The Prius was successful due to its technological advances, lower price than other hybrids and SUVs, and its ability to appeal to consumers affected by high gas prices. Toyota's launch of the Prius took advantage of society's need for more fuel efficient vehicles when gas prices were rising and people drove uneconomical vehicles. Government incentives further contributed to the Prius' popularity by offering tax breaks for hybrid owners. Competition in the electric vehicle market was growing as most major automakers began introducing electric models across various vehicle classes between 2009-2012.
