For 2020, Toyota is giving the Prius Prime an extremely modest update, highlighted by the addition of a fifth seat – the previous version only had belts for four occupants. Toyota also switched up the naming architecture of the trim levels to better align with the branding of other cars such as the Corolla and Camry. The mild changes are reflected by slight increases in starting prices.
The Prius Prime's main draw, its 54 mpg combined fuel numbers and 25 miles or estimated electric range, remain exactly the same for the 2020 model year, but Toyota made slight alterations to update the model. Most notably, the rear seat has been changed from a two-seat configuration to accommodate a third middle seat. The old model features an arm rest and cup holders between two seats.
