Where it stands
The midsize cars rated for 2024 run from 17 to 85 MPG, with a median of 30.5 MPG.
Across every class it is the most efficient of the 5 plug-in hybrid models rated that year.
In its class, just ahead of it is the Audi e-tron GT at 85 MPGe and just behind it is the Kia Forte at 34 MPG.
A plug-in hybrid can run on its battery for a distance and then on fuel. The MPG, fuel cost and CO2 figures on this site are for running on fuel with the battery depleted, so a driver who charges often will use less fuel than shown.
Fuel cost and CO2
The file prices the fuel for its most efficient version at about $1,300 a year, assuming 15,000 miles a year with 55% of them in the city and regular gasoline at $4.47 per gallon. That is $1,175 less than the midsize cars median of $2,475.
It emits 50 g of CO2 per mile from the tailpipe; the midsize cars median is 293.5, a difference of 244 g/mile.
Rated versions
It does better in town than on the road: 53 in the city against 51 on the highway, a gap of 2. 2 versions are rated for 2024. The most efficient, Prius Prime SE: 2.0 L, 4 cyl hybrid, Automatic (variable gear ratios), FWD, gets 52 MPG; the least efficient listed, Prius Prime: 2.0 L, 4 cyl hybrid, Automatic (variable gear ratios), FWD, gets 48 MPG, a gap of 4 MPG. With the file's assumptions that gap is worth about $100 a year in fuel.
