There is nothing better than hearing the roar of a powerful engine, according to many sports car enthusiasts.

When the likes of Audi, BMW and Mercedes-Benz release electric versions of some of their highly desired sports cars, the sound of the engine may be too quiet for some. Clearly they will not be attractive to the market that they are aiming for. Audi service is vital for optimum performance of the Audi cars.

Safety

That is not the main issue however. The element of safety must also be heavily considered. When crossing the road or driving, you are able to judge if there is an oncoming car through the sound of the engine. If a car is silent with no engine noise, there is a huge increase in danger. Sight alone will have to be used in order to sense the oncoming danger. Surely that will prove not be enough in today’s dangerous environment.

What Audi plan to do about it

Audi’s method of conquering this problem is to provide a synthetic engine noise to the company’s new line up of e-Tron vehicles. Rudolf Halbmeir, one of Audi’s head engineers has been put in charge of the project. The aim is to recreate the sound of a sports car, working intelligently with the engine speed and the vehicle behaviour. The sound will play out through a 40 watt loudspeaker which will fit underneath the car.

Ralf Kunkel, the Head of Acoustics at Audi has explained how the project has been an ongoing process for a number of years. “Good sound design is a complex endeavour. We have gathered a lot of expertise over the years. We have also learned how to amplify pleasant frequencies and to suppress unpleasant noises.”

Axel Brombach, a speaker expert who is working on the project said the Audi R8 e-tron sounds sports and futuristic. He said “Out of the building and to the street. A red Audi R8 e-tron pulls up around the corner, purring gently. But when Rudolf Halbmeir taps the gas pedal, the purr turns into a cultivated growl. Though not unlike an elegant V8, it is especially pure and nuanced, and is shrouded in bright and innovative overtones. The Audi R8 e-tron certainly sounds like a sports car, but also one-of-a-kind and very futuristic.”

The sound produced from the electric vehicle new speaker system will be enough to warn nearby cyclists and pedestrians. Noise pollution will be increased but safety, which is more important, will be enhanced.
