    I don't mind rotaries. They're pretty cool. I can't stand the sound though.

    rotaries have plenty of draw backs. all the power is at the top. even if you baby it, youll be lucky to get 20mpg out of one. they blow seals a lot.

    The wheels are that small so you don't have so much room wasted for wheel arches where you could fit loads of stuff in the back.
    (And if you wonder why the new Dodge transporters look so European, that's because they just took a Fiat Ducato, put a new badge onto it and made the lights ugly. Don't know how they managed that though.) EDIT: That was already said, I just wanted to point it out once more. I think they did that with a Mercedes Sprinter too, though.

    @amarks240 Their biggest problem is that they wear out. After I think it was 10,000km, you have to go check the engine. Otherwise the sealing (I don't know a better word) will wear out and the engine will misfire, which will damage the whole sytem.

    it's not 10000km, but seals don't last long in a wankel engine no

    they are fun as hell dont get me wrong. spinning an engine to 10k rpm is very satisfying, but my little honda will do that too without blowing seals. as a concept i love rotary engines, but in practice its hard to keep them alive.

    Do you still remind the number? I've heard it in a video where the RX-8 got reviewed, but I forgot it.
    @amarks240 Yeah, they are quite expensive to hold alive, although the good side about them is, even on extremely low revs, you have a mass of torque.

    Oh, if anyone is much enough into hooning and revving wankels to spend a few minutes, right here:

    i took a ride in an rx8 and it had almost no low end power. it did pull pretty nice up top however.

    Alright? That's the exact opposite of what I heard about the advantages of wankels in bikes. I guess I should do some more research right now.

    the advantage is horsepower per liter. they make a ton of power way up. stock that rx8 will spin at least 9200 rpm and actually make power right up to the rev limiter.

    he's right. Wankels are not the torquiest engines, but they do rev forever. The rev limit of a wankel is essentially a case of how long does it take to burn the fuel and can it be burned before the exhaust port is uncovered.
    usable power right upto the redline but not really masses of torque. They do take nicely to a nice low inertia turbo though which can aid the low end torque considerably.

    bigger issues are emissions and fuel economy. Plus materials issues in wear

    Those sounds from that car are... a bit disorienting to start. Also, why bother?

    Finally, it sounds a lot slower than it is (probably due to the long gears combined with buzzy sound).

    I bought a new dashcam for the holidays. It's a Vantrue R2. It records in 2304x1294 resolution and has built in GPS. I haven't had the chance to test it out on the road yet, but it should be a great upgrade from my G1W-H. I'll be reusing my old dashcam in another car.

    I averaged 14.5 mpg on my last tank of gas.

    Jesus, How aggressively do you drive? A very aggressive week for me is about 19mpg in the Grand Marquis. A good week is 22mpg. I average 20.5.

    I've never before thought of that USA doesn't have new wagons anymore.. and now it feels weird since in my country (Finland) I see wagons everyday, and not only from Germany;

    Volvo V40, V50, V70
    Hyundai i30, i40
    Toyota Corolla, Avensis
    Mazda 6
    Peugeot 308, 508
    Citroen C5
    Skoda Octavia

    We have now ~ 80 000 used cars for sale

    ~ 70 000 of those have body type notified:
    Wagons: ~ 20 000
    Sedans: ~ 17 000
    Hatchbacks: ~ 16 000
    SUVs: ~ 6 500
    Minivans: ~ 5 500
    Coupes: ~ 3 000
    Cabriolets: ~ 1 000

    So, most cars here are wagons.


    Model year 2014-2016 ~ 10 000 used cars for sale

    Wagons: 2 800
    Sedans: 1 000
    Hatchbacks: 3 600
    SUVs: 1 300
    Minivans: 700
    Coupes: 100
    Cabriolets: 40

    Seems like new cars have most hatchbacks..

    I myself have a sedan, I like sedans most :)

    How can I calculate mpg to l/100 km?

    Well, the big problem in this calculation is that MPGs are a negative scale, so if your car zips less fuel, you get a higher number.
    Or maybe l/100km is the negative scale, it depends on what you normally use.
