A Forgotten Invention From Decades Ago Returns and Promises to Change Design, Interior Space, and Efficiency of Electric Cars, Reopening an Old Debate in the Industry
Have you ever imagined a car without a hood, without a front trunk, and without that enormous space reserved only for the engine?
It sounds futuristic, but this idea is much older than it seems.
The technology of motors installed directly in the wheels, known as Wheel Motors (WMs), emerged in 1900 from the hands of Ferdinand Porsche.

Motorola launched the Signature with a gold seal from DxOMark, tying with the iPhone 17 Pro in camera performance, Snapdragon 8 Gen 5 that surpassed 3 million in benchmarks, and a zoom that impresses even at night.

Satellites reveal beneath the Sahara a giant river buried for thousands of kilometers: study shows that the largest hot desert on the planet was once traversed by a river system comparable to the largest on Earth.

Scientists have captured something never seen in space: newly born stars are creating gigantic rings of light a thousand times larger than the distance between the Earth and the Sun, and this changes everything we knew about stellar birth.

Geologists find traces of a continent that disappeared 155 million years ago after separating from Australia and reveal that it did not sink, but broke into fragments scattered across Southeast Asia.
The concept was shelved for decades but now reemerges as a strong solution for the new phase of electric mobility.
The Return of an Advanced Invention Ahead of Its Time
For practically the entire 20th century, the position of the engine defined the performance of cars, the interior space, and even the design of the vehicles.
This pattern dominated the industry for over a hundred years.
But that is changing.
By placing the motor inside each wheel, the transmission shafts, differentials, and various complex mechanical systems disappear.
This paves the way for simpler, lighter, and far more efficient cars.
In the past, this type of motor did not thrive. The technology was still limited, and the world did not have the electrical infrastructure to support this concept.
Today, the scenario is completely different.
The advancement of batteries, automotive electronics, and the global focus on sustainability puts wheel motors back at the center of discussion.
Companies like Elaphe Propulsion Technologies from Slovenia already have prototypes ready for use in production models.
More Interior Space, More Efficiency, and Better Performance
The advantages of this architecture are many.
When the motor no longer occupies the front and rear space of the car, there is more room for larger batteries, new internal layouts, and more comfort for those inside the vehicle.
Each wheel receives its own motor and begins to act independently.
This allows for much more precise torque control in curves, inclines, and uneven surfaces.
The result is superior stability and handling that surpasses traditional systems.
One of the most advanced models is the Sonic 1, developed by Elaphe.
Compact, lightweight, and designed for wheels up to 21 inches, it works with high-performance brakes and eliminates energy losses typical of axles and differentials.
In practice, it delivers instant torque and enhanced energy efficiency.
Another important point is the economical aspect.
With fewer mechanical components, production becomes cheaper, and maintenance costs decrease.
A New Path for the Global Automotive Industry
Wheel motors not only change performance.
They can completely alter the way cars are designed.
Modular platforms become simpler and easier to adapt.
This opens up space for compact versions, family sedans, and even large electric SUVs, all using the same base.
This standardization could accelerate mass production and strengthen automakers that adopt the technology first.
The resurgence of wheel motors shows how visionary ideas can return with force when the technological context changes.
What once seemed a bold experiment in the early 20th century can now turn the key to a new generation of more efficient, cleaner electric vehicles with a completely different design from what we know today.
