Driving Change: How Today’s Cars Are Built for a Greener Tomorrow
Today’s automakers create more efficient and sustainable products to reduce their carbon footprints. While vehicles are more eco-friendly, the manufacturing processes have also become environmentally conscious.
Here are 10 ways modern cars are part of building a greener tomorrow.
1. Electrification
The rise of electric vehicles (EVs) has been integral to reducing environmental impact and making cars greener. Since Toyota unveiled the Prius in 1997, the market has only expanded for eco-conscious vehicle designs. Some feared EV sales would dip in 2024, but they increased from 2023 and met the forecasted numbers.
EVs eliminate the need for gas because of their strong motors. The absence of fossil fuels means you don’t have dangerous emissions from the tailpipe. Electric cars are a modern symbol of eco-friendliness, and they’re steadily improving. Automakers are developing solid-state batteries and hydrogen fuel-cell vehicles to make your journeys even greener.
2. Improved Aerodynamics
While EVs are the next big thing, automotive experts are bringing sustainable changes to all cars. Modern vehicles are becoming more aerodynamically sound, making them more efficient and easier to handle. With less drag, you optimize the airflow and decrease wind resistance on the open road.
Improving aerodynamics has made maximum fuel economy easier to implement. For example, automakers use smoother underbody panels to reduce turbulence and drag. These plates are large enough to cover exposed undercarriage components, thus shielding them from wind resistance. Other critical innovations include streamlined bodies, adjustable spoilers and active air skirts.
3. Sustainable Interior Fabrics
When you sit in a cozy leather seat, you might not realize its environmental impact. Auto manufacturers are shifting away from leather because of the required production energy. Instead, they’re leaning on cruelty-free products and sustainable materials to make your ride comfortable.
Vegan leather has become more prominent for automakers because it feels similar to the real thing. BMW recently launched a vegan leather for its 5 Series, making it the default interior fabric option.
4. Lighter Composition
If a car is lighter, it uses less fuel to propel itself forward. Automakers have ditched heavy materials to reduce weight and make their products more efficient. Industry leaders have been working toward this goal since the 1970s when they started choosing aluminum over conventional steel.
While modern vehicles contain lightweight materials, they’re safer than steel jalopies from the past. Auto manufacturers are using carbon fiber because it’s lighter and stronger than steel and can be cheaper to produce. You’ll primarily find it in luxury cars, though this material is gradually entering the mainstream market.
5. Recycling Mindset
Sustainable disposal is essential once your car reaches the end of its life. Automakers reduce their ecological impact by using recyclable materials to minimize the environmental footprint and make the vehicle’s final stages more manageable.
Modern manufacturers have implemented closed-loop recycling systems, which reuse materials in their last stages. Thanks to these practices, workers can turn scrap into sheet metal for the newest models. Automakers recycle materials like steel and aluminum, though the options are expanding to include ocean plastics and single-use water bottles.
6. 3D Printing
3D printers have become popular in construction, health care and space exploration. They’re making life easier for automotive companies by reducing waste and making production more efficient. For example, additive manufacturing simplifies part design by creating internal lattices and hollow structures and reducing weight.
Automakers leverage 3D printers for on-site part production, thus removing the need for extra transportation and emissions. The environmental benefits spread to the recycled materials used in additive manufacturing, such as soy, cornstarch and hemp. You can also see 3D-printed parts of your car, such as brake and engine components. In 2021, Porsche introduced bucket seats using this futuristic process.
7. Renewable Plant Power
Automakers aren’t just making their cars more sustainable — the efficiency has spread to their plant production. These gigantic facilities require immense energy, so alternative sources are necessary to reduce greenhouse gas emissions. By harnessing natural resources, companies are on their way to meeting carbon neutrality goals.
General Motors has set a 2035 target of using 100% renewable energy globally. Whether at Chevrolet or Cadillac plants, facilities will reduce intensity levels and generate clean power. Ford has implemented similar policies at its production plants worldwide with solar canopy carparks. These parking lots protect finished vehicles while providing power for assembly.
8. Solar Integration
Solar is slowly integrating itself into the automotive industry through automotive plants, and the story doesn’t stop in the production facility. Newer cars are leveraging solar power to supplement electric power and increase their range. For instance, the 2024 Toyota Prius Prime offers photovoltaic panels on the roof to help the battery charge.
The general public has yet to access a car solely relying on solar power, though experts have attempted such models. For example, the Lightyear 0 is an EV that harnesses the sun’s power while on the go and reduces daily charging needs. Lightyear limited its production due to financial troubles, but it showed that a solar-powered car is possible.
9. Water Consumption
Producing the average car requires more water than you might think. From the boiler feed to the paint, a vehicle consumes a lot of water in production. Some automotive plants are in drought-prone areas, so conservation efforts are necessary. Luckily, manufacturers have started to figure out water-saving tactics.
Automakers have lessened their reliance on municipal supplies by harvesting rainwater. Ford plants worldwide have harnessed this natural resource for irrigation and pallet washing while reducing discharge. Closed-loop systems are also useful for water, letting facilities recycle and reuse it in manufacturing. Reducing power and water consumption together helps the planet.
10. Autonomous Features
Self-driving cars are a major goal of the automotive future, and manufacturers have already implemented autonomous features that increase sustainability. Adaptive cruise control and self-parking components might seem small, but they go a long way in making your automobile better for the environment.
Autonomous vehicles make driving easier by accelerating and decelerating for you. When you smartly speed up and slow down, you conserve fuel and help the engine work less. As self-driving cars become more connected, they’ll likely optimize traffic flow and reduce the burden of bumper-to-bumper rush hours. Instead, you’ll get real-time updates on the best routes.
Building Cars With Green Thumbs
The automotive industry has been responsible for a large part of fossil fuel emissions, so it must turn the tide with eco-conscious processes. Increasing sustainability starts in the factory and includes renewable energy and water conservation. From vegan leather to electric motors, modern cars can boast environmental friendliness and reduce their carbon footprints.
