What is the CO2 emissions of the Yaris hybrid?

The Yaris Hybrid generally emits about 85–95 g/km of CO2 under European WLTP testing, with variations by trim, tyres, and driving conditions. In other regions, numbers differ and some markets don’t offer the model at all. This article outlines the typical figures, what drives them, and how to find the exact rating for your car.

Understanding the CO2 figure requires noting that emissions are cycle- and market-specific. The Yaris Hybrid uses a 1.5-liter Atkinson-cycle petrol engine paired with an electric motor, and the final number depends on wheel size, tires, drivetrain (if any), and local testing standards.

How CO2 ratings are measured for the Yaris Hybrid

These lists summarize typical values by testing cycle and market, and explain what can cause small differences between versions.

• Typical WLTP CO2 range for the European Yaris Hybrid: about 86–92 g/km, depending on wheel size and equipment.


• Impact of tyres and wheels: larger wheels or certain tire types can push the figure toward the higher end of the range.


• Cycles and cycles' differences: older NEDC values (where shown) are higher than WLTP values; always check the WLTP figure for current models.

In practice, the official WLTP figure shown on European spec sheets is the one used for tax and labeling in most markets, and it reflects recent improvements in hybrid efficiency compared with earlier cycles.

Regional snapshots

The availability and the official CO2 ratings for the Yaris Hybrid vary by market and year. Here is a region-by-region orientation with caveats about cycles and specifications.

Europe and the WLTP standard

Europe uses the WLTP cycle for CO2 labeling, and Yaris Hybrid figures typically land in the mid-80s to low-90s g/km range depending on trim and tyres.

• Range: approximately 86–92 g/km (WLTP) for common European specifications.


• Notes: tyres, wheel sizes, and optional equipment can shift the exact value within this range.

Practical takeaway: if you’re comparing models or reading a tax boilerplate, use the WLTP figure for an apples-to-apples comparison in Europe.

Other markets

Several regions publish their own cycles or have different model availability. The Yaris Hybrid is not always offered in every market, and the official CO2 figure may come from a local WLTP-equivalent or a different labeling standard.

• United States and Canada: current Yaris lineup in these markets does not include a dedicated Yaris Hybrid; closest options are other Toyota hybrids (e.g., Corolla Hybrid, Prius) with separate CO2 ratings under EPA/NEDC-style labs.


• Japan and Australasia: local ratings typically use a WLTC-equivalent standard, with CO2 figures broadly in the same ballpark as Europe, adjusted for local tires and trim.

For an exact number in a given market and for a specific model year, consult the official regional vehicle brochure or the dealer’s specification sheet.

How to find the exact CO2 figure for your car

Since the CO2 value depends on the precise configuration, here are practical steps to verify the rating for your Yaris Hybrid:

• Check the official Toyota regional website for your market and model year to locate the CO2/km figure listed for the Yaris Hybrid.


• Look up the car’s brochure or price list, which typically includes the WLTP (or local cycle) CO2 emissions by trim.


• Review the vehicle’s window sticker or Monroney label when shopping in regions that require it; this displays the exact CO2 rating for that configuration.


• Ask a dealer for the precise CO2 figure for your specific trim, wheel size, and tire choice, since small changes can shift the value by a few g/km.

Having the exact figure helps you compare efficiency with other vehicles and estimate running costs or tax obligations in your country.

Summary

The Yaris Hybrid’s CO2 emissions are typically in the mid-80s to low-90s g/km range under WLTP in Europe, with regional differences based on testing cycles and market availability. Always refer to the official regional specification for the precise value of your particular configuration, and remember that tyres, wheel size, and trim can cause small variations.

Is a Toyota Yaris a low emission car?

Toyota Yaris
It'll come as no real surprise that there's a second Toyota in our low emissions line-up. They really are some of the best around if you're looking at lowering your emissions, and the Toyota Yaris is an absolute classic.

How many miles per gallon does a Toyota Yaris Hybrid get?

The Toyota Yaris Hybrid's MPG varies by model year and driving conditions, but it is generally very high. In real-world driving, figures often exceed 60 MPG, and some owners report achieving 70 MPG or more, especially in city driving. The 2025 models are officially rated between 57.6 and 70.6 MPG, with real-world city figures reaching over 70 MPG and combined figures often around 60 MPG. 
Real-world fuel economy

• City: You can realistically expect 60 MPG, with some reports reaching 70 MPG or even 80 MPG with careful driving. 
• Combined: Real-world combined figures are often in the 60s MPG. 
• Highway: MPG will drop at higher speeds, but 50 MPG is still a realistic figure.

Official ratings (2025 model)

• Official consumption: Varies between 57.6 and 70.6 MPG, depending on the specific configuration.
• CO2 emissions: Are between 91g/km and 97g/km, depending on the configuration. 

Factors affecting MPG

• Driving style: Gentle acceleration and driving at lower speeds, especially in the city, significantly improve fuel economy.
• Driving conditions: Highway and higher-speed driving will result in lower MPG.
• Model year: Different model years will have different official and real-world figures. 

What are the disadvantages of the Toyota Yaris Hybrid?

What are the disadvantages of the Toyota Yaris? The Yaris is a very good all-round car, but there are some issues. The cabin looks cheap, the back seat is really quite cramped, and the boot is smaller than you get in most of the competition.
