FAQ

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

👉 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.

👉 Will electric cars have gears?

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.

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.

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 ...

Manufacturers like Renault have put manual gears into cars like its Formula One car and Genovation GXE. You'll never have to worry about stalling again in an electric car! If that's not a reason to not have manual gears fitted, we don't know what is. Why ruin a good thing if you don't need to?

Transmissions have Several Gears. To better understand why an electric car does not have a need for a transmission, it is helpful first to review the function behind one in the first place. Transmissions are meant to help take the power that is generated from the engine and transfer it to the driveshaft.

This also means electric cars make maximum torque almost instantly from zero revs, so they don't have a specific rev range suited to low-speed driving or acceleration. The reason conventional diesel and petrol cars need a gearbox with multiple gears is because these engines are only capable of generating useable torque and power within a narrow band of engine speed.

Why don’t electric cars have neutral? Electric cars lack a transmission which would house multiple gears, including neutral. Transmissions are not necessary for the functioning of electric vehicles because power to the wheels can be regulated through the amount of current flowing through the batteries.

Why do electric cars have such a low top speed for their horsepower? There are two basic reasons: First - even if electric motors have maximum torque at zero rpm, it is still limited. And those motors still have some maximum rpm. Designing them fo...

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 motors?

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.

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.
