Four decades ago, India’s two-wheeler market became a battlefield for four Japanese automotive giants, each seeking to capture the mobility of a nascent middle class.

While Suzuki, Yamaha, and Kawasaki placed their bets on the youthful allure of performance and the raw power of two-stroke engines, Hero Honda of the Munjal Group chose a quieter, more utilitarian path.

In 1985, Hero launched the CD 100, a modest motorcycle equipped with a four-stroke engine.

What it lacked in speed, it made up for in an engineering metric that matters more than horsepower to the subcontinental consumer: thrift.

Backed by a brilliantly bold advertising campaign — headlined by the iconic mantra, "Fill it, Shut it, Forget it" — the bike promised an unprecedented 80 kilometers per liter.

The phrase quickly permeated the national lexicon, used millions of times even in entirely non-motorcycling contexts.

As automotive journalist Srinivas Krishnan, former Editor of Business Standard Motoring and columnist with AutoX, pointed out to me, Hero deliberately went for pure efficiency at a time when its rivals were chasing youthfulness and power — traits that fuel-thirsty two-stroke engines excelled at delivering.

The four-stroke CD 100 was subdued, but it was highly economical.

The Return Of The Mileage Metric

Today, history is repeating itself and macroeconomic shocks are forcing drivers to prioritise efficiency.

Three whole months after the onset of the war in West Asia, with fuel prices having risen and poised to climb further, the focus is back on fuel economy.

The difference today is that innovation is no longer focused on squeezing an extra kilometer out of the internal combustion engine; instead, the market is leaning heavily into electric, hybrid or alternative fuels.

For the last few years, electric vehicles (EVs) in India have grown rapidly but lagged behind Western and Chinese adoption curves.

The last few months, however, have sharply altered consumer perceptions.

The shift is visible on the ground.

Just last week, my driver told me that at least three new electric cars of varying shapes and sizes had been purchased within our sprawling, multi-tower residential complex in Mumbai.

This anecdotal surge appears to be backed up by corporate data.

Shailesh Chandra, Managing Director of Tata Motors Passenger Vehicles told Autocar Professional magazine last week that while EVs historically accounted for roughly 15% to 16% of the company's current sales mix, forward bookings have suddenly climbed to nearly 23%.

This suggests that demand is running significantly ahead of available production capacity.

According to Chandra, the recent spike in fuel prices has dramatically accelerated the consumer migration toward alternative powertrains.

"In the last two months, the jump has been two to two-and-a-half times of what it used to be," he noted, adding, "In the last 15 days, things have changed completely. It is an even sharper growth."

To address this wave of demand, Tata Motors is actively working to raise EV production by around 50%, aiming to scale monthly output from roughly 10,000 units to 15,000 units over the next few months.

Autocar Professional reports that other carmakers with growing EV portfolios, such as JSW MG Motor and Mahindra & Mahindra, are experiencing a similar demand surge.

The Power Of Price Signals

This rapid consumer migration underscores a fundamental truth about the Indian market: the extreme value-consciousness of its buyers.

Electric vehicles are proving to be a boon for a country searching for affordable mobility and their success has come despite relatively weak public charging infrastructure.

When economic incentives align, Indian consumers evidently bypass infrastructural inconveniences.

As Krishnan quipped, whether someone is buying a top-end luxury Mercedes-Benz or a simple two-wheeler, the unifying question remains exactly the same: "Kitna deti hai?" — How much mileage does it give?

This shift also offers a profound lesson in the efficacy of raw price signals.

India delayed raising retail prices for petrol and diesel by at least two months.

Once those higher prices finally hit the pumps, they acted as an immediate, unvarnished incentive for customers to shift or consider moving to more eco-friendly fuels, including electric, a transition that obviously bodes well for the wider economy.

It may even force internal combustion engine manufacturers to look for new efficiencies, though it remains unclear how much more mileage can realistically be extracted from traditional fossil-fuel setups.

Crises also have a remarkable track record of sweeping away institutional inertia.

High fuel prices will undoubtedly accelerate further innovation, accelerating the domestic supply chains for batteries and hybrid tech.

When a crisis alters consumer behavior this sharply, it forces capital to allocate more efficiently.

Forty years after its debut, Hero still sells the CD 100 platform as the improved Hero Splendor, operating on almost identical engineering specifications.

There has been no turning back from the point the four-stroke engine transformed India from a nation of casual commuters into a global two-wheeler manufacturing powerhouse.

Today, the price signals sent by expensive fossil fuels are doing something similar for the EV ecosystem.

For India's economy, nudging drivers to "fill it, shut it, and forget it" with an electrical cord rather than a fuel pump isn't just an environmental victory—it is a renewed textbook example of capitalist adaptation at its finest.
