The engine updation procedure would be expensive, especially for diesel vehicles and why as many as 27 automobiles and SUVs are anticipated to be terminated in the Indian market.

The Real Driving Emissions (RDE) rules that will take effect in India in April 2023 would result in the demise of various automobiles and SUVs. This new set of emission laws will assess pollutants such as NOx generated from a car in real-world driving scenarios, taking into account the frequent changes in speed, acceleration and deceleration.

 When the new standards go into effect, automakers will have to modify their engines to reduce pollution. Because engine upgrades would be costly, particularly for diesel vehicles, as many as 27 cars and SUVs are expected to be discontinued in the Indian market.

Vehicles will be required to have on-board self-diagnostic equipment to detect real-time driving emission levels under RDE standards. The gadget will keep track of crucial components like catalytic converters and oxygen sensors to ensure they fulfil emission requirements. 

Carmakers will also need to modify car semiconductors to read crankshaft positions, throttle, and engine temperature, among other things. The vehicles and SUVs will also need to have programmable fuel injectors to manage the amount of gasoline burned.

Because all diesel engines will have to switch to the more expensive’selective catalytic reduction’ (SCR) pollution control technology, diesel automobile prices will skyrocket. Rising prices will undoubtedly force automakers to retire models or variations that do not justify the increased production and marketing costs.

Honda will discontinue five models: the City 4th generation, City 5th generation (diesel), Amaze (diesel), Jazz, and WR-V. Mahindra will discontinue manufacture of the Marrazzo, Alturas G4, and KUV100. Hyundai and Skoda will each phase out two models. 

While Hyundai Car will discontinue production of the i20 and Verna diesel models, Skoda will discontinue production of the Octavia and Superb.

Tata Altroz (diesel), Renault Kwid 800, Nissan Kicks, and Maruti Suzuki Alto 800 will be among the vehicles available.

As is obvious, tiny diesel automobiles would suffer the most since the expense of updating smaller engines would be prohibitively expensive in comparison to the price of the car itself. Spending that much money becomes unsustainable in light of the fact that demand for diesel vehicles in the hatchback and sedan classes has decreased significantly in recent years.

 Petrol vehicles with the ability to generate revenue equivalent to the cost of the enhancements will also be phased out.
