Tata Motors' new Acti-EV platform debuts on Punch EV

Tata Passenger Electric Mobility (TPEM), the electric vehicle arm of Tata Motors, today introduced its first advanced ‘Pure EV’ architecture – Acti.EV (Advanced Connected Tech-Intelligent Electric Vehicle) and pronounced as ‘Active’, which will underpin future products from the TPEM portfolio.

The Acti.EV architecture is based on four pillars of Performance, Technology, Modularity, and Space Efficiency and consists of four layers:

Acti.VE architecture uses 400 volts. The power output for now is expected to be in the range of 80hp to 230hp, 

Acti.EV features an optimised battery pack design, with cells tested to advanced global standards – leading to 10% improvement in energy density. This battery pack design also offers multiple range options from 300km to around 600 kilometres. The architecture also allows for modularity in choosing the right drivetrain option for the appropriate product, between AWD, RWD, and FWD. The new EV architecture can support 7.2kW to 11kW on-board chargers for AC fast charging and DC fast charging up to 150kW – thereby adding around 100km range in just 10 minutes.

Acti.EV designed to achieve 5-star crash test rating; will protect the battery in side and pole impact tests, important for electrical safety. This, as per Tata Motors, done by using a high percentage of ultra high strength steel.  

The second layer of this architecture can house multiple body styles with a reinforced body structure capable of meeting future GNCAP / BNCAP safety protocols. Acti.EV maximises cabin space and storage with a flat floor without a transmission tunnel, and an added frunk, therefore allowing more space for occupants in the cabin. Its lower centre of gravity helps in improved driving dynamics and handling.

The 5G-enabled system will allow for over-the-air updates and cloud computing, with the digital cockpit experience powered by the Qualcomm Snapdragon processor and other compatible chipsets.

This is a future-ready scalable architecture with higher computing powers and ADAS Level 2 capabilities. Tata Motors states Acti.EV is ready for ADAS L2+ capabilities – ensuring higher standards of safety and navigation capabilities. Its 5G readiness allows for advanced network speeds with seamless connectivity. The architecture will also support Vehicle to Load (V2L) and Vehicle to Vehicle Charging (V2V) technology.

Acti-EV is based on future-ready scalable cloud architecture with OTA updates for software and other features.

The Acti.EV architecture is based on future-ready scalable cloud architecture that promises an enhanced user experience, with Arcade.ev, an in-car app suite. Furthermore, Acti.EV is loaded with cutting-edge solutions that not only promise superior connectivity but advanced over-the-air updates for software and other features. 

Starting with the Punch EV, the Acti.EV pltform will underpin a entire range of new Tata EVs and SUVs, including the upcoming Curvv EV, the new Sierra Ev and Harrier EV. 


Tata Motors’ new ‘pure EV’ electrical architecture will debut on the new Punch EV, which was also revealed today. The architecture will underpin a whole range of new Tata EVs and electric SUVs, including the upcoming Curvv EV, the new Sierra EV and the Harrier EV.

Likely to be the mainstay of the brand, it is expected to underpin all of the company’s current range in future, with more cars likely to be tagged on at a later stage as well. Acti-VE is not to be confused with Tata Motors’ earlier announcement of the Premium Pure EV architecture, shared with JLR (known as the EMA), which will be used to underpin more premium cars like the Tata Avinya. Tata Motors plans to have two pure electric vehicle architectures as it seeks to build a portfolio of 10 EVs in the coming years.

Anand Kulkarni, Chief Products Officer, Head of HV Programs and Customer Service, Tata Passenger Electric Mobility Ltd., said, “Acti.EV is a made-in-India advanced Pure EV architecture that promises to be a trendsetter in the country’s rapidly developing EV market. This architecture has been meticulously designed to enable class-leading efficiencies, maximising space, battery capacity and enhancing the overall driving experience. Acti.EV is a global ready, future-facing pure electric architecture that enables the implementation of software-oriented features, ensuring that our vehicles are not only technologically advanced but also future-proof.”

Punch EV, which looks like a scaled-down Nexon EV, will have two variants on offer – Standard and Long Range –  with 25kWh and 35kWh battery packs, respectively. Pricing estimated to be between Rs 10 lakh to Rs 13 lakh

The Punch EV, Tata Motors’ first new model for 2024, is the first model to use the Acti-EV architecture. The Punch EV is Tata’s fourth all-electric car after the Nexon SUV, Tigor sedan and Tiago hatchback, and is now its second electric SUV. Bookings for the new Punch EV are now open and can be made at Tata’s new EV-only outlets, select standard showrooms, and via the company’s online portal for an amount of Rs 21,000.
