Audi’s patent for electric cars: artificial turbo lag, sparks, and engine vibrations

Audi’s patent application describes unusual technical solutions for the driving experience in electric vehicles. According to media reports, it focuses on systems designed to generate or enhance sounds, vibrations, visual effects, and smells based on the vehicle’s condition. This application is not yet a granted patent and does not mention any planned commercial use.
A key approach involves the targeted transmission of actual engine noises and vibrations into the cabin. To this end, Audi describes so-called vibration transfer elements, such as rigid steel hollow profiles, which connect the electric motor to other parts of the vehicle. Reduced sound insulation for the drive system is also intended, so that its operating noises become more noticeable. Unlike artificially created engine sounds, this method utilizes the mechanical vibrations of the electric drive itself.
Other elements of the patent application relate to replicating typical characteristics of internal combustion engines. A clutch could separate the electric motor from the drive train, allowing it to spin at high speeds and produce corresponding noises even when the vehicle is stationary. Additionally, Audi describes an electronic control system for simulated gear shifts, virtual gear ratios, and a artificial turbo lag, in which the increase in power is deliberately delayed. Temporary activation of additional power or torque via button press or AI-driven control is also mentioned.
The described optical effects are particularly unusual. Audi mentions things such as electrical arcs between electrodes and a device that could generate sparks through controlled contact of a metal part with the road surface. Other concepts include dynamic exterior lighting, changeable vehicle colors, and projections in the edge area of the windshield intended to convey acceleration and speed through blur or distortion effects. Animated displays on the front of the vehicle are also included in the patent description.
In addition, the patent application explores situational scenting of the interior. While calming scents could be released during traffic jams, stimulating odors are intended for sporty driving modes. As an example, the description mentions a scent meant to resemble electric toy trains, which is referred to there as “electrosmog.” The scent release is supposed to be controlled via appropriate storage containers and a system that adjusts based on driving conditions.
The published patent application includes ten claims in total. Two independent claims relate to the transmission of vibrations or sound, as well as the generation of visual effects depending on driving conditions. No specific Audi model, launch date, or cost associated with a potential implementation is mentioned in the published application.
