Sona Comstar, DENSO Join Forces for Electric & Hybrid Powertrain JVs

Sona Comstar and Japan's DENSO have announced two joint ventures in India for electric and hybrid powertrain systems. The first JV, with DENSO holding 51%, will focus on high-voltage systems for passenger and commercial vehicles. The second JV, with Sona Comstar holding 51%, targets two- and three-wheeler powertrain systems. The partnerships aim to combine DENSO's electrification expertise with Sona Comstar's manufacturing capabilities.

Sona Comstar, DENSO to form two JVs for electric, hybrid powertrain systems

New Delhi, July 22

Sona BLW Precision Forgings Ltd, popularly known as Sona Comstar, on Wednesday announced definitive agreements with Japan's DENSO Corporation to establish two joint ventures focused on developing, manufacturing and marketing advanced electric and hybrid powertrain systems for multiple vehicle segments.

The partnership will combine DENSO's expertise in automotive electrification, product engineering and research and development with Sona Comstar's engineering capabilities, cost-competitive manufacturing and understanding of the Indian automotive ecosystem.

The proposed joint ventures will be anchored in India and will develop powertrain products aimed at meeting global standards of quality and performance, as the automotive industry accelerates its shift towards electrification.

One of the joint ventures will focus on high-voltage liquid-cooled traction inverters, traction motors and generators for electric and hybrid passenger vehicles, commercial vehicles and other larger vehicle applications. DENSO will hold a 51 per cent stake and have management control, while Sona Comstar will hold the remaining 49 per cent.

The second joint venture will focus on electric and hybrid powertrain systems for two-wheelers and three-wheelers, including air-cooled traction inverters, traction motors and generators and e-Axles.

For this venture, Sona Comstar will transfer its existing electric traction motor and controller business for two-wheelers and three-wheelers to its wholly owned subsidiary through a slump sale. DENSO, directly or through its affiliates, will subsequently acquire a 49 per cent stake in the entity at an enterprise value of Rs 17,500 million, while Sona Comstar will retain a 51 per cent stake and management control.

Commenting on the development, Sona Comstar MD and Group CEO Vivek Vikram Singh said, "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."

He said the partnership would bring together the complementary strengths of the two companies to develop advanced electric and hybrid powertrain solutions for four-wheelers and larger vehicles, while also accelerating the company's existing electric powertrain business for two- and three-wheelers.

DENSO Head of Powertrain Systems Business Group Tsuneo Maebara said India was an important region where diverse forms of mobility coexist and electrification is advancing at significant scale.

"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," Maebara said.

The transaction remains subject to relevant regulatory approvals and customary closing conditions. Both companies will license intellectual property and know-how to their respective majority-owned joint ventures against payment of royalty.

Great to see Indian companies getting international recognition. The focus on two-wheelers and three-wheelers is smart—that's where India's real EV potential is, think of all the auto-rickshaws and scooters! But I'm a bit concerned about the 51% control going to DENSO in the first JV. Shouldn't Indian companies lead in their own backyard?

As someone working in automotive, this is a positive sign. The combination of DENSO's R&D and Sona's cost-effective manufacturing could produce world-class powertrains at competitive prices. Hope this leads to more affordable EVs in India rather than just export-focused products.

Finally some concrete action on EV components! India's auto sector has been talking about electrification for years, but these JVs show real commitment. The Rs 1,750 crore valuation for the two-wheeler business seems quite healthy. Let's hope regulatory approvals come quickly and this isn't stuck in delays.

This reminds me of Maruti-Suzuki's JV that transformed Indian cars. But for EVs to really take off, we need charging infrastructure and cheaper batteries too. A good step, but not the silver bullet. Hope the government also focuses on the ecosystem around these powertrains.

As an auto enthusiast, this excites me but I'm also cautious. Japanese companies are known for quality but also for tight IP control. What does Sona really get out of this besides some royalty? Hope the terms are balanced. Still, any move towards Made in India EV components is welcome! 🇮🇳
