Joint Development of Suspension Module for EVs with GLM

Suspension Module EVs GLM

Toyo Tire & Rubber Co, Ltd announced that it had recently agreed and started to tackle the joint development of a suspension module for EVs (Electric Vehicles) with GLM Co, Ltd, an EV manufacturer, to meet society’s future mobility demands.

Collaborative Development of Suspension Module for Electric Vehicles with GLM

The development of EVs powered by electric motors has accelerated worldwide, with many different automobile manufacturers mapping out their own mass production plans in quick succession. Because EVs run so much quieter, the performance requirements for the components used in EVs differ from those for combustion engine vehicles. In particular, any rubber products made for EVs must provide a different level of functionality and performance from conventional vehicles, such as being much quieter, and optimal damping control to vibration generated from such sources as uneven road surfaces and the e-motors.

GLM – the company’s joint development partner – launched full-scale mass-production of its Tommykaira ZZ electric sports car in October 2015. The following year, GLM attracted much attention when it presented the concept car GLM G4 as a futuristic electric supercar at the Paris Motor Show 2016. GLM not only develops and distributes complete vehicles, but also sets up a ‘platform business’ providing a platform that is considered the heart of the vehicle or the parts thereof, developmental expertise and a collaborative relationship with automotive companies and organisations (GLM Ecosystem) for non-automotive manufacturers as a core of its business.

Toyo’s automotive products, such as tyres and air suspension, are seen as an integral part of vibration control and play an important role in maintaining quietness, comfort and safety. It says it would promote the development of a ‘modular suspension system for EVs’ that combines Individual purpose products, including tyres, as part of its business source development with a close eye on future mobility.   The primary parts being promoted for development by the companies are ‘active air suspension to ensure a smooth flat ride’. Toyo has launched development of the modules to be mounted on vehicles in line with its mid-term vision with an eye on commercialisation within 2020. This is managed under the plan for joint development of a next-generation active suspension in which electronic control technology is embedded and applied to air suspension while receiving the necessary information regarding active suspensions, suspension systems and elemental technologies for the overall vehicle, and support related to knowledge accumulated as an automobile manufacturer from GLM.

From this fiscal year, Toyo has begun to tackle business focused on ‘mobility’ including automotive tyres and components as a management entity. It takes the view that jointly developing product modules for EVs with GLM as a partner would contribute to expanding the potential for deepening and advancing the future vehicle. The company aims to become a supplier that could propose greatly added value by accumulating experience in total design and packaging of suspension modules specifically to resolve the unique technical issues confronting EVs through its collaboration with GLM.

Both companies released statements to mark the recent launch of this joint development.

  • Hiroyasu Koma, Representative Director & President, GLM Co, Ltd.

Toyo Tire & Rubber Co, Ltd has exceptional expertise in air suspension technology. They are keen to develop new products as implied by their excellent development resources. Having such a development partner enables us to add attractive technology to our exciting products. We believe that the flat-ride technology that we are jointly working to develop would become a core technology for electric vehicles, given their superior quiet performance. This technology is becoming the de facto standard for premium segment vehicles, the share of which has grown in line with global economic growth. I expect massive needs for general vehicles in emerging countries where road conditions are insufficient and transportation for people and luggage once the cost is reduced following a shift to mass production.

GLM is an emerging EV manufacturer born out of Kyoto University’s electric vehicle development project. GLM has succeeded in developing and bringing EVs to production from scratch, and thus has a frontier spirit in searching for future vehicle options through partnerships with a variety of companies. I feel a sense of kinship between GLM’s progressive spirit and creativity and our corporate culture. We will maximise our technological potential, achieve a new level of integrated performance for each proven component and would like to realise modular production of indispensable and value-added suspension system components for our future vehicle.



随着电动引擎驱动的电动汽车在全球发展加速,不同的汽车制造商快速且接连地制定了他们的批量生产计划。由于电动汽车行驶起来比较安静,电动汽车所需要的零部件不同于那些使用内燃机的汽车。尤其是任何为电动汽车制造的橡胶产品必须提供与传统汽车不同程度的功能和性能 ,比如必须更安静、优化的阻尼控制,减少来自不均匀路面和电动引擎的振动。

东洋的合作伙伴GLM曾在2015年推出全尺寸的批量生产Tommykaira ZZ电动跑车 。第二年,GLM在 2016年巴黎汽车展中展示了他们的未来概念车GLM G4电动超跑。GLM不仅只是开发和经销完整汽车,也建立起一个“业务平台”,提供被认为是汽车中心或 其部分、开发专长、与汽车公司和非汽车制造商组织(GLM 环保系统)合作,作为其核心业务。



在这个财政年,作为管理企业的东洋轮胎开始注重“流动性”,包括汽车轮胎和零部件。它认为与GLM联手发展电动汽车产品组件,将有助于深化和推进未来汽车的潜能。该公司旨在通过与GLM的合作,成为一个能够提供巨大附加值的供应商, 透过其累积的悬挂组件的整体设计和包装经验,特别是在解决电动汽车所面对的独特技术问题 。
