The 2019 Toyota Prius is part of the model's fourth generation. It is powered by a 1.8L four-cylinder engine combined with electric motors to produce 121 horsepower. The vehicle employs a continuously variable automatic transmission (CVT) and comes standard in front-wheel drive, with an all-wheel drive option introduced for this model year. There are four available trims: L Eco, LE, XLE, and Limited. Key safety features include forward collision warning with automatic emergency braking, lane departure warning and intervention, and adaptive cruise control, thanks to the Toyota Safety Sense P suite of active safety features. The infotainment system sports a 6.1-inch touchscreen, though a larger 11.6-inch display is available on upper trims. It supports Apple CarPlay and Amazon Alexa. Notably, the 2019 model introduced the new AWD-e system, extending the Prius' appeal to buyers in harsh weather climates.
