Mechanical Genius
Both the standard Prius hybrid and the Prius Prime are powered by the Toyota Hybrid Synergy Drive powertrain, which seamlessly combines the output of the gasoline engine and electric motor through a planetary-type continuously variable transmission. The biggest difference is that the Prius Prime can be plugged in at home to recharge its larger 8.8kWh battery pack.
In Hybrid mode, the Prius Prime can run on the gasoline engine or electric motor alone or a combination of both. Even when not running in EV mode, the Prius Prime will automatically rely more on its electric capability in situations where it is more efficient than running the gasoline engine, especially in urban and suburban driving and during shorter trips.
The Prius Prime will also feature a Toyota-first dual motor generator drive system, using both the electric motor and the generator for drive force, helping to boost acceleration performance. Regenerative braking recaptures electrical energy under deceleration and braking and stores it in the battery, which helps to reduce fuel consumption.
Even better, there is no special equipment for home charging. Just use the supplied cord and the Prius Prime takes approximately 5.5 hours using a standard household outlet. Charging takes less than half the time with a 240V source.

Efficiency Expert
Not to be overshadowed by all the electrical magic, the Prius Prime gasoline engine also plays a starring role in that efficiency. The 1.8-liter Atkinson-cycle, 4-cylinder engine – the same as in all 2016 Prius hybrid models – earns a groundbreaking 40 percent-plus thermal efficiency. Most modern automobile engines reach about 25-30 percent. Myriad details throughout the hybrid powertrain contribute to the efficiency, including an exhaust gas recirculation (EGR) system with a cooler, smaller, lighter, quieter hybrid system water pump and an exhaust heat recirculation system that speeds engine warm-up.


The Prius Prime coddles the driver and passengers with standard heated front seats, an automatic climate control system, and available SofTex® synthetic leather trimmed seats. The climate control system is quieter, thanks to an electric compressor, and it is smarter, focusing airflow only to areas where occupants are seated in order to help maximize fuel economy and comfort. The climate control system can also operate without the engine on, with a heat pump that allows the system to cool or heat the cabin while driving in EV mode. The driver can activate the remote air conditioning system with an available key fob or smartphone app to cool the interior before entering the cabin.

High Tech, Low Effort
The centrally mounted gauge panel, a Prius hallmark since the model inception, appears to float above the dashboard. The panel features dual 4.2-inch full-color TFT (thin film transistor) multi-information displays, and the driver can change their content by using steering wheel controls.
The display provides a multitude of readouts for hybrid energy information and more, and the driver can choose how much information to view. Want to cut the cord? With available wireless cell phone charging for Qi-compatible devices, just place your Qi-compatible devices on the console pad to charge it wirelessly.

Multimedia Mogul
Sound and vision inside the Prius Prime likewise meet the standard of “prime.” Toyota equipped this top Prius with its top Entune® multimedia system and made it all accessible through a new and exclusive 11.6-inch HD tablet display. The navigation graphics look simply stunning, and intuitive touch controls make operation a snap.
Prius Prime will also offer an exclusive suite of Prius Prime Apps, allowing you to remotely manage the charging schedule and status, locate charging stations, track and compare your eco driving score with others on social media, remotely control the climate system, and more – all from your smartphone.
An available Entune™ Premium JBL® Audio system with Integrated Navigation and App Suite puts 10 JBL GreenEdge™ speakers in six locations for sonic bliss. The Entune™ Multimedia Bundle includes AM/FM cache radio (letting you pause songs and play later), HD Radio™, HD Radio™ predictive traffic and Doppler weather overlay, SiriusXM® Satellite Radio with 3-month complimentary SiriusXM All Access trial and Gracenote® album cover art.
Of course, there is a USB 2.0 port with iPod® connectivity and control, plus advanced voice recognition and hands-free phone capability, phonebook access and music streaming via Bluetooth®. For iPhone users, Siri® Eyes Free mode adds yet another in-car assistant.
The Entune™ App Suite adds yet more music sources, including Slacker Radio, iHeartRadio and Pandora® as well as Destination Search, MovieTickets.com, OpenTable®, Facebook Places, Yelp™ plus real-time traffic, weather, fuel prices, sports and stocks. Access to Entune® services is subscription-free.
The 2017 Prius Prime will begin arriving in Toyota showrooms in late fall.
