<\/figure>What is Torque?<\/strong><\/h2>\n\n\n\nTorque is a rotational force; it’s what makes things twist or turn.<\/p>\n\n\n\n
In a car, it’s the twisting force the engine produces to turn the wheels.<\/p>\n\n\n\n
A simple way to think about it: when using a spanner on a bolt, the harder you push, the more torque you’re applying. Your engine works on the same principle.<\/p>\n\n\n\n
It’s also worth knowing that torque and power (measured in horsepower or kilowatts) aren’t the same thing. <\/p>\n\n\n\n
Power is how quickly work is done; torque is the force that makes it possible.<\/p>\n<\/div><\/div>\n\n\n\n
In a nutshell:<\/strong> Torque = rotational force. More torque means the engine can push harder against the resistance when you are pulling a caravan or climbing a hill.<\/p>\n\n\n\n<\/p>\n\n\n\n
How to Calculate Torque in Cars<\/strong><\/p>\n\n\n\n<\/p>\n\n\n\n
The formula for torque is straightforward:<\/p>\n\n\n\n
<\/p>\n\n\n\n
Torque (Nm) = Force (N) \u00d7 Distance (m)<\/strong><\/p>\n\n\n\n<\/p>\n\n\n\n
Force is measured in Newtons (N) and distance in metres (m), giving a result in Newton-metres (Nm). So a mechanic applying 50 N of force to a 0.3 m spanner produces 15 Nm of torque.<\/p>\n\n\n\n
<\/p>\n\n\n\n
In an engine, the crankshaft is like a turning rod. The pistons push against it from a set distance from its middle. The further the pistons travel and the harder they push, the more turning force the engine produces.<\/p>\n\n\n\n
<\/p>\n\n\n\n
How is Torque Measured?<\/strong><\/p>\n\n\n\n<\/p>\n\n\n\n
Knowing how to measure torque in cars is just as important as understanding what it is. In the automotive world, torque is most commonly measured in Newton-metres (Nm) in the UK and Europe, or in pound-feet (lb-ft) in the United States.<\/p>\n\n\n\n
<\/p>\n\n\n\n
The conversion is simple: 1 lb-ft = 1.356 Nm.<\/p>\n\n\n\n
<\/p>\n\n\n\n
The main tool for measuring torque is a dynamometer, or “dyno.” The car’s driven wheels sit on rollers, and as the engine runs at different speeds. <\/p>\n\n\n\n
<\/p>\n\n\n\n
The dyno measures the force needed to keep those rollers turning, calculating both torque and power as it goes.<\/p>\n\n\n\n
<\/p>\n\n\n\n
The results appear as a graph showing engine speed (RPM) against torque and power. <\/p>\n\n\n\n
<\/p>\n\n\n\n
This tells you not just the peak figures, but exactly where in the rev range they’re reached, giving you a good sense of how the car will feel on the road.

<\/figure>\nWhy is Torque in Cars Important?<\/strong><\/p>\n\n\n\nTorque matters more for everyday driving than headline power figures. Here’s why:<\/p>\n\n\n\n
\n- Pulling away and accelerating:<\/strong> Strong low-down torque means the car feels effortless from a standstill, without needing to be revved hard.<\/li>\n\n\n\n
- Towing and heavy loads:<\/strong> High torque lets an engine sustain pulling force over long distances without straining.<\/li>\n\n\n\n
- Overtaking: <\/strong>Mid-range torque determines how quickly the car responds when you need to accelerate from 50\u201370 mph.<\/li>\n\n\n\n
- Off-road: <\/strong>Low-RPM torque lets 4x4s crawl over obstacles without thrashing the engine.<\/li>\n<\/ul>\n\n\n\n
<\/p>\n\n\n\n
It’s also why diesels have long been popular for UK company cars, their strong low-down torque makes them feel effortless for motorway driving and towing.

What is a Torque Converter?<\/strong><\/h2>\n\n\n\n<\/p>\n\n\n\n
If your car has an automatic gearbox, it almost certainly uses a torque converter, a fluid coupling device that replaces the clutch found in a manual car.<\/p>\n\n\n\n
<\/p>\n\n\n\n
It works by using hydraulic fluid to transfer power from the engine to the gearbox via three components: a pump (engine side), a turbine (gearbox side), and a stator in between. When the engine spins, fluid is pushed against the turbine, which drives the gearbox.<\/p>\n\n\n\n
<\/p>\n\n\n\n
What makes it clever is that it can multiply torque at low speeds. When pulling away, the stator redirects fluid to amplify the torque being transmitted, giving automatics their characteristically smooth, strong pull-away feel.<\/p>\n\n\n\n
<\/p>\n\n\n\n
Most modern torque converters also include a lock-up clutch that mechanically connects the pump and turbine at higher speeds, improving efficiency and reducing heat.<\/p>\n\n\n\n
Examples of Torque Car Ranges<\/strong><\/h2>\n\n\n\n<\/p>\n\n\n\n
Torque ranges vary widely across vehicle types. Here’s a general guide to give you an idea of typical figures:<\/p>\n\n\n\n
