Product Reviews

Welcome to Consumer Reports.

We’re so glad to have you as a member. You now have access to benefits that can help you choose right, be safe and stay informed.
Many people simply need a car to get efficiently and reliably from A to B, with little cost or fuss. For that, it's hard to beat the Toyota Prius, as it meets the basic transportation needs of just about everyone. At 44 mpg overall in our tests, only electric cars were more fuel efficient. Despite the apparent complication of the hybrid system, all of the Prius' technology is well-proven.

Road Test Results

Performance
Acceleration Acceleration Acceleration tests are conducted on a smooth, flat pavement straightaway at the track. Time, speed, and distance measurements are taken with a precise GPS-based device that’s hooked to a data-logging computer.
0 to 60 mph (sec.) 0 to 60 mph (sec.) The time in seconds that a vehicle takes to reach 60 mph from a standstill with the engine idling.
Transmission Transmission Transmission performance is determined by shifting smoothness, response, shifter action, and clutch actuation for manual transmissions.
Fuel Economy Fuel Economy We perform our own fuel-economy tests, independent of the government's often-quoted EPA figures and the manufacturers' claims. Using a precise fuel-flow measuring device spliced into the fuel line, we run two separate circuits to represent city and highway consumption.
CR's Overall Mileage CR's Overall Mileage CR's overall mileage is a composite of measured fuel usage on a prescribed city course and highway cruising; and CR's 150-mile test trip of mixed driving, if tested. In recent road tests, we've discontinued the 150-mile trip test.
CR's City Mileage CR's City Mileage Measured fuel usage on a prescribed city course.
CR's Highway Mileage CR's Highway Mileage Measured fuel usage on a prescribed highway cruising.
Annual Fuel Cost Annual Fuel Cost The cost and amount of fuel used in 12,000 miles and is calculated from CR's overall mileage.
Braking Braking The braking rating is a composite of wet and dry stopping distances and pedal feel. Braking distance is from 60 mph, with no wheels locked.
Emergency Handling Emergency Handling Several factors go into the rating, including the avoidance maneuver speed and confidence, as well as how the vehicle behaves when pushed to its limit,
Comfort / Convenience
Ride Ride Our expert judgment of how well the suspension isolates and absorbs road imperfections and how steady it keeps the body on various road surfaces.
Noise Noise Our expert judgment of the vehicle's interior noise level in everyday driving.
Front Seat Comfort Front Seat Comfort Our judgment of how comfortable the front seat is for drivers of various heights.
Rear Seat Comfort Rear Seat Comfort Our judgment of how comfortable the rear seat is for two passengers to sit across.
Interior Fit and Finish Interior Fit and Finish An expert evaluation of the interior quality and craftsmanship.
Trunk/Cargo Area Trunk/Cargo Area Our rating is based on the amount of luggage or cargo space that a vehicle has in the trunk or cargo area.

Owner Reports

Worse Better
Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Road Test

Many people simply need a car to get efficiently and reliably from A to B, with little cost or fuss. For that, it's hard to beat the Toyota Prius, as it meets the basic transportation needs of just about everyone. At 44 mpg overall in our tests, only electric cars were more fuel efficient. Despite the apparent complication of the hybrid system, all of the Prius' technology is well-proven. The Toyota Prius has one of the lowest costs of ownership.

The hatchback body is aerodynamic and spacious for both people and cargo. Rear-seat space is on par with many midsized sedans, with plenty of cargo capacity to boot. Folding down the rear seats makes even more room.
