2023 Toyota Prius w/ the 1.8L I4 <-- Not offered here. Yet. 
Combined Mode: 32.6 km/L - 13.9% higher than the 2.0L
City Mode: 29.9 km/L - 15% higher than the 2.0L
Suburban Mode: 37.3 km/L - 20.0% higher than the 2.0L
Highway Mode: 31.2 km/L - 10.6% higher than the 2.0L
That’s about 73 miles per gallon on the highway with the 1.8L version! Insane |
Japan also overestimates the fuel economy of most cars versus the EPA test since speeds are usually lower in Japan than the US.
The combined 28.6 km/l for the 2.0L is about 67 mpg US. I would be surprised if the real world numbers in the US were higher than around 54 mpg. 32.6 for the 1.8L / 28.6 for the 2.0L with 54 mpg US shows that the 1.8L gets about 13% better fuel economy than the 2.0L. If the 2.0L has 54 MPG real world average in the US, that's still 61 mpg for the 1.8L which is pretty impressive. We'll have to keep an eye out on Fuelly to see what the actual real world numbers are though.
