Price .com-quarrel amicably with Toyota, what is a "Soltra" like Subaru?

Subaru released the global development of BEV's Soltella for the first time. President Nakamura's following development team emphasizes how to create "like Subaru". Even if this idea becomes BEV, it will not change. However, changes in the automobile industry, such as electrification and connectivity, will not work on the basis of idealism alone. Not to mention global cars.

Although the content released so far is limited, what is Saltra's Subaru feature? to put it more bluntly, what is different from the Toyota bZ4X? I'd like to think about that. Reference was also made to the challenges in the global strategy that emerged on this basis.

The common development system of equal relations

First of all, Exsteria is characterized by the design of Subaru's hexagonal diamond to be aware of the sophisticated and advanced design of EV, and around the headlights is the Subaru design-the zigzag. Low light has the uniqueness of multiple projectors. This is a design that retains the Subaru design. With regard to outer packaging colors and interiors, colors that Toyota does not have are also brought to Toyota's production line (Soltra is made by Toyota factories).

The development was carried out in the form of Subaru engineers and executives seconded to the Toyota base, but they began to boil the design specifications on an equal footing, he said. It is said that his slogan is "have a good fight". Even if the design and specifications collide with each other, the foundation of the design idea is "build a good car together", and the decision is made according to this standard. For example, the design standards and strategies of vehicles are different from each other. From one side's point of view, it is impossible to configure a taximeter in this location, and running should be given priority even if the fuel consumption is somewhat reduced.

This time, Soltra and most of the components of Toyota's "bZ4X" were jointly developed. Both opinions or designs are made under the same conditions. For example, the vehicle platform Soltra is named "e-SGP". BZ4X is "e-TNGA". This is because the same thing has been given a different name, and after 2019, the ideas and opinions of both sides have been added to the EV project jointly developed by the two.

Differentiate through electronic controls such as feet and XMODE

As Toyota's "86" and Subaru's "BRZ" say, Soltra's tuning on errands is different from Toyota's. In the release of the video, it seems to have conducted their own bad road test, cross-country test, adjusted the damping rate of the damper and so on. The motor and battery control ECU are shared, and the basic operating performance control is the same, but Soltella installs XMODE to take advantage of the fine control of dual-motor AWD. The control becomes a different mechanism from the three stages of ecology, normal and strength, which is the basis of the control.

As the detailed product specifications are still in the stage of adjustment and decision before the actual release, the specific control content and numerical specifications are not disclosed. However, as the advantages of EV and electronic control, the high responsiveness and control resolution (clock frequency of ECU) is significantly higher than that of internal combustion engines, so Subaru's AWD know-how can be put into ideal form. "I realize once again that we spent so much time before igniting the fuel explosion," said Daisuke Ono, general manager of the project at Saltra's commodity planning headquarters. "

Other regeneration controls are also invested in Subaru style. There is no complete stop when the pedal is closed (the idea of stopping the car is the brake), but a regenerative lever with a paddle shift is installed. Therefore, the regeneration of the accelerator off dares to restrain the effect and decelerates actively through the paddle operation. Although it will be easier to get used to one-time control, there should be many Subaru fans who think that oar deceleration + braking is more enjoyable in terms of active control and direct sense of acceleration and deceleration.

In addition, select the wire control set in bZ4X and suspend the use of wire control in the solver. As Subaru, the first is the extremely good idea of BEV's AWD performance. The steering is not round, and the yoke handle needs to increase the gear ratio so as not to change the handle in the garage, etc. Although speed sensing can be dealt with through variable transmission ratio and lane maintenance support, it is not necessary to judge Subaru now.

Soltra who can't achieve eye contact.

Soltra pursues Subaru characteristics in detail, but also has a dead corner. This also depends on future social conditions and environmental regulations, but from a long-term point of view, the limitations of joint development may hit a brick wall.

In addition to the vehicle platform, Saltra and bZ4X, the ECU platform is also common. The specifications of the details are based on the strengths of both, while the ECU platform is based on Toyota's system. The control of the ADAS system can be called "Toyota sense of security" itself. Therefore, eye spots cannot be installed in Saltra. Although there is nothing that cannot be done in principle, because the factory is the same, it can only be paid back through the optional correspondence of the dealer.

The performance and evolution of eye points are recognized. High degree of technical completion, the use of model design and component internalization, future connected vehicles and safe driving support, when considering manned self-driving, it would be a pity if the genealogical BEV of the eye ends. It should be said that this is also a loss of technological assets.

At the present stage when the market is about to gain a firm foothold, it is reasonable to jointly develop the strategy of expanding the field of cooperation from the point of view of business speed and compliance. In the case of uncertainties in the North American BEV market, the idea of putting BEV on the market through OEM supply.

However, in the long term, even if the platform is accepted, if the software and control technology that play its value can not be unique, it can not be differentiated from the OEM supply source (Toyota). Strandis said that the EV platform is common, but the driving mode, connection function, ECU platform and other group companies are well differentiated in their respective factories.
