NHTSA says your Tesla can’t be this quiet starting Sept., 2019
We at Teslarati are all in favor of making vehicles as safe as possible. Indeed, in our research and analysis of Teslas, we were proud early on in 2013 when the National Highway Traffic Safety Administration (NHTSA) awarded the Tesla Model S a 5-star safety rating, not just overall, but in every subcategory without exception. It was so safe, in fact, that the all-electric sedan broke the testing equipment at an independent commercial facility. Fast-forward to 2015. The Model X was the first SUV to be five-star in every category, according to Tesla CEO Elon Musk. It even won the prestigious Golden Steering Wheel (Das Goldene Lenkrad) award for best SUV this year.
Safety is important and should be primary to any driving situation. It should prevail over luxury features, style, and even comfort. However, a new NHTSA regulation that purports to target safety in its language is little more than a superficial gesture within a larger framework of driver, passenger, and pedestrian concerns.
Federal Motor Vehicle Safety Standard No. 141, which will begin on September 1, 2019, requires all newly manufactured hybrid and electric light-duty vehicles to make an audible noise at speeds below 19 mph. The sound requirement has been designed to help pedestrians who are blind, have low vision, cyclists, and other pedestrians to detect the presence, direction, and location of hybrids and EVs traveling at low speeds. At higher speeds, the sound alert will not be required because other factors, such as tire and wind noise, seem to provide adequate audible warning to pedestrians and will not be the subject of this regulation.
“We all depend on our senses to alert us to possible danger,” said U.S. Transportation Secretary Anthony Foxx. “With more, quieter hybrid and electrical cars on the road, the ability for all pedestrians to hear as well as see the cars becomes an important factor of reducing the risk of possible crashes and improving safety.”
Creating a social environment in which all individuals — especially those with disabilities, underrepresented groups, children, and the elderly — are physically and psychologically welcomed and safe is absolutely paramount to a healthy community. Manufacturers and drivers of hybrids and EVs do have a responsibility to contribute to such an environment.
Yet, clearly, we have a generation who has been accustomed to the sounds and smells of internal combustion engines. Wouldn’t driver and pedestrian education be a more efficacious way to ensure that hybrids and EVs do not pose a safety threat? Daniel Kahneman’s (2013) work, Thinking Fast and Slow, suggests that innovative products require a higher degree of learning than existing products. Education to help EV drivers and individuals who do not have personal access to hybrids and EVS, thus, who have not built in conscious mechanisms toward the awareness of hybrids and EVs in traffic, would have longer lasting and more permanent results.
Making the case for educating pedestrians
As the general population increases its awareness of the risks of pollution to both health and the environment, the internal combustion engine has become less desirable. As a result, battery-powered, fuel-cell electric, and hybrid vehicles are technologically viable alternatives to the internal combustion engine. And they’re beginning to take on a significant segment of the U.S. vehicle market.
Essentially, an internal combustion engine works like a cannon. The sound that results is formidable and part of our collective U.S. psyche. It is ingrained in our psychological expectations of what an engine should be. Electric motors, however, make very little noise compared with an internal combustion engine. Research on the safety implications of quiet electric vehicles has mostly focused on pedestrians’ acoustic perception of EVs and suggests that EVs compromise traffic safety. However, Cocran & Krems‘ 2013 research determined that, based on gained individual experience, drivers adjust their evaluation of noise-related hazards. Some statistical observation studies in literature indicate that hybrid or EV drivers intend to be more careful, less risk takers in traffic (Horswill and Coster 2002). Thus, it makes sense to increase the awareness factors for everyone — EV drivers and pedestrians — to create more robust safe traffic situations when EVs are added to the vehicle mix.
Adding to the sound mix
Principles to increase awareness of hybrids and EVs have generally focused on alerts, or sounds that indicate the presence of an EV. Other principles, such as orientation mechanisms, which make it possible to determine where the vehicle is located, roughly how fast it is going, and whether it is moving toward or away from the listener, extend beyond mere white or overt noises.
Education transcends any of these physical additions to a hybrid or EV. Hybrid and EV drivers as well as pedestrians should be exposed to new conceptual thinking about the place of EVs in traffic situations. Alongside the new federal safety standard that requires low speed noise, hybrid and EV automakers can build in specific educational materials to prepare their consumer base for new driving situations, which will continue to add safety awareness. With access to multiple new technologies, drivers could have multimodal educational opportunities.
- Audio systems could provide periodic, random reminders to increase driver awareness of pedestrians and cyclists in slow speed situations.
- Automakers could require that drivers work through a series of interactive online tutorials that accentuate driver understanding of slow speed safety adaptations with hybrids and EVs.
- Traditional print manuals should include dedicated sections that address slow speed driver safety decision making.
- Before-driving checklists should include explicit instruction in slow speed situations and the possibility of pedestrian interactions.
Consumer safety groups can also assume responsibility for educating their constituents about new needs for pedestrian and cyclist awareness.
- Cyclist advocacy organizations can provide seminars to their members during events to increase strategies for hybrid and EV slow speed situations.
- Existing support groups for persons with visual impairment can add workshops about hybrid and EVs to empower them to anticipate potential slow speed traffic situations.
- Minimal training standards for service animals could include special animal recognition of hybrid and EVs.
- Traditional and highly respected elderly advocacy organizations like AARP could provide print and online materials to help a generation who grew up with internal combustion engines to accommodate strategies to recognize hybrids and EVs in traffic.
Yes, adoption and diffusion of new innovations can be a long-term, complicated process. Airbags, child safety features, exhaust gas hazard, seat belts, and driver assist technologies currently provide hybrid and EV drivers with a toolkit of pedestrian safety measures. But we want more than to prevent what NHTSA says is about 2,400 pedestrian injuries each year that occur during low speed hybrid or EV/ pedestrian interactions. We want to create a cultural climate in which a social vehicular knowledge base extends well beyond the internal combustion engine.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.
In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:
“It’s like driving an office building.”
The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.
Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.
“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.
Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.
Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.
Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.
Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.
Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.
Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.
Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.
Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.
The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla expands its mass-market color palette in the U.S.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads.
Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.
Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.
Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.
The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.
Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.
Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
