    Tata RDE engines
    Listen to this Article

    Tata Motors has announced that its entire engine line-up now abides by the Bharat Stage 6 Phase-II norms. With this, all petrol engines from Tata are now RDE (real driving emissions) and E20 (20 percent ethanol and petrol blend) compliant, while the diesel engines are now RDE compliant. This comes ahead of the new, stricter emission norms kicking in from April 1, 2023.

    1. Punch, Altroz get engine start/ stop 
    2. Nexon diesel engine retuned for better performance
    3. Tiago, Tigor get TPMS 

    Tata Motors BS6 Phase II engines: what’s new

    Along with making its engines RDE and E20 compliant, Tata has also tuned them for better efficiency, refinement and driveability. These engines will now be cleaner as they are tested for emissions in more stringent real-world conditions, apart from being tested in a laboratory environment on the MIDC (Modified Indian Driving Cycle). Furthermore, to be E20 compliant, these engines will have a few modifications to the fuel systems, engine calibration and rubber hoses to handle the more corrosive nature of ethanol. E20 fuel will start rolling out in a phased manner from April 2023 onwards.

    Tata believes there is still plenty of demand for diesel and hence, the 1.5 diesel engine will continue in the Altroz and Nexon. The Revotorq diesel engine in the latter has also been revamped to deliver better performance. However, Tata didn’t mention if this retuned engine develops more power than before. Furthermore, it says the enhancements also improve the NVH (noise, vibration and harshness) levels.

    However, the 2.0 Multijet diesel – sourced from Stellantis – in the Harrier and Safari will likely have already achieved RDE compliance during it's BS6 Phase I upgrade.

    Tata Punch, Altroz, Tiago, Tigor get new features

    The Altroz and Punch now also get engine start/stop functionality that will enable them to improve their fuel efficiency. This will be available across all variants of Tata’s premium hatchback and sub-compact SUV. According to Tata, the low-end driveability of the two models has also been enhanced and they now have smoother power delivery in lower gears. 

    Tata has also added tyre pressure monitoring system (TPMS) in the Tiago hatchback and Tigor compact sedan.

    However, the biggest update to the entire product portfolio is the standard warranty. Earlier, the carmaker offered a 2 year/75,000km warranty as standard, which has now been increased to 3 year/1 lakh km as standard.
