How we rank
- Owner reliability, 45 points. Problems that owners report again and again, from our owner reports. A very frequent problem counts twice. Fewer problems than the other cars on this page earns more points.
- New price, 30 points. The median asking price in US listings (Auto.dev). Cheaper than the others earns more.
- Fuel economy, 25 points. EPA combined rating. Electric cars are compared only with other electric cars, in MPGe.
- No guesses. A car needs enough owner reports and three years on sale to be ranked. A number we don't have earns 0 points and says "No data yet". We never compare NHTSA complaint counts between models, because they grow with the number of cars sold.
