SUBARU's first BEV* to be launched globally.
The name combines the Latin words
for "sun" and "earth."
With this Subaru SUV,
equipped with excellent AWD performance,
we hope to enjoy the outdoors together
with our customers and enrich
our coexistence with nature.
*BEV = Battery Electric Vehicle
This is a world premiere presentation by Tomomi Nakamura,
President and CEO and Daisuke Ono, Project General Manager.
It introduces our development concept behind SOLTERRA.
SUBARU's aim in developing SOLTERRA
was to create a car that provides the new value BEVs can offer
and SUBARU's values of enjoyment and peace of mind,
while being used comfortably on a daily basis.
BEVs are expected to have "an advanced feel that is typical of next-generation vehicles," "differences from vehicles with internal combustion engines," and "enhanced connectivity," and SOLTERRA is responding to each of these expectations.
Both the exterior and interior of SOLTERRA are filled with an advanced feeling. It expresses a sense of innovation through a variety of design features, including a seamlessly molded hexagon grille, C-shaped headlights that are part of Subaru's signature, and a cockpit with top-mounted meters. The seamless console is easy to operate with plenty of storage, and the large glass roof further enhances the sense of openness. It is not just the design that is futuristic. One such example is SUBARU's first fully automatic park assist function. Steering, gear shifting, accelerating, and braking are all system controlled, and the car parks itself automatically.
The compact motor unit, eAxle, allows for a design with a short overhang and a long wheelbase for more legroom. The BEV also responds well to accelerate seamlessly for a driving experience that only an electric vehicle can provide.
SOLTERRA uses a multimedia system with a large, 12.3-inch screen and can link to smartphones using a wireless system. It is also equipped with a contactless charger that can be used to charge smartphones. In addition, a digital key function has been adopted. Remote operation of the fully automatic park function from outside the vehicle is also available. We have given a lot of thought to convenience in the SOLTERRA's design and created a smartphone app that allows you to operate the windows, lock/unlock the doors, and precondition the cabin remotely. We used advanced technology to adequately meet people's expectations of BEV.
We committed ourselves to creating a BEV that had SUBARU's fun drive performance, AWD control offering peace of mind in any environment, top-class safety, and ease of use.
We developed a dedicated BEV platform, the e-SUBARU Global Platform, that achieves greater strength and rigidity than before. This contributes to improved handling stability, achieving SUBARU drive performance that responds exactly as the driver intends. There are also three drive modes that control the output in response to operation of the accelerator: ECO, NORMAL, and POWER. The strength of the regenerative brakes can be controlled with the steering paddle switches, which is another example of where SUBARU ensured the car drives exactly as the driver intends.
Using a new AWD system, separate motors control the front and rear wheels to increase the degree of freedom in the distribution of front and rear drive power. This maximizes the grip of all four tires, achieving a drive performance offering total peace of mind. The power train is laid out symmetrically, offering the straight-line stability and reassuring driving experience found in SUBARUs. The X-MODE AWD control system used in SUBARU's SUVs, and the newly developed Grip Control work to refine the vehicle's rough road capability.
BEVs tend to be heavy due to their batteries, but SOLTERRA has achieved high collision safety even with a lightweight body by optimizing the strength of the materials used in each part of the vehicle. In addition, in the event of an accident, the robust body frame structure will protect not only the passengers but also the high-voltage electrical components.
The cargo space is designed to provide space suitable for an SUV and can hold four golf bags or three large suitcases. The height of the cargo floor has been kept low to ensure convenience when loading. There is also ample storage space in the center console. In addition, various buzzer and indicator sounds are the same as those used in other Subaru vehicles to make the driving experience more familiar for existing SUBARU customers.
Concerns about BEVs, such as "cruising range" and "battery degradation," have been addressed with the SOLTERRA.
The SOLTERRA is equipped with a large-capacity battery that provides enough cruising range to cover the distances of daily use, and it is also compatible with DC quick charging, which reduces the inconvenience of long-distance travel with a short charge. In addition to a heated steering wheel and seats that warm up quickly with little power, a heat pump air conditioner with low power consumption is used. This minimizes the impact on the cruising range.
The internal structure has been improved to maintain sufficient battery capacity even after 10 years, and innovations in charge control have been incorporated.The result is a BEV that can be used without worry.
