Sunjay J. Kapur, chairman of Indian automotive-components manufacturer Sona Comstar, died on June 12, 2025, at age 53. Kapur collapsed while playing polo at Guards Polo Club in Windsor, England. His death was confirmed by Sona Comstar and the Automotive Component Manufacturers Association of India (ACMA).
A later Surrey Coroner’s report found that he died from natural causes linked to left ventricular hypertrophy and ischemic heart disease. That finding superseded early reports that suggested a bee sting or anaphylactic shock during the polo match.

Who was Sunjay Kapur?
Kapur was the chairman and non-executive director of Sona BLW Precision Forgings Ltd., which operates under the Sona Comstar brand. Based in Gurugram, India, the company makes driveline, motor and other mobility components for global vehicle manufacturers.
Forbes estimated Kapur’s net worth at approximately $1.2 billion in 2025. His public profile, however, was tied less to personal wealth than to Sona Comstar’s expansion from a traditional precision-forgings business into a supplier of electric-vehicle and advanced-mobility systems.

Cause of death
Kapur collapsed during a polo match in Windsor on June 12. Sona Comstar’s initial statement described the event as a sudden heart attack.
In August 2025, reporting on the Surrey Coroner’s findings identified the official cause as natural causes associated with left ventricular hypertrophy—thickening of the heart’s main pumping chamber—and ischemic heart disease, a condition involving reduced blood flow to the heart muscle.
Early coverage widely repeated an account that Kapur had swallowed or been stung by a bee and suffered anaphylactic shock. The coroner’s reported findings did not establish that explanation. Police also treated the death as non-suspicious.

Kapur’s role at Sona Comstar
Kapur joined Sona BLW as a director in 2006. After the death of his father and company founder, Surinder Kapur, he became managing director in 2015. He took over as chairman in 2019.
Under his leadership, Sona Comstar increased its focus on products for electric and hybrid vehicles, including driveline systems, differential assemblies, traction motors and related mobility technologies. That transition reflected a wider change in the auto-parts industry: suppliers increasingly need to develop components for electrified powertrains alongside products for internal-combustion vehicles.
Sona Comstar’s work sits several steps behind the vehicle badge that consumers see. Its components can be incorporated into driveline and propulsion systems supplied to automakers and other vehicle manufacturers. This makes the company part of the global automotive supply chain rather than a consumer-facing car brand.
His role in India’s auto-parts industry
Kapur also held a leadership role in ACMA, the main representative body for India’s automotive-component manufacturers. He served as ACMA president and was identified by the organization as its immediate past president in 2024.

Personal background
Kapur was previously married to Bollywood actor Karisma Kapoor and later married Priya Sachdev. He is survived by family members, including children. Those details formed part of the public reporting after his death, but his principal significance to the automotive sector came from his leadership of Sona Comstar and his work with ACMA.
Why the cause-of-death correction matters
The change from early speculation to the coroner’s finding is important because the initial bee-sting account was repeated widely despite not being confirmed as the definitive cause. The later official finding points to underlying cardiac disease and natural causes, not an established allergic reaction.
For automotive readers, the broader story is the loss of a senior Indian supplier executive at a time when the sector is undergoing a major technology shift. Kapur helped position Sona Comstar for the move toward electric driveline and mobility components, connecting an established Indian manufacturing company to the rapidly changing global vehicle market.
