What You'll Learn
Electric vehicle weight and performance
Electric vehicles (EVs) are generally heavier than their gasoline-powered counterparts. This is primarily due to the weight of their batteries, which can add hundreds of pounds or more to the overall weight of the vehicle. For example, the 2023 GMC Hummer EV weighs more than 9,000 pounds, with its battery pack alone weighing 2,900 pounds. This additional weight has raised concerns about safety, infrastructure impact, and performance.
Safety is a primary concern regarding EV weight. In crashes, the "baseline fatality probability" increases by 47% for every 1,000 pounds added to the vehicle's weight. With EVs weighing significantly more than similar-sized gasoline vehicles, the risk of severe injury and death in collisions increases, especially when heavier EVs collide with lighter vehicles. The extra weight of EVs can also affect braking performance and handling, potentially leading to more frequent and severe accidents.
The impact of EV weight on infrastructure has also been debated. Some argue that heavier EVs will accelerate the deterioration of roads, bridges, and parking structures. However, experts claim that the additional weight of EVs has little impact on infrastructure compared to heavy trucks, which cause the majority of damage on roadways.
In terms of performance, EVs have impressive acceleration capabilities due to their high horsepower ratings. This rapid acceleration, combined with their heavy weight, can be a dangerous combination, especially in residential areas. On the other hand, the absence of an engine in the front of the vehicle provides design flexibility, potentially allowing for the inclusion of additional crush space to mitigate the effects of weight in crashes.
While EV weight currently poses challenges, advancements in battery technology may alleviate these issues over time. Researchers predict that batteries will continue to increase energy density while maintaining or reducing weight, potentially resolving the weight problem in the future. In the meantime, policymakers and manufacturers must carefully consider safety measures, infrastructure adaptations, and performance enhancements to ensure the safe integration of EVs on our roads.

Electric vehicle weight and cost
Electric vehicles (EVs) generally weigh more than vehicles with internal combustion engines (ICEs). The average electric vehicle battery weighs about 1,000 pounds, adding hundreds of pounds to the overall weight of the vehicle. For example, the 2023 GMC Hummer EV weighs more than 9,000 pounds, with its battery alone weighing 2,900 pounds. In comparison, a similarly-sized ICE vehicle, the 2023 GMC Sierra, weighs less than 6,000 pounds.
The weight of an EV affects various factors, including range, insurance cost, and tire wear. EVs tend to have superior acceleration compared to ICEs, but their heavier weight leads to longer stopping distances, which can be a safety concern, especially when colliding with lighter vehicles. The heavier vehicle in a crash pushes the lighter one backward, resulting in higher forces on the occupants of the lighter vehicle. This increased weight can also impact infrastructure, with some experts expressing concern about the ability of rural roads and bridges to handle heavier passenger vehicles, including EVs.
The weight of EVs also has financial implications. While EVs do not pay gas taxes, which are a significant source of revenue for road maintenance, some states have imposed fees on these vehicles to offset the loss and pay for improvements. Additionally, the heavier weight and high-performance capabilities of EVs can result in higher insurance costs for their owners.
Despite the weight-related challenges, advancements in battery technology are expected to help mitigate some of these issues. Smaller batteries that store more energy and an expanding network of fast public chargers can reduce the need for long ranges. Furthermore, manufacturers can focus on designing vehicles with additional crush space in their front ends to help compensate for the extra weight in a crash, protecting both the occupants of the EV and those in lighter vehicles.
