The company has modified the ICE Punch’s monocoque to increase cabin space, improve structural strength, and lower manufacturing tool requirements for its electric sub-compact SUV version.

Four years after launching the Nexon EV, derived from its internal combustion engine (ICE) model, Tata Motors has introduced the Punch EV using its new Gen-2 EV architecture named Acti.ev, unveiled on January 17. This new model retains a similar exterior design to its ICE version but features extensive under-the-hood changes, adopting a platform that provides genuine EV performance.

Significant modifications include a redesigned monocoque to enhance cabin space and structural integrity, notably by removing the rear hump for exhaust systems, resulting in a flat cabin floor for additional space and a higher ground clearance of 190mm with an orthogonal battery pack beneath. These changes do not affect the boot capacity, maintaining it at 366 litres.

Despite outward similarities, the Punch EV represents a departure from the ICE version, with a complete reengineering for electric power, emphasizing the Acti.ev platform’s role as a dedicated EV architecture. This platform accommodates various drivetrain layouts and has undergone adjustments for crash safety and reduced manufacturing complexity, leading to a lighter, more rigid structure capable of meeting high safety standards.

The Punch EV features an LFP battery with a unique orthogonal shape for efficient packaging, offering two battery options with ranges of 315km and 421km. The architecture’s flexibility allows for different battery chemistries, future-proofing Tata’s EV lineup. Charging solutions include standard and fast charging options, with significant energy recuperation through regenerative braking.

Driving the Punch EV reveals balanced handling and stability, with a design that effectively manages body roll and absorbs road imperfections despite a heavier kerb weight than the ICE Punch. Adjusting suspension components ensures a comfortable ride, demonstrating Tata’s comprehensive approach to evolving its EV offerings beyond simple ICE conversions, showcasing design, safety, and performance innovation.
