Tata EV Portfolio
Tata is an EV brand owned by Tata Motors and made in India. This model portfolio showcases the shift toward zero-emission mobility.
Vehicles are organized by model family. A model family is an OEM-defined product program sharing a common platform, architecture, and market positioning, from which multiple body styles, variants, and trims are derived.

Tata EV Technology
Platform: Dedicated EV, 400VE/E Architecture: Baseline
OTA Capability: Baseline
Battery Suppliers: LG Chem, Tata
Power Inverter Tech: IGBT-based
Platform = level of vehicle platform maturity or advancement, and its dominant system voltage.
Shared = ICE-derived | Dedicated = EV-native platform | SDV-Native = future-proof
E/E Architecture: degree of integration and maturity of the vehicle’s electronic/electric control systems (from Baseline legacy wiring to Advanced domain/zonal designs).
Baseline = Distributed ECUs | Modern = Domain-based | SDV-Native = Zonal-based with central compute
OTA Capability = scope of Over-The-Air updates supported — from Baseline basic infotainment to Advanced control and systems firmware.
Baseline = Infotainment/maps | Limited = Infotainment+ | Partial = Multiple systems | Advanced = Most systems | Full = Full-vehicle updateable
Battery Suppliers = primary traction battery suppliers across the model lineup.
Power Inverter Tech = power electronics technology used (silicon carbide SiC vs silicon), which affects efficiency and thermal performance.
IGBT = Conventional | SiC = High-efficiency | GaN = Next-generation, pilots
