GENERAL INFORMATION

The Toyota Prius 2016 is a totally new model. It still has a hybrid propulsion system, but now it is less powerful, it spends less, its driving is more comfortable and it has more equipment related to safety. It measures 4.54 meters in length and there is a single version that costs € 29,990, which can only be added as extra leather upholstery and metallic paint. Price, equipment and data sheet . ith the Prius 2016, Toyota maintains the virtues of previous generations (this is the fourth) and improves some of the criticizable aspects when compared with non-hybrid models. Possibly, the most significant improvement is the greater acoustic insulation: now, when it accelerates a lot, the noise produced by the gasoline engine is less patent in the interior. In addition, the steering has better feel (you have the impression of driving a more precise car) and the suspension is more comfortable. Overall, the 2016 Prius is driving more pleasurable than the previous two generations ( 2004 Prius  and  Prius 2009 . The first Toyota Prius , launched in Japan in 1997, we can not say anything because we have not tested).

 

 

INTERIOR IMPRESSION

he Prius is a car with a normal amplitude except for the width available in the rear seats, which is less than usual in cars of similar length ( comparative table ). In general, there is hardly any difference with the previous model ( more information from the Prius 2009 ). In the front seats has a greater sense of space because Toyota has changed the console type “bridge” to a more conventional design, which goes below. On the contrary, this has meant that the selector lever of the change ( image ) is farther from the steering wheel and does not fall so by hand. The frames surrounding the lever, part of the steering wheel and the upper surface of the console are made of a bright white plastic ( image ) regardless of the color of the body. They are not the only bright pieces, also it is, although in this case of black color, the frame that surrounds the screen and the controls of the air conditioning ( image). This plastic gets dirty easily (or at least it is very evident when it is not perfectly clean) and produces brightness depending on the position of the sun adco travel trailer cover.

DRIVING IMPRESSION

Functionally, driving the Toyota Prius is like a car with an automatic gearbox. And it is even easier to drive than any of them because it does not give jerks in the maneuvers and moves with agility to start the march from standstill. In the Prius 2016, Toyota has increased the capacity of the battery that feeds the electric motor and the ability to recover energy in decelerations. Thanks to this, now it can circulate more time without the need to start the gasoline engine.

TECHNICAL INFORMATION

The connecting element of these components is a planetary gear . This system of transmission of movement characterizes to the Prius: it is the responsible of which before a demand of big power, the petrol engine is revolutionized of almost instantaneous way until a practically fixed regime, without keeping relation with the increase of speed of the car. On how the gear works and how it combines the rotation of the thermal engine and the two petrol engines, there is detailed information in this technical article of the Prius 2004 . The gasoline engine is the same as that of the Prius 2009 (its code is 2ZR-FXE) -1.8 liters of displacement, 98 HP of power (1 less than its predecessor), variable distribution and is  Atkinson cycle – but has has been modified to increase its thermal performance from 38.5 to 40%.  The modifications affect the exhaust gas recirculation system (which heats the engine earlier, which allows it to be stopped earlier if it is not necessary to drive the car), the intake ducts (different to produce more efficient turbulence in the combustion chamber) ) and the cooling ducts (to optimize the internal temperature of the motor). There are changes in the piston sleeves to reduce friction and, for the same purpose, Toyota has designed a new oil pump. The lubricant, of low viscosity, also helps to reduce friction losses.

HISTORY, GENERATIONS AND SPECIFICATIONS

Toyota Prius: a hybrid car that entered the market in 1997. Six years after the appearance of the first version of the Toyota Prius, the company decided to launch a new version of this model. The second-generation Prius, as soon as it appeared, won four prestigious prizes in the United States at the same time, including the best car of 2004 in North America. In the design of hybrids, there are two approaches: sequential (the engine works exclusively to charge the battery and the electric motor is responsible for the movement of the car) and parallel (the machine is driven by one of the power units, depending on the situation). As the practice has demonstrated the operation of the first Prius, the best option is the combination of both approaches. The second Prius stayed true to this principle. Apparently, therefore, the automobile’s power plant is called Toyota Hybrid Synergy Drive. Aggateincludes a 1.5-liter gasoline engine with 78 hp. and an outstanding electric motor of 68 CV   – 400 Nm.

The whole installation is developed: 113 HP. and 478 Nm. By the way, the petrol engine of this car in terms of emission of harmful substances significantly exceeded the latest EURO IV standard: the emission of CO2 in the combined cycle is only 104 g / km. In addition, it should be noted that the Toyota Prius is quite economical. In the urban cycle, fuel consumption is 8 liters per 100 km, and 5.5 liters per 100 km on high-speed motorways. Hybrid Sinergy Drive has four main modes of operation. When starting at low speeds, the engine shuts down: the electric motor driven by the battery drives the car. As soon as the speed increases, the gasoline engine wakes up (the battery stops). Part of its power is transmitted mechanically to the wheels, and another generator converts it into electricity and delivery to the electric motor (there is no transmission and the accelerator pedal always controls the electrical part of the installation). With active acceleration it uses the energy of a gasoline engine and a battery. But with a uniform movement, as well as during braking, the gasoline engine is silenced again, and the traction motor becomes a generator and charges the battery.

