not know the exact toll 682 #'s more takes in a Q5 (4.079 #'s) vs Tiquan (3,397 #'s), I know there is at least SOME. Now IF I use the 1 mpg per 100#'s rule of thumb, THEN up to +/- 6 mpg.

    A safe swag would be +/- 3 mpg.

    The Q5 has the same drive train as the Q7, Touareg and Cayenne. With less weight than the others it should get better mileage.

    For real high mileage SUV the Tiguan 2.0 TDI is the future. Not sure I would down grade that far. BUT, who knows?

    Most diesel-hybrids on the market are trains, and they are not weak at all!

    My whole house shakes when one goes by, so I would say that NVH is still an issue there :)

    Trainspotters would agree that seeing and feeling a new diesel locomotive would give them a New Vehicle High. :)

    (Don't dare mention that you meant Noise, Vibration and Harshness).

    All I know is, I gotta take the Cruze diesel on her first long trip, to Utica, NY. I'm gunning for 55 mpg.

    Hahahahahha! Gotta love it. The hybrid's battery died while it was plugged in to charge the battery.
  • gagricegagrice San DiegoPosts: 28,676
    Bad enough worrying about one battery. But two to keep charged and happy is too much. I know all vehicles are complex today. Seems hybrids are off the chart complex. I guess I wouldn't try working on my T-Reg TDI, so it is not a real issue. I overhauled a lot of engines when I had to. I would not know where to start with today's vehicles.

    For in town use, wouldn't the hybrid beat the diesel? So for those city commuters it might work out better?

    Also, the entire point of the gas/electric is to allow the Atkinson cycle, using the electric to boost low RPM performance. That wouldn't be much use in a diesel application, since it already has plenty of power at low RPM.

    (I realize that the hybrid also has regenerative braking and shutdown at lights)

    Looks like Ford has reached their peak on the C-Max. Down 50% over November last year.

    ..."All I know is, I gotta take the Cruze diesel on her first long trip, to Utica, NY. I'm gunning for 55 mpg"...

    Fuelly.com shows 51 mpg to be an outlier (1 of 47), so it might be a tad optimistic. That being said....

    If it is anything like the VW TDI's, the computer is really calibrated to shift for best mpg (fastest upshift @ lowest rpm). So... firm but not lead foot acceleration and get to the LOWEST rpm with full torque. So for example on the VW TDI's that is 1,750 rpm. Now I do not know what speeds (the lowest rpm for full torque) that converts to in the Cruse TDI , so adjust according to comfort and feelings of safety levels. Lowest rpm @ full torque will be a great baseline (place to start).

    Now I do not normally follow my own advice, even as I know how to get between 62 to 59 mpg. I like to run it more at 2,100 to 2,300 rpm (usually higher, seems to be optimum for combined systems) But then, I am ok with only 48 to 52 mpg ! :) On the 09, I am fine with 42 to 44 mpg. :)

    VW TWIN UP ? diesel electric.

    The funny part is the environmentalists are literally choking off the (domestic) mining permits needed to mine needed materials to make lithium ion batteries, ah the very (storage of power) systems the environmentalist are saying is the kool- aid that will save the planet !! I bet NONE of us can guess the major reason WHY !! ?? :) You can't even MAKE this stuff UP !!! It appears the second coming of Christ (which most enviro cons don't believe in) will happen before (domestic) mines will happen.

    They are swaging 30 miles on 8.6 kWH consumption (almost laboratory conditions) . To me personally, this makes no sense till 200 to 300 miles per charge (even I know this is illusionary). FURTHER even if it gets there, @ what I have been mandated to pay per KWH , the electrical portion and cost per mile driven is way more than diesel (@ 50 mpg !! ) That is the good news !! I understand the utilities have applied for RATE increases !! (Surprised I am sure) Not to sound rosy, but the electrical grid is already at best unstable !! So closer to 214 mpg with diesel portion, electrical per mile drive is literally 450% more (than diesel) !!!!!!! It might raise the question, ...why bother ?

    I do understand they are probably counting on our collective math skills to drink the kook-aid !?

    The diesel is a figurative and literal putt putt @ 47 hp. Using current ratios, that is (a swagged)79 # ft of torque.

    Not to mention the World's largest reserves of Lithium is Bolivia. A country the US has screwed over and is rightly hated by them. So China will get the Lithium and we will get the over priced batteries. We have all but shut down resource development in this country.

    What amuses me is how people "suddenly" become environmentalists when someone proposes to dig a mine or put a factory up in their backyard.

    The other funny thing is how scared the electric utilities are running over solar. Ergo the rate increase proposals and regs to discourage people from hooking up to the grid so they can sell the excess to the utility.

    And another interesting trend is how corporate campuses in the suburbs are closing down and the HQ buildings are moving back to the urban core. The new crowd coming in has the coding savvy that the corporations need but they don't want a long commute and they don't want to work and live "in the sticks". Even the married ones with kids are starting to forgo the ranch house with a lawn and intend to stay in the city. (Yahoo)

    And when they have kids or get tired of the fumes, they'll be griping about lung cancer risks and demanding even cleaner public transit. (straight.com)

    Maybe solar powered Amazon freight drones will make the urban air cleaner.

    Lots of room in "CORE" Detroit !!! It even has a Democratic majority !!! ??? :) I had read in passing that of a former 144 sq mile city, 44 sq miles lies "fallow" on the tax rolls. This is not to mention the "arrested decay", or the building "products" that are marginally, to no longer really useful.

    There is even an interesting "crisis" in San Francisco, CA (the internet companies moving there, etc.) that if they do not cook the books politically will soon will have a 100,000 student body community college lose their accreditation.

    Of course, I am sure the City and County of SF, CA appreciates the various transit unions striking and threatening to strike every other week.

    Looks like the techies are tired of BART and its spoiled brat employees and are hiring their own shuttle services.

    The MTA clarified that shuttles conduct 35,000 rides per day, and individual people can complete more than one trip per day, so the number of total riders is lower), mainly from 200 established public Muni stops near their homes in the city to their offices located in more boring towns 40 or so miles south. Participating companies include Facebook, Google, Yahoo, Apple, Genentech, Intuit and eBay.

    The often enormous and unmarked big white buses have many haters in a gentrifying city where the median one-bedroom apartment now costs $2,795 per month, up 27 percent in just two years. The symbolism has gotten to the point where piñatas in the shape of Google shuttle buses were smashed at a recent public protest.

    Not many gassers/hybrid owners know what their cars gas consumption per hour rate @ idling, YET when a city structurally slows down traffic, to making it CRAWL to stop fully, the defacto condition is it increases gas/fuel use and massively decreases "productivity". The spin off nexus here is even more pollution.

    So for example I know ( the my two) diesels consume .2 gal per hour. So if (like model (128 oz x.2 gal = 25.6 oz. So on a 42 mpg normal =8.4 miles it COULD have gone vs ZERO.

    40% more (35.84 oz) on a (like model (27 mpg ) gasser could have been 7.56 miles vs zero. The net effect is gasser waste FAR more fuel idling than diesels.

    I think they would be TRASHED/VILIFIED whatever they chose to do or .... not. !!! ??? If they didn't do the shuttles, the vilification would probably be: these "TECHIE" jobs unfairly CLOG the already over worked and over crowded and dilapidated transit system/s. As if they REALLY don't want more jobs and want to get rid of jobs, TO lessen crowding on transit systems !! ???? Without prohibiting these private shuttles, the estimates are already a MINIUM of $ 20 B to rehabilitate the city's transit system, needless to say, they don't have those kinds of funds.
