The second phase of the BS6 emission regulations will go into effect on April 1, 2023.
The upcoming Real Driving Emissions (RDE) norms in India are expected to spell the end of some diesel-powered passenger vehicles. Previously, we reported that Skoda would discontinue production of the Superb and Octavia, and now, according to a new report, Hyundai may also discontinue production of the i20 Diesel.
The second phase of the BS6 emission regulations will go into effect on April 1, 2023. To meet the new standards, automakers would have to significantly upgrade their diesel engines. Some models are likely to be phased out due to the high costs involved.

The Hyundai i20 is powered by a 1.5-liter diesel engine that produces 99 BHP at 4,000 rpm and 240 Nm at 1,500-2,750 rpm. It is connected to a 6-speed manual transmission. The Venue and Kia Sonet both have the same 4-cylinder oil burner.
In the Verna, Creta, and Alcazar, Hyundai offers a 1.5-liter diesel engine with a variable-geometry turbo (VGT). According to reports, this engine will be upgraded with selective catalytic reduction (SCR) to meet the new standards.
