Tesla’s electric cars are already among the safest vehicles on the road today with their impressive safety ratings. But even the best cars still have room for improvement, and one can count on Tesla to be the manufacturer that will do what it can to make its already-safe vehicles even safer. An example of this could be found in a recently published patent that describes a “crash can” that can help protect occupants better in the event of a collision.

The patent, titled “ADVANCED THIN-WALLED STRUCTURE FOR ENHANCED CRASH PERFORMANCE” describes a specific design for a “crash can,” a thin-walled metal structure that is built into the crash zones of a vehicle. These metal structures are built to absorb the energy of an impact, and are designed to deform in a stable manner during events such as a crash. Crash cans are typically a square, single-cell tube directly mounted to the front of the frame of the vehicle. 

Tesla’s crash can patent takes the same concept but raises it up a couple of notches higher. Instead of using a simple square, single-cell tube, Tesla’s patent describes a “multi-cell structure that includes at least four hollow cuboids.” The four walls of the hollow cuboids meet at 90-degree angles and at least two of the cuboids share a wall. Tesla describes its design in the section below. 

“In some embodiments a crash can for a vehicle includes a multi-cell structure that includes a hollow cuboid and four hollow isosceles trapezoidal prisms. The hollow cuboid has four walls and the four hollow isosceles trapezoidal prisms each have a long base, a short base, and two legs. The four hollow isosceles trapezoidal prisms are arranged around the hollow cuboid such that the long base of each hollow isosceles trapezoidal prism shares one of the walls of the hollow cuboid.”

This updated design, while seemingly a minor change, actually improves the safety of a vehicle during a crash. According to Tesla, the crash can design in its recently-published patent provides a more stable deformation process. This increases the amount of energy that can be absorbed in a collision. 

“One advantage of the various embodiments of the crash cans disclosed herein is that the multi-cell structure of the crash cans provides a more stable form of plastic deformation when the crash can is subject to the force of a collision relative to a single cell (tube) structure. Further, the various geometries described herein may further provide more stable plastic deformation relative to conventional geometries. As described herein, plastic deformation is the process of absorbing energy when the crash can is subject to a collision. Various exemplary crash cans provided herein increases plastic deformation, and thus the amount of energy absorbed, by increasing the probability that the crash cans buckle in a progressive manner. Thus, the multi-cell structure of the exemplary crash cans increases the probability that when subjected to axial force the crash cans will buckle in a stable top-down, progressive folding of the structure.

“Increasing plastic deformation in this manner grants the multi-cell crash can several advantages. For example, increasing plastic deformation in turn increases the amount of energy that will be absorbed during a collision, resulting in lower deceleration for the occupant(s) and critical components of a vehicle involved in a collision. This, in turn, results in an overall safer experience for the occupant(s) and critical components, providing for a lower chance of injury or damage. Additionally, increasing the probability that the multi-cell crash can buckles in a stable manner increases the predictability of how the crash can will react when subject to a collision, which in turn increases the predictability of how the rest of the vehicle will react. This allows for greater predictability of what an occupant will experience and allows for more precise planning on how to keep the occupant safe.”

Among the carmakers in the auto segment today, Tesla is arguably the most obsessive when it comes to its vehicles’ safety. Each one of Tesla’s electric cars has performed well in crash tests, with the Model X SUV proving to be near-impossible to topple, and the Model 3 acing the safety tests of the NHTSA, Euro NCAP, ANCAP, and even the IIHS. With improvements such as those described in its recently-published “crash can” patent, Tesla’s electric cars today, as well as its upcoming vehicles, could prove even safer.

Tesla has confirmed the rollout of a new, critical feature that is coming to the United States for the first time.

However, the Cybertruck will unfortunately miss out on it.

Tesla has a distinct advantage among many automakers as their Over-the-Air updates make their vehicles better over time. While many automakers have the ability to roll out new features through these updates, Tesla has been shown to be one of the companies that can truly make things significantly better with their cars.

A new feature coming to the United States and now rolling out is Adaptive Headlights. This feature will be applied to Model S, Model 3, Model X, and Model Y vehicles with the proper hardware.

Adaptive Headlights are different than your typical auto highbeams in the way that they can dim certain pixels of the bulb to keep visibility for the Tesla driver high, while eliminating glare for those who are in oncoming cars:

For the first time, Tesla is rolling out the feature to these vehicles in the United States. European Tesla owners were able to use the function several months back, but it was pending approval in the U.S.

