Subaru’s Overall Eco-Friendly Approach

Subaru’s environmental commitment begins right at the production level. The company’s manufacturing plants—including the Subaru of Indiana Automotive facility—have achieved zero-landfill status, meaning no waste is sent to landfills during the manufacturing process. This achievement is unique in the U.S. automotive industry and highlights Subaru’s dedication to sustainable manufacturing.

Moreover, the Indiana plant holds the distinction of being the only U.S. automobile production plant certified as a backyard wildlife habitat by the National Wildlife Federation. This certification denotes Subaru’s efforts to integrate natural habitat conservation into its manufacturing environment, which benefits local ecosystems and biodiversity.

In the Sunset Hills and St. Charles, MO, regions, where environmental awareness is growing, Subaru’s eco-conscious manufacturing resonates with drivers who want to support brands that prioritize sustainability. This holistic approach extends beyond production to include vehicle design, fuel economy, emissions reduction, and community outreach.

Understanding What Eco Mode Does in a Subaru

Subaru’s Intelligent Drive (SI-DRIVE) system includes an Intelligent (I) Mode, commonly known as “eco mode,” designed to enhance fuel efficiency by adjusting throttle response and engine output. Unlike traditional sportier modes focused on performance, the eco mode prioritizes smooth acceleration and fuel conservation without sacrificing drivability.

When engaged, Intelligent Mode softens throttle response by gradually opening the throttle, requiring less fuel to accelerate. This mode can increase fuel economy by up to 10% during normal driving conditions, particularly beneficial in stop-and-go traffic situations common in Maryland Heights and Glendale, MO. It reduces emissions by minimizing rapid fuel consumption and lowering engine load.

The system intelligently limits fuel injection rates even when the gas pedal is pressed firmly, preventing excessive fuel usage while still allowing responsive acceleration when necessary. Additionally, Intelligent Mode improves traction control by maximizing wheel grip, which is advantageous during wet or slippery conditions often experienced in Valley Park or Twin Oaks.

Drivers can easily switch between Intelligent, Sport, and Sport Sharp modes depending on driving conditions, enhancing fuel savings during urban commutes or enjoying dynamic performance on rural drives.

Four Key Ways Subaru Improves Fuel Economy

Subaru employs multiple engineering strategies to improve fuel economy across its lineup, including:

• 
  

  Active Grille Shutters: These automatically adjust airflow to the radiator, closing at higher speeds to improve aerodynamics and reduce drag. For drivers in Crestwood or Richmond Heights, this technology translates to better highway fuel efficiency without compromising engine cooling.

  
  
• 
  

  Reduced Vehicle Weight: Subaru incorporates lightweight materials and structural optimizations to lower overall vehicle weight. The benefits are clear for urban drivers in Sappington who seek fuel savings without losing vehicle durability.

  
  
• 
  

  Minimized Tire Rolling Resistance: Subaru selects tire compounds and tread patterns that reduce friction between the tire and road surface, decreasing energy loss and improving mpg ratings. This feature is particularly useful for residents of Fenton or Chesterfield navigating diverse terrain.

  
  
• 
  

  Drivetrain Efficiency Enhancements: Subaru continually refines its horizontally opposed Boxer engine, Lineartronic® Continuously Variable Transmission (CVT), and symmetrical all-wheel-drive system to reduce friction and energy waste. These improvements help vehicles achieve competitive fuel economy figures while maintaining Subaru’s hallmark traction and handling.

  
  

These integrated advances enable Subaru models like the Forester and Outback to deliver excellent fuel economy for their classes, making them popular choices among drivers prioritizing sustainability alongside capability.

Are Subarus Zero Emissions? Insights Into PZEV Technology

While Subarus are not fully zero-emission vehicles, many models feature Partial Zero Emission Vehicle (PZEV) technology, a critical step toward reducing environmental impact. PZEV vehicles comply with strict California Air Resources Board (CARB) standards, which are among the most stringent globally.

Subaru’s PZEV system focuses on eliminating evaporative emissions via sealed fuel systems, advanced catalytic converters containing precious metals like palladium and rhodium, and specialized carbon canisters that capture fuel vapors even after the engine is turned off. The Engine Control Module also optimizes ignition timing during cold starts to accelerate catalytic converter efficiency.

For communities like Lakeshire and Creve Coeur, where air quality is a concern, PZEV-equipped Subarus provide cleaner emissions comparable to many hybrid vehicles but without the complexity and cost of electric drivetrain components. Models like the Subaru Crosstrek, Impreza, Forester, and Outback offer PZEV options with competitive fuel economy, making them practical eco-conscious choices.

What Type of Car is Most Eco-Friendly? Comparing Subarus to Industry Leaders

According to the 2024 GreenerCars rankings by the American Council for an Energy-Efficient Economy (ACEEE), electric vehicles (EVs) dominate the top spots, with models such as the Toyota Prius Prime, Lexus RZ 300e, Nissan Leaf, and Toyota bZ4X leading the greenest vehicles list.

While Subaru currently offers the all-electric Solterra, their PHEV and hybrid options lag behind the highest-scoring EVs in pure emissions and fuel cost savings. However, Subaru’s unique focus on AWD capability combined with fuel efficiency provides a niche for drivers in areas like Webster Groves and Richmond Heights who need eco-friendly vehicles capable of handling varied terrains and weather conditions.

For those prioritizing zero tailpipe emissions and access to charging infrastructure, EVs remain the most eco-friendly choice. Yet, Subaru’s blend of environmental stewardship, performance, and all-weather readiness offers a compelling package for drivers balancing eco-consciousness with practicality.

Subaru’s Energy Efficiency and MPG Ratings

Subaru models consistently deliver strong fuel efficiency ratings, which is particularly valuable for residents in St. Louis and surrounding suburbs. The 2022 Subaru Impreza leads with up to 36 mpg on the highway and 28 mpg in the city, making it a top choice for those seeking economical daily transportation.

The 2021 Crosstrek offers up to 34 mpg highway, combining SUV versatility with efficient fuel use, while models like the Legacy, Forester, Outback, and BRZ also offer mpg ratings exceeding 30 on highways. The efficiency gains come from Subaru’s ongoing engine refinements, lightweight designs, and advanced transmissions.

For drivers in Valley Park or Ladue, this means fewer stops at the pump and more time enjoying the drive. The upcoming Subaru Solterra EV promises to further reduce fuel-related emissions and dependence on fossil fuels for the eco-conscious driver.
