What Goes Into CR's Overall Score for Cars
The score factors in road-test performance, reliability, owner satisfaction, and safety
No single attribute makes a car truly great by itself. That’s why Consumer Reports has always rated each car using a group of assessments, either data-driven or drawn from the experiences of our testers and members.
Overall Score Factors
Every car we test gets a score that encapsulates four key factors: road test, reliability, owner satisfaction, and safety.
1. Our road-test program looks at how vehicles perform in the real world. We run roughly 50 new cars and trucks each year through more than 50 tests at our 327-acre test facility in Colchester, Conn. Those tests include acceleration, braking, emergency handling, and fuel economy, among others. We also evaluate usability, fit and finish, noise, ride, and safety systems. For electric vehicles, we consider factors such as speed and ease of charging, and range.
2. We survey Consumer Reports members to predict the reliability for new cars. Every year, we collect detailed information on their experiences with hundreds of thousands of cars. The data is presented online from among 20 key trouble areas.
3. Owner satisfaction is based on whether a CR member would definitely get the same car if they had a chance to do it over again, effectively measuring whether a car lived up to its owner’s expectations. In our exclusive Auto Survey, owners also rate their cars for the driving experience, comfort, and value.
4. Safety ratings include crash-test data from the Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA), if they’ve been conducted. We give extra credit to vehicles that have the advanced safety systems that have been shown to reduce crashes, injuries, and deaths when they are offered as standard equipment across all trim levels of a model. And we deduct points from monostable gear selectors that lack fail-safes (such as automatically returning to Park or engaging the parking brake when the engine is shut off or the driver’s door is opened) to prevent the possibility of rollaway crashes. We also consider whether the model has a driving automation system with an effective driver monitoring system.

The Overall Score is not static. As new testing, reliability, owner satisfaction, and safety data become available, the scores will be updated on CR.org. That means members can always access the most current assessment of what makes the best-driving, most reliable, most satisfying, and safest cars.
