The Toyota Prius is still one of the most popular hybrids on the road today, but sales have been declining. Last month, Toyota sold 16,857 Prius models, down 43.2 percent from the 29,655 it sold in the same month last year. To try and broaden its appeal Toyota has announced the 2020 Prius Prime, which will be arriving in dealers this summer with some welcome upgrades.

The biggest change is the addition of a newly available rear bench that enables the model to sit up to five people. This replaces the two captain chairs in the previous model that were separated by an armrest and cupholders. Black interior accents also replace previous white accents for a "more premium feel." Other new cabin features include a new sun visor extender and relocated seat heater buttons for front seat passengers for easier usability.

Toyota has also upgraded the Prius Prime's tech. Mercifully, Apple CarPlay is now offered as standard along with Amazon Alexa support and a SiriusXM satellite radio. In addition, Toyota has also renamed the Plus, Premium and Advanced trims levels to the LE, XLE and Limited to match other models in the automaker's lineup.

The 2020 Prius Prime features the same plug-in hybrid powertrain as before, consisting of a 1.8-liter four-cylinder, an electric motor and an 8.8 kWh lithium-ion battery pack. This enables the Prius Prime to produce a combined output of 121 hp. That isn't much power, but the Prius Prime is still extremely efficient with a fuel economy rating of 55 mpg city / 53 mpg highway / 54 mpg combined. It also has an electric range of up to 25 miles.
