A single line on a graph determines the following iteration of India’s fuel efficiency rules, which was first introduced to the manufacturers in 2017 to reduce the emissions of the vehicle. (AI-generated image) Summary policymakers and car manufacturers discuss the slope of a single line on a map that will form India’s fuel economy norms from 2027. At stake: The future of small cars, SUVs and trucks. Policymakers in New -Delhi and Car manufacturers across the country are currently focused on the same map – a Cartesian chart containing a single rule. It’s no simple line. The slope will determine the production strategy for India’s vehicle manufacturers for half a decade. The graph determines the following iteration of India’s fuel efficiency rules, which was first introduced in 2017 to push manufacturers to reduce vehicle emissions. These rules, called the framework of corporate average fuel efficiency (CAFE) for cars and guidelines for trucks and constant speed fuel consumption (CSFC) for trucks, are tightened every five years. Discussions continue for the third iteration of the cafe rules and the second iteration of CSFC, to be implemented in April 2027. Mint explains the math behind the slopes of fuel efficiency, lights and heavy vehicles, fuel efficiency testing, and statistics used worldwide to decarbonize the roads. When did fuel efficiency frameworks arise? The US was the first country to suggest fuel efficiency regulations in 1975 due to the Arab oil embargo a few years earlier and the high dependence on oil imports. This has instructed vehicles manufacturers to make more high mileage vehicles to reduce gasoline consumed by the transport sector. India introduced broad fuel efficiency guidelines in the early 1990s, but the first issue of the cafe regulations was notified in 2014. As Cafe 3 discussions take shape, Transport and highways, Nitin Gadkari, repeatedly asked to reduce India’s high fuel import account of approximately £ 22 trillion and promote sustainable mobility. How are fuel efficiency regulations determined? Different countries calculate fuel efficiency differently. In India, carbon dioxide released per kilometer is the most important metric, while in the US it is the distance per gallon fuel, and in China it is the fuel consumed for every 100 km. How is it shown on a graph to determine fuel efficiency? Consider an ordinary graph with y and x -axis. Take the vehicle weight on the horizontal y-axis, and one of the above statistics on the vertical x-axis. Smaller vehicles are lighter and more fuel efficient, while larger vehicles need more fuel to drive and heavier. Depending on the metric used, it would create a sloping line on the graph. For example, the US uses miles as a metric. So the line would slide downward to heavier vehicles. For Indian and Chinese statistics, the line will slide upwards to heavier vehicles. This is where policymakers enter. Their task is to determine the slope of fuel efficiency limits. Will it follow the curvature and slope of the industry’s fuel efficiency matrix? Will this allow some rest for all kinds of vehicles? Or will it be strict? How does it play out in India? The Hullbaloo on Cafe 3 discussions over the past few months has been on the benefits for small cars, usually those under 4 meters. On one side of this debate is Maruti Suzuki India Ltd, as sales of small cars such as Swift, Alto and Wagon R are responsible for a significant part of its topline. On the other hand, car manufacturers such as Mahindra and Mahindra Ltd and Hyundai car India Ltd selling large diesel cars, but have also invested a lot in zero emission technology such as electric vehicles with batteries. This is where policy instruments such as CAFE and CSFC can use production strategies based on the slope in their fuel efficiency graph. The US and China have carving for extremely light and heavy vehicles. This means that the line that draws policy makers for fuel efficiency heads goes flat in extremes, but has a slope in the middle. If car manufacturers make cars lighter than a specific weight, the fuel efficiency restriction remains the same. If their vehicles manufacture heavier than a specific limit, their shell remains constant. If a company manufactures heavy diesel-guzzing cars to allow for premium sports utility vehicles, it must ensure that the fuel efficiency of the vehicle stays within the limit, no matter how heavy the vehicle is. But smaller cars get benefits. No matter how much smaller a vehicle gets, fuel efficiency heads are not getting tighter. India’s cafe framework uses on average vehicle weights to determine the fuel emissions cap. This is the point on the X-axis that will determine the fuel outlet cap line on the graph and its slope. In terms of Cafe 2 rules, the weight is 1.145 kg. This will be revised to 1,170 kg in the proposed Cafe 3 frame, which would affect the changes in fuel efficiency kicks. For cafe 3, the government suggested that the fuel efficiency shell reduced from 113 grams of CO2 per kilometer to 91.7 and further reduced to 70 in cafe 4, which took place for implementation in 2032. What about trucks? India’s fuel efficiency rules for trucks are not without controversy. Vehicle makers wanted trucks that weighed less than 3.500 kg to be exempt from CSFC rules. The government rejected this claim. Truck makers now demand that a homemade simulator instrument called Bharat vecto be used to calculate fuel efficiency. But the instrument does not exist yet. What role electric vehicles play in all this? India’s fuel efficiency rules for cars and trucks include cars for cleaner technology, called Super Credits. For example, every electric car sold by a car manufacturer is sold as three units, while a hydrogen fuel cell vehicle is considered four, as vehicles running on these power substances do not emit carbon dioxide. Vehicles that radiate less CO2 than a petrol or diesel vehicle also receive benefits, with the proposal to count each biofuel vehicle as 0.95 units sold. Vehicles with smaller technological decorations to increase fuel efficiency, such as regenerative brakes, are counted as 0.98 units. What is the constant debate on E20 petrol? India has recently made it mandatory for gasoline cars to be mixed on fuel with 20% ethanol to reduce CO2 output as well as the country’s oil imports. Motor owners complain that E20 petrol (gasoline mixed with 20% ethanol) does the fuel miles damage and can result in long-term engines wear, which indirectly contributes to higher pollution levels. Some car manufacturers said E20 petrol slightly affects the efficiency of vehicles, mainly older vehicles that were not designed for E20 fuel. However, the government remains steadfast in its support for the mixing of biofuels. What other policy instruments are an integral part of roads? The automotive industry continues to relax the rules for fuel efficiency, as investment in cleaner and more sustainable motor technologies is expensive and can increase vehicle prices, a huge concern in the pricing market in India. But fuel efficiency regulations do not work in a silo. Other policy types such as CAPs on fuel emissions (Bharat stage regulations); Incentives for manufacturers to produce cleaner vehicles, such as the production-linked incentive scheme for the car sector (pli-auto); Incentives that encourage customers to buy electric vehicles, such as the PM e-drive scheme (PM Electric Drive Revolution in innovative vehicle improvement); And the development of the necessary infrastructure also helps decarbonize roads.
