High Torque

High Torque with Peugeot HDi


 
High Torque

Simply put, torque is a force that tends to rotate or turn things, and is measured in Newton Metres (Nm). In a car, the engine creates torque and uses it to spin the crankshaft, which in turn rotates the driven wheels. It is the ‘pulling power’, or the force to get the car moving. One of the most important characteristics of Peugeot HDi engines are their high torque output. This is achieved with a long stroke dimension and high compression ratio. For example, in our 4 cylinder, 2.0L HDi diesel engine, the torque of 320Nm is equivalent to a typical Aussie 6 cylinder petrol engine. And with overboost, this can momentarily be boosted to 340Nm. HDi diesels really are strong work horses.

So what benefits do having high torque have? In city driving, high torque makes driving more relaxed as you have more responsive acceleration and fewer gear changes (especially when overtaking or driving up a hill). Because it is a pulling power, torque is ideally suited for towing or carrying heavy loads.

As an example, if you were to pack the car for a family holiday, you would barely notice you were carrying significant additional weight, whereas in a car with lower torque, you would notice driving becomes more of a strain, especially when going up a hill.
