Why are electric cars so fast?

Electrified vehicles used to have a reputation for being slow and boring.Just ask the first-generation Toyota Prius.But today's EVs are the least like the original Prius you can imagine.The fastest vehicles on the road today are high-performance electric cars, and that trend isn't going to stop anytime soon.

An electric car like the Tesla Model S Plaid can absolutely destroy everything on its road in terms of performance.This trend extends across segments as well, as even electric pickups are faster than most sports cars.So the question is: why are electric cars so fast?


Instantaneous torque

Torque is the rotational force that enables your vehicle to move.In a gasoline engine, torque is produced by the combustion pressure of the gasoline/oxygen mixture on the piston heads, which creates a rotational force that turns the crankshaft.To achieve this rotational force, many moving parts must be added to this equation.If you've ever seen a model of the inner workings of an internal combustion engine, you'll immediately notice how many parts have to move to make the driveshaft spin.

Gasoline engines are also usually connected to a transmission and differential, further slowing the process of moving a gasoline-powered car forward.

The great thing about electric vehicles is that the electric motor produces 100% torque instantly, without any hesitation.Not only that, but there aren't many moving parts that get in the way of forward momentum.Many EVs are linked to a single-speed gearbox, so your forward isn't hindered by shifting.

No matter how fast the fastest transmission shifts, it won't be faster than one that doesn't need to shift.Some EVs even have four separate electric motors, one for each wheel.This system is one of the most advanced drives on the road today, and is also available in the technologically advanced Rivian R1T.

When you have an electric motor driving each wheel, you can remove the locking differential, meaning off-road potential will be better than a vehicle that relies on a lock.If you have an electric motor for each wheel, you can also get no differentials at all, as well as a heavy driveshaft connecting the rear wheels to the transmission and engine.The concrete result of this instant torque is that you feel the power as soon as you touch the accelerator pedal, and you end up stuck in the seat.

Amazing traction equals great performance

High-performance electric vehicles are taking over the automotive world.Their numbers are absolutely ridiculous, and even the most expensive diesel locomotives struggle to keep up with the fastest electric cars.

In fact, even EVs that aren't supposed to be sports-car rivals end up embarrassing high-performance diesel cars from time to time.The fact that the electric motor can produce its torque instantly, and produce such high revs, means these vehicles are destined to be performance juggernauts.Not only that, but electric vehicles are also masters of getting off the assembly line quickly.

This is mainly due to its enormous traction, the implementation of dual-motor all-wheel drive, and its enormous mass.The combination of all-wheel drive, instant torque and a low center of gravity is a recipe for insane.Why?Because due to the combination of all these favorable factors, the car can unleash a lot of power.

More motors, faster acceleration

This is even more pronounced when a vehicle has three electric motors (Tesla Plaid) or four electric motors (Rivian).The prime example of this is the Tesla Model X Plaid, a family SUV that will wipe out any supercar that gets in its way.

The Model X Plaid will do 2.5-0 mph in 60 seconds (basically faster than any supercar) and will do the quarter-mile run in 9.9 seconds.Those numbers are absolutely outrageous and make the Model X Plaid one of the fastest vehicles on the road.Interestingly, while the Model X Plaid beats exotic cars with a $50-plus price tag, at its core, it's a simple people-carrying vehicle that allows you to go grocery shopping in great comfort.According to Lamborghini, the Lamborghini Aventador takes about 0 seconds to go from 62 to 2.9 mph.

This means very simply, if you happen to own a Lamborghini, if you value your self-esteem, stay away from any rally involving Tesla.

The Model S Plaid is in a whole other universe and is actually the fastest-accelerating production car, so no need to say anything here.However, shocking numbers are absolutely commonplace for this innocuous-looking electric vehicle. The Model S Plaid even wiped the numbers from its sibling, the Model X, with a 0-60 mph time of 1.99 seconds (with scrolling) and a quarter-mile time of 9.23 seconds, which is pretty amazing.

The Model S Plaid isn't just faster than a supercar; it's also faster than many race cars.Next, pickups like the Rivian R1T also have insane acceleration figures that rival the best combustion-engine supercars, while being infinitely practical.When properly equipped, the R1T can go from 3 to 0 mph in about 60 seconds.

This is also thanks to the instant torque of the electric motors, and the fact that this truck has four electric motors (one for each wheel), ensuring the truck has the best possible traction at all times. Rivian is a pioneer in this area, but adding electric motors to every wheel is a trend that's likely to continue.When adding electric motors to control each wheel, the possibilities are endless, from torque vectoring to insane off-road potential. Rivian itself has proven this with the "Tank Steering" feature on the Rivian R1t.

The dominance of EV performance won't stop

The current performance of electric vehicles is just the tip of the iceberg.Electric vehicles have a lot more to offer once the technology that powers them evolves.It's scary to think about how fast these vehicles will get once battery technology continues to improve.
