Does PZEV affect gas mileage?
Yes, PZEV (Partial Zero Emission Vehicle) can affect gas mileage, but the impact is typically small. PZEV is a designation for vehicles that meet strict emissions standards, and the technology used to achieve these standards can have a slight effect on fuel efficiency.
What is PZEV?
PZEV is a California emissions standard that requires vehicles to have near-zero evaporative emissions and extremely low tailpipe emissions. Automakers achieve this by using advanced emission control technologies, such as catalytic converters, evaporative emission control systems, and other components. These technologies help reduce the vehicle's overall environmental impact, but they can also have a small impact on gas mileage.
How Does PZEV Affect Gas Mileage?
The main ways PZEV technology can affect gas mileage include:
- Increased Vehicle Weight: The additional emission control components required for PZEV add some extra weight to the vehicle, which can slightly reduce fuel efficiency.
- Increased Drivetrain Friction: Some PZEV technologies, like the catalytic converter, can increase drivetrain friction, leading to a small decrease in gas mileage.
- Reduced Engine Efficiency: Certain PZEV modifications, such as changes to the engine or fuel system, can marginally reduce the engine's overall efficiency, resulting in slightly lower gas mileage.
However, the impact of these factors is typically quite small, often less than 1-2% reduction in fuel efficiency. Many automakers are able to offset these minor losses through other design improvements to maintain or even improve the overall gas mileage of PZEV vehicles.
Conclusion
In summary, while PZEV technology can have a slight impact on gas mileage due to the additional components and modifications required, the effect is generally quite small and often negligible compared to other factors that influence a vehicle's fuel efficiency. Automakers work to minimize any negative impacts of PZEV so that drivers can enjoy the environmental benefits without significant sacrifices in fuel economy.
What are the pros and cons of PZEV?
Although these features can reduce smog and contribute to cleaner air, PZEVs have some drawbacks. They don't decrease carbon dioxide emissions or improve fuel efficiency. That's why CARB considers them to be a temporary solution for automakers striving to develop viable zero-emissions vehicles.
What is the MPG on a 2015 Subaru Forester PZEV?

What does PZEV mean on Subarus?
What's a PZEV? The Subaru PZEV (Partial Zero Emission Vehicle) is the affordable, no-compromise, eco-friendly alternative.
Is Subaru PZEV good?
A PZEV is classified as the cleanest-running gasoline-powered car on the market and was developed to meet the air quality standards of California, the most stringent in North America. A PZEV must meet the Super Ultra Low Emissions Vehicle (SULEV) tailpipe standard and have zero evaporative emissions.
How many miles per gallon does a Subaru PZEV get?
The Subaru Forester PZEV provides a roomy interior, plenty of technological features, and is a good off-roader. Its fuel economy is 29 mpg combined.
Why do hybrids get better mpg?
Hybrids use two power sources. By sharing the load with an electric motor, the engine in a hybrid car uses less fuel to run than a traditional car. This means a full tank will go further, lowering your running costs. For example, the Honda HR-V hybrid can travel up to 459 miles on its 40L full tank*.
Is PZEV a Subaru hybrid?
While Subaru PZEV models run on regular unleaded gasoline, they offer clear environmental benefits in reducing smog without compromising fuel economy. Their dynamic performance is also equivalent to that of non-PZEV cars and SUVs, whether hybrid, diesel or alternative fuel models.
How do I increase the MPG on my Subaru?
Consider the following strategies:
- Accelerate gently.
- Maintain steady speeds.
- Plan your routes.
- Check tire pressure regularly.
- Using the manufacturer-recommended grade of motor oil improves engine efficiency and offers better ways to improve gas mileage.
- Follow the recommended service schedule for your Subaru.
Is PZEV better than Hybrid?
Is a PZEV better than a hybrid? It depends on what you mean by "better," but the answer is probably no. There are PZEVs that produce less smog-creating pollutants than a similar hybrid, but they usually still emit more greenhouse gases.
What are four ways that Subaru is improving fuel economy?
Subaru is improving fuel economy through enhanced hybrid engine use, better drivetrain efficiency, Electric Power Assisted Steering (EPAS), and active grille shutters. These technologies aim to increase overall energy efficiency in their vehicles.
