Torque of the Devil
Discussion
Most people hark on about their car pushing out XXX BHP, and TVR are known to up their BHP ratings a bit higher than they actually are. As a fan of the big wedges and their very Torquey engines, does anyone know if the Torque ratings of TVR engines are more reliable than their BHP ratings ?
Just interested !!!

I remember reading an article in "Motor Trend", one of the main motorhead magazines in the USA, that most manufacturers fudge their horsepower ratings at least to some extent. I would supspect that this is very true with most performance cars, including the very high end of the market.
I don't know if TVR over rates their horespower, but my Chim 450 will nail your #$#$@# to the back of the seat as well as just about any car I ever drove growing up in the USA in the late 60's and early 70's.
I guess my point is that if everyone cheats a little, then it really doesn't matter except where the rubber meets the road.

ok then, heres one for you, my cars torque is quoted as
385nm, 39.2kgm so whats that equate to in english llbs and ft?

Yep, another dumbass question, but can someone give an explanation of what torque really is/does??? the simpler the english the better please, as I am mechanically interested, but retarded.
I know that roughly speaking the bhp figure will help to determine acceleration and top speed, but what about this mysterious thing called torque?

Torque is twisting force. The torque your engine produces rotates a shaft going into your gearbox, which eventually rotates your wheels. Torque at the wheels is proportional to acceleration.
Torque multiplied by rpm is proportional to power.
If the torque is being produced at a greater rpm, the gearbox can gear down further to give more available torque at the wheels. Engine power, gear ratios, vehicle mass and drag ultimately determine acceleration. The mass is less important when it comes to top speed.

Basically, a car that has low torque and high power (motorbike engine) will go fast but will feel like hard work - through gears etc - to get it to deliver.
A car with high torque and low power (Turbo diesel)will not have the potential to go as fast, but will deliver what it does do more easily - sometimes to the extent that it feels faster in real use than a more powerful petrol engined car.
This is why modern TDs are becoming popular and are going into "luxury" cars.
