First of all, a HUGE thank you to Toyota of Long Beach20 minutes ago
New "official" size designations in the U.S. were introduced by the EPA, which defined market segments by passenger and cargo space. Formerly mid-sized cars that were built on the same platform, like the AMC Matador sedan, had a combined passenger and cargo volume of 130 cubic feet (3.68 m3), and were now considered "full-size" automobiles.
The Prius offers Toyota's in-house Entune software for smartphone integration. Setup requires a lengthy app download and account creation process. Entune's app support is meager and less intuitive than CarPlay or Android Auto (neither of which is offered). The Bluetooth menu offers better control and search functionality than most other Bluetooth systems.
