Electric vehicles have transformed the driving experience, offering instant acceleration, smooth power delivery, and remarkably quiet cabins. While those qualities appeal to many drivers, dyed-in-the-wool driving enthusiasts still miss the mechanical sensations associated with traditional combustion engines.
Automakers have already started experimenting with ways to make electric performance cars feel more engaging. Artificial engine sounds, simulated gear changes, and adjustable driving characteristics are becoming increasingly common in enthusiast-focused EVs.
Audi appears to be exploring some ideas that are a bit, well, stranger is probably the best word to describe them. A recently published German patent application outlines a collection of technologies designed to introduce additional sights, sounds, vibrations and even smells into the electric driving experience.
Some of the concepts are relatively straightforward, while others sound like something from a science-fiction movie. Among the more unusual proposals are electric cars capable of producing visible sparks, generating artificial turbo lag and releasing different scents depending on how they’re being driven.
Audi Wants Electric Cars To Feel More Mechanical
German patent application DE 10 2025 107 436 A1 describes several methods of making electric vehicles feel less isolated from their powertrains. One proposal involves creating a physical connection between the electric motor and passenger compartment to transmit mechanical vibrations directly into the cabin.
Audi suggests using specialized vibration-transmitting components, potentially incorporating hollow steel structures, to deliver sensations that would normally be suppressed. Reducing certain sound-insulation materials could also make the electric motor’s mechanical noises more noticeable.
Another interesting concept would allow the electric motor to spin independently of the wheels. By temporarily disconnecting the motor from the drivetrain, drivers could effectively rev their EV while stationary, mimicking the behavior of a combustion-powered car in neutral.
Artificial Turbo Lag Could Make Acceleration More Dramatic
One of the defining characteristics of electric motors is their ability to deliver torque almost instantly. Audi’s patent suggests deliberately modifying that response to recreate the delayed acceleration associated with turbocharged combustion engines.
The system could introduce simulated turbo lag, followed by a stronger surge of acceleration. It might seem counterintuitive to intentionally delay an electric motor’s response, but the goal would be to create a distinctive performance sensation.
The application also discusses temporarily increasing available power or torque, either through driver inputs or software anticipating a request for additional performance. Such features could allow future Audi EVs to deliver different driving experiences without changing their underlying hardware.
Sparks, Electric Arcs, And Even Artificial Smells
Perhaps the most unusual proposal involves creating visible sparks outside the vehicle. Audi describes a system that could drag a replaceable metal component against the road surface, producing sparks during acceleration, braking, or other driving situations.
Another concept involves generating electrical arcs, potentially placing them outside the vehicle or somewhere visible to the driver. These effects could respond to accelerator inputs, adding an entirely theatrical element to the driving experience.
Audi has also considered introducing different scents into the cabin depending on the selected driving mode. Relaxing fragrances could accompany comfortable cruising, while more stimulating scents might appear during enthusiastic driving.
The patent even references an electrical smell reminiscent of a model railway, potentially recreating an unusual sensory association with electric machinery.
Audi Has Some Other Wild Ideas
The proposed technology extends beyond mechanical sensations and artificial fragrances. Audi also describes projecting visual effects onto the windshield, potentially creating a dramatic impression of speed or displaying calming scenery.
Other concepts include electronically adjustable exterior paint and animated graphics that respond to driving conditions. The patent even suggests changing the appearance of exterior body panels, such as turning the fenders red during sporty driving.
Of course, a patent application doesn’t mean Audi intends to introduce every one of these technologies into production vehicles. Some concepts could remain experimental, particularly those involving external sparks or potentially distracting visual effects.
Still, the application offers an interesting glimpse into how Audi is thinking about the emotional appeal of electric cars. Whether enthusiasts actually want their EVs to smell, vibrate, and shoot sparks is a whole other discussion.
