According to the official announcement, the new Tata Sierra will feature a 1.5-litre turbo-petrol engine and a 1.5-litre diesel unit, both tuned to balance performance with efficiency.

Powertrain and Performance Details

Here’s what’s confirmed so far about the Tata Sierra engine lineup:

  • Output: 170 PS
  • Torque: 280 Nm
  • Transmission: 6-speed manual / 7-speed DCT (dual-clutch automatic)
