After years of hard work, Toyota's TNGA architecture has been well known to people, high-tech, high efficiency, fully compatible with hybridization... A range of keywords are tagged with TNGA. However, more people want to know, is TNGA "fun"? Therefore, GAC Toyota brought a number of TNGA models to the frozen lake in Changchun, showing the unique fun of the TNGA architecture in ice and snow driving.
At the beginning of the design of the TNGA architecture, Toyota intended to enhance its handling performance in various aspects. For example, under the TNGA architecture, the floor surface of the new car is reduced by 20mm compared to the past, which of course is not only to make people feel more like driving a sports car, but also to help reduce the center of gravity, which in turn improves the stability of the vehicle.
So when the test drive team drives on the ice, even a "tall and big" guy like Veranda can dance a few laps on the ice.
Dance beautifully, too. The TNGA architecture redesigned the front and rear suspensions, especially the "sports car-grade" double wishbone independent rear suspension, optimizing the position of the suspension arm, shock absorber and longitudinal arm to improve the stability of the body and the accuracy of the handling. In the S-shaped pile winding, U-shaped bend, "8" shaped pile winding and other links, whether it is a compact Leiling or a slender Camry, the control response and attitude follow of the "rear half" are satisfactory.
The TNGA architecture not only brings about the optimization of the body structure, but also provides a stage for many new technologies to play a role.
In terms of power, Toyota "squeezed" 41% of the thermal efficiency from the new fourth-generation THS II hybrid system. The ice and snow, minus 15 degrees Celsius test drive site will not affect the normal work of this power system, as an energy storage equipment nickel-metal hydride battery is also a natural "not afraid of cold", which also makes Camry, Veranda, Leiling in this test drive activity has been maintaining sufficient power output. In particular, the stable performance of the electric drive unit provides a guarantee for the power explosion of these hybrid models when necessary. In addition, the smaller size of this powertrain, not to mention the space savings, also helps to further reduce the vehicle's center of gravity.
Snow driving is one of the most challenging driving environments for people and cars to interact with. High-precision rack and pinion electric power steering system makes steering lighter and pointing more precise. The high-tech ACA Active Steering Assist system not only improves vehicle handling and vehicle steering performance, but also reduces the burden on drivers on ice and snow roads that require rapid response. Therefore, after the vehicle completes the dance of ice and snow circle by lap, people are left with only excitement and no tiredness.
Practical, reliable, durable, this is Toyota in the hearts of the Chinese people long-term business brand image, in fact, to enhance the driving pleasure and economic durability of the product is never a two-law back, the hybrid system can save fuel, but also power; the body rigidity of the improvement will give people a more "solid" driving experience; the power battery from the trunk to the rear seat, in addition to expanding the storage space, there is also an improvement in the vehicle center of gravity effect... With the help of the TNGA architecture, GAC Toyota is presenting a new style full of "driving fun" to people.
