Currently the largest car manufacturer in the world, Toyota is a powerhouse in the world of cars and was an early advocate of hybrid cars. You could say the Toyota Prius has been the car that’s made hybrid cars popular among buyers and since that car’s 1997 launch, Toyota’s hybrid system has been used in a wide range of models – such as the Yaris and Corolla – including cars from its luxury Lexus division. Toyota also has a couple of plug-in hybrid models on sale with the RAV4 SUV and Prius Plug-in. Expect big things from it in future though as Toyota is working hard on revolutionary battery tech.
