    Oh-slight aside
    Recent AOL news "article"
    Said TCO greatly favored buying the TD version of various cars
    VW buyers save about $3900 to $5100 over 5 years of ownership
    Pricer brands MB Audi- even bigger savings.
    Much of the savings is in lower depreciation-higher resale.
    And pricy car buyers-do dump their cars earlier than most folks
    So these are real savings-

    It didn't compare them to a Prius of course-
    and I didn't see Chevy's TD little cars compared to the Prius-it is more or less DEAD right?
    Shame-buyers liked driving it.Easy 50 mpg at highways speeds according to one owner I was following(before it was totaled-drunk driver-but saved its occupants despite 2-3 360's rollover at speed- 10 or so airbags and crush zones-decent roof-WORKED
    2 occupants scrambled out-just bruises cuts sore as heck
    Yeah shame about Chevy's TD Cruise (which I can never spell)


    The fancy high performance Audi-AWD- 40 mpg at 70 mph-impressive-bet that is a 3800-4000 lb car-probably accelerates faster than 95% of muscle car era muscle cars.(low bar very very few of them did under 7 second 0-60- too little tire too much rear end too little gearing-and the HP was rated differently-optimistically-back then)

    40 mpg at 70 mph- 4X what a muscle car would get.

    It's Cruze, Charlie. And I think it's a decent highway car. City , or even the "city/suburban" driving I do , the Prius will spank the Cruze.

    And while the diesel cars we can get here usually offer a lot more engine than "we" want, in Europe they sell super-high-performance diesels that would totally impress American gearheads.

    Yeah the Prius is the WHY bother answer to many small eco type cars
    WHY bother to try to import and sell a TD small economy car?
    The Prius is very reliable cheapish and beats all of them FE wise
    so all manufacturers have to ask-WHY bother we can't beat the Prius
    (I have always been suspicious that Toyota is selling them for little to no profit??)
    Probably just my paranoia.
    It just seems soooo good-at least our 2006 does-for just $22,850 OTD after TC-
    Not a hell of a lot more than a civic or a corolla...


    Those Euro TDs are kinda cool-heck even that somewhat oddball VW V10? V-12 TD 500 ft lbs-was kinda cool- waaaay overpriced-and repairing it-pricy
    But if I won the lottery-it might have made it to Phoebeisis Estates


    CRUZE huh-not cruise like it "should be"
    never could spell

    I tried to cobble together some steady state runs but the data was too anomalous. Cruise control would have helped too.

    Hi All:

    2014 Toyota Corolla LE ECO Speed vs. FE

    [​IMG]

    The 2014 Toyota Corolla LE ECO w/ 16" wheels 40 mpg highway rating crossover occurred at 71.2 mph with linear.

    The CVT allowed a very reasonable 1,610 RPM@60 mph which correlates well with the 1,591 RPM@60 mph calculated.

    Wow 51 mpg 60 mph-almost Prius territory
    And 71 mph getting EPA hy !!
    How much does that Corolla MSRP for??
    Much cheaper than a PRIUS?
    Prius still 15 or so mpg better city?

    Yah, I'd like to contribute some for the new Note, but suffer from a relative local lack of exactly flat stretches that are in decent condition, that I can either go fast enough or slow enough on. There's a piece or two of highway, but then I have to do a 3 mile or so loop to get back onto them for each run.

    I've got cruise, and it can be engaged at 30mph, but understand the issue of trying to keep your foot steady if the road is at all uneven or has the odd bump.

    I'd like to see that for the Note.

    I put Wayne's (and Andrew's in his Fit's case) steady-speed data for interesting cars of the past year or two into a spreadsheet, which makes them easier for me to compare.

    Hi Charlie,

    Yes they are getting really close to Prius numbers. I get around 53-54 mpg at 65 mph.
    If you compare the Prius chart and Corolla chart the difference really isn't that much.
    MSRP is probably in the $5,000 -$6,500 range between the two. The Prius will stomp it in the city but if you drove mostly highway the Corolla Eco would be the car to chose.

    I'll try and get some I'm confident about on the Note then, at the moment I'll tease you with an educated spitball of 54mpg at 60 and 51mpg at 65mph. This is with onboard gauge though.

    Edit: could be as high as 62 at 50mph also... will be checking.

    Thanks. IF those numbers hold up under closer scrutiny, they're impressive---splitting the difference between Prius numbers and the Corolla LE ECO CVT. I'm guessing the on-board gauge is significantly optimistic.

    Yeah-that is pretty decent-great really!
    $6000 difference?
    But the Prius is discounted heavily "some places"??
    So maybe closer than $6000??

    Thus far, the average consumption looks 4% optimistic, but not sure how it's handling idle, if 4% of my gas was wasted waiting at lights and intersections and it records only "moving" fuel consumption then it could be dead on.

    I have also not callibrated the speedo/odo against anything else yet, I have a suspicion it's reading 2% low. Due to my Escort Wagon being "dead nuts on" according to GPS and a few miles of mile markers.. and pacing the trucks which have a 105kph limiter finds them dead on 105... pacing a couple of trucks in the Note found them at 103 indicated.

    edit: Oh, suspicion that it doesn't affect average from idling arises from being surprised my av didn't rise from a very long wait in traffic one day (at least 7 mins, but untimed) and also on returning from gas station after reset last time, I idled a minute in the driveway expecting it would change drastically as I idled because it was only based on 3km... but nope, stayed same.

    Hi All:

    The 40/39/40 mpgUS city/highway/combined rated 2014 Toyota Avalon Hybrid Limited Speed vs Fuel Economy results.

    [​IMG]

    Using linear analysis, the EPA Highway crossover occurred at 70.8 mph.

    The speedometer was ~ 1.5 mph over reporting vs. GPS while the CC and digital speedometer were right on with the GPS. Strange?

    47 mpg at 60 mph-
    in a big comfortable car like that
    and 40 mpg at 70 MPH- 4000 lb 190" near LUX car
    Who needs a MB TD when you get Toyota reliability and better FE for less $$?
    I know you guys LOVE TDs so I have to cheap shot them whenever possible!

    Hmmm probably not cheap- how much for the Avalon hybrid-$50,000??
    I don't shop new cars anymore,so might be OFF on prices.

    Hi Charlie:

    Watch the video and read the 2014 Toyota Avalon Hybrid Review. :)

    The 24/38/29 rated 14 A6 TDI is more expensive for sure. Marian beat the 40/39/40 Avalon Hybrid by 1 to 2 mpg on her back and forth to work commute in the uber powerful AWD German machine somehow?

    Hmmmm
    So very close FE wise-with a slight node to the Hybrid because of the diesel premium.
    But since Toyota somehow manages to scrub ALL the fun out of their cars before releasing them- the Audi would certainly win on fun factor.

    I still have trouble accepting diesel costing MORE than premium.
    For most of my life it was generally a tiny bit less than regular- a penny or two

    Hi All:

    The Mazda MX-5 Miata Club’s Speed vs. FE appears pretty good for its very low 28 mpgUS highway rating.

    [​IMG]

    The reason why is that its 28 mpg crossover occurs around 75.5 mph (calculated linearly) which should give it more along the lines of a 30 or 31 mpg highway rating.

    RPM@60 mph was still a very high 2,710 RPM but close to the calculated 2,678 RPM@60 mph (circumference, not revs/mile).

    See , if they actually rated it at 30 or more highway MPG , the geezers who buy these things would suspect it was "slow". At 28 MPG, it's still "sporty".

    Should convertibles have different highway ratings top up vs down? Just
    wondering if tests have been done to compare.

    Thanks,
