The Plastic Reality Of Tesla Cars

Electric vehicles (EVs) have driven the increased use of plastics in the automobile industry. Plastics are now used in the chassis and battery casings of vehicles, as well as in the charging infrastructure. According to the American Chemistry Council (ACC), plastics make up less than 10% of a vehicle's weight but account for approximately 50% of its volume. This means that while the average weight of vehicles has increased over time, the use of plastics has helped to improve fuel efficiency and reduce carbon emissions. Teslas, like other automobiles, contain plastic. In 2019, Tesla switched from using cowhide leather to vegan leather, which is made from plastic.

Plastic in Tesla's vegan leather

In 2019, Tesla announced that it would be transitioning all of its models' interiors from cowhide leather to a "vegan leather" material. This synthetic leather, also known as "Tesla Synthetic Material", is made from plastic, specifically polyurethane, and is not animal-sourced. The decision to adopt vegan leather was influenced by pressure from Tesla's shareholders and a desire to cater to environmentally conscious consumers.

While the use of vegan leather in Tesla's vehicles reduces deforestation and animal cruelty, it also introduces a trade-off in terms of fossil fuel usage. Plastic, being derived from fossil fuels, contributes to the consumption of global oil supplies. Additionally, concerns have been raised about the comfort and emissions of the vegan leather seats. Some customers have expressed a preference for real leather, cotton, or non-petroleum-based materials, citing comfort and the release of toxic volatile organic compounds (VOCs) as factors.

However, it is worth noting that the use of plastic in vehicles extends beyond just the vegan leather seats. Plastics are increasingly being incorporated into various components of vehicles, including electric vehicles (EVs). On average, plastics comprise less than 10% of a vehicle's weight but account for approximately 50% of its volume. This trend is particularly notable in EVs, where the heavier batteries drive automakers to use more plastic in parts like the chassis and battery casings to offset the weight.

Plastics also offer safety advantages in vehicles. Certain high-performance plastics can absorb four times the crush energy of steel, enhancing passenger protection in collisions. Additionally, plastics are more lightweight, contributing to improved fuel efficiency and reduced transportation costs and carbon emissions. As a result, the use of plastics in automobiles is driven by both functionality and sustainability considerations.

Plastic in EV batteries

Electric vehicles (EVs) are increasingly using plastic parts, with the average mass of plastics in a vehicle sold in the United States increasing by 16% from 2012 to 2021, to 411 pounds (186 kg). This increase in plastic usage is driven by the need to offset the weight of EV batteries, which are significantly heavier than internal combustion engines.

Plastics are also used in EV battery construction to reduce weight and improve safety. Plastic components incorporated into batteries include separators, gaskets, and casing components. Plastic casing components can be up to 35% lighter than metal alternatives and can absorb four times the crush energy of steel. This improves safety for passengers in collisions and helps to prevent damage to the basic cell unit from minor accidental impacts.

In addition to weight reduction and safety improvements, plastics are used in EV batteries for their electrical insulation, flame retardancy, and hydrolysis resistance properties. Polymer shields and connectors are important in autonomous vehicles as they remain neutral to the signals and waves sent and received by sensors.

While the shift to EV batteries has led to a reduction in the overall amount of plastic used in vehicles, the growing demand for lithium-ion batteries in EVs is expected to increase the use of plastic parts in the future.

Plastic in chassis and casings

The use of plastic in automobiles is becoming increasingly common, and it is an important material for the auto industry, particularly as electric vehicles (EVs) become more popular. Plastics are being incorporated into more vehicle components, such as the chassis and battery casings, to offset the weight of the heavier EV batteries.

In 2023, the American Chemistry Council (ACC) reported that plastics make up less than 10% of a vehicle's weight but account for approximately 50% of its volume. This means that despite the growing use of lightweight plastics in vehicles, the average vehicle weight has increased over time. This increase in weight can be attributed to two trends: passenger cars and light trucks are getting larger, and they are being equipped with more and more features.

The average mass of plastics in a vehicle sold in the United States increased by 16% from 2012 to 2021, reaching 411 pounds (186 kg). This amount of plastic is equivalent to less than 10% of the vehicle's weight but constitutes about 50% of its volume, leading to improved fuel efficiency and reduced transportation costs and carbon emissions.

Certain high-performance plastics used in vehicles can absorb four times the crush energy of steel, enhancing passenger safety in collisions. Additionally, these plastics are designed to withstand high temperatures from batteries, daily UV light exposure, and wear and tear.

While the specific details of plastic usage in Tesla's chassis and casings may not be publicly available, it is evident that plastics play a significant role in the construction of modern automobiles, including Teslas.

Plastic in fuel tanks

Tesla cars are 100% electric and do not have fuel tanks. They are powered by rechargeable battery packs and electric motors. The company has gained recognition for its groundbreaking electric cars that deliver impressive performance and contribute to a greener environment.

However, it is important to note that plastics are still used in the construction of Tesla vehicles. While the exact amount of plastic in a Tesla car may vary, plastics are commonly used in modern automobiles, including electric vehicles. On average, plastics make up less than 10% of a vehicle's weight but account for approximately 50% of its volume. This percentage is expected to increase as electric vehicles become more popular, as plastic is used in components like the chassis and battery casings.

In terms of materials, Tesla cars contain a variety of elements, including rare earth metals, steel, aluminium, plastic, and titanium. The company has also made efforts to incorporate more sustainable practices, such as switching from cowhide leather to "vegan leather," which is made from plastic. This synthetic material is more durable and reduces deforestation and animal cruelty, but it is still derived from fossil fuels.

While Tesla does not disclose the exact amount of plastic used in their fuel tanks or vehicles, it is safe to assume that plastics are used in various components, as is standard in the automotive industry.

Plastic in sensors and infotainment systems

On average, plastics make up less than 10% of a vehicle's weight but account for approximately 50% of its volume. Plastics are increasingly being used in vehicles, including electric vehicles like Teslas, to improve fuel efficiency and reduce costs and carbon emissions.

Tesla's Autopilot system, an advanced driver-assistance system, uses a variety of sensors and an onboard computer. Over the years, Tesla has made several hardware changes to its Autopilot system, including the use of cameras, radar sensors, ultrasonic proximity sensors, and custom computer chips. The latest version, Hardware 4, includes eight cameras, 12 ultrasonic sensors, and forward-facing radar. These sensors and computers enable features such as auto lane change, Autopark, and side-collision warning.

While the specific amount of plastic used in these sensors and infotainment systems is not publicly available, it is safe to assume that plastic is a significant component. Plastic is commonly used in the production of sensors and electronic devices due to its lightweight, durable, and insulating properties.

Additionally, Tesla's infotainment system, found in the Model 3, is controlled through a large display. The display shows pertinent information such as speed, drive mode, warnings, and indicators. The system is software-driven, allowing Tesla to easily add or change functions. This software-driven approach also enables features such as Summon, which allows drivers to remotely control their car to park or back out of tight spaces.

Overall, while the exact amount of plastic in Tesla's sensors and infotainment systems is unknown, plastic is likely a prevalent material due to its advantageous properties in the automotive industry.
