Why do electric cars accelerate faster than internal combustion cars? Here is a detailed explanation

Electric cars have an instantaneous torque curve while gasoline cars have a torque curve that builds up with RPMs. You can think of this in terms of the force required to open a door versus the force required to break a plank in half.

An electric motor provides maximum torque from 0 rpm, which translates into instant acceleration and better hill climbing ability with no lag time from turbos or compressors.

Electric vehicles have a very steep torque curve because they can produce a lot of torque even at high revs. This happens because electric powertrains do not have gears and are powered by direct current instead of gas pressure, so there is no need to change gears or run the engine.

The torque curve is the relationship between the power output and the rotational speed of the engine crankshaft. The more torque (and therefore the better acceleration) is produced at low speeds where the exhaust gas flow rate is high.

Electric motors provide high levels of torque at all speeds, while internal combustion engines need time to ramp up and produce the same kind of torque as an electric car.

Combustion engines also use gears that allow them to make fewer revolutions per minute but run at higher horsepower, allowing them to travel long distances on freeways at higher speeds than electric cars that do. have no gears.

Electric cars essentially use a gear that provides maximum torque at all speeds, allowing them to accelerate faster than internal combustion engines.

The Tesla Model S Plaid is advertised to accelerate from 0 to 100 km / h in less than 2 seconds. How? ‘Or’ What? This question is easy to answer if you can see the graph of the torque curve of an ICE versus an EV, and here is an example:

  • The Tesla Model S Plaid has a 100 kWh battery and can go from 0 to 100 km / h in 1.98 seconds. The output power of the Tesla Model S Plaid is 1020 horsepower.

  • The Nissan Leaf has a 40 kWh battery and can go from 0 to 100 km / h in 7.3 seconds. The power output of the Nissan Leaf is 214 horsepower.

      Thoughts on why electric cars accelerate faster than ICE cars?

      As you can see, EVs are capable of producing a lot more torque at lower speeds than ICEs. This is why EVs are generally better for acceleration than ICEs. However, in some situations, ICE motors may be better at throttling, as the gears are used to maximize the power output.
