The Tata Sierra and Curvv mid-size SUVs are sold under the same brand, but are positioned quite differently in Tata’s lineup. The Curvv is built on the modified ATLAS platform, which is a modified version of the Nexon’s X1 platform, and features an SUV-coupe bodystyle. On the other hand, the Sierra is built on a new ARGOS platform, positioned above ATLAS, and gets a traditional SUV look, possessing larger dimensions, and is a more premium product. Both get an identical diesel engine, but come with different petrol engines altogether. 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 of the two offers better value.

Tata Sierra mid trim vs Tata Curvv top trim: Specifications
Curvv top trim skips the naturally aspirated petrol engine
Both SUVs share the same 1.5-litre diesel engine, albeit the Sierra’s diesel is paired to a torque converter while the Curvv gets it with a DCT gearbox. Also, both feature the Hyperion series of turbo-petrol engines, but the Sierra’s unit delivers substantially more power and torque figures on account of higher displacement. While all the engine configurations of the Curvv and Sierra can be paired with either manual or automatic gearboxes, the Sierra’s turbo petrol is sold only with an automatic transmission. Notably, the Curvv’s engines are paired to DCT gearboxes, while the Sierra’s engines are mated to a torque converter automatic.
Tata Sierra mid trim vs Tata Curvv top trim: Exterior
Both evenly matched on the exterior
On the outside, both models feature similar equipment, but the Sierra’s Adventure+ trim is also sold with 17-inch alloys with the naturally aspirated engine, thus lending it better ride quality. The Curvv’s top trim can be had with monotone and dual-tone paint options, while the Sierra only gets the former option.

Curvv gets more feel-good features, but Sierra gets more convenience features
Both SUVs come feature-packed with similar screens for the infotainment and instrument cluster, panoramic sunroof, wireless Apple CarPlay and Android Auto and dual-zone climate control. But the Curvv Accomplished+ gets front seat ventilation, a powered driver seat, a JBL 9-speaker sound system, a powered tailgate, connected car tech, leatherette upholstery, an air purifier, and a wireless phone charger. However, the Sierra Adventure+ gets a manual boss mode, extended under-thigh support for the front seats and more USB ports with higher power output.

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 a basic safety kit including six airbags, ABS and EBD, ESC, hill start assist, and hill descent control, while also fitting a 360-degree camera and blind view monitoring. However, the Curvv comes with a Level 2 ADAS suite and an auto-dimming IRVM, but the Sierra gets additional parking sensors at the front.
Tata Sierra mid trim vs Tata Curvv top trim: Prices
Sierra’s Adventure+ trim is more affordable in most configurations
Sierra’s Adventure+ trim begins from a more affordable price point. It is also available with a naturally aspirated petrol engine, while the Curvv gets it only on its lower trims. On the other hand, a turbo-petrol engine on the Curvv can be had in both manual and automatic transmissions, while the Sierra comes with the latter option solely.
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. Not only does it offer a more accessible price point, thanks to its additional engine option, but it is also more affordable considering all powertrain configurations. Moreover, it has the most spacious rear seat in its class, an aspect that the Curvv doesn’t do well at. While the Curvv clearly has an edge in terms of the equipment list, the Sierra’s Adventure+ trim still gets most features, without a large compromise. Furthermore, the Sierra’s mid trim offers an additional engine option and much more power in turbo-petrol guise.
