MY2022 data report
What 946 vehicle configurations reveal about fuel consumption, CO2 emissions and smog performance
A clear look at how make, engine size, vehicle class and fuel type are associated with the efficiency and environmental measures reported for new vehicles.
Explore the findings01 / The dataset
Each row represents a vehicle configuration. It does not necessarily represent a completely different model, and the data does not measure vehicle sales.
02 / Fuel efficiency
Three views reveal a broad pattern: fuel use differs across manufacturers and fuel groups, and rises strongly alongside engine size.
Finding 01
Answer
Bugatti records the highest average at 24.80 L/100 km, while Hyundai records the lowest at 7.99 L/100 km.
Interpretation
The gap describes the configurations listed for each make, not a sales-weighted market. Differences may partly reflect the types of vehicles produced by each manufacturer.
Finding 02
Answer
Larger engines are strongly associated with higher combined fuel consumption. The linear trend accounts for approximately 67% of the variation in this dataset.
Interpretation
Configurations with similar engine sizes can still have different fuel-use values. Engine size describes much of the overall pattern, but it does not explain every difference.
Finding 03
Answer
E85 has the highest average fuel consumption. Regular gasoline and diesel are nearly identical in this dataset, differing by only 0.007 L/100 km.
Interpretation
Fuel type alone should not be interpreted as the cause of these differences because vehicle and engine composition also varies across the four groups.
03 / Environmental performance
CO2 emissions and Smog Ratings describe different environmental characteristics. The charts should be read separately.
Finding 04
Highest
Standard pickup trucks
309.4 g/km
Lowest
Small station wagons
192.5 g/km
Interpretation
Two-seaters average 307.3 g/km and standard SUVs average 302.3 g/km. Class is associated with substantial differences, but the class name alone does not explain every result.
04 / Smog ratings
The 100% stacked bars compare the internal distribution of ratings within each vehicle class, making differently sized classes easier to compare.
Finding 05
Official rating scale
approximately have Smog Rating 1
approximately have Smog Rating 6
Interpretation
A higher Smog Rating indicates better performance. Smog Rating is not the same as CO2 emissions; the two measures describe different environmental characteristics.
05 / Key takeaways
Together, the five views show why efficiency and environmental performance need more than a single measure or category.
The distance from 24.80 to 7.99 L/100 km reflects very different mixes of MY2022 configurations.
A strong positive association links larger engines with higher combined fuel consumption.
E85 stands apart, while regular gasoline and diesel are almost identical in this dataset.
Standard pickups rank highest, but two-seaters follow closely despite their different class profile.
Rating distributions vary within classes and should not be used as a substitute for CO2 results.
06 / Read with care
These results are a useful description of one dataset, not a complete account of every vehicle in the market.
