I intelligent mode is a mode designed for economy and fuel saving. Its biggest feature is that it weakens the power output of the engine by about 20%. According to the manufacturer, the power output of this 3.0 engine becomes equivalent to 2.0 in I mode. This is in exchange for excellent fuel-saving performance. In this mode, the throttle response is moderate, the speed is slow, and the gearbox will not downshift easily. Although the highest speed can be used, the power output at the limit is not as strong as 3.0. Using this mode to drive in urban road conditions, you can get very low fuel consumption (for a 3.0-liter car), and because of the soft power output, novice drivers are also very safe.
S sport mode is the default mode after every start of the car, that is, the "normal" mode. It allows the 3.0 engine to output all power, but the output characteristics of the engine, gearbox program and throttle response will take into account the requirements of easy driving, power and fuel economy. It can be said that it is the most comprehensive Legacy 3.0, which is suitable for daily driving and has a relatively high speed.
The last mode is the exciting S # "Super Sports" mode. Compared with S mode, the maximum horsepower and torque of the engine have not been further increased, but the torque output curve has changed, and the power emerges more quickly. At the same time, the automatic gearbox will also give the most active cooperation, and the electronic throttle response will also enter the most sensitive state. At this time, the throttle of Legacy 3.0 is extremely sensitive and the acceleration is rapid. Driving violently on the mountain road and overtaking suddenly on the expressway will make people feel comfortable and people and vehicles react in one.
The three modes of SI drive are realized by changing computer program, engine valve lift and fuel injection. Its basis is to realize electronic control of all components, and then link all components together. Subaru's engineers said that they were the first automobile factory to completely link the engine, gearbox and throttle through a system, and related technologies were still being patented. To put it simply, SI-Drive divides the engine output into two stages. I mode is a limited weak power output mode in exchange for excellent fuel-saving performance. S mode is the output mode that returns to the normal level, and other parts also work in the normal state; Under the condition of constant output power, S# mode makes all parts react faster, thus making the whole vehicle more radical. It is not difficult to separate these three modes, but it is not easy to realize the change of the three modes in a car. Therefore, the factory's general introduction to SI-Drive is "1 3 engine" (three engines in one).
SI-Drive is very simple to use. The center console knob is in I mode when pressed, in S mode when rotated to the left, and in S # mode when rotated to the right. In addition to this knob, there is a conspicuous S # shortcut key at the lower right of the steering wheel. No matter which mode you are in, as long as you press this button, you will immediately switch to S # mode, which is suitable for situations that require sudden acceleration and emergency overtaking. The switching reaction between the three modes is very fast, almost instantaneous, and there is also a corresponding display on the instrument.
Practical significance of silicon drive
Well, I've introduced the working principle of SI-Drive system for a long time. If you really don't understand, I'll try to say it briefly now. The function of SI-Drive system is to endow the heritage with three different personalities-convergence, balance and licentiousness. You still don't know the character of a car? That's even simpler: with the SI-Drive, this Legacy 3.0 can save fuel at slow speed and be full of power at fast speed, but it is almost impossible for a normal car to have both contradictory advantages at the same time. This is good, right? But you still can't think of the use of such a car. Then think about it. Legacy 3.0 is originally a powerful car, only suitable for people who emphasize sports driving. Now with the I mode of SI-Drive, novices can drive safely without worrying about the danger caused by excessive power. So you buy this car, you and your wife can drive it, your husband has a good time, and your wife won't object. This is the best meaning of "three cars in one".
2.0 is the main sales force.
Only the 3.0R version of the new Legacy has the SI-Drive system, and another eye-catching equipment only available in the 3.0R version is the steering wheel shift paddle. These two kinds of metallic paddles can bring a purer sense of driving engagement, and are also essential designs for a new generation of "driving". In addition, Legacy 3.0R also added a Chinese voice navigation system. The LCD navigation screen on the center console can also be used to display fuel consumption, throttle opening, driving information, and even include calculator and memo functions. There are indications that the new Legacy 3.0R is making every effort to increase its selling point.
After introducing Legacy 3.0R with SI-Drive and a number of new devices, let's not forget the new Legacy 2.0r. Its appearance and interior are almost the same as that of 3.0R (only the grille under the front bumper is slightly different), but there are no devices such as SI-Drive system, steering wheel shift paddles, satellite navigation, LCD multifunction computer, and passenger seat electric seat. However, we are still quite sure that this 2.0R (only 266,5438+0.8 million), which is 80,000 yuan cheaper than 30R, will be the main sales force of Legacy. Most buyers who enter the exhibition hall will eventually pay for the lower-priced and more affordable 2.0R after learning about the fun technology of 3.0r. However, it is worthwhile to spend a lot of time introducing the Legacy 3.0r, because its SI-Drive system, steering wheel shifting, high equipment and high performance are all aimed at enhancing the image of the entire Legacy car system, which makes people feel that it is technically excellent and unique when they talk about Subaru Legacy, thus standing out from the mid-level cars. So when you buy Legacy 2.0R, all you have to do is step on the gas pedal to get ahead of others every time you wait for a red light side by side with other cars, because the side and tail of Legacy 2.0R are exactly the same as those of 3.0R, and no one can tell the difference.
In this way, Subaru found a good way to increase the sales of mainstream models by its own strength-technology.
Advantages: SI-Drive system realizes both power and fuel economy for the first time; Driving control is still outstanding in the same class.
Disadvantages: the appearance seems to be worse than before; The interior design is also slightly messy; Suspension requires high road conditions.
