Electric Ambassador Taxi Prototype Unveiled in Kolkata
Updated: Aug 26
Date: July 11, 2026
Location: Kolkata, India
News Summary
A team at Jadavpur University has developed a working prototype that converts Kolkata's iconic Ambassador taxi into an electric vehicle (EV), offering a potential pathway to extend the life of ageing commercial vehicles while reducing emissions. The project, developed with support from Damodar Valley Corporation (DVC) and industry partners, is now moving toward testing and regulatory certification before any commercial rollout.
What Was Announced?
One of Kolkata's most recognizable symbols—the yellow Ambassador taxi—could receive a new lease of life through electric vehicle retrofitting instead of being scrapped.
Researchers from Jadavpur University's Department of Power Engineering, working with Damodar Valley Corporation (DVC), have unveiled a prototype electric Ambassador taxi created by replacing the vehicle's diesel powertrain with an electric drivetrain. The project aims to demonstrate that older internal combustion engine (ICE) vehicles can be converted into zero-emission electric vehicles while preserving their structural integrity.
The prototype was publicly showcased on May 29, 2026.
Unlike manufacturing a brand-new EV, the retrofit approach seeks to reduce waste, lower conversion costs, and help commercial fleet operators transition toward cleaner mobility.
Key Highlights
Project: Electric retrofit of Kolkata's Ambassador yellow taxi
Developed by: Jadavpur University Department of Power Engineering
Industry Partner: Damodar Valley Corporation (DVC)
Commercial collaborators: Pointo and MSME partner P2G Mobility have been associated with aspects of commercialization and deployment plans, according to project reports.
Prototype unveiled: May 29, 2026
Estimated city driving range: Around 200 km per charge (project estimate)
Technology: Electric motor, battery pack, electronic controller and smart monitoring system
Future step: Automotive Research Association of India (ARAI) testing and certification before commercial deployment
Company and Project Statement
According to the project team, the initiative focuses on giving ageing commercial vehicles a second life instead of sending them for premature scrappage.
Officials involved in the project have said the retrofit platform is intended to reduce emissions while lowering the financial burden on taxi owners compared with purchasing a new electric vehicle. The project also explores battery-swapping and digital monitoring technologies for commercial fleet use. These remain project objectives and will require further validation through certification and field testing.
Industry Context
India has accelerated its push toward electric mobility through central and state-level incentive programmes, but replacing millions of existing petrol and diesel vehicles remains expensive.
Retrofitting older vehicles offers an alternative pathway, particularly for commercial fleets where purchasing entirely new EVs may not be financially viable.
Kolkata's yellow Ambassador taxis have served the city for decades and remain one of India's most recognizable automotive icons, although their numbers have steadily declined due to stricter emission norms and the ageing fleet.
If regulatory approvals are secured, the Jadavpur University project could become a model for extending the useful life of legacy commercial vehicles while reducing urban emissions. However, widespread adoption will depend on certification, economics, charging or battery-swapping infrastructure, maintenance networks, and state transport regulations.
What It Means
For Taxi Owners
Potentially lower transition cost than buying a new electric taxi
Opportunity to continue operating existing vehicles if approved by regulators
For Consumers
Cleaner urban transportation with reduced tailpipe emissions
Preservation of Kolkata's iconic yellow taxi heritage
For India's EV Industry
The project demonstrates how retrofit technology could complement new EV manufacturing, particularly for commercial fleets where extending vehicle life may improve affordability.
Traditional vs Electric Ambassador Taxi
Feature | Traditional Ambassador Taxi | Electric Retrofit Prototype |
Powertrain | Diesel | Electric |
Tailpipe Emissions | Yes | Zero tailpipe emissions |
Fuel | Diesel | Battery electric |
Estimated City Range | N/A | Around 200 km* |
Technology | Conventional | Smart monitoring, electric drivetrain |
Status | Existing fleet | Prototype under testing |
Before commercial deployment, the prototype must undergo:
Automotive Research Association of India (ARAI) testing
Regulatory approval
Road validation
Safety certification
Only after these processes can commercial retrofit kits be deployed on a larger scale. The developers have not announced a confirmed market launch date.
