The next-generation platform is designed with the future in mind, and looks ahead to 2025. Subaru’s Global Platform’s main features include enhancement in overall vehicle performance, single design concept for all ranges and adaptability to electric models in the future. The vehicle performance upgrade entails creating an emotionally engaging “Dynamic feel” that goes beyond high performance, as well as boosting the highest levels of safety.
As a standardization in design concept, Subaru intends to incorporate a single unified design for all models. Planning the main specifications of all vehicle types at one time and flexibly adjusting these basic specifications to match with the requirements of different models will strengthen the entire Subaru lineup. The new concept allows one design concept to be adapted not only to gasoline engines but also to hybrid vehicles, plug-in hybrids, electric cars, and other types of alternative power units for which demand will increase further.
Development based on a single design concept makes it possible to use limited development personnel and facilities efficiently to develop a diverse range of models. That said, it will also become possible to produce platform components for multiple models in the same one production facility, rather than manufacturing them in different factories as has been the case in the past.
The Subaru Global platform will make possible a new type of driving experience, appealing directly to the senses and offering unparalleled smoothness and comfort—all backed up by excellent performance and specifications. Specifically, the new platform will further refine Subaru’s dynamic feel in the following areas: straight line stability, noise and vibration suppression, and comfort.
For straight line stability, the new platform dramatically increases rigidity throughout the body and chassis (a 70% to 100% increase over present models) and incorporates substantial improvements to the suspension system and achieve a lower center of gravity, bringing about highly responsive steering that allows drivers to control the vehicle precisely as they want. Furthermore, Optimized frame structure and stronger joints between parts allow the new platform to improve overall torsional rigidity by 70% over present models. This distributes the resonance and distortion throughout the body, greatly reducing vibrations from the steering wheel, floor, and seats. It achieves a quietness that goes beyond vehicle class.
In addition, the new platform increases the rigidity of the suspension mounting, improving the absorption of the suspension without warping the body of the car, and providing a smooth and comfortable drive whatever the irregularities in the road surface. By mounting the rear stabilizer directly to the body, the new platform reduces the body roll of the vehicle by 50% compared to present models.
In order to sustain the world’s highest levels of safety, future Subaru models will have a lower center of gravity by 5 mm and together with the major improvements in rigidity and the evolution of the suspension system, this lower center of gravity makes possible a more stable driving experience than ever before. It also offers outstanding danger avoidance capabilities on a level with a high-performance sports car. For Passive safety, a frame structure is utilized to enable more efficient energy absorption in the event of collision and the enhanced body rigidity resulting from the increased use of high-tensile steel plates. The platform anticipates further improvements in strength and new materials and has the potential to continue to offer the world’s highest levels of collision safety by 2025.
The Subaru Global Platform is expected to be incorporated in the development of upcoming models, beginning with the next-generation Impreza, due to hit the global markets, this year.
