We recently had the opportunity to sample the 2019 Prius with Toyota's new AWD-e system, which Toyota says will account for 25% of total Prius sales. This new AWD Prius is able to handle inclement weather while still maintaining a 50-mpg average. Interestingly, when Toyota was explaining potential rivals for the car, its own RAV4 Hybrid was mentioned as the closest competitor.

As with AWD on the Prius, Toyota expects the hybrid model to account for 25% of RAV4 sales. The RAV4 Hybrid manages to achieve just under 40-mpg combined, which is excellent for a crossover. In fact, the RAV4 could pose a serious threat to Prius sales.
