Powered by a larger and more powerful 100 kW 1.8-liter Atkinson-cycle, four-cylinder engine, the third generation Toyota Prius is the most fuel efficient yet and consumes just 50 MPG (US EPA test schedule). This is achieved via a combination of innovative technologies including the aforementioned solar panel and new engine plus a coefficient of drag (Cd) value of just 0.25.
Built on an all-new platform, the third generation Prius boasts improved handling stability, quieter operation, and collision safety. The suspension consists of front struts and a rear intermediate beam design, as before, but handling stability is advanced by improving the stabiliser layout, higher caster angle and tuning the bushing characteristics. Disc brakes are now used on all four corners, replacing the front disc/rear drum brakes in the current model.
Better-performing sound insulation, working with improved vibration damping, has been installed in various locations to reduce road noise.
The new Prius features a futuristic cabin with improved cargo space, a smooth-flowing centre stack and touch sensors on the steering wheel switches which have been designed to reduce driver eye movement for better concentration on the road. When the driver touches the audio or info switch located on the steering wheel, a duplicate image is displayed on the instrument panel, directly in front of the driver. This system, called Touch Tracer, is the first system in the world to allow steering wheel controls to read out on the instrument panel.
