Have you ever heard what a Tesla car sounds like when it’s running? If you’re one of the few people who has, you might notice something unusual about the engine noises emanating from the vehicle.
That’s because Tesla vehicles don’t have traditional internal combustion engines. Instead, they utilize electric motors that produce very little noise when in operation. The sound that they do make comes from the cooling systems, power electronics, and other ancillary components that support the electric powertrain.
Despite the fact that Tesla’s electric cars are ultra-quiet, the company is still working on improving the sounds that its vehicles produce. The goal is to create a pleasant and unique auditory experience that is also safe and informative for drivers and pedestrians.
Tesla has experimented with several different sounds over the years, each with its own characteristics and purpose. Here are some of the various sounds that you might hear if you’re driving or walking alongside a Tesla car.
1. Standard Operating Sounds
The most common noise that you’ll hear when a Tesla is driving at moderate speeds is a gentle whirring sound. This is the sound of the electric motors spinning, and it can become louder or softer depending on how fast the vehicle is traveling and how much power is being used.
But even when a Tesla is traveling at full speed, it’s still relatively quiet. At 60 mph, a Tesla Model S produces around 69 decibels of sound, which is about the same as a normal conversation. By comparison, a gasoline-powered car produces around 74 decibels of sound at the same speed.
2. Safety Alert Sounds
In some cases, Tesla adds additional sounds to its electric cars in order to improve safety. For example, when a Tesla is backing up, it emits a gentle high-pitched beep that serves as a warning to nearby pedestrians or cyclists. This sound is a legal requirement in certain countries, and it’s also a good way to prevent accidents.
Additionally, some Tesla drivers have reported hearing a faint whistling or hissing sound when their car is traveling at lower speeds. This is actually intentional: it’s the sound of the regenerative braking system working to slow down the car and recapture energy. By creating this audible feedback, Tesla helps drivers get a better sense of how much braking force is being applied and makes it easier to use the regenerative braking feature effectively.
3. Performance Sounds
Finally, Tesla has developed a few unique sounds that are designed to enhance the driving experience for drivers who enjoy high-performance vehicles. For example, the company offers “Ludicrous mode” on its Model S and Model X, which can propel the cars from 0 to 60 mph in under three seconds.
When Ludicrous mode is engaged, the Tesla emits a series of high-pitched, futuristic tones that are reminiscent of a science fiction movie. These sounds are completely artificial and are generated through the car’s speakers, but they add an extra layer of excitement and immersion to the driving experience.
So what do Tesla’s engine sounds actually sound like? The truth is, they’re incredibly varied and depend on a number of different factors. From the gentle whirring of the electric motors to the high-pitched warning beeps, each sound serves a unique purpose and contributes to the overall experience of driving a Tesla vehicle.
Of course, some drivers and pedestrians might prefer that electric cars were even quieter than they are now. But for Tesla, sound is a crucial part of its brand identity and an important element in creating a safe and enjoyable driving experience. So don’t be surprised if you hear some unusual noises coming from your electric vehicle the next time you take it for a spin.