This happens both in the electric locomotives, which also slow down in a recoverable manner, giving energy to the contact network. The Prius II has a lot of electronics. Needless to say, ABS, EBD and VSC of the second generation, controlling the operation of the electric power steering. The electric drive of the air conditioning, which saves energy, which is not dispersed in this car, and the universal control of the cables: the electronic brakes and the accelerator pedal. Perhaps it was the lack of mechanical units that helped the designers to create an original image. Having matured and moved from the golf class to the “D” segment, the Prius is now unconditionally mono-volume. This is not a sedan, but a practical hatchback with the characteristics of a mini van. Yes, and it seems quite futuristic, unlike the example of what became “Central European” Corolla and Avensis. However, it would be strange if the car’s philosophy is not reflected in its appearance. The appearance of the car does not leave a great impression.

However, if you do not seek beauty, but prefer comfort, then you will surely enjoy the new car. Toyota Prius seats are very comfortable and meet the high standards of ergonomics. The interior of the car is very bright and spacious. A nice dashboard deserves praise, and in the center of the console you will find an onboard computer LCD monitor with a diameter of 14.5 cm. By looking at it you can get information about the state of the car and the surface of the road, you can also use it to control the audio system. If you touch the inscription “Energy” with your finger, you can get complete information about the power flow between the engine, the wheels and the battery. By touching the inscription “Consumption”, you will discover how much fuel is left in the gas tank and how many kilometers will be sufficient, as well as the mileage traveled for the trip. And this information is updated every 5 minutes. The monitor also serves as a visual map of the DVD-based navigation system. The main advantage of navigation systems with LCD screen is that they are easy to use, unlike systems with button controls.

In 2009, 12 years after the model’s debut, Toyota introduced the third generation. The second generation Prius gave the car a worldwide recognition and, during the creation of the successor of the legend, the designers faced a difficult task: to preserve the identity of the image, but at the same time to contribute something new. In comparison with the second generation, the length of the car increased only 15 mm, and the width, by 20 mm, the height of the body and the length of the wheelbase remained the same. The developers decided not to stray far from the cult “triangular” silhouette, which became the symbol of “eco-mobile”. The front and rear lights are now connected by a light blow that goes through the whole side of the body. This detail added spices to the shape of the Prius, especially soft and smooth. Another difference with respect to the previous model: the highest point of the roof moves to the center of the cabin (it used to be directly on the heads of the driver and the front passenger). Thanks to this, comfort was added in the placement of the rear passengers; Now, with a height of 170 cm, here you can not be afraid of hitting your head. The backs of the front seats became 30 mm thinner, which also added space for the knees.

The shift knob moved to the center console raised above the floor (it used to be located on the dashboard). Depending on the configuration, the car is equipped with 15 or 17 inch wheels. Another difference is the small bump on the front bumper. This is not so much a design element as a functional nuance, but it is done to better control the air flow. Third-generation Prius coefficient Cx = 0.25, which is 0.01 less than Prius II. The brand changed from NHW20 to ZVW30. This reflects the fact that the 1.8-liter Z series came to replace the 1.5-liter N-series engine. A larger engine was used to reduce fuel consumption at high speeds. The electric motor is equipped with a planetary gear. The system is complemented by an electronic oil pump and a unique exhaust heat recovery system. In general, the configuration remains the same. In addition to the “EV mode” mode (powered solely by electricity), the new model has two more: “ECO Mode” (eco mode) and “Power Mode” (for dynamic driving). With the usual driving style, with stops and climbs, the fuel consumption sensor in the car is 4 liters per 100 km. In ecological mode, you can reach an incredible level: 1.75 liters per 100 km.

The premiere of the redesigned version of the third generation model was held in Frankfurt in 2011. To slightly refresh the exterior of the Prius, the designers redesigned the front bumper, the optics of the head with LED sections and also increased the opening of the entrance of air. The interior has been updated with the finishing materials, the design of some of the elements has changed, however, the biggest innovation was the Touch & Go Plus multimedia system screen in the center panel. In addition, the Japanese have worked on acoustic insulation. When upgrading the chassis, the engineers reconfigured the suspension, making it more difficult. The Toyota Prius is powered by a Hybrid Synergy Drive engine that consists of a “four” gasoline 1.8-liter with a capacity of 99 liters. c. and 82 horsepower electric motor. In the combined cycle, the car consumes only 3.9 liters of fuel per 100 km of track, using the ECVT variator with planetary gears as transmission. Hatchback, among other things, can move exclusively with electricity, however, the energy reserve in this mode is only 2-3 km at a speed not exceeding 50 km / hour.
