On April 23, GAC Toyota launched 24 models of Saina, while reducing the guide price by 10,000 yuan and attaching a 15,000 car purchase discount, it upgraded the new 8155 car machine (the same generation of the 9th generation Camry replacement car machine, and the Sena was used before the replacement), the same aviation seat of Alpha, product configuration improvement + price adjustment, which is equivalent to an "official drop" of 25,000 compared with the old model; Then there's the E-four electronic all-wheel drive system. On the basis of "global synchronization", according to the needs of our Chinese, the additional upgrade of comfort and intelligent configuration can really be called "local iteration, on-demand new", full of sincerity.
Xiaobian believes that among the 24 Saina upgrades, the most important thing is the four-wheel drive system, for the MPV with large weight and space-sensitive, the "THS intelligent electric hybrid dual-engine hybrid" and "E-four electronic four-wheel drive" structure of the "planetary gear-power split" structure are the best powertrain choices.
First, the E-four electronic four-wheel drive system has a history of more than 20 years, and the first installation was installed on Toyota's hybrid MPV in 2001, which is the most mature and best four-wheel drive system for MPV.
MPVs often have 7 people + full luggage, and four-wheel drive can greatly improve driving stability, safety and comfort. When the MPV is fully loaded, more weight is pressed on the rear axle, so that the rear axle can also output a part of the power, which can reduce the tire slippage of the vehicle, greatly improve the safety and stability of the driving - not only allow the driver to better control, but also reduce the vehicle sliding and swaying, so that the comfort of passengers in the third row is greatly improved.
Compared with traditional mechanical four-wheel drive, Toyota's E-four electronic four-wheel drive has four major advantages: "real-time response", "real-time output power", "rear axle power can exceed the front axle", and "no central driveshaft". The traditional mechanical four-wheel drive has a process of "clutch engagement/locking", no matter how fast it is, it takes more than 0.1 seconds, even at a speed of 36km/h (10m/s), which means that the road surface is more than 1 meter slippery; The response speed of electronic four-wheel drive only depends on the speed of transmission of electrical signals - the speed of light, and the delay is completely negligible. In addition, Sena's E-four electronic four-wheel drive can achieve a wide range of accurate torque distribution from 100:0 to 20:80 on the front and rear axles, making acceleration and cornering more stable, and improving climbing performance. In addition, the E-four does not require the central driveshaft of the traditional mechanical four-wheel drive, does not take up space in the car, and does not cause noise and vibration in the middle of the body.
Second, the "THS intelligent electric hybrid dual-engine hybrid" with the "planetary gear-power split" structure is the best power choice for MPVs, which is smoother, more durable, more fuel-efficient, more powerful, and can better ensure the interior space.
Different from the P1+P3 hybrid structure commonly used by other brands, Toyota's planetary gear structure has no clutch inside, which not only has a smooth power output, but also is more durable. As well as avoiding the hassle of shortening the life of the transmission oil, replacing the clutch, etc. At the same time, it realizes "high speed and low speed are fuel-efficient" and "high speed and low speed are powerful".
In addition, Toyota also chose a small-capacity power battery with a "large discharge rate"; It brings the benefits of "lightweight" and "miniaturization", and brings another important advantage to Saina - load capacity. Let's start with the table:
The whole series of Sena can achieve a load of more than 635kg. According to the 70kg adult calculation, 7 people, plus the weight of each person 20kg air consignment box standard luggage, the total weight is 630kg; The Sena can be perfectly loaded, while other MPVs in the same class can't achieve this. Matching the load capacity, there is also loading space, and the Sena is the only one among the main competitors to have a trunk sinking space design, and the third row of seats is also the only one that can be fully flattened.
The best powertrain brings the best space, the best four-wheel drive, as well as intelligent car machines, comfort and so on, and the price is reduced by 25,000! I said that the best MPV on the market is the best and most worth buying, and no one should object, right?
