I'll prove you all wrong when I'm the first person in history to haul a horse trailer from sea to sea using a Toyota Corolla. If my calculations are correct, it should be about as difficult as driving an 18 wheeler. The tare weight of an 18 wheeler is about 20,000 pounds and the department of transportation says the maximum interstate load is 80,000 pounds total which would be 60,000 pounds towed. That puts it at a weight ratio of about 3:1. A Corolla carrying me and a bunch of other shit is about 3000 pounds, so multiply 3 = I'll haul 9000 pounds of horse + trailer. An 18 wheeler has about 700 horsepower, so that would be 60,000/700 = 85.7 pounds per horsepower maximum. My Corolla has 130hp, so the maximum would be around 130*85.7 = 11,141 pounds maximum. I said I would only pull 9000, so this is all good.


Alrighty let's git er dun. I need you guys to pray that my transmission doesn't melt. If I get stranded in the middle of nowhere, those horses might starve to death :(

Congratulations - this is you.

Oh, just FYI...the 700hp Volvo semi engine makes over 2300lb-ft of torque, and it's not hooked up to a four speed transmission.

Don't worry about the transmission. I'll just sloooooowly accelerate until first gear is rolling fast enough to lock the torque converter. After it has been directly coupled, I can floor it all I want.

Video is blocked at work. Can you describe what it shows?

It shows what'll happen to you. Watch it later.

Slowly accelerate in first gear? Yeahhhh, haven't you heard semis leaving a traffic light? They're in, like, fifth gear by the time the trailer clears the intersection..you'll be lucky if you move faster than the tricycle on the sidewalk. Given any sort of hill, your torque converter is going to be crying.

Fine then I'll put a big cooler on the torque converter. Don't worry about hills since those shouldn't be a problem once everything is up to speed. As long as the vehicle is already moving, I can make it up the hill in first gear at max power. First gear in my Corolla ends at a little under 60km/h which would be about 16.6m/s. The engine is rated for 132HP at the crank but let's say 100HP after drivetrain loss. Converted to metric would be 100 * 746 = 74600W. P = vF so F = P/v = 74600/16.6 = 4494 newtons. Converted to pounds would be 1010 pounds of force. I said my car would be 3000 pounds and the uhaul of rocks is 9000 so that's 12000 pounds total. Gravity I'm fighting against would be shown as 1010 = 12000*sine(theta). Theta is then equal to 4.83 degrees maximum slope.


Ok you were right. I can't pull a uhaul full of rocks up a hill. It can't even do 5 degrees.

edit. Since I was just looking at first gear I probably should have used maximum torque at 4000 rpm instead of maximum power at 6000, but it wouldn't make a difference really.

Yeah a fully loaded semi starting from a stop will have shifted through many gears before a car shifts out of first.

Your trans will melt before you reach the town line, aux cooler or no.

Why again are you determined to destroy your car?

I don't like the term destroy. I like to think of it as using the vehicle to its full potential. If you buy a car that has 500HP and you never floor it or run it at max power, then you just wasted money on all this power you'll never use. With a Corolla, it really feels like you got your money's worth. The thing has 132HP and you'll use every bit of it. The thing redlines at ~6400, and the engine will hit that limit every single day when getting onto a high speed road. The first gear is there to give it extra torque, and you'll use every bit of that torque when flooring it in first gear and running up to redline.

Things break when you use them. Breaking it means you were using it. If you get a new car and the transmission still works in your old car, then obviously you weren't using that transmission to its full potential.

the shame here is
the tacoma is a bloated crapbag and built like junk+its overpriced
the stranger has been idle a decade+
the canyonrado is a joke from anyone ive asked
ive aint seen rcab nissan frontier,do they even exist?
the dakota.might as well buy fullsize.
i want a 6+ft bed,4cyl,5spd,split seat 4x4 that gets ~25mpg..is it the impossible dream?


I miss the fuel econ of my ol s10 with the 2.2, it was a dog but it sipped gas and i could still tote around my yaks and jonboats with it+do light dity truck stuff @~25mpg
or my old ranger for same reason
my sierra is a gas pig,i love the truck but i avg ~13.4 mpg around town

Why the hate for Colorado/Canyon? I had a rental Colorado and it was an awesome truck, aside from the lack of ground clearance. It had a nice ride and the frame felt really stiff and sturdy.

I had a rental when my Tacoma was in the body shop and I couldn't wait to get my truck back..the Colorado had shit for ground clearance and it felt like a car.

my taco was the bloated newer body style
they aint the rep of the narrow bodies
aint built the same either
mine was a pavement queen
and i wont belabor the issues i ad with it
(which are well doc'd, and there are well docd issues with the newer ones in general)
i *still* get mocked from my mechanic friends about the plastic clutch pedal in the tacoma

No matter how you figure it just let a DOT cop see you trying to pull 9K lbs total with a little Corolla and those rocks will be starving on the side of the road... The car is only rated as per DOT to tow 1508lbs... As for those that try to pull with a 1/2 ton or less truck (2wd) more than 8K lbs and 9K lbs or so with a 4wd then your asking for trouble... Even with trailer brakes your maxing out your trucks brakes which will both wear them out really quick or damage them to the point of complete failure... Thats if your transmission survives and your pocket book as well because the milage will go to shit no doubt... There is a reason why they make 3/4ton and 1 ton trucks and its not just to look like billy bad @zz... Also for light towing a gas engine is fine but nothing beats a Diesel for raw power and torque which also translates into more MPG... I pull a 10K+ lb travel trailer that is 12' tall and 33' long and still get 10-12mpg depending on terrain and wind conditions... Sorry but your theory of a gas engine doing this without some intense modds and such just wont cut it... Also the brakes on my truck have more surface area on 1 wheel than all 4 combined on your Corolla... This is a simple apples to oranges matter and they dont interchange...
