Power to Weight Ratio

[miata13B]

What do you feel the best possible Power to Weight ratio you should have on a car?

 

[SaleenASL]

the power to weight ratio should be a large number. the cars power in HP divided by its weight in lbs. you would want a high number in the numerator (HP) and a low number in the denominator (lbs). therefore, the higher the number, the better.

however, in GT3, its actually a weight to power ratio. the car's weight in kg divided by its power in HP. so you would want the smallest number possible. a light weight (numerator) and a large amount of HP (denominator).

We've discussed this before, and it was decided that in the States, what that number typically refers to is "pounds per horsepower", meaning you want a low number - but in Europe/Oceana, that number is typically considered "horsepower per kilogram" (or newtons, or whatever HP is measured in metrically), meaning that you want a high number.

EditAssuming that the PAL and NTSC versions are the same, you want low numbers, meaning each horsepower has to drag fewer kilograms. Most of the LM-style race cars seem to have a ratio number in the 1.5-to-2.5 range. A well-tuned street car will be in the 4s, and a less powerful or very heavy car may be in the 6-to-8 range.

Clear as mud? Add to that the fact that GT3 has totally screwed up the torque figures by displaying the decimal point in the wrong place (making them 1% of what they should be), and it gets confusing fast.

I dont realy know how to answer that, except I think the Zonda c12 road car has great power to wieght ratio,.

 

[Sertsa]

I just know I need to improve mine.

The lower, the better.*


*=This does not include handling. Why? Escudo's got a low ratio but it doesn't turn.

 

[SaleenASL]

exactly what i said...in GT3, the lower the better.

 

[kyle]

Well that does it for this thread.

 

[Dolbytone]

Wow, I didn't know about that torque thing... I thought the numbers looked a bit low.

 

[kyle]

Who cares about TTW ratio?

 

[Exlarus]

all i can tell you is escudo has the lowest obviously =]

the torque to weight ration is only remotely valuable in the bottom end. off idle power delivery, turning on the accelerator, and, in the case of a rally, sow drifting, are the only times one really needs to worry about torque-to-weight.
