Tata Sierra EV interior leaked via design patent

The Tata Sierra EV and ICE models are two of the most hotly anticipated new cars launching in India this year. The company had showcased the Sierra EV in near-production guise at the Auto Expo 2023, but some details were still concept-like, especially on the inside. Now, a leaked design patent image gives us a first glimpse at the production-spec Tata Sierra EV interior. Let’s take a closer look.

3. Sierra EV launch is expected by 2025-end after the ICE version’s

Tata Sierra EV interior design leaked

Remains true to the concept

The first look at the Tata Sierra EV interior reveals that the production-spec model will indeed remain largely unchanged from the concept. The dashboard is dominated by a large central touchscreen (likely 12-inch) connected to the digital instrument cluster binnacle. Below the touchscreen are the central AC vents that appear a lot more prominent than they were in the concept, and the side AC vents are neatly integrated within horizontal lines running across the dashboard. The familiar 4-spoke steering wheel has also been retained.

Expected with unique accessories for personalisation

A lot of design cues have been retained from the near-production model's interior. 

The dashboard has a nice stepped effect that swoops down, and there’s also a centrally mounted speaker, which has been retained from the concept. However, the moss inserts from the concept do not seem to have materialised into production, but Martin Uhlarik, head of design at Tata Motors, previously told us that the company can offer it as an accessory should buyers want to customise the interior. This could also include options like mini flower vases for the door pads, fold-out tray tables and ambient lamp shades. Apart from a regular bench-type rear seat, the Sierra EV is also expected to come in a 4-seat lounge configuration with an ottoman function for the rear seats.

A lounge-style interior in 4-seat configuration is expected on the Sierra EV.

As for some of the switchgear, we expect the Sierra EV to borrow the touch-based HVAC panel and drive selector lever from the Curvv EV. The centre console will likely retain the floating design with additional storage spaces below it, as was seen on the concept.

Different interior design compared to ICE-powered Sierra

Interestingly, the Sierra EV’s dashboard will be different from that of the ICE-powered Sierra, which was showcased this year at the Auto Expo with a triple-screen layout spanning the dashboard’s width. This is pretty unusual for ICE and EV counterparts – observable in Tata’s line-up – but it should help differentiate the two products well.

Tata Sierra EV technical details, launch timeline

Unfortunately, technical details of the Sierra EV are currently scarce, but it is expected to share Tata’s acti.ev architecture with the Curvv EV. The SUV can be expected to be positioned slightly above the Curvv EV and below the upcoming Harrier EV. And unlike the Harrier EV, which will have AWD variants, the Sierra EV will have a front-wheel-drive setup. Its ex-showroom prices are expected to range between Rs 20 lakh and Rs 25 lakh. 

The Sierra EV is expected to launch by the end of 2025 after the ICE-powered Sierra goes on sale. It will compete with the likes of the Mahindra BE 6, Hyundai Creta Electric and upcoming Maruti e Vitara in the growing segment of midsize electric SUVs.
