electric, but supplemented by the internal combustion engine). Toyota ultimately only did a small production run with 75,400 vehicles being produced between 2012 and 2016. The second-generation Prius Plug-in (renamed the Prius Prime in the US) was unveiled in early 2016. Unlike the prior generation, where the plug-in battery was limited by being added to the existing Prius, this model would be developed in tandem with the fourth-generation Prius, allowing Toyota to increase the range to , with a top speed of , without needing the assistance of the internal combustion engine. The second-generation Prius Plug-in went on sale starting in late 2016, with Toyota expecting to sell up to 60,000 units globally per year. A second plug-in hybrid model, the Toyota RAV4 PHV (RAV4 Prime in the US) was unveiled in December 2019. The vehicle has an EPA-estimated of all-electric range and generates a combined , enabling it to be Toyota's second fastest car currently in production (behind the GR Supra 3.0 sports car). Sales started in mid-2020. Battery electric vehicles Toyota has been criticized for being slow to add battery electric vehicles to its lineup. It was publicly skeptical about battery-electric technology, and has lobbied against government mandates to transition to zero tailpipe emission vehicles. Toyota's first all-electric vehicle was made in response to one of those government mandates. The company created the first generation Toyota RAV4 EV after the California Air Resources Board mandated in the late 1990s that every automaker offer a zero-emissions vehicle. A total of 1,484 were leased and/or sold in California from 1997 to 2003, when the state dropped its mandate under legal pressure from lawsuits filed by automakers. At the lessees' request, many units were sold after the vehicle was discontinued. A second generation of the RAV4 EV was developed in 2010 as part of a deal with Tesla. The production version was unveiled in August 2012, using battery pack, electronics and powertrain components from the Tesla Model S. The RAV4 EV had a limited production run which resulted in just under 3,000 vehicles being produced, before it was discontinued in 2014. According to Bloomberg News, the partnership between Tesla and Toyota was "marred by clashes between engineers". Starting in 2009, Toyota introduced three generations of concept electric vehicles called the FT-EV built on a modified Toyota iQ platform. In late-2012, the company announced plans build a production version of the car