At first, Tesla VP of Vehicle Engineering, Lars Moravy, said that the Cybertruck would have this feature. However, in late February, he confirmed that he was incorrect and the all-electric pickup will not have the ability to get Adaptive Headlights, as the company could not fit the correct hardware in the Cybertruck’s module:

The feature certainly makes visibility better for everyone on the road and will improve overall safety while eliminating the pesky and annoying feeling of being blinded by high beams.

The Adaptive Headlight feature for Tesla is part of the company’s Spring Update for 2025.

Tesla Model 3 wins ‘most economical EV to own’ title in new study

The Tesla Model 3 has captured another crown in a recent study showing the most cost-effective EVs

The Tesla Model 3 recently captured the title of “most economical electric vehicle to own” in a new study performed by research firm Zutobi.

Perhaps one of the biggest and most popular reasons people are switching to EVs is the cost savings. Combining home charging, lower maintenance costs, and tax credits has all enabled consumers to consider EVs as a way to save money on their daily drivers. However, there are some EVs that are more efficient and cost-effective than others.

Tesla police fleet saves nearly half a million in upkeep and repair costs

Zutobi‘s new study shows that EV cost-effectiveness comes at different levels. For example, some cars are simply better than others on a cost-per-mile basis. The study used a simple process to determine which EVs are more cost-effective than others by showing how much it would cost to drive 100 miles.

National averages for energy rates have been used to calculate the cost as they widely vary from state to state.

The Rear-Wheel Drive Tesla Model 3 was listed as the most economical vehicle in the study:

“The standard Tesla Model 3 is the most economical electric vehicle to drive in 2025. With a usable battery capacity of 57.5 kWh and a real-world range of 260 miles, it costs just $3.60 to drive 100 miles. That translates to an impressive 2,781 miles per $100 of electricity—making it the most efficient choice for EV owners nationwide.”

It had an estimated cost of just $3.60 to drive 100 miles.

The Tesla Model 3 Long Range All-Wheel Drive was second, the study showed:

“Next is the Long Range version of the Model 3, which offers extended range and dual-motor all-wheel drive. With a larger 75 kWh battery and 325 miles of range, the cost to drive 100 miles is slightly higher at $3.75, still equating to a strong 2,665 miles per $100.”

This version of the Model 3 had a price of just $3.75 to drive 100 miles.

In third, the BMW i4 eDrive35 surprised us with a cost of just $4.12 to drive 100 miles:

“Rounding out the top three is the BMW i4 eDrive35, with a 67.1 kWh battery and a real-world range of 265 miles. Drivers can expect to pay $4.12 per 100 miles, which still allows for 2,429 miles per $100—a solid choice for those seeking luxury and efficiency.”

Several other Teslas made the list as well. The Model 3 Performance ($4.34 per 100 miles) was sixth and tied with the Volkswagen ID.3 Pure, the Tesla Model S Long Range ($4.35 per 100 miles) was 8th, and the Tesla Model Y Long Range was ninth ($4.36 per 100 miles).

Tesla is offering new discounts on Cybertruck units in inventory, giving customers a chance to snag a unit of the all-electric pickup for a slight reduction in price. Some are even coming with additional perks to make the offer even sweeter.

Tesla is now offering up to $10,550 off of Cybertruck inventory units across the United States. This is up from previous discounts of $6,000 on inventory Cybertrucks, and it will apply to 2024 model year vehicles.

Non-Foundation Series Cybertrucks are getting up to $10,550 off of their original prices, while Foundation Series pickups are getting up to $10,000 off. These are great deals and should help clear out some inventory from last year’s models.

Additionally, Foundation Series Cybertrucks purchased will receive free lifetime Supercharging, another great addition to make the deal even better than the $10,000 off.

The move comes as Tesla is still ramping Cybertruck production and is hoping to stimulate some additional demand for the vehicle, as it is holding on to these units. These are not Demo Drive units that have been driven by any number of people who were looking for a quick test drive.

Tesla launched a new configuration of the Cybertruck just last week with the Long Range Rear-Wheel-Drive, which undercuts the All-Wheel-Drive option by roughly $10,000.

Tesla released the Cybertruck RWD to make the AWD look like a deal

However, Tesla stripped the vehicle of several features, including Air Suspension, a tonneau cover, and interior features. For example, the Rear-Wheel-Drive trim of the Cybertruck has textile seats and no rear touchscreen, two things that come standard in the other trim levels.

The Cybertruck is the best-selling electric pickup in the United States, outperforming formidable competitors like the Ford F-150 Lightning and Chevrolet Silverado EV. However, Tesla is still working to get the vehicle to a lower price point that makes it more accessible to consumers, as its current pricing is a far cry from what was intended.
