The new emission norms, which are part of phase 2 of the BS6 emission norms, require vehicles to have an onboard self-diagnostics device to monitor pollutants such as NOx emitted from a car in real-world driving conditions.

The new norms require carmakers to update the existing technology in engines to further reduce emissions. Updating the existing technology, especially in diesel engines, will prove expensive for car makers, who instead will prefer phasing out the models built on old technology. For example, models such as Honda City and Hyundai i20 diesel have a smaller capacity oil burner, which is expensive to update to match the new norms. Such smaller capacity diesel engines use cost-effective LNT (Lean NOx Trap) technology to comply with the current rules; however the same will need to be replaced with more expensive Selective Catalytic Reduction (SCR) tech to be road-ready once the new norms come into effect.

Deterred by reduced demand for diesel hatchbacks and sedans and the increased cost of deploying the SCR system, carmakers have decided to instead phase out the vehicles.

Other than RDE norms, car makers will also shelf models that have reached the end of their life cycle. These include Honda WR-V and Jazz. Some other models on the way out are the ones which failed to enthuse customers and sell enough models. These are Mahindra KUV100 and Marazzo.
