    I would consider spending tax dollars to expand natural gas lines, and help home owners with heating oil to convert, a worthy use of funds. I know some people north of me and in western Pa still use coal for home heating.

    Except for maybe the smallest of refineries, heating oil is now ULSD in the US. So is the fuel sold for off road use. I think all diesel sold in Pennsylvania is now B2 for those of interest.

    I've heard the GREET model has an entry for a biomass to diesel method that is carbon negative. Don't know how close that is to reaching market though.

    Telling how little news or rumour there is to report, that this thread has evolved to "the future of diesel". ;)

    Hmm, I suppose Americans (and Canadians too, as we always follow our neighbours) will be getting even heavier. Got to eat many more fries to create enough used cooking oil to power all those "new diesels". ;)

    What's the expression, when there's a lull in a lecture: "Talk among yourselves..." lol.

    Well British gallons have 5 quarts.
    But the major difference test procedures are different.

    there's no gas in our town. the houses are few and far apart. i suppose it would be prohibitive without subsidies. we have propane, but that's as expensive as oil.

    British gallons have four quarts or 8pints (pint = 0.5 quarts). We buy beer in pints, petrol in ltrs, and calculate our cars economy in miles per gallon. When we buy a measured length of anything carpet, timber, tubing we buy in mtrs, but road signs, and speed limits are in yds, miles, and miles per hour. It is still possible to buy a yard of ale (beer).

    Geothermal heat pumps with solar would be best in areas with the houses spread out.
    We live in town, on a main road, and didn't know there was a natural gasline right front of our house until we were getting estimates for a new boiler.
    A friend lives in a typical housing development which doesn't have gas service. He is using bioblends now.

    funny, my last house had gas in the street, but darned if the gas company knew it. i had to jump through hoops to get it installed. in this house, we keep getting 'switch to gas' promo letters, but i can't find evidence of lines, and when i call, they tell me it's just a blanket letter.

    Well......that's not quite accurate either.
    The table that Google provided said a British Gallon is 4.54 liters or 4.79 quarts.

    I always thought that a "metric gallon" was 4 liters. Guess not.

    Yes the UK gallon is 4.54 ltrs, but it is 4 quarts or 8 pints (2 pints to a quart) these are imperial measures. We also have gills (4 gills to a pint), firkins = 9 gallons, 4 firkins = barrel, and 52.5 gallons = a hogshead. A gallon of water is defined as 10 lbs of water at 62f.

    Good news everyone!

    The fuel economy for the updated Auris hybrid are in! This gives us an idea og the improvement in fuel economy for Prius following the European fuel economy norm. This is slightly less optimistic than the Japan norm, but still widely optimistic compared to the EPA.

    OK. Time to crunch some numbers.

    Auris Hybrid was initially released in 2010 with the 3G Prius drivetrain. The numbers back then were:
    Prius: 25.6km/l or 60.2mpg
    Auris: 26.3km/l or 61.9mpg

    The new Auris to be released after Summer 2015:
    Auris: 28.6km/l or 67.3mpg

    In other words: 8.7% improvement in fuel economy.

    It sounds like 8-10% is realistic for the next generation of Prius. Bear in mind, though. I do not know if the updated Auris is going to use the G3 or G4 drivetrain.

    @PriQ , what changed for 2015 in the Auris regarding the powertrain that resulted in fuel economy increases?

    From the looks of it the new Auris has the G3 powertrain complete with 1.8L ICE and 101kW of power combined. I mean it has a couple of more Hp and an extra kW of horsepower but nothing earth shattering (more likely a difference in emission controls than in the US). Toyota was aiming for lowered emissions.

    so imperial pint has 20oz, not 16 as God and Founding Fathers intended??

    how about beer bottles, still 12oz, no? or they come in pints?

    either that or different battery as electric output is limited by draw

    Unfortunately I don't have any information other than what you can find on the net, which is sparse at best. For all I know, my best guess is that they continue with the G3 powertrain.

    There's much more information on the new 1.2 turbo and heavily upgraded 1.4 diesel. The increase in fuel economy for these two engines is far more impressive (the 1.2 turbo is compared to the old 1.33 and 1.6).

    I find comments on the size of pints, quarts etc. to be rather funny. It is -Imperial- originally, meaning English, or now British. THEY set the standard, the US just wanted to "do their own thing", probably to rip off the public. ;) A -gallon- is 160 oz, not the smaller size the US uses. ;) And just to throw a wrench into the works, I -think- the fluid ounce is also slightly different, though I haven't been able to find definitive proof of that (they hide the facts well). I no longer care, as we use metric here in Canada. Nobody has had the gall to change the sizes of the units in that system (yet).

    Actually, the US was, and could be said still is, following the original British system. The Imperial system wasn't standardized until 1824. Being no longer part of the Empire, the US simply stuck with the British units they had been using before.

    The gallon originated in Britain, but there actually three different ones; one dry, and 2 liquid. The liquid ones started for measuring beer and wine, with one for each commodity. The US gallon is just the wine gallon. The ale gallon was larger and became the basis for the Imperial gallon, but they aren't exactly the same size.

    The fluid ounce is slightly different in each system.

    The metric system is so easy. Use it at work, but I still think in standard for temperatures and day to day stuff.

    On the other hand, reading on the Toyota news site, the new Auris also has a wishbone rear suspension so it should ride better and handle better than the current gen III. Or it may be a sign of things to come.

    Alright, thanks!

    The 1.33 is already replaced? The 1.33 and 1.6 litres, aren't they the NR family of engines?

    Excellent.
