Auto Industry FINALY Supporting Fuel Economy Amendment

This really isn't as good as it sounds. Automakers are pushing a bunch of propaganda on talk radio urging voters to call in and ask for this alternative bill to be passed. They have these radio actors talking about how cars will become less safe by becoming more fuel efficient (because of less weight), and that you won't be able to tow your boat if the CAFE standards increase. Ugh!

Note: some of the information below is from a previous version of the bill (from 2002). I'm not sure what all changed, but I do know that the current bill has the same authors (one of whom represents Detroit) and still empasizes the use of alternative fuels like ethanol, which allows companies to focus less on the actual efficiency of their vehicles and more on the type of fuel used.

 

I don't know whose math you're using, but the average gas mileage of five 15 mpg SUVs and a 150 mpg supermiler each driven the same distance is 17.6 mpg ( the six vehicles would require 5.1 gallons to drive 15 miles each for a total of 90 miles) The average of one 15 mpg SUV and one 150 mpg supermiler is 27.27 mpg.

It's pretty clear that if many people are going to continue driving SUVs, a modest improvement in performance of those is better than the addition of a very small number of super-efficient vehicles.

I really hope they don't put any sort of plug in cars into those averages. Simply because seriously how can you say a car has "150 MPG" if it's a plug in? If you drive it very short distances, and don't need to use any sort of gas then it has an infinite MPG, if you drive long distances distances in one shot you'll have a much smaller MPG rating. At least with a hybrid (non-plug in) there is no deception involved, sure you can get "99.9 MPG" if you're going 30 all on electric, but eventually the electricity goes away and the gas engine takes over and your back to a real average.

Unless they find a way to figure out how much pollution X # of kWh of juice is to charge your batteries then they should stay out of any CAFE standards.

5*15 = 75

75+150 = 225

225/6 = 37.5 MPG

Sorry, but you can't average mpg by adding them up this way. This is a common error frequently made by the mathematically challenged. Math examiners trip students up by getting them to calculate average speeds - for example, if you drive 60 miles at 60 mph and another 60 miles at 20 mph, what is your average speed? Your (incorrect) approach would say (60+20)/2 = 40 mph. In fact, it takes 1 hour to drive the first leg and 3 hours to drive the second leg, so the average speed is 120 miles/4 hours = 30 mph.

In the same way, you calculate the average mileage of a fleet by taking the total miles and dividing by the total fuel.

Check here for how the government does it:

Wanted to add...

For those that have a boat or trailer to pull, the 2006/2007 Highlander SUV can tow up to 3500 pounds, and the one coming out in the fall (2008 model) has a towing capacity of 5000. Most folks dont use or need more than that.
We have a 2006 Highlander and are getting 26ish MPG. (more on longer trips). So no need to buy a gas guzzling SUV, this truck is a great option.

I get tired of hearing the US auto industry whinning about not being able to get milage high enough to meet new CAFE standards, and that it isn't feasable. When 3 SUV's on the market already do!!!! and two of them are american (ford escape/saturn)!!

 

So this is the best that Congress can do, while peak oil is looming along with dependence on imported oil from a hostile (to the USA) and unstable region? Americans certainly deserve better from our Government.

Why do we have to wait until after 2020 for SUV's with >30mpg. The Honda CRV already gets 30mpg - today. Instead of spending a few extra thousand dollars for the leather interior, how about substituting a weak hybrid powertrain along with replace a few steel components/panels with aluminum and you're now at 35mpg (for about the same additional price as a leather interior, dual climate, wood trim, etc). Car manufacturers can meet the proposed post 2020 mpg standards today -even for SUV's. Creating a post 2020 mpg standard is nothing more than a political feel good stunt that the politicians can use to pretend that they are doing something without actually doing anything of substance that might offend a corporate contributer or a couple of voters.
