The new warranty sees a 24% increase in the years to 10 years and a 50% increase in miles to 150,000.
The coverage will include the company's hybrid, plug-in hybrid, and fuel cell electric vehicles.
The latest RAV4 already comes as a hybrid.
According to the Japanese carmaker, all the 2020 models will offer an upgraded battery warranty of 8 years/150,000 miles from the standard 8 years/100,000 miles. Toyota, however, has clarified that the new warranty will exclude all the other components of the Toyota hybrid line.
So, whether a plug-in hybrid is the way to go or not, there's a RAV4 plug-in hybrid on the way, heading for a Los Angeles Motor Show debut and going on sale in the United Kingdom in 2020.
But a new RAV4 arrived past year, and it offers a much more contemporary take on the RAV4, but cleverly manages to inherit enough of the old RAV4's DNA to not turn off those conservative buyers Toyota has served for so long.
Following the launch of the 2020 RAV4 and RAV4 Hybrid models, Toyota is adding a third variant to the lineup with the announcement of the 2020 RAV4 Plug-in which will debut at the 2019 LA Auto Show next month.
Beyond when it will make its debut and the fact that it'll be available in a new color, Supersonic Red, Toyota didn't provide a lot of information on the RAV4 plug-in.
A spokesperson for the brand today said "at this stage, we have no plans to introduce the RAV4 plug-in hybrid to Australia". We'll have to wait until November 20 to get more information on the plug-in hybrid SUV.
