The Sierra EV‘s cabin carries over much of the ICE Sierra’s layout, but with a dual-tone upholstery scheme and a genuinely generous features list that pushes it slightly upmarket of its petrol sibling. Here’s a detailed walkthrough of what you actually get inside, from the dashboard tech down to the small storage details that matter more in daily use than they do on a spec sheet.
The Triple-Screen Dashboard
The centrepiece of the Sierra EV’s cabin is its three-screen layout: a 12.3-inch touchscreen infotainment display for the driver and central controls, a separate 12.3-inch co-passenger entertainment screen, and a 10.25-inch digital driver’s display ahead of the steering wheel. The co-passenger screen is a genuinely distinctive addition in this price bracket, letting the front passenger control entertainment, navigation, or media independently without needing to reach across to the central touchscreen or disturb the driver’s display.
This layout does mean a lot of visual information competing for attention on a single dashboard, and buyers coming from simpler single-screen setups may want to spend time with the interface at a dealership to judge how intuitive the menu structure feels before committing, since screen count alone doesn’t guarantee ease of use.
Seating Comfort and Adjustability
Both front seats on the Sierra EV are ventilated, a genuinely welcome feature during Indian summers, and get 6-way power adjustment with a memory function on the driver’s seat, useful for households where more than one person regularly drives the car and wants their preferred position recalled automatically. The front passenger seat additionally gets a Boss mode, letting the driver adjust the passenger seat position remotely from the driver’s side, handy when you’re chauffeuring someone in the back seat and want to give them more legroom by moving the front passenger seat forward.

Rear passengers get their own dedicated AC vents, USB Type-C charging ports, manual sunshades, and a centre armrest. The combination of dedicated rear climate control and manual sunshades is a practical, if modest, comfort touch that matters more on long drives through Indian summer heat than it might initially seem on a feature list.
Climate Control
The Sierra EV runs dual-zone climate control, letting the driver and front passenger set independent temperatures. The control panel itself is touch-sensitive with a gloss-black finish, which looks sleek in showroom lighting but is worth testing in person before you buy: touch-only panels are generally harder to operate by feel while driving than physical buttons or a rotary dial, and the gloss finish tends to show fingerprints and smudges quickly with regular use. This is a genuine, if minor, everyday usability trade-off for the sleeker aesthetic.
An in-cabin air purifier is also included, relevant given air quality concerns in several major Indian cities during winter months, working alongside the climate system to keep cabin air genuinely cleaner during long commutes through heavy traffic.
Sunroof and Overhead Features
Tata claims the Sierra EV’s panoramic sunroof is the largest in its segment, a genuinely significant feature for buyers who value natural light and an open-cabin feel, particularly for rear passengers who often don’t get direct access to a sunroof control on vehicles with smaller units.
Head-Up Display
The Sierra EV includes a head-up display that projects key information, speed, navigation prompts, and ADAS status, directly into the driver’s line of sight on the windshield. This reduces how often the driver needs to glance down at the instrument cluster, a genuine, if modest, safety and convenience benefit that compounds over thousands of kilometres of driving.
Sound System
A 12-speaker JBL sound system with Dolby Atmos support handles audio, a genuinely premium setup for this price bracket that should appeal to buyers who spend meaningful time listening to music or podcasts during commutes. Audio quality has been specifically highlighted as a strength in early ownership impressions of the Sierra EV, alongside ride comfort and build quality.
Storage and Practicality Inside the Cabin
Beyond the boot and frunk covered elsewhere, the cabin itself includes a wireless phone charger, an NFC card key for keyless entry and start, and the usual assortment of cupholders and door pockets expected in this segment.The rear seats also feature a 60:40 split-folding, reclining design in higher trims, adding flexibility for carrying longer items alongside passengers without needing to fold the entire rear bench flat.
Ambient Lighting and Cabin Atmosphere
Higher variants of the Sierra EV include ambient lighting, contributing to the cabin’s more premium feel after dark, a feature that’s become increasingly common across this price bracket but still adds genuine visual appeal for buyers who value cabin atmosphere alongside pure functionality.
Connectivity
Wireless Android Auto and Apple CarPlay are available, letting most owners connect their phones without needing a cable for navigation, calls, or media, a genuinely important convenience feature that’s now expected rather than a differentiator, but still worth confirming is present given how frustrating a wired-only setup can be in daily use.
What Feels Genuinely Premium vs What’s Standard Segment Fare
It’s worth separating what actually distinguishes the Sierra EV’s cabin from rivals versus what’s now standard across this price bracket. The triple-screen layout with a dedicated co-passenger display, the claimed segment-largest panoramic sunroof, and the Boss mode passenger seat control are genuine differentiators that most rivals in this price range don’t match. Ventilated seats, wireless charging, a head-up display, and dual-zone climate control are increasingly common across the segment rather than unique Sierra EV strengths, though their presence still matters for overall cabin quality even if they’re not standout features specifically.
The one recurring criticism worth flagging honestly: the touch-sensitive climate panel’s everyday usability. It’s a small detail relative to everything else the cabin gets right, but it’s the kind of thing that’s easy to overlook in a showroom test sit and genuinely notice a few months into daily ownership.
