Advice please

Which "max torque" is better? 149nm @ 1700 RPM or 142nm @4000 RPM?

149NM at 1700 RPM.

It depends on the type of car and what you want to do with it 149nm @ 1700 RPM is better for a daily drive.

first one is a diesel and second one is a petrol is my guess.

Two very different driving experiences.

And also what it weighs.

The second one might actually be better than the first when it comes to actual driving.

Well, yes and no, 1st will be better in traffic.

Also depends on the torque curve.

 

[SauRoNZA]

Well, yes and no, 1st will be better in traffic.

Not if it's inside a 4-ton truck and the second engine is inside a 1.5-ton Polo.

Not necessarily..

You have no info on the actual vehicle itself....

That value is just one point on a torque vs rpm graph. You need to see the whole graph to beable to make any sense of it.

A turbo diesel would make torque low down and then nothing higher up the rpm range.

An older turbo petrol, low torque at low rpm and high torque at medium to high rpm. The opposite of a turbo diesel.

A modern turbo petrol, a high flat torque curve from low to medium high rpm.

Older n/a engines a more peaky torque peaking lower down or higher up depending if the motor was designed for lazy driving low down torque or high rpm racer.

Later advancements like variable valve timing, variable lift, variable intake manifold length etc smoothed out the torque curves so that modern motors have a more even torque spread and less of an "on cam" / "off cam" feel.

Less torque, more action.
