The future electric Porsches with false sound exhausts?


To continue to bring to life the mythical sound of its gasoline engines, Porsche is developing a fictitious loudspeaker exhaust for its electric vehicles.

The automobile has a close link with the noise of its thermal engine, and even more so in the case of sports models. The electric car bringing silence, or limiting to aerodynamic noise and hissing from the engine, the lack may bother some.

Some manufacturers had already offered systems inside these vehicles. It’s the case interior speakers as in the interior of the Mazda MX-30 sounding (a bit) like a gasoline car.

Fictitious exhausts

Porsche wants to go further. Stronger than in the passenger compartment, the Zuffenhausen firm is considering making its electrics roar outside. The information is based on a patent filed in Germany, to respond to the lack of “Emotional character”.

The manufacturer has developed a fictitious exhaust Under the form “From one or more outputs », arranged in the back of its electric cars. For a more melodious sound, Porsche add speakers and a titanium-based sound box playing the amplifier. The result would create “Realistic exhaust noises (ie combustion-type)”.

We are not surprised that the initiative comes from the manufacturer of the 911, whose “flat-six” engine has a recognizable signature in all of them.

A sound warning device already compulsory

Namely, European regulations already require electric cars to make noise. Too silent and undetectable by other users, they must emit a noise under 20 km / h. The sound should exceed 56 decibels, without exceeding the threshold of 75 dB. This device has been mandatory since July 1, 2019 on new models, and 2021 on all new cars.

The fictitious Porsche exhausts could thus play the role of warning, in addition to offering a sound signature above 20 km / h. Case to be continued on the next electric Porsche Macan or the hypothetical future electric Cayman.
