Thanks to that instant torque, electric cars are very quick off the mark – like the Tesla Model 3 pictured above. Internal combustion engines only produce maximum torque at certain engine revs. But what marks electric cars out is that all the torque is available instantly. How much torque an electric car produces depends on how powerful the motor is and the numbers for some don’t look that impressive. What about electric cars? Do they have lots of torque? They will be much more fuel-efficient than a petrol car. That’s why diesel cars are a good choice if you take long, high-speed motorway journeys. Low torque engines are less economical because they have to work harder than high torque engines. Beyond 500 Nm (369 lb/ft), most engines come with an automatic gearbox anyway since they’re better able to cope with an engine that strong. It’s worth noting that engines producing much more than 400 Nm (295 lb/ft) of torque, whether petrol or diesel, are usually at their best teamed with an automatic gearbox. If you need a car to tow a trailer or caravan, you’ll need the extra strength of a high torque engine to help pull the extra weight. A turbocharger helps produce more pressure inside the cylinder, which again increases torque. See the pulling power of torque in our tug of war video.Īlso diesel engines tend to be turbocharged. To put it simply, the more torque you have, the more effortless the acceleration will feel. A car with high torque – a long spanner – will. A car with low torque – a short spanner – won’t accelerate quickly at that point. You’re driving along at 40mph in top gear and put your foot down. Using a longer spanner takes less effort to tighten the nut to the same extent. Using a short spanner takes a lot of effort to tighten the nut. Imagine you’re tightening a nut with a spanner. Torque tells you how strong an engine is. But most people don’t drive like that, which is where torque comes in. An engine with lots of power will rip round to the rev limit, making lots of noise and feeling very exciting. Power tells you how fast a car will go with a certain engine. In this advice guide, you’ll find out everything you need to know about torque. Torque matters at least as much and possibly more, depending on how you use your car. Power is self-explanatory but torque? Not so much.īig power numbers might look impressive, but they’re only part of the story when figuring out what a car will be like to drive. Ensure spring balances are calibrated to read 0N when no mass is attached before use.When you look at the specification of a car’s engine, you’ll see numbers for power and torque. Choosing a model which does not allow the spring to be overstretched will increase its lifespan as well as to provide a more accurate reading over time. The more robust models are often found to be the cylindrical forms however, many models are prone to overextension of the spring mechanism if excessive weight is added. There are many types of spring balances available. As objects are added, the spring stretches and the resultant force can be read from the scale. The other end is attached to a hook on which you can hang objects. One end (the top) is usually fixed to an adjuster which can be used to calibrate the device. Spring balances consist of a cylindrical tube with a spring inside. ![]() The weight of an object is a measurement of its mass x gravity (W=mg). This force is usually measured in Newtons and is essentially the weight of an object. They are commonly used to measure the force exerted on an object. A spring balance (or newton meter) is a type of weighing scale. ![]()
