First of all, a HUGE thank you to Toyota of Long Beach20 minutes ago
A 2010 redesign retained similar styling but made the Prius slightly longer and more aerodynamic. A new 1.8-liter four-cylinder engine contributed to a total system output of 134 horsepower, yielding 51 mpg in the city and 48 mpg on the highway. The interior was significantly improved, as was handling. Toyota also added new drive modes, extending electric-only operation and maximizing fuel economy. Five trims and three option packages were available, and seven airbags became standard.
In August 2013, Toyota Managing Officer Satoshi Ogiso, who was chief engineer for the Prius line, announced some of the improvements and key features of the next generation Prius. This was the first generation of the Prius to use the Toyota New Global Architecture (TNGA) modular platform, which provides a lower center of gravity and increased structural rigidity. Ogiso also explained that the next-generation Prius plug-in hybrid, the Prius Prime, was developed in parallel with the standard Prius model.
Since its inception, the Toyota Prius has been among the best fuel economy vehicles available in the United States, and for the model year 2012, the Prius family has three models among the 10 most fuel-efficient cars sold in the country as rated by US Environmental Protection Agency (EPA). After the Honda Insight first generation was discontinued in September 2006, the Prius liftback became the most fuel-efficient car sold in the American market,  until it was topped by the Chevrolet Volt in December 2010, as the plug-in hybrid was rated by EPA with an overall combined city/highway gasoline-electricity fuel economy of 60 mpg‑US (3.9 L/100 km; 72 mpg‑imp) equivalent (MPG-e). According to the EPA, for the model year 2012, and when only gasoline-powered vehicles are considered (excluding all-electric cars), the Prius c ranks as the most fuel-efficient compact car, the Prius liftback as the most fuel-efficient midsize car, and the Prius v as the most fuel-efficient midsize station wagon.
On the inside, Toyota has replaced the white plastic interior trim with black glossy and semi-glossy finishes. The Prius lineup has gone through a name change, too, dropping the numbered trims with a more traditional Toyota name lineup of L Eco, LE, XLE and Limited. Feature content remains largely unchanged, which unfortunately also means Apple CarPlay is not yet available. On the plus side, the Toyota Safety Sense P suite of advanced safety features is standard on all Prius trims.
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.
