Tesla has produced a new guide to familiarize yourself with the sounds that its electric cars make. Even though EVs are quieter than gasoline-powered vehicles, it doesn’t mean they are noiseless.

Electric cars not only reduce pollution from harmful emissions at the tailpipe, but they also reduce noise pollution.

That’s a benefit that is often underappreciated, but a reduction in noise pollution has been associated with a reduction in stress, which is a silent killer in our society.

Studies have even directly linked electric cars and a reduction in stress due to the noise reduction.

However, for some, the lack or reduction of noise in electric vehicles is a downside. Many gearheads like the noise of engines and feel like the lack of noise in an electric car is a downside to the driving experience.

While electric vehicles do make less sound than gasoline-powered vehicles, especially when they accelerate, they do still make sounds, and all electric motors make different ones.

Interestingly, Tesla decided to help its owners familiarize themselves with the sounds that their electric vehicles make by putting a guide of “Normal Operating Sounds.”

Electrek found the guide released on Tesla’s support website last week:

While your Model 3 is incredibly quiet, it is not completely silent. There are some sounds your vehicle makes as part of its normal daily operation and are not a cause for concern. Below is a list of possible normal operating sounds your vehicle could make based on where the sound is coming from:

In the guide, Tesla includes sounds that it considers normal inside of its vehicles, like this “Humming, Whirring, or Wooshing Sound” when driving:

The automaker did start the guide with a quick warning:

This is a general guide to help you understand common sounds you may hear from your vehicle during its normal course of operation. It is not a diagnosis of your vehicle, and does not represent a comprehensive list of normal sounds you may hear. If you wish to schedule an appointment with Tesla Service for any reason, contact your local service center.

Here are some of the other “sounds of a Tesla”:

Vibration Sound/Feeling in Steering Wheel

This sound is specifically caused by the steering wheel vibrating because of Lane Departure Warning alerts.

Whirring or Whining While Driving at Low Speeds (if Equipped with Pedestrian Warning System)

That’s just the pedestrian warning sound that Tesla is forced to add as part of regulations regarding “quiet vehicles.”

Noise in Driver’s Footwell When Brake is Pressed

This sound is related to the “Hold” function that may initiate after coming to a stop.

Tesla has also included sounds that you may hear when the vehicle is parked.

Clicking, Clunking, or Thumping Sound From Floor of Vehicle

This sound has an interesting origin. Tesla writes in the guide:

When Parked, Model 3 opens the HV Battery contactors to help conserve energy. This sound occurs when you start the vehicle after it’s been Parked, and signifies that the high voltage contactors are closing the circuit between your vehicle and the Battery.

Creaking or Cranking From the Tires or Brakes

As the name of the sound indicates, this is as simple as the brakes being released.

Banging, Clunking, Popping, or Thumping Noise While Supercharging

This sound while supercharging apparently can be explained by the metal components in your vehicle’s battery pack naturally expanding or contracting to accommodate ambient temperature changes.

Mahle CEO Arnd Franz says hydrogen will fail without fossil fuels

Mahle CEO Arnd Franz says hydrogen will fail without fossil fuels

Echoing the words of hydrogen critics everywhere, Mahle Chairman Arnd Franz says that building out a hydrogen infrastructure won’t be possible without “blue” H made from fossil fuels.

If you’re not familiar with Mahle, they’re a legendary engineering firm perhaps best known (in my circles, at least) for their high-performance piston designs. But they’re big time, and their expertise extends far beyond the reciprocating machinations of the VR38DETT.

With that in mind, I don’t want to misrepresent the words of the esteemed Mr. Franz, who claims to be bullish on H’s prospects as a fuel. What I intend to do here, then, is shine a light on the space between Franz’ lines, read whatever’s in there, and then ask if you see what I see.

“We can’t achieve any CO2 emission reductions if you use natural gas or any other fossil sources to produce hydrogen,” Franz is quoted saying. “Today, the overwhelming portion of hydrogen production worldwide is around 90 million tons. That number is going to go up to 130 million tons until 2030. Currently, we have a flourishing and growing portion of that being more sustainable. By more sustainable, I mean blue and, eventually, green hydrogen. In our opinion, [blue hydrogen production is needed] to get the infrastructure going in order to get the ecosystem.”

I read that as saying that, today, there are no carbon emissions reduction benefits from using hydrogen as a fuel, because the overwhelming majority of those 90 million tons is being produced by natural gas and fossil fuels.

What’s more, everyone involved seems to trying to justify that with claims that fossil-generated hydrogen is some kind of “necessary evil” (my words) to build out a viable H ecosystem. See if you hear it, too.

