In our tests the Prius returned 52 mpg overall, a significant improvement over the previous generation's 44 mpg. On top of that, the new car also handles more responsively and rides more comfortably. Colorful digital gauges dominate the dashboard with abundant fuel-economy information. The touch-screen infotainment system is fairly straightforward. The sensible Prius has always been about efficiency and low running costs. The car can still drive solely on electric, up to about 25 mph typically, and the engine is now quieter when it kicks in. However, the seats are rather chintzy, tire noise is noticeable, and cabin access is not as easy because of the car's lower stance. A plug-in version, the Prius Prime, is new. For the 2017 model year, forward-collision warning with automatic braking is standard.
