The switch is surprisingly easy I found! Being allowed to turn right at a red light is kinda nice too, plus very few roundabouts. There's precisely none in Yellowknife.

Im not sure whether I like slushboxes or not. I think they're nice on big engined cars but it's just a waste of time on a lot of europes cars. As you know our fuel prices often force the issue of efficient cars, that blue one of mine has a tiny engine and an auto on that would be naff.

Noooo , I Like roundabouts and the right side : P . Id do it if I had to but it wouldn't be by choice , took me long enough to get used to it as its is .

1 litre. One of these new generation three cylinder jobbies. Looked it up and it has also been used as a fire engine water pump or something like that? Whatever it is they're said to be pretty good, although typical of all three cyls they're really rough at low rpm and have no power whatsoever until 2-3k rpm where it all surges in like a turbo

Ah ok , I heard they can be good , from what I know they are in the lower end road tax bracket . My peugeot 208 uses a three cylinder turbo 1.2 litre petrol

Re: Post your random pics!

I pay 20 quid because I didn't opt for the bluemotion version, otherwise it would have been free. VW have just launched a TSI version, the same motor with a turbo bolted on producing an impressive 90bhp, although longevity may be a concern some years down the line it looks like a solid motor. I think they have been sensible in not offering a diesel, the intended use of these cars (city, short run) is totally contrary to the strengths of diesel despite several other marques going down that route.

In keeping with the thread subject, here's a pic I took on one of my recent trips to Amsterdam, one of several yank mobiles I saw while there:

There's a surprising amount over there, possibly because its easier than in the UK due to driving position and perhaps cheaper fuel costs. I daren't think how big the engine is in that and it probably weighs as much as the moon!

The only American cars I've really seen in the UK is the odd old import or the two Crown Vics that sit on Glasgow Byres Road. Otherwise American cars here are next to non existent. The comfort and respectable motorway mileage must make for great tourers, but the fuel costs here would make owning one otherwise prohibitive.

Stick is definitely more fun to drive, automatic is just more convenient I find. Engine size isn't an issue over here ... most vehicles have large engines, even my 89 corolla had a 1.6L straight 4. Buddies ford focus has a 2.2L straight 4.

Oh yeah, I forgot they were going three cylinder now for these small vehicles. That must be really good on gas, your wallet must be thanking you. I'm currently getting around 8-9MPG around town with my 4.7L V8, hopefully bring it up a couple MPG with some maintenance (Spark plugs, transfer case, front diff oil change, that sorta thing.).

Re: Post your random pics!

8-9 MPG?! Jesus H Christ, that is literally unaffordable over here.

Not long ago I seriously considered buying and importing a Crown Victoria to the UK, and driving it. Ive liked them for ages and at one point I swore I'd do it when I had the money. I have the money, and it turns out to be something that, when I thought about it, I really couldn't do. The fuel costs alone of having such a guzzler would break me as it'd literally be 3 or 4 times less efficient than my current car, and I'd get ruined by the taxes. We get absolutely gangraped over here with fuel prices, which is why the UK and Europe are decades ahead in efficiency and refinement of egg-whisk engines. Even my 25 years old car with just carburettor for the fuel delivery should give 30-35MPG on a good day, and that's a lumpy old four banger engine.

Fuel isn't really any cheaper where I'm at, currently the low octane stuff is 114.9cents/L - which is cheap for Yellowknife, I've seen it go over \$1.30/L (High octane is at that just now, I've seen that go over \$1.50/Litre). Sometimes during the winter I'll burn \$20 of gas a day driving around town (And it's not a big town! ). So yes, I understand the struggle, you definitely made the right choice to stick with something small.

Re: Post your random pics!

Aye, and over there low octane really does mean that! Over here the watered down stuff is usually 95 no lower, with the well brewed stuff being 98 or 99!

That does seem expensive, does the US not have it rather cheap though? I was always under the impression that you could tank a car in 'merica for a small amount, like 20-30 dollars. I wouldn't have expected Canada to be so different - the prices you quote, even taking into account the terrible exchange rate, is still quite pricy.

Don't be so pretentious. It's measured differently.

Octane rating conversions - PencilGeek's BMW Blog

Also, higher octane does you zero good unless your engine has a very high compression ratio (read: sports cars)
