SUBARU GLOBAL PLATFORM (SGP)
OVERVIEW
The Subaru Global Platform is the fundamental technology that underpins next-generation models from now on, together with the core technologies of the horizontally-opposed Boxer engine, Symmetrical All-Wheel Drive and EyeSight driver assist system.

Fuji Heavy Industries (FHI) say the platform offers "dynamic quality" that goes beyond high-performance, to engage emotionally with vehicle occupants.
It delivers a new level of superior driving capability, with smooth performance and outstanding drivability.

The SGP offers a distinct Subaru style of dynamic quality, producing a well-balanced vehicle with incredible driver response, no uncomfortable vibrations or noises, while delivering premium ride comfort.

Body and chassis rigidity are increased significantly between 1.7 and 2-times that of the superseded model - and huge improvements are made to the suspension and associated systems.

Combined with a lower centre of gravity design, Impreza responds accurately to the driver's steering input. Unnecessary steering corrections are eliminated and the vehicle maintains a road-hugging stance.

This level of sophisticated drivability even factors in future autonomous driving that will demand excellent straight-line stability.

The platform produces no uncomfortable vibrations or noises. A streamlined frame structure and stronger joints between various parts, are some of the improvements that increase torsional rigidity throughout the body.

High frequency sounds from the engine and transmission are largely shut out. Road noise is also reduced with the use of the input-separated mount suspension layout, and a high-rigidity chassis, considerably reducing cabin noise.

The design effectively disperses chassis resonance and distortion to significantly cut back vibrations from the steering system, floor and seats. The result is a comfort level that well exceeds its class.

Increasing the rigidity of suspension installation points allows the system to absorb shocks sufficiently, without flexing the body - producing a level of ride comfort that hides uneven road surfaces.

It delivers excellent ride comfort by effectively suppressing vibrations from the road surface and damping vibrations as quickly as possible, when driving over bumps.

Mounting the rear stabilizers directly to the chassis also helps reduce body vibrations by 50 per cent, compared to the superseded model.

Detail changes in the new platform include piping ports, that previously passed through the cabin interior structure, now moved to the outside, adding 17 mm front cabin space and 72 mm rear. The vertical plate of the side sill is positioned further out, increasing floor width.

The SGP offers linear response to driver input, such as acceleration and braking. Less body roll during cornering provides outstanding dynamic quality, greatly enhancing driving enjoyment and peace-of-mind.

All occupants can take comfort with the reassurance and enjoyable driving experience that Impreza provides.

Control and stability is also excellent, with no unstable body roll when driving through corners.

The outcome of these improvements: a flat, comfortable ride.

THE FUTURE
The single platform design concept applies to development of all future Subaru models, including electric vehicles.

It can be customised to suit each model, consistently raising the appeal of all Subarus, while still enabling the unique characteristics of each model.

In future, engines are predicted to become more varied, with hybrid, plug-in hybrids and electric vehicles increasing in demand, alongside petrol engines. The single SGP design concept caters to them all.

The use of a common design concept also leads to more efficient development of a wide range of models.

Therefore, management resources can be better used in more relevant areas.

Platform components for numerous models, previously manufactured using different types of equipment, can now be made on the same production line. This is just one example of the increased production efficiency that can be passed right down to affiliate companies of FHI.

A standardized design concept also makes it easier to run "parallel production", making numerous different models at the plant in Japan.

The platform brings the advantages of a flexible production system on a truly global scale.
