The Tata Sierra will come with three engine options – petrol, diesel and electric. As per latest media reports, the ICE-powered version might be introduced first (possibly in November 2025), followed by the electric Sierra in January 2026. The petrol model will initially come with Tata’s all-new 1.5L naturally aspirated engine, and the new 1.5L turbocharged petrol engine will come later.
The diesel version is likely to feature Harrier-sourced 2.0L Kryotec engine, producing a maximum power of 170bhp and 350Nm of torque. The Sierra EV is expected to borrow powertrains from the newly-launched Harrier EV. The Tata Sierra SUV lineup will come with both manual and automatic gearbox choices. The higher trims are expected to be offered exclusively with the AWD (all-wheel drive) system.
