Built on New ARGOS Architecture
The 2025 Sierra is based on Tata’s newly developed ARGOS architecture, which stands for All-Terrain Ready, Omni-Energy, and Geometry Scalable. This modular platform can support both ICE and electric vehicles.
It also supports all-wheel drive, making the Sierra suitable for off-road use. Tata Motors claims the architecture is built for durability and rugged driving conditions.
Next-Gen Electrical System with 5G Support
A major feature of the new Sierra is the tidal 2.0 electrical architecture, which is the first Ethernet-based system in an ICE vehicle in India. It supports data transfer speeds of up to 1 Gbps. This platform also introduces 5G connectivity, offering faster vehicle-to-cloud communication and enabling seamless over-the-air updates.
The setup includes centralised computing, integrated domain controllers, and a CAN-FD network for faster ECU communication. Tata also claims the SUV has end-to-end cybersecurity systems and cloud-backup storage for better software performance.
Advanced Safety Features
The Tata Sierra comes equipped with more than 20 safety features as part of its Level-2 ADAS suite. The SUV includes:
- 6 airbags (standard)
- Seatbelt anchor pre-tensioners
- ISOFIX mounts
- 3-point seatbelts for all seats
Tata Motors also states that the Sierra’s body structure is engineered to deliver strong crash performance in both frontal and side-impact situations. The launch of the Tata Sierra marks an important moment for Tata Motors as it expands its SUV lineup.
