Here are some electric vehicles that sound like warning pedestrians



The American rock band Linkin Park helps Mercedes-AMG bring the right sound for its electrical performance.

It's not a joke. At the Geneva Motor Show earlier this month, the Mercedes executives said the music group would develop the sound that would normally be silent battery-powered vehicles would do when driving to warn pedestrians.

That's because electric vehicles are pretty quiet and dangerous so, regulators say. Think of your cell phone or other electronic device – you won't hear much noise from it when it is running. Now think of your gas-powered car and all the vrooms, pipes and spins it does when the engine is on. An EV is more mobile-like than you would think.

As a large number of electric cars do so on the road, worry about the potential risk of silencing vehicles for pedestrians, cyclists and blind people to grow. The European Union has a new directive that requires all new electric and hybrid vehicles to give a good warning to pedestrians in 2021

. When traveling at speeds below 12 km / h, the cars must emit sound to give pedestrians a task that there is a vehicle also if they can't hear it. When it goes faster than that, the tires towards the road, wind resistance to the windshield and more the car more audible.

The United States set up a similar requirement for hybrid and all-electric vehicles, although it was delayed and took a while to haveh out the details. The National Highway Traffic Safety Administration will require that all electric cars (and hybrids) emit a sound while moving up to 18.6 mph by September 2020. (The United States decided on a faster speed limit based on arguments that cars are harder to hear until the "Move requirement will be phased in to give car makers time to change the vehicle, with 50 percent of cars required to sound a sound in September.

These new requirements mean companies like Mercedes-AMG and beyond the need to Coming up with artificial sounds, their electric cars will play while moving at slower speeds.At the deadline, many car companies already have sound in development and put them in cars. Waterproof outer speakers will emit the loud and clear.

The French car manufacturer Citroen introduced an electric compact car at the Geneva Motor Show this year, although it was just a concept vehicle, it included an "audio signature "who would play to comply with EU rules. The more playful tunes that oscillate based on the car's speed show how large the range of car companies must meet the requirements.

Here in the US, more automakers go electric. About 1 percent of car sales (and growing!) Are EV, which means that more of these quieter cars sneak up – if not intentionally – on people at the intersection or when they exit the parking lot. To meet the upcoming requirements, each car maker must have a sound plan if it has or will have an electric vehicle in its set-up.

Nissan Leaf is one of the more common and affordable EV discs. In the US, more than 14,700 cars were sold last year. It will emit these sounds as you move forward and backward, as if the sound is heard when a truck backs up – but with more musicality.

GM's Chevy Bolt is just behind Tesla's electricity sales. It reached 200,000 sales by the end of 2018, a few months after Tesla hit that marker. Since the Chevy & # 39; s hybrid Volt is no longer in production, the company focuses its electrical targets on the electrical bolt. The company developed its own AVAS sound, which stands for acoustic vehicle warning system.

Motorcycles are also included in this new rule, so Harley-Davidson's new LiveWire electric motorcycle shifts up with an original sound that emulates a "real" pig.

We went out to Tesla but didn't hear back about what its pedestrian warning sounds will sound like. We recently heard that with Sentry Mode, the cars can play loud music as anti-theft, but it uses the car's audio system, not an external speaker.

The silence is golden if you are not in an electric car. Then it's time to make some noise.
