Why are electric cars able to deliver power instantly, but gas engines take more time to build up power?

An electric cars energy reserves are ready to use as they are stored in the battery. Internal combustion Engines fuel fuel source isn’t Stored as ready to use energy. It requires an explosion and Means that it’s an extra step electric cars don’t require their stored fuel a.k.a. electrical power is ready to use as power on demand in storage/your battery
Fuel based engines have a speed where they make most of their power (repetitions per min or RPM). This is the engine dial that measures the engine “rev’s.” When you put your foot on the gas, a lot of things are happening.
Parts open to let in more air, the engine’s computer injects more fuel and a big wheel in your engine spins faster and it’s connected to other wheels in the transmission, and a transmission is connected to your tires via a drive shaft.
If your engine is spinning too fast or too slow your transmission will shift up or down to a different wheel (gear) to keep your engine spinning at the speed where it makes most of it’s power. It can take some time for an engine to spin up to the RPM where it makes most of it’s power.
By comparison electric motors are much more simple. They don’t have a RPM range where they make most of their power. When electricity is switched on, an electric motor is making it’s maximum power, it doesn’t have to rev up. Electricity moves at almost the speed of light, and burning fuel to make pressure move metal parts isn’t as fast.
If you were to measure the power difference between a fuel engine and electric on a graph(x being rpm and y being torque),. A fuel engine would be a slope going up slowly and leveling off before going down a bit. An electric motor would look like a plateau, an almost straight line going up to a flat line going forward.
