2021 Prius Prime vs. Crosstrek PHEV Comparison

As the "green wave" continues to grow, car manufacturers are looking to make their vehicle lineups more eco-sensitive. Following in the footsteps of the first-mass produced hybrid, the Toyota Prius, the Prius Prime plug-in takes fuel-efficiency to the next level in 2021. Although Subaru is relatively new to offering hybrid engines, they're keeping up with the market by continuing the Crosstrek Hybrid PHEV into the 2021 model year.

Even with the addition of a plug-in hybrid powertrain, the Crosstrek Hybrid only has an EPA-estimated 90 MPGe which is surpassed by the 2021 Prius Prime which has an EPA-estimated mileage of 133 MPGe.