“We will fail [with hydrogen technology] if we don’t use blue hydrogen,” Franz clarified. “Right now, hydrogen is produced from fossil sources with carbon capture, meaning we don’t let the carbon reach the atmosphere. Eventually, we need to get to wind and solar as the sources of energy to make hydrogen, and we believe the US has a really impressive program [thanks to] subsidies from the Inflation Reduction Act.”

And, if you believe in those good intentions – well, read a little about Chevron’s history of using patent law to block the development of nickel-hydride EV batteries in the 90s and early aughts and see if that changes your mind.

Nothing we don’t already know

MAN Trucks says hydrogen will never work, bets the farm on batteries

Earlier this year, MAN trucks’ CEO Alexander Vlaskamp told reporters that it was, “impossible for hydrogen to effectively compete with battery electric trucks.”

He was right then, and he’s still right now. “It’s one thing to have the technology and another thing for the technology to be viable,” Vlaskamp told the magazine Expansión (translated from Spanish). “Green hydrogen is not available for transportation and there is no point in switching from diesel to hydrogen if the energy source is not sustainable.”

Even so, MAN continues to develop hydrogen technology with surprising openness. And, by “openness,” I mean: he comes right out and says he’s only developing hydrogen tech to absorb subsidy money.

That’s my take, anyway. Let us know what you think of my “reading between the lines” of Mahle’s statement in the comments.

UAW tells Stellantis workers to prepare for a fight, and vote for strike

UAW tells Stellantis workers to prepare for a fight, and vote for strike

The UAW union’s Stellantis Council met yesterday to discuss the beleaguered carmaker’s “ongoing failure” to honor the agreement that ended the 2023 labor strike, and their latest union memo doesn’t pull many punches.

It’s not a great time to be Stellantis. Its dealers are suing leadership and threatening to oust the company’s controversial CEO, Carlos Tavares, as sales continue to crater in North America, it can’t move its new, high-profile electric Fiat, and it’s first luxury electric Jeep isn’t ready. And now, things are about to get bad.

In an email sent out by the UAW earlier today (received at 4:55PM CST), UAW President Shawn Fain wrote, “For years, the company picked us off plant-by-plant and we lacked the will and the means to fight back. Today is different. Because we stood together and demanded the right to strike over job security—product commitment—we have the tools to fight back and win … We unanimously recommend to the membership that every UAW worker at Stellantis prepare for a fight, and we all get ready to vote YES to authorize a strike at Stellantis.”

The dispute seems to stem from Stellantis’ inability to commit to new product (and continued employment) at its UAW-run plants and other failings to meet its strike-ending obligations. This, despite a €3 billion stock buyback executed in late 2023.

I’ve included the memo, in its entirety, below. Take a look for yourself, and let us know what you think of the UAW’s call for action in the comments.

Kia EV9 GT caught with an active spoiler for the first time [Video]

Kia promises the new EV9 GT will have “enormous power,” but that’s not all. For the first time, the Kia EV9 GT was caught with an active spoiler, giving us a sneak peek at potential new upgrades.

The brand’s first three-row electric SUV is already making its presence known in the US, helping push Kia to back-to-back record sales months. Meanwhile, a more powerful, sporty variant is on the way.

Kia confirmed the EV9 GT will top off the electric SUV’s lineup in April. Packing “enormous power,” the high-performance GT model can accelerate from 0 to 62 mph (0 to 100 km/h) in 4 secs.

With a “high-output” dual-motor (AWD) system, the EV9 GT can quickly pick up speed despite weighing over 5,000 lbs.

Kia also equipped it with other high-performance features, such as a reinforced suspension and electronic braking system, for better control and stability.

We’ve already caught a glimpse of the performance electric SUV out testing, revealing aggressive new bumpers and wheels. Now, a new design feature has been spotted.

Kia EV9 GT could come with an active rear spoiler

The latest video from HealerTV shows the EV9 GT with what appears to be an active spoiler. As the reporter noted, it could be similar to the one spotted on the Genesis GV70 Magma.

Tesla’s Model X also used to come with an active spoiler until it was dropped a few years back. Although the GT model was spotted with one, Kia could just be testing new features, so don’t get too excited yet.

Earlier this week, a video from HealerTV showed the front row of the EV9 GT, comparing it to the current GT-Line model.

Several differences can be immediately noticed, including a more aggressive, all-black design with a yellow stripe down the center of the seat.

Kia is set to launch the EV9 GT in early 2025. It will rival other performance SUVs like the Tesla Model X Plaid.

Although prices have yet to be confirmed, the GT model is expected to sit above the current GT-Line at $73,900. In comparison, Tesla’s Model X Plaid starts at $94,990 and can sprint from 0 to 60 mph in 2.5 secs.
