Toyota Prius XW50: The Fourth Generation From Leak to Successor
The fourth-generation Toyota Prius, code XW50, was revealed in Las Vegas in September 2015 and reached Japanese showrooms on 9 December 2015. It was the first Toyota on the TNGA platform, and a plug-in version came in 2016. Production ran until 2022, when the fifth-generation XW60 took over.

Key takeaways
- Drawings leaked in mid-2015; the official reveal came in Las Vegas in September 2015.
- First car on Toyota New Global Architecture (TNGA GA-C), with a drag coefficient of 0.24.
- 1.8-litre hybrid with a system output of 90 kW (122 PS); EPA rating of 4.5 l/100 km.
- Replaced by the XW60 in 2022–2023, sold in Europe only as a plug-in hybrid.

What the 2015 leak showed
In July 2015 drawings of the new Prius appeared online, credited by the old 1cars report to a Taiwanese magazine. They showed a standard hybrid and a plug-in version with a different front end.

The car did grow longer and lower, and a plug-in did follow, but the figures were less accurate. The leak spoke of a combined output of about 110 kW (150 hp) and a 50 km electric range. The real hybrid had a lower combined output, and the plug-in came later than the hatchback.

TNGA and the new hybrid
The XW50 was the first model on TNGA, the platform that later carried the C-HR and the twelfth-generation Corolla. A lower centre of gravity and double-wishbone rear suspension made it, in most reviews, better to drive than the old car.
The AWD-e version, offered in Japan from launch and in the USA from the 2019 model year, added a 5 kW motor at the rear axle.
The Prius Plug-in that followed
The plug-in version was revealed at the New York show in March 2016. It was sold as the Prius Prime in North America and the Prius Plug-in Hybrid in Europe. It had an 8.8 kWh battery and could drive on electricity at up to about 130 km/h.
North American testing gave about 35 km of electric range, double the previous plug-in Prius.

Which Prius to buy used: our view
A 2016–2022 XW50 is the sensible used buy for drivers who cover city and suburban miles. Choose the facelifted 2019 car if you dislike the original headlights. The plug-in suits buyers who can charge at home every night; otherwise its extra weight brings no gain.
Its main rival from 2016 was the Hyundai Ioniq. Compare the two with the comparison tool or browse every model in the Toyota catalogue.
