Tata Sierra mid trim vs Tata Curvv top trim: Which offers more value?

The Tata Sierra and Curvv are both midsize SUVs that are positioned quite differently in Tata’s line-up. While the Curvv is a coupe-SUV built on the ATLAS platform, a modified version of the Nexon’s X1 platform, the Sierra has a traditional SUV look and uses a new ARGOS platform, which sits above ATLAS. We pit the mid-level Adventure+ trim of the Sierra against the top Accomplished+ A trim of the Curvv – since their prices overlap – and help you decide which one offers better value.

Tata Sierra mid trim vs Tata Curvv top trim: Specifications 

Curvv’s top trim skips the naturally aspirated petrol engine.

While Curvv offers two engine options, the Sierra gets three. Starting with what’s common, both get Hyperion turbo-petrol engines, but the Sierra’s unit delivers substantially higher power and torque figures thanks to higher displacement and comes paired only with a 6-speed torque-converter automatic; the Curvv offers a choice of 6-speed MT or a 7-speed DCT. Their diesel engines are the same 1.5-litre units, available in 6-speed MT or a 6-speed AT (Sierra)/7-speed DCT (Curvv) guise. The Sierra is also available with a 1.5-litre naturally aspirated petrol mill with a 6-speed MT.

Tata Sierra mid trim vs Tata Curvv top trim: Exterior 

Both are evenly matched when it comes to exterior features.

On the outside, both models offer similar features, but the Sierra Adventure+ with the naturally aspirated engine is also sold with 17-inch alloys, which will likely aid ride quality. While LED light setups are present on both, the Curvv’s unit gets welcome and goodbye animations. Also, the Curvv’s top trim comes with monotone and dual-tone paint options, while the Sierra only gets the former.

While Curvv gets more feel-good features, Sierra offers more convenience features.

Tata Sierra mid trim vs Tata Curvv top trim: Safety 

Sierra Adventure+ misses out on Level 2 ADAS.

Tata has equipped both the Sierra and Curvv with six airbags, ABS and EBD, ESC, hill-start assist, hill-descent control, a 360-degree camera and a blind-view monitor. However, the Curvv also includes a Level 2 ADAS suite and an auto-dimming interior rearview mirror (IRVM).  

Tata Sierra mid trim vs Tata Curvv top trim: Prices

Sierra’s Adventure+ trim is more affordable in most configurations.

Sierra’s Adventure+ trim has a more affordable entry point. It is also available with a naturally aspirated petrol engine, while the Curvv gets it only on its lower trims. Also, a turbo-petrol engine on the Curvv can be had with both manual and automatic transmissions, while the Sierra comes only with the latter.

Tata Sierra mid trim vs Tata Curvv top trim: Which one should you buy?

Sierra is the one to go for.

For most buyers, the Sierra Adventure+ trim is the better choice of the two. After all, it comes at a more accessible price point thanks to the NA petrol engine option, and its turbo-petrol unit packs more grunt than the Curvv’s. Moreover, it boasts the most spacious rear seat in its class, an area where the Curvv struggles due to its coupe styling. While the Curvv clearly has an edge in terms of the equipment list, the Sierra’s Adventure+ trim still offers most features without any major compromise.
