In a move that has caught the industry off guard, Tata Motors has completely reshuffled the deck for its flagship electric SUV Coupe. Say goodbye to the 45kWh battery and hello to the Series.X.

At AutoCritic, we usually see manufacturers add minor trims to keep things fresh. But Tata just went “All-In.” They’ve discontinued the smaller battery pack entirely and dropped the entry price for the massive 55kWh unit to a staggering ₹16.99 lakh. This isn’t just a trim update; it’s a strategic takeover.

What exactly is the Series.X?

The Series X is Tata’s new simplified lineup for the Curvv EV. By focusing solely on the 55kWh battery pack, Tata is addressing the number one concern for EV buyers: Range Anxiety.

Every Curvv EV now coming off the line under the Series.X badge features the higher-spec 167hp motor and a massive 502km (MIDC) range. They’ve also introduced a striking new Nitro Crimson exterior shade that makes the coupe silhouette pop like never before.

The Lineup: Accomplished X vs. Empowered X

Tata has streamlined the variants into two main pillars (plus the Dark Edition). Here is how they stack up:

1. Curvv EV Accomplished X (₹16.99 Lakh)

Don’t let the “base” tag fool you. This is the new value king of the Indian EV market.

• Tech: Dual 10.25-inch displays (Infotainment + Digital Cluster).
• Comfort: Ventilated front seats and leatherette upholstery.
• Convenience: 360-degree camera with Blind Spot Monitor and a Panoramic Sunroof.
• The Verdict: For most buyers, this is all the car you’ll ever need.

2. Curvv EV Empowered X (₹19.19 Lakh)

If you want the full “AutoCritic” experience, this is where the luxury kicks in.

• Audio: A massive 12.3-inch touchscreen paired with a 9-speaker JBL system (including a subwoofer).
• Safety: Level 2 ADAS with 20 autonomous functions.
• Utility: V2L (Vehicle-to-Load) and V2V (Vehicle-to-Vehicle) charging support.
• Extras: 6-way powered driver seat and 18-inch aero-optimised wheels.

The “Lifetime” Warranty: A Game Changer

One of the most underrated parts of the Series.X announcement is the Lifetime Warranty on the battery pack (valid for 15 years from registration). For those worried about long-term battery degradation or resale value, Tata just handed you a massive safety net. It shows their confidence in the new activa.ev platform.

The AutoCritic Take: Why the 45kWh had to go

The 45kWh battery was always in a weird spot—too close to the Nexon EV Long Range but not quite hitting the “big SUV” numbers people wanted from the Curvv. By killing it off and pricing the 55kWh Accomplished X at ₹16.99 lakh, Tata has made the MG ZS EV’s life very difficult.

Is there a catch? The only downside we see is for the early adopters who bought the 45kWh version—their resale value just took a hit. But for the new buyer? This is arguably the best value-for-money EV in India right now.
