Hmm, I don't care that much how a car delivers its power... It just has to be fast... So, I'm not voting :twisted:

A good snippet:
Torque, is commonly misconstrued as power at low rpm. Please let go of this misconception! It is not. To move a car faster, at low (as well as high) rpm, the engine must produce more horsepower. If a 3000-pound car should do the quarter in 10 seconds , we have to have 600 horsepower at the rear wheels. It is mathematically impossible to tell how many foot-pounds of torque that is needed to do the work. Of course, we can say, xxx fp of torque at yyy rpm , but then we are talking horsepower again. ( hp = torque x rpm ) , hence, high rpm torque produces the best HP. In other words, I like my motor to produce torque at high rpm. In fact, the best torque producers are very high rpm motors. Those take real advantage of tuned intake and exhaust system, ported heads etc. So, when it comes to specify a quantity of work, the correct way of referring to it is horsepower. Even at low rpm.......

If you had to choose between two cars (irregardless of brand or make) what would you get? One with more torque or horsepower? Why?

Dammit you got in before I could say it...

Torque and Horsepower are a function of eachother...
 
I think there is much fun to be had being able to smoke the rears at 80+km/h in 2nd just by mashing the accelerator, it's all torque baby!!

My words exactly ;)
You dont need lots of HP to have fun...look at the WRX, doesnt have much
HP but has shitloads of torque and makes for a great drive :driving:
 
It depends alot on application I guess. I like the ability to be able to cruise around (at lowish revs) in my 5.7litre, carrying 5 people with minimal loss of performance.

I don't need to rev the crap out of it (to obtain high HP) to get it to start to boogie, but lucky for the me the LS1 likes a good rev and it gets up and boogies even quicker!
 
I'd like to have al ot of both... A large and powerful engine developing lots of torque, that would be so great. But because I have to choose, I'll go for torque. It's more useful in everyday driving than lots of horses. :)
 
well... both has their pros and cons and they depend on the situation, if I am a regular highway cruiser, I would prefer a high-torque and high CC car so on the highway, I can cruise and overtake while keeping it at low revs rather than have the engine screaming just to overtake a car
 
As long as the car is fun to drive it doesn't matter. :)
 
power = torque * engine rpm / 5252 (power in HP and torque in fout pounds).

It's not a question of horsepower OR torque. It's a question of HOW MUCH power is generated, and WHEN/HOW this power is generated. In the end it's the horsepower that makes you go fast and it inevitably requires torque to produce horsepower.

Thanx, finally somebody said it.
You can see torque as the force that makes you accelerate and hp gives you the ability to have a high top-speed(do to the equation). If you like a car that accelerates fast, you want lots of torque, but with a good range. If you want a car that accelerates fast and has a high top speed, you need a turbo (actually, it's more difficult than this).

^or revs

you don't need a lot a torque, just make the engine rev till 10K rpm, it'll have as much hp

(2 stroke all the way :p )
 
I voted HP, because every time people get started about lots of torque they will eventually get around to DIESEL engines... :thumbsdown: So they have some power, but only from like 2,250 to 3,500 rpms maybe. *yawn*
 
too much torque = too much spinning
 
Torque is awesome - just look at the Ginetta G4 on GT4 - tons of torque, yet only about 100hp - British engineering at it's finest :D

Power-Weight Ratio is the be all and end all for me :)

Mate... thats dead wrong.

As I said in a post before. HP is a function of torque. You have to understand that torque curves start to drop off when getting to higher engine speeds. Therefore you need a fatter/more square torque curve for high top speeds, instead of having the curve tail off towards the top rev range.

I know what you're saying, but I'm still right. It's a bit more complicated, but this is how it is. If you have tons of torque, but little horsepower, it means that a high rpm there's little power, so less high speed.

Greetz Johan
 
^^^ WTF

Listen to what your saying mate... If you have tons of torque... look at the dam equation!!!

Its TORQUE TIMES RPM meaning more torque means more horsepower. Its not that complicated at all. We learnt about this in 1st year engineering.

Torque is a force times a moment arm right. Kilowatts (or horsepower) is energy per second. Kilowatts are a MULTIPLICATION function of torque. The only way your gonna have lower power at higher rpm is because of, as I said before, the characteristic drop off in torque in IC engines at higher rpms.

You are not right. Sorry.
