Frequently Asked Questions
Do I need gas in the tank?
You should never drive Prius Prime without gasoline in the tank. While, under certain conditions, you may drive on electricity alone, the vehicle always requires gasoline to operate properly.
Do I need to plug in Prius Prime to use it?
No, but it is generally advantageous to keep it charged. Depending on your electricity rate, you could save money by plugging it in. The more often you keep Prius Prime fully charged (at home, work or anywhere with a public charging station), the greater your gasoline fuel savings will be.
How does it work?
Prius Prime uses a series parallel hybrid system, which means it can drive the wheels using both electric motors and/or its gas engine. If the battery is fully charged, Prius Prime runs on the electric motors only. When the battery runs out, it operates like Prius, using both the gas engine and electric motors to drive the car as they are needed and available. See how the system works here.
How long does it take to charge?
Prius Prime’s battery can be charged in less than 5 hours and 30 minutes by plugging the included charging cable into a standard household outlet. [prime_120v] [prime_gfci] When using a public charging station (240V), Prius Prime can be fully charged in approximately 2 hours and 10 minutes.
How long is Prius Prime’s battery designed to last?
The battery in Prius Prime is designed to last for the life of the vehicle.
What is a plug-in hybrid?
A plug-in hybrid vehicle (PHV) is similar to Prius, but with a larger battery and more powerful motors that allow it to run much longer in full EV Mode. [prime_hybrid_caution] You are in control and able to use less gas if you choose to plug it in either at home, at work or at a public charging station. If you don’t want to plug it in, no problem, you can still drive the car in hybrid mode with great fuel economy.
What separates Prius Prime from other Prius models?
Prius Prime works similarly to a standard Prius, but with an increased EV Mode [prime_hybrid_caution] driving range, more powerful electric motors and enhanced fuel efficiency. It continues to set itself apart with a completely unique front and rear design. The advanced Quad-LED projector headlights, LED taillights and signals help light the night in a most dramatic and efficient fashion. The aerodynamically formed rear glass and hatch represents another leap forward. The carbon-fiber-reinforced-polymer construction is a Toyota first and results in a lightweight, easy-to-lift hatch.
What is the expected driving range?
Prius Prime has an impressive EPA-estimated total driving range of 640 miles [prime_2017_range_rating] and an EPA-estimated EV Mode [prime_hybrid_caution] range of 25 miles [prime_2017_ev_range] if only recharging once. If Prius Prime is kept fully charged, it allows the driver the ability to save and potentially use less gasoline, yet still have the total driving range and efficiency expected from a Prius.
