Not sure if it was mentioned by vchiu

Chakib Khélil, Algerian Ministry of Energy and current chair of the OPEC mentions a $200 Barrel a possibility if the USD continues to slip.
http://www.lefigaro.fr/matieres-premieres/2008/04/28/04012-20080428ARTFIG00395-p- etrole-proche-des-dollars-.php
(in French)
OTOH, he estimates the prices may drop down to $80 (from the current $120 a barrel) if the USD value increases by 10%.
 
A few months ago, I made a guess that the barrel would reach $200. This proved too conservative, and I therefore increase it to 250$ within 30 months.
 
I estimate that within the same time frame, the US Gallon price will increase by 2,5 to 3 USD, so I would not be surprised to see 6,5 USD as a standard street price. In Europe, prices should easily shoot past the 10USD/Gal barrier at current USD/EUR rates.
 
The peak oil price is still in front of us. Let us enjoy our Caddy Escalade as much as we can now.

what i will do when gas gets to $4 a gal. i'll just think how bad its gotten for everyone else, since the rest of the world is already paying like $5 a gal. then i'll think how selfish we have become. and i'll probably look for ways around it, that will be eco friendly, cause if they are eco friendly, they will be profitable, and renewable.
 
how does paying $4 per gallon make you selfish if other countries decide to over tax their fuel to $5.
 
Nobody is stopping you from taking that extra $1 and sending it to the government.
 
If you do this you'll personally have the effect of higher gas tax and reduce your consumption; thereby alleviating your selfishness.
 
This will in turn leave more fuel on the market for us V8 drivers
 
Thanks for taking one for the team

"They have almost identical 0-60 times, and the Fit weighs only 400 pounds more than the '92 Civic. Despite that, the best they could do with the Fit was 32/37 mpg (under the old rating system), compared to 43/51 for the Civic 15 years ago (also under the old system). It's pathetic, and it's because they are not even trying any more."
 
I ran the numbers too, and this is what I get.
 
EPA lists the 92 Honda CRX manual at 36/46 or 39/49 under the new system.
 
The 08 Honda fit manual was 28/34 under the new system.
 
The curb weight for the HF was 1713 according to this site.
http://kumo.swcp.com/synth/crx/specs.html
 
Wiki says the weight of the new Fit is 2390.
http://en.wikipedia.org/wiki/Honda_Fit
 
2390 - 1713 = 677 pounds (this is a huge difference for such a small car)
 
677/1713 x 100 = 39.5% increase in weight (Fit over CRX)
 
28 x 1.395 = 39.06 (Fit estimated mpg if you reduce the weight to 1713 )
34 x 1.395 = 47.43
 
The new Fit does not appear to be that much different. (F=MA & 0.5xMxVsquared)
The Fit has tighter emission controls. I wonder what the mpg penalty is? I also wonder if the cd (air resistance) is different. The CRX tires were only 165/70 13s, that has got to be worth 20 mpg right there

Ivan, unless you are wealthy, I have a feeling that your V8 will be history if the gas prices get up to the $7...either that or you're a glutton for punishmen..I know that my 97 Town and country with a V6 will become retired.

I didn't know they were still building the CRX in 1992. The Civic went through a redesign that year, coming off more plump and rounded, and no doubt heavier. I think the car they used in that comparison with the 2008 Fit was actually the hatchback version of the new Civic, rather than a CRX. I think it was about 2100 pounds.
 
One notable difference between that '92 Civic and the Fit is that their test Civic didn't have a/c, while it comes standard on a Fit. Now, I don't know how much that really matters these days, but a/c will put a drag on the engine, even when it's not turned on. Back in the day, they used to say that buying a car with a/c was like adding the weight of an adult male passenger, but they've shrunken all those components down over the years and lightened them, so it's probably not that much of a difference these days.
 
I wonder what the overall top gear ratios are for the '92 Civic and Fit? It could just be something as simple as the Civic having a really tall overdrive gear, so while they both have aggressive enough lower gears for similar acceleration, the Civic might pull lower revs at highway speeds?

CRX vs. Fit by 1stpik
Apr 29, 2008 (4:44 am)
When people cite the "50 mpg CRX," they're referring to the CRX HF, which got 49/52 mpg. However, its engine only produced 67 horsepower -- not even comparable to the 2008 Fit's 109 horsepower.
 
The standard CRX produced 92 horsepower, and got 32/35 mpg.
 
The CRX Si produced 108 horsepower, and got 28/33 mpg.
 
So, when comparing apples to apples, the 08 Fit is equal to or better than the CRX.
 
You can see the specs for both cars here:

In addition to the tighter emission standards vehicles are also subject to higher crash standards. I seriously doubt the '92 Civic would get an acceptable crash test rating. Unless you're willing to spend a lot of money replacing steel with expensive composites improving the safety of a subcompact will almost always involve increasing its mass.
 
IMO, to make the assumption that automakers just aren't trying to improve mileage is invalid. Today's Prius and Civic hybrid don't get much better mileage than the the '92 CRX HF. These cars are designed to maximize mpg. Why would Toyota and Honda be leaving something on the design table that could improve fuel efficiency? I believe that the reality is that a functional vehicle that could transport 4 adults needs to weigh at least 2400 lbs and without some hybrid technology a car of this size won't be getting over 40 mpg, maybe with a diesel.

It's a Q45 with 340hp.
 
I routinely get 18-19mpg in regular driving. I've taken it on highway trips and have achieved 28mpg (doing the speed limit) and have had 25.x mpg for a total trip.
 
It's not great; but not terrible.
 
I recently had a PT Cruiser as a rental; not great mpg either...buzzy 4 cyl for only a couple more mpg in average driving.
 
But you may be right...at $7 a gallon it may be Jetta Blue Tech for me
