Sona BLW Precision Forgings Limited (Sona Comstar) has signed definitive agreements with Japan-based DENSO Corporation to establish two joint ventures focused on the development, design, manufacturing, and marketing of advanced electric and hybrid powertrain systems for multiple vehicle segments.
The partnership brings together DENSO, a global leader in automotive technology and innovation, and Sona Comstar, one of India’s leading manufacturers of electric vehicle (EV) components. The collaboration is driven by a shared vision of transforming the electric mobility landscape by delivering world-class electric powertrain solutions that set new benchmarks in performance, quality, reliability, and sustainability.
Under the joint venture, DENSO will contribute its global expertise in electrification technologies, advanced product engineering, and research and development capabilities. Sona Comstar, on the other hand, will leverage its engineering excellence, cost-efficient manufacturing, agile execution, and strong understanding of the Indian automotive market. By combining their complementary strengths, the two companies aim to develop scalable, high-performance, and cost-effective electric and hybrid powertrain systems that cater to the evolving needs of the automotive industry across domestic and global markets.
The global automotive industry is undergoing a significant shift towards electrification, and similar trends are also playing out in India across vehicle segments. This transition is creating the need for advanced, reliable and cost-effective electric and hybrid powertrain systems. Leveraging India’s growing position as a global automotive manufacturing and innovation hub, the proposed joint ventures will be anchored in India and will develop products that meet global standards of quality and performance.
The partnership will be implemented through two strategic joint ventures. One joint venture will focus on highvoltage liquid-cooled traction inverters, traction motors and generators for electric and hybrid four-wheelers and larger vehicle applications. The other joint venture will focus on air-cooled traction inverters, traction motors and generators, and e-Axles for electric and hybrid two-wheelers and three-wheelers.
Transaction Overview
Joint Venture for Electric and Hybrid Powertrain Systems
Sona Comstar and DENSO will establish a joint venture to develop and manufacture advanced electric and hybrid powertrain systems for passenger vehicles, commercial vehicles, and other high-voltage applications with four or more wheels. As part of the collaboration, the two companies have signed a Joint Development Agreement (JDA) to jointly design and develop high-efficiency liquid-cooled traction inverters, traction motors, and generators for electric and hybrid vehicles.
To commercialize these technologies, the partners will set up a manufacturing joint venture in India. DENSO will hold a 51% equity stake and have management control of the venture, while Sona Comstar will own the remaining 49% stake. Sona Comstar will contribute its engineering expertise, manufacturing capabilities, and well-established supply chain network to support the venture’s operations and growth.
JV for Electric and Hybrid Powertrain systems for two-wheeler and three-wheeler applications
Both parties will establish another joint venture which will have Sona Comstar transferring its existing electric traction motor and controller business for two-wheelers and three-wheelers, into its wholly owned subsidiary through slump sale. Subsequent to this transfer, DENSO, directly or through its affiliates, will acquire 49% equity stake in that entity at an enterprise value of INR 17,500 million, while Sona Comstar will retain the balance 51% and management control.
This joint venture will engage in the business of air-cooled traction inverters, traction motors and generators and e-Axles for electric and hybrid two and three-wheelers. This partnership aims to expand product offerings through accelerated innovation and create opportunities to serve a broader customer base.
Both DENSO and Sona Comstar shall license intellectual property and know-how to their respective majority owned joint ventures against payment of royalty.
The transaction is subject to receipt of relevant regulatory approvals and customary closing conditions mutually agreed between the parties in the definitive agreements.
Commenting on the strategic development, Mr. Vivek Vikram Singh, MD and Group CEO of Sona Comstar, said: “We have always believed that the future of mobility will be defined by companies that continuously invest in innovation, product development and industrialization of advanced technologies. This partnership marks an historic milestone in Sona Comstar’s journey as a mobility technology company and reflects the capabilities we have built across advanced electric powertrain systems over the years. DENSO is a company we have immense respect for, as they have been at the forefront of automotive innovation globally for decades with deep expertise in electrification technologies. We are honored and delighted to partner with DENSO to bring together the complementary strengths of both companies and build advanced electric and hybrid powertrain solutions for four-wheelers and larger vehicle applications. This partnership will also accelerate the growth of our existing electric powertrain business for two and three-wheelers by strengthening our capabilities across the powertrain value chain and enabling us to serve a broader set of customers.”
Mr. Tsuneo Maebara, Head of Powertrain Systems Business Group at DENSO Corporation, said: “The electrification of mobility represents a major transformation that will continue to evolve in response to the diverse needs of customers and society across the world. India, in particular, is an important region where diverse forms of mobility coexist and electrification is advancing at significant scale. Sona Comstar is a mobility technology company with a global business presence, serving a broad range of customers, and having boldly transformed itself alongside the rapid evolution of the mobility market—from conventional vehicle technologies to solutions for both two- and three-wheelers and passenger electric vehicles. Through this partnership, we will bring together the respective strengths that both companies have built over the years to provide electrification solutions that address the diverse needs of customers in India. By harnessing new competitive strengths created through synergies across the two companies’ products, technologies and business foundations, DENSO will further advance and accelerate its electrification business. We will also build on the outcomes achieved in India to deliver value that meets a broader range of customer needs in the future.”
Deloitte India, Trilegal and KPMG India acted as financial, legal and diligence & tax advisors respectively to Sona Comstar for this transaction.
