How can I tow a 6500 lbs trailer with a Fiesta?



You can't. But the equivalent motor in a 2500lb small truck (like my '80 Toyota) will pull it. Yeah, you'd do 45mph up the hills. Go up to the 1.6L ecoboost and it should maintain highway speeds. And get great mileage when not towing.

My Toyota has maybe 75hp left. It's hauled some crazy loads over big hills. 10,000lbs combined load (truck+trailer) from coast to coast and averaged 20mpg for the trip.

It's gotten 8,500lbs (car hauler with a full size truck on it) over a mile of 11%, but it was mighty hot at the end. 4800rpm (power peak) in first the whole way. If I'd had to stop for any reason, I would have had to back all the way down and start over, no way could I have pulled out on that hill.

A 200hp turbo 4 would do just fine. Especially if you aren't hauling an extra 2000lbs of truck you don't need.

Uh, yeah it is AN answer. Keep trying, eventually you'll post something that doesn't make you look dumb.

Leave it up to Paul to argue semantics of math!

For every vehicle that gets 20mpg you need 3 other cars that get 100 mpg in order to average out at 50 mpg.



That would average out at 80 mpg.


The three other cars would need to get 60 mpg.






Math is not really Paul's strong suit.

You tell me Yuki: 4 cars travel a total of 400 miles and consume a total of 8 gallons of gas. What is the average mpg for the 4 cars?

@Groucho: Cars with better and worse gas mileage do not consume exactly the same amounts of gas. If they did, we wouldn't care about gas mileage.

It actually looks more like a thinking problem than a math problem.

So you couldn't calculate it?

I thought you were Asian.

Like I said, it's not a problem of calculation. You're looking at something besides average MPG.


If you have two cars with an average MPG of 50 between them that doesn't mean they'll always use the same amount of gas no matter what the distribution is. I.e. two cars that each get 50 MPG use a lot less gas than one car that gets 10 MPG and one car that gets 90 MPG.


You're trying to use a distributional argument to argue an average isn't an average. Which is stupid. It's still an average.

The car manufacturers care about whichever method the government uses to calculate average mpg, not whatever one is more mathematically "correct".
