The advanced safety features are not just technological marvels, but they play a crucial role in making EVs efficient, eco-friendly, reliable, and secure for drivers and passengers. As EV models evolve, evidence shows that they are safer than traditional internal combustion engine (ICE) vehicles. According to a study by the Insurance Institute for Highway Safety (IIHS), the likelihood of injury in crashes involving EVs is lower for passengers than those in gasoline and diesel-fueled vehicles. The IIHS compared claims data from the electric and ICE versions of nine vehicles from model years 2011 to 2019, finding that injury claim rates for EV drivers and passengers were over 40% lower than for their ICE counterparts.
EV Magazine takes a look at the top 10 safety features that keep car occupants guarded:
Autonomous Emergency Braking (AEB) is a safety feature that prevents collisions by detecting obstacles and automatically applying the brakes. This advanced technology enhances vehicle safety by intervening when drivers fail to react quickly, reducing the risk of accidents and protecting occupants and pedestrians.
Lane Keeping Assist (LKA) and Lane Departure Warning (LDW) are advanced safety features that help keep vehicles within their lanes. LKA provides corrective steering to maintain lane position, while LDW alerts drivers with warnings if they unintentionally drift out of their lane, enhancing overall driving safety.
A safety feature that immediately alerts emergency services in the event of a crash. Upon detecting a collision, ACN transmits crucial information, such as location and impact severity, ensuring rapid response and assistance, which can significantly improve outcomes for vehicle occupants.
A crucial component in electric vehicles is overseeing battery performance and safety. It monitors and manages the battery''s state, including charging, discharging, temperature, and health, ensuring optimal efficiency, longevity, and protection against overcharging or overheating.
These are advanced safety features designed to enhance driver awareness. Blind Spot Monitoring alerts drivers to vehicles in adjacent lanes that may be out of view. At the same time, the Rear Cross Traffic Alert warns of approaching traffic from the sides when reversing, reducing the risk of collisions.
Each is a crucial safety feature in modern vehicles. They use advanced materials and engineering techniques to fortify the vehicle's body, absorbing and distributing impact forces during a collision. This design significantly reduces injury risk to occupants by maintaining the integrity of the passenger compartment.
They are critical safety features in electric vehicles. They automatically cut off the high-voltage battery during a crash or fault, preventing electric shock and fires. The feature ensures that high-voltage components are only accessible when the system is safe, protecting occupants and emergency responders.
These feature updates allow wireless delivery of software updates, firmware, or configuration changes to devices like smartphones, vehicles, and IoT gadgets. This technology ensures that devices stay current with the latest features, security patches, and performance enhancements without needing physical connections or manual intervention.
These features use sensors, cameras, and AI to identify pedestrians near vehicles and alert drivers to potential collisions. These systems enhance safety by providing real-time warnings and, in some cases, automatically applying brakes to prevent accidents, protecting pedestrians and drivers.
It regulates the temperature of electronic devices, batteries, and machinery to prevent overheating and ensure optimal performance. By using components like heat sinks, fans, and liquid cooling, these systems maintain efficiency, extend lifespan, and enhance safety in various applications, from computers to electric vehicles.
These features enhance vehicle safety by preventing wheel spin and maintaining stability during acceleration and cornering. Traction control adjusts power to wheels, while stability control applies brakes to specific wheels, helping drivers maintain control in slippery or challenging conditions, reducing the risk of injury.

DETROIT (AP) — The head of the National Transportation Safety Board expressed concern Wednesday about the safety risks that heavy electric vehicles pose if they collide with lighter vehicles.
The official, Jennifer Homendy, raised the issue in a speech in Washington to the Transportation Research Board. She noted, by way of example, that an electric GMC Hummer weighs about 9,000 pounds (4,000 kilograms), with a battery pack that alone is 2,900 pounds (1,300 kilograms) — roughly the entire weight of a typical Honda Civic.
"I''m concerned about the increased risk of severe injury and death for all road users from heavier curb weights and increasing size, power, and performance of vehicles on our roads, including electric vehicles," Homendy said in remarks prepared for the group.
The extra weight that EVs typically carry stems from the outsize mass of their batteries. To achieve 300 or more miles (480 or more kilometers) of range per charge from an EV, batteries have to weigh thousands of pounds.
Some battery chemistries being developed have the potential to pack more energy into less mass. But for now, there''s a mismatch in weight between EVs and smaller internal combustion vehicles. EVs also deliver instant power to their wheels, making them accelerate faster in most cases than most gas-powered cars, trucks and SUVs.
Homendy said she was encouraged by the Biden administration''s plans to phase out carbon emissions from vehicles to deal with the climate crisis. But she said she still worries about safety risks resulting from a proliferation of EVs on roads ands highways.
"We have to be careful that we aren''t also creating unintended consequences: More death on our roads," she said. "Safety, especially when it comes to new transportation policies and new technologies, cannot be overlooked."
Homendy noted that Ford''s F-150 Lightning EV pickup is 2,000 to 3,000 pounds (900 to 1,350 kilograms) heavier than the same model''s combustion version. The Mustang Mach E electric SUV and the Volvo XC40 EV, she said, are roughly 33% heavier than their gasoline counterparts.
"That has a significant impact on safety for all road users," Homendy added.
The NTSB investigates transportation crashes but has no authority to make regulations. For vehicles, such authority rests largely with the National Highway Traffic Safety Administration.
Even apart from EVs, the nation''s roads are crowded with heavy vehicles, thanks to a decadelong boom in sales of larger cars, trucks and SUVs that''s led to extreme mismatches in collisions with smaller vehicles. But electric vehicles are typically much heavier than even the largest trucks and SUVs that are powered by gasoline or diesel.
Michael Brooks, executive director of the nonprofit Center for Auto Safety, said he, too, is concerned about the weight of EVs because buyers seem to be demanding a range of 300 or more miles per charge, requiring heavy batteries.
Setting up a charging network to accommodate that may be a mistake from a safety perspective, Brooks said.
"These bigger, heavier batteries are going to cause more damage," he said. "It''s a simple matter of mass and speed."
Brooks said he knows of little research done on the safety risks of increasing vehicle weights. In 2011, the National Bureau of Economic Research published a paper that said being hit by a vehicle with an added 1,000 pounds increases by 47% the probability of being killed in a crash.
He points out that electric vehicles have very high horsepower ratings, allowing them to accelerate quickly even in crowded urban areas. "People are not trained to handle that type of acceleration. It''s just not something that drivers are used to doing," Brooks said.
Also, many newer electric SUVs are tall with limited visibility that poses risks to pedestrians or drivers of smaller vehicles, he said.
Sales of new electric vehicles in the U.S. rose nearly 65% last year to 807,000 — about 5.8% of all new vehicle sales. The Biden administration has set a goal of having EVs reach 50% of new vehicle sales by 2030 and is offering tax credits of up to $7,500 to get there. The consulting firm LMC Automotive has made a more modest prediction: It expects EVs to make up one-third of the new-vehicle market by 2030.
