Toyota Entune debuts the first-ever support for engaging mobile apps, such as Bing, OpenTable, and movietickets.com, along with accessing useful travel-related services, such as live weather, traffic, fuel information (location and price), stocks, and sports. Toyota Entune brings the largest selection of music options available to a vehicle, including iheartradio’s 750+ stations, and Pandora’s personalized music service.
The audio systems combined with Entune feature a best-in-class, advanced conversational voice recognition system that helps the driver to stay focused on the road by eliminating the need to memorize thousands of voice commands. The system will also allow for audio read-back and replay capabilities for text messages, with the ability to respond by pre-set “Quick Reply Messages” such as: “I’m driving and will reply later.”
With a balance between outstanding spaciousness, refined style, and smooth aerodynamics, Toyota Prius v has a low 0.29 coefficient of drag, which does not inhibit the vehicle’s convenient packaging. It is a new vehicle designed from the ground up, with a shape that evolved from Prius rather than being an elongated version.
Keeping air resistance low is the familiar triangular Toyota Prius silhouette, adapted to a larger size. A flush surface from the front of the vehicle through the front pillar works with side “aerocorners” for exceptionally clean airflow. The smooth front sheetmetal blends into a carefully designed roof and cabin, leading to an optimized cabin-end shape that acts to converge side and roof airflow. Wheels and wheel caps are designed with aerodynamic effects in mind. These measures and others also have the beneficial effect of suppressing wind noise.
Enhancing the clean, low wind-resistance design are materials that keep the Toyota Prius v relatively light and easy to move. The door panels are foam-injected with polypropylene and the deck board with light-weight urethane to produce a weight savings of approximately 20 percent. Significant weight reduction is also achieved through the use of high-tensile grades of steel throughout the body along with aluminum in key body panels and systems.

High-strength steel sheets and bars used throughout the body to ensure a light, yet highly rigid platform structure.
Also available, and a Toyota-first, is a resin Panoramic View Moonroof with power retractable sun shades that provides an open atmosphere in the cabin with a 40-percent reduction in weight as compared to conventional glass roofs of the same size, and excellent heat insulation performance. This improved thermal resistance means the engine needs to run less to preserve comfortable ambient temperatures, which in turn enhances fuel efficiency. The moonroof has an electrically operated shade system with a jam protection function.
Available LED headlamps work to improve visibility while reducing current draw. They use projector lenses to offer long-range visibility and are designed to be virtually maintenance free for the expected life of the vehicle.
Toyota Prius v features a climate control system with enhanced cooling capability to cope with a larger cabin. The system uses an electric compressor, so the air conditioning can run without depending on the engine, and improved component design for better maximum-demand cooling performance.
Proven Hybrid Synergy Drive System Now More VersatileThe Hybrid Synergy Drive system in the Toyota Prius v is essentially the same as the current third-generation Toyota Prius. The system uses two high-output motors, one 60kw (80 hp) unit that mainly works to power the compact, lightweight transaxle and another smaller motor that mainly works as the electric power source. Maximum motor drive voltage is 650 volts DC. The proven and practical nickel-metal hydride battery pack is the same as on the third-generation Toyota Prius liftback, but with a cooling duct located under the rear seat.
As with current-generation Toyota Prius cars, Hybrid Synergy Drive is a series-parallel hybrid system that can provide power either from the engine alone, or the motor alone, or any mix of both. A hybrid control computer manages the system so that optimum power is delivered according to driver demand. It uses a start/stop system and regenerative braking to conserve fuel and recharge the battery upon deceleration.
Hybrid Synergy Drive is built around a specially adapted, efficient 98-horsepower1.8-liter four-cylinder engine that runs on the Atkinson cycle and contributes to a total system horsepower of 134. Key components include an electric water pump that requires no belts, and an exhaust gas recirculation (EGR) system that helps warm the engine quickly, reducing fuel consumption when the engine is cold. Compact and light weight, the engine produces minimal noise and vibration. Sophisticated valve control, injector design, and other technologies reduce emissions to allow the Toyota Prius v to qualify for SULEV and Tier2 Bin3 emissions standards.

Four Driving ModesIn addition to the standard driving mode, Toyota Prius v drive system also includes an Eco driving mode, an EV driving mode, and a Power mode. In Power mode, enhanced mid-range response enables easier coping with slopes and mountainous terrain. In EV mode, the Toyota Prius v can run on battery power alone for short distances and lower speeds, up to about a mile. In Eco driving mode, the engine management system prioritizes fuel economy, managing throttle response and limiting power consumption from the air conditioning.
Pitch and Bounce Control; Better Ride, Better HandlingA new feature, Pitch and Bounce Control, works with suspension enhancements to improve ride comfort and control. Because the Toyota Prius v is a larger vehicle more likely to carry loads and passengers, front and rear suspension components have been redesigned to improve handling and ride quality. Front coil-over spring and damper capacities have been significantly increased and a new upper support has been designed. The steering gear has been attached to the front suspension member, and the stabilizer bar repositioned for more responsive steering feel and enhanced ride comfort.
In the rear, a torsion-beam suspension design has been fitted with appropriately tuned springs and dampers. The new rear-suspension system is designed to help ensure stability and ride comfort, and it has a lower mounting point to improve luggage space.
Pitch and Bounce Control uses the torque of the hybrid motor to enhance ride comfort and control. The system, working with wheel-speed sensors and in tune with the suspension, helps suppress bounce and toss motions to improve comfort for occupants. Because it helps control the balance and posture of the vehicle as a whole, it also functions to improve handling response.
Standard wheels are 16 inches in diameter, with 17-inch wheels available as an option.
Cutting Edge Safety and SecurityA variety of available and standard features maintain the Toyota Prius tradition of premium-level equipment packaging. Not least among them is a broad suite of advanced features, both active and passive, that are designed to help maximize occupant safety.
The all-new Toyota Prius v platform is designed with a force-absorbing body structure. Increased use of high-strength steel, notably in the front frame members, is a key part of providing a strong body structure without increasing weight. Helping to protect the cabin from side and rear intrusions are similarly engineered reinforcements using high tensile steels, all designed to disperse energy strategically throughout the vehicle to help protect passengers.
Like all Toyota models, the Toyota Prius v will feature Toyota’s Star Safety System™ standard, which includes Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD) and Brake Assist. It also features the standard Smart Stop
Technology brake-override system.
An electronic tire pressure monitoring system is standard equipment, and there are seven airbags strategically located about the cabin, including a knee airbag for the driver. New driver and front-passenger seat design helps lessen the possibility of whiplash injury during certain types of collisions while minimizing weight. A new Vehicle Proximity Notification System helps alert pedestrians and cyclists of an oncoming vehicle under certain conditions by emitting a small warning sound.
An available Pre-Collision System (PCS) retracts seatbelts and applies the brakes in certain conditions when a frontal crash is unavoidable. It is paired with Dynamic Radar Cruise Control.
Another available safety system, Safety Connect, can access a call center with a live operator who can dispatch police and emergency vehicles. The system combines automatic collision notification and a stolen vehicle locator feature, which can track the location of the stolen vehicle via GPS and help guide police to recover it.
