FAQ

Those who are looking for an answer to the question «Why electric cars don't have gears and motors?» often ask the following questions:

👉 Do electric motors have gears?

Of course, this doesn’t mean that electric cars couldn’t have gears, but they aren’t necessary. First, given MG torque / power / rpm characteristics, they’re perfect for transportation. Torque is necessary for acceleration, the most of which is generated near stall.

👉 Can electric cars have gears?

Electric cars can reach top speed in a single gear, with little compromise in low-speed driving or usability. What engineers do is pick a gear ratio that strikes a good balance between acceleration and top speed. Pick a ratio too low, and the engine will accelerate very fast but may be limited to a low top speed.

👉 Do electric cars have gears?

Electric cars are almost always automatic, meaning they don't have a clutch for changing gears, or even a gearbox. Instead, a typical electric car is a single-speed vehicle with two pedals – one for accelerating, the other for braking.

With the introduction of electric cars, the conventional gearbox is no longer present and it has its own set of benefits. The first-ever production vehicle, an 1886 Benz Patent Motorwagen, had only one gear and a clutch, but it didn’t need anything more than that. This was because the car produced just 1 HP and had a top speed of 10 MPH.

Of course, this doesn’t mean that electric cars couldn’t have gears, but they aren’t necessary. First, given MG torque / power / rpm characteristics, they’re perfect for transportation. Torque is necessary for acceleration, the most of which is generated near stall. Power is necessary for cruising, the most of which is developed at high rpm.

So instead of packing the car with numerous gears to keep the engine in its happy zone, designers of electric cars just pick a gear ratio that provides a good compromise between acceleration and...

Why do electric cars have only one gear? There are many reasons why electric cars have only one gear. The first is that electric motors rev to a significantly higher rate than internal-combustion engines. A typical electric motor can rev up to 20,000rpm, far higher than the usual 4,000-6,000rpm limit for conventional cars.

Why Don’t Electric Cars Have Transmissions? Let’s first look at the major difference between EV cars and combustion engine cars. With a combustion engine, there are gears in place, and these gears help shift the mechanics inside of your engine to hit specific speeds.

Electric cars don’t have a specific range in which they can deliver the best performance. This means they can churn out maximum torque from 0 RMP. Thus, there isn’t a need for different gear sets....

Foremost, the broad answer to the question is that electric motors don't require a number of gears due to their high-revving nature. Electric motors are also efficient across the rpm range and...

Because an electric car doesn’t need a clutch, it also doesn’t require gears. Electric vehicles don’t feature a multi-speed gearbox like conventional petrol or diesel vehicles. Instead, they have just one gear. This is because they can achieve much higher revs than a standard fuel engine. A conventional car can usually reach around 4,000-6,000 revs per minute (rpm), whereas an electric motor can achieve up to 20,000 rpm.

Do electric racing cars have gears or 81?

At its most-efficient, 93%, the MG is pushing only 100 N•m at 2,250 rpm, perfect for cruising. In any case, a multispeed electric vehicle transmission is unnecessary because even 100 N•m is plenty of torque at cruising speed. Of course, this doesn’t mean that electric cars couldn’t have gears, but they aren’t necessary.

Why electric cars don't have gears and power?

This was because the car produced just 1 HP and had a top speed of 10 MPH. However, today cars produce phenomenally high power and have jaw-dropping top speeds. This makes the dependence on a gear-type transmission even higher. However, that is not the case with electric cars.

Would gears make electric cars more efficient?

Keeping the engine in its power band also proves to be the most efficient and durable. An engine, in first gear, can easily accelerate a car to 30 mph, but would also shake itself to bits attempting to accelerate to highway speed. Likewise, that same engine would hardly be able to accelerate from a stop in 6 th gear.
