First of all, a HUGE thank you to Toyota of Long Beach20 minutes ago
The Wall Street Journal reported in February 2007 on concerns that quiet cars like the Prius may pose a safety risk to those who rely on engine noise to sense the presence or location of moving vehicles. Blind pedestrians are a primary concern, and the National Federation of the Blind advocates audio emitters on hybrid vehicles, but it has been argued that increased risks may also affect sighted pedestrians or bicyclists who are accustomed to aural cues from vehicles. However, silent vehicles are already relatively common, and there is also a lack of aural cues from vehicles that have a conventional internal combustion engine where engine noise has been reduced by noise-absorbing materials in the engine bay and noise-canceling muffler systems. In July 2007, a spokesman for Toyota said the company is aware of the issue and is studying options.

Low gasoline prices are partially to blame, but Toyota is also culpable. Redesigned fascias for the 2019 model are its admission that when the fourth-generation Prius debuted for 2016, it was an ugly baby. With less-angry headlights and a smoother, more conservative look, the new face and derriere can only be seen as an improvement, one applied to front-drive and all-wheel-drive cars alike. Some resurfacing inside replaces the blinding-white plastic trim that seemed dated from new with piano black, polishing the idea that after 20 years the Prius is still an aspirational product.
The Prius is a power-split or series-parallel (full) hybrid, sometimes referred to as a combined hybrid, a vehicle that can be propelled by gasoline or electric power or both. Wind resistance is reduced by a drag coefficient of Cd=0.25 (0.29 for 2000 model) with a Kammback design to reduce air resistance. Lower rolling-resistance tires are used to reduce road friction. An electric water pump eliminates serpentine belts. In the US and Canada, a vacuum flask is used to store hot coolant when the vehicle is powered off for reuse so as to reduce warm-up time. The Prius engine makes use of the Atkinson cycle.
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.
