Tata Sierra EV

The cabin takes heavy inspiration from modern tech devices, hiding physical buttons and relying on large digital displays for most daily controls.

Cabin Layout & Quality

• The dashboard uses a layered, horizontal design.
• The centrepiece is a 12.3-inch touchscreen for media and navigation.
• The driver also gets a separate 10.25-inch digital display for speed and battery statistics.
• A touch-sensitive climate control panel now sits lower down on the console.
• The steering wheel features a four-spoke design.

Seating Comfort

Front Row

• The front seats are wide and offer excellent back support.
• The driver gets six-way power adjustments with memory settings to save a driving position.
• Both front seats are ventilated.

Second Row

• Because the roof does not slope downwards at the back, headroom here is massive.
• The flat floor means a middle passenger can sit comfortably.
• The large signature side windows provide a huge amount of natural light from the outside.

Features That Improve Daily Use

• The 12.3-inch touchscreen
• A panoramic sunroof
• A 12-speaker JBL sound system
• Vehicle-to-Load (V2L) technology

By offering two battery packs and multiple trims, Tata Motors creates a wide price bracket for the Sierra EV.

Tata has provided real-world C75 figures for the Sierra EV. Also, since the car supports 110-120 kW fast charging, it takes only 25 (63 kWh) to 26 minutes (75 kWh) for the car’s energy levels to go from 20 to 80 per cent. And the brand gives the car’s first owners a lifetime warranty for its batteries, or precisely, up to 15 years.

Bilal specifies,

"Ideally, a good figure to have at this point is between 430 and 450 kilometres in mixed driving."

The Tata Sierra EV has no independently tested safety rating yet. But the Acti.ev+ platform of the brand usually shows a lot of structural rigidity, and it’s also backed up by advanced electronic assistance.

Passive Safety & Crash Protection

• The skateboard architecture uses a high-strength steel cage.
• It protects both the passengers and the floor-mounted battery pack.
• Tata provides six airbags as standard equipment across all variants.
• ISOFIX child seat mounts are standard in the back row.

Active Safety & Stability Systems

• The top-tier Empowered A trim features a complete Level 2+ ADAS package.
• It offers 22 distinct functions.
• Two important features include automatic emergency braking and adaptive cruise control.
• A high-resolution 360-degree surround-view camera is also available.

The cabin’s technology uses a heavy multi-screen layout to manage the vehicle.

Infotainment & Interface

• The centre gets a 12.3-inch touchscreen.
• The front passenger gets their own dedicated 12.3-inch entertainment display.
• The driver looks at a crisp 10.25-inch digital instrument cluster.
• The top variant includes an Augmented Reality (AR) Head-Up Display.
• Wireless Apple CarPlay and Android Auto offer a lag-free connection.

Cabin Convenience & Practical Features

• The 12-speaker JBL sound system includes Dolby Atmos.
• The dual-zone automatic climate control is operated via a touch-sensitive panel.
• Vehicle-to-Load (V2L) and Vehicle-to-Vehicle (V2V) charging capabilities allow you to use the car’s battery to power camping equipment or charge another stranded electric vehicle.

The Sierra EV takes full advantage of its boxy shape to provide as much boot space as possible.

• You get 622 litres of storage, one of the largest in its segment.
• A 35 to 55-litre ‘frunk’ is available up front for storing charging cables and small items.
• The boot floor easily takes in large, bulky items when the rear seats are folded down.
• Tata maximised the vertical depth of the boot, allowing you to stack hard-shell suitcases.
• The tailgate is fully electric and can be opened automatically from the key fob.

The Sierra EV’s suspension manages the heavy battery weight without ruining ride comfort.

Bilal says,

"It holds a clean line and remains reassuringly stable at speed."

City Driving

• The steering feels very light at low speeds.
• It hides the sheer weight of the SUV well when parking.
• Over city roads, the Frequency Dependent Damping suspension absorbs harsh bumps well.
• The cabin remains completely isolated, preventing passengers from getting thrown around.

Highway Driving

• The Sierra EV excels as a high-speed cruiser.
• The 2,730 mm wheelbase and heavy battery pack keep the car planted.
• It ignores strong crosswinds and feels entirely stable on concrete expressways.
• Body lean is felt on fast corners, but the tall proportions are well-managed most of the time.

Tata splits the Sierra EV into five main trims: Pure, Pure S, Adventure, Empowered, and Empowered A.

The Essentials That You Don't Get

• A variant with a third row of seats
• Physical buttons and dials for the AC

For most buyers, the 63 RWD variant gets the job done when the priority is daily city driving. For an interstate traveller, upgrading to a larger battery makes sense.

Best for Strict Budgets: Pure 63 RWD

If you need a large, premium electric vehicle for short city commutes and school runs, the base Pure variant can handle such duties. The 63 kWh battery delivers over 440 km of real-world range, so expect a full week of driving without needing a mid-week charge.

Best for Highway Cruising: Adventure 75 RWD

This variant gets the massive 75 kWh battery, offering the maximum 510+ km of real-world range. It also adds crucial premium features like the 360-degree camera, the panoramic sunroof, and the JBL audio system, without demanding the heavy premium associated with the ADAS tech.

Best for Performance and Bad Roads: Empowered A 75 AWD

If you drive through heavy rain, snow, or muddy farm trails, you need the top variant. The dual-motor setup provides true all-wheel-drive grip, and the 504 Nm of torque delivers sports-car acceleration, dropping the 0-100 kmph time to 5.8 seconds.233
