The most efficient cars for 2022


This story is part of The cost of climate change, CNET’s coverage of the impact of climate change on a range of financial issues.

Besides being one of the most expensive purchases you can make, a car is the one that will affect a household’s carbon footprint the most. It’s not just the cost of the car itself. The cost of fuel and greenhouse gases emitted over the life of the vehicle must also be taken into account.

We have compiled this list of the most efficient cars, with input from our colleagues on the Roadshow team. We looked at the energy efficiency ratings released by the Environmental Protection Agency and used its efficiency conversion formula to see how electric vehicles stack up against their gasoline alternatives.

It should be noted up front that smaller cars are generally more efficient than larger ones, but we have included the trucks and SUVs that are the most fuel efficient in their class. And while hybrids and EVs tend to have higher sticker prices, financial motivations available at the federal and state level can make them considerably more affordable. And that’s before the fuel costs drop.

The cars listed here are arranged in descending order of overall efficiency, with the top tier populated by electric vehicles. After that, we have plug-in hybrids, which can run on fuel or electricity. And then pure hybrids, which require both fuel and electricity.
