"The EV transition means we aren't just building mechanical vehicles anymore; we are building rolling computers. When 80% of the baseline software is generic, trying to invent it alone wastes precious time." - Ranjani Padmanabhan, Technology Group Lead - Electric Powertrain - Royal Enfield

July 2026 : The definition of a vehicle has changed forever. Walk onto any modern automotive design floor, and you’ll quickly realize that the classic mechanical blueprint is only half the story. In the era of electric vehicles and Software-Defined Vehicles (SDVs), automotive development is a complex puzzle combining electronics manufacturing, circuit design, and massive layers of software.

With so many variables in play, a critical question arises: does one size fit all? Absolutely not. Every player in the ecosystem brings different strengths to the table. Some excel at mechanical architecture, while others have a distinct edge in advanced power electronics.

This reality took center stage at the Hindalco CXO Power Breakfast, a high-stakes roundtable held on the sidelines of the 4th Edition of the ACMA Automotive Smart Manufacturing Think Turf 2026, powered by Pro MFG Media and Knowledge Partner - CAAR & Supporting Partner - GARC.

Industry leaders gathered to dive into the theme: Reimagining Next Generation Mobility Platforms: Lightweighting, Smart Engineering & Sustainable Manufacturing for the EV Era.

Among the standout perspective-shifters was Ranjani Padmanabhan, Technology Group Lead for Electric Powertrain at Royal Enfield. She urged the industry to pivot away from hyper-isolated development and look toward a more unified, ecosystem-driven approach.

The traditional automotive mindset assumes that every company must build its proprietary technology from scratch to remain competitive. Padmanabhan shattered this myth by pointing out a massive hidden truth in modern vehicle engineering.

"Software-Defined Vehicles are coming up incredibly fast, but the reality is that roughly 80% of these solutions are generic," she explained. "What differentiates a brand is simply the remaining 20% - the customization for individual vehicle dynamics and brand experience."

Instead of forcing dozens of local companies to independently reinvent the same foundational code and electronics architecture, Padmanabhan suggests creating a shared, standardized baseline. By establishing a common technological foundation that all domestic OEMs can draw from, Indian manufacturers can skip the redundant groundwork and focus their capital entirely on customization.

This strategy isn't untested - it is the exact playbook China utilized over the last two decades to leapfrog global competition and achieve rapid EV scale. It is time for India to take a page from that book.

While building a shared technology baseline is a medium-term goal, Padmanabhan also highlighted immediate "quick wins" available to engineers right now.

In the race to maximize EV battery range, material lightweighting is priority number one. Instead of relying purely on expensive new metals, companies can turn to AI-driven digital twins to revolutionize structural design.

By running complex simulations, engineers can figure out how to merge multiple separate components into single, highly integrated structures. This physical consolidation cuts out unnecessary brackets, fasteners, and heavy interface joints - dropping vehicle weight instantly without compromising structural safety or driving dynamics.

For long-term innovation, Padmanabhan highlighted a glaring gap in how India approaches academic research. When analyzing research programs outside of India, university projects are typically funded to solve direct, practical manufacturing bottlenecks for the industry.

"When I worked on academic research abroad, we partnered directly with heavyweights like Cummins and Rolls-Royce on high-pressure injection principles," she recalled. "We built the prototypes and solved the core combustion issues inside the lab, handing it back to the corporations only when it was close to production readiness."

In India, that immediate industrial bridge is often missing. University graduation projects and internships are full of brilliant minds, but their findings rarely translate into street-ready vehicle components.

Royal Enfield has already begun breaking this cycle by feeding highly specific, practical problem statements directly into regional institute internships. When local companies actively guide university talent, give them a target, and allow academia to share in the intellectual property (IP), it creates a powerful, self-sustaining loop.

The EV transition is moving far too fast for fragmented efforts. By anchoring grassroots university talent to real corporate needs and establishing shared architectural baselines, India can build a formidable, self-reliant mobility ecosystem that doesn't just adapt to global disruption, but actively drives it.
