Since the cost of upgradation to comply with the stringent BS6 emission norms is relatively higher in diesel engines as compared to petrol powertrains, some manufacturers have decided to pull the plug on diesel engines entirely. This includes the country’s biggest car manufacturer, Maruti Suzuki.
The Japanese company believes that the current difference of around Rs 1 lakh between a petrol and a diesel variant of the same car could go up to Rs 2 lakh once the BS6 norms come into action, which will make the diesel powertrain of budget-friendly cars unfavorable.
However, there are a few manufacturers who have decided to discontinue their petrol powertrains as well, which includes –
Ford is planning to discontinue the 1.0-liter EcoBoost three-cylinder turbocharged petrol engine offered on the sporty ‘S’ variant. The said engine is good for 125PS of power and 170Nm torque but has low demand since the 1.5-liter four-cylinder naturally aspirated petrol engine has a similar power output now and is more affordable.
Volkswagen will likely be replacing the 1.2-liter TSI engine currently on offer with the Polo GT with a new BS6-compliant 1.0-liter three-cylinder petrol unit. The current engine produces 105PS of max power and 175Nm peak torque and comes mated to a 7-speed DSG.
Skoda’s 1.8-litre TSI engine which powers the current-gen Octavia makes 180PS power and 250Nm torque. Reportedly, Skoda is planning to discontinue the current-gen Octavia post the BS6 deadline of April 1, 2020.
The Czech carmaker will be launching the new-gen Octavia late next year, with a 1.5-liter four-cylinder TSI Evo engine, which powers many Volkswagen cars internationally.
The Baleno’s sportier avatar, Baleno RS is offered with a 1.0-liter three-cylinder turbo-petrol engine that puts out 102 PS/150Nm. However, the car could never perform as good as the company would have liked, and upgrading its engine to comply with the BS6 norms doesn’t make any sense.
Hyundai currently offers its 1.6-liter VTVT petrol engine with the Creta and the Verna, which is good for 123 PS. However, in order to save costs, the Korean carmaker will be borrowing the Kia Seltos’ 1.5-liter petrol powertrain for the next-gen Creta and the Verna facelift, both of which are set to be launched next year.
The power figures of Kia’s BS6-compliant 1.5-liter engine are rated at 115PS/144Nm.
