A 108-year-old patent came roaring back to life on Founders' Day 2026 — and the man most moved by it was Mahindra Group chairman Anand Mahindra. Engineers at Mahindra Research Valley in Chennai did what no one had done since 1918: they read the original drawings filed by group co-founder J.C. Mahindra for a two-cycle, opposed-piston engine designed to run on crude oil, and they actually built it.

Anand Mahindra had shared the story of the patent six months ago, believing it was a historical footnote. The Chennai research team had other plans. Working as what Mahindra called a labour of love, they interpreted the century-old patent drawings, resolved the engineering gaps across more than a century of missing context, and unveiled a fully functional prototype on the company's Founders' Day — firing it up in front of the group.

The 1918 Patent That Started It All

J.C. Mahindra — Jagdish Chandra Mahindra — filed the patent in 1918, two decades before the company that bears his name was formally established. The engine design, a two-cycle opposed-piston format meant to run on crude oil, reflected the engineering curiosity of an era when India's industrial capacity was almost entirely colonial in character. That an Indian entrepreneur was filing engine patents that year is itself a striking historical fact.

Anand Mahindra recalled that his father and uncle described J.C. as a tinkerer — someone driven not by corporate mandate but by the compulsion to imagine and build. That word, deployed with obvious affection, threads the entire message together.

Mahindra Research Valley's Quiet Feat of Reverse Engineering

Mahindra Research Valley (MRV) in Chennai is the group's primary automotive and technology research hub. The engineers there did not restore an existing machine — they reconstructed one from drawings alone, bridging a gap of more than a century in materials science, manufacturing tolerances, and fuel standards. The prototype was unveiled and run on Founders' Day, a date chosen with clear symbolic intent: to present the founders' spirit as a living inheritance, not a framed portrait.

Mahindra wrote that he could not adequately express his gratitude to the team. The restraint in that phrase carries more weight than any superlative could.

The Tinkerer's Mandate

The chairman's closing lines were addressed directly to every engineer and innovator across the Mahindra Group. The call was unambiguous: May we never stop tinkering. May we never stop imagining, experimenting and building. It is the kind of internal rallying message that lands differently when it is anchored to a physical object — a running engine — rather than a slide deck.

For a conglomerate navigating electric vehicles, aerospace, and digital services simultaneously, invoking the spirit of a 1918 crude-oil engine is a deliberate act of institutional storytelling. The message is not 'look how far we've come.' It is: the instinct that started this was curiosity. Don't lose it.
