Are the figures on the right of the graph torque readings? If so can they be converted to Nm torque?.

They bottom3 lines looks like the torque curve, but the axis on the right doesnt look right, as if it has one too many numbers to be NM.

Newtons and newtons metres are like centremetres and metres.

So does mean its got 687nm of torque then.

No, those numbers represent "tractive effort". There is no way to accurately convert them to Nm.

Going by the bottom green line you have 465 nm. the top 3 lines are the power curve and the bottom 3 lines are the torque curve. Considering it had 400 stock its a pretty good effort.

No they're not. 1 metre is 100 cm.

A newton is a measurement of force required to accelerate 1 kg at 1ms^2. so thats kg.m/s^2

Whereas a newton metre value is the actual force exerted through that metre.

NM isn't simply a scaled down unit of Newton.

I probably should have payed more attention in physics then
