When Tata resurrected the Sierra nameplate in 2025, it returned not just as a styling nod to the past but as a seriously roomy mid-size SUV. Size matters — whether you’re choosing a family car, planning long trips, or just hauling weekend gear. In this piece we break down the Sierra’s key exterior dimensions and compare them — dimension by dimension — with some of its most common rivals in India: Hyundai Creta, Kia Seltos, Skoda Kushaq and Maruti Grand Vitara. The numbers tell a clear story about packaging, passenger space and practicality.
Tata Sierra — headline dimensions
Tata’s 2025 Sierra emphasizes cabin space and cargo capability. Its headline dimensions are: Length 4340 mm, Width 1841 mm, Height 1715 mm and Wheelbase 2730 mm, while Tata lists a boot capacity of 622 litres and a ground clearance of about 205 mm. Those figures point to a vehicle designed to prioritize interior room and luggage capacity.
Quick look — rivals’ dimensions
Here are the comparable dimensions for the rivals we’re using in this comparison (official/manufacturer-trusted spec sources):
- Hyundai Creta — Length 4330 mm, Width 1790 mm, Wheelbase 2610 mm, Boot ~433 L.
- Kia Seltos — Length 4365 mm, Width 1800 mm, Wheelbase 2610 mm, Boot ~433 L.
- Skoda Kushaq — Length 4225 mm, Width 1760 mm, Wheelbase 2651 mm, Boot ~385 L (compact-SUV class).
- Maruti Grand Vitara — Length 4345 mm, Width 1795 mm, Wheelbase 2600 mm, Boot ~373 L (varies by powertrain/variant).
(These are manufacturer / major-portal published specs — good benchmarks for cross-model comparison.)
Dimension-by-dimension analysis
Length
Sierra’s length of 4340 mm puts it in the same ballpark as Grand Vitara (4345 mm) and slightly longer than Creta (4330 mm). Seltos is marginally longer at 4365 mm, but length alone doesn’t guarantee cabin space — packaging and wheelbase are the real determinants.
Width
Where Sierra really stands out is shoulder room potential: at 1841 mm it’s notably wider than Creta (1790 mm), Seltos (1800 mm) and Kushaq (1760 mm). More width usually translates to better shoulder-room and a more comfortable three-across rear seat for short trips.
Height
At 1715 mm, Sierra is taller than most competitors. Higher rooflines deliver more headroom, a loftier seating posture (which many buyers prefer) and a roomier cabin feel — particularly for taller passengers.
Wheelbase
Sierra’s wheelbase is 2730 mm, which is significantly longer than Creta/Seltos (both 2610 mm) and Grand Vitara (2600 mm). A longer wheelbase directly helps rear-seat legroom and ride composure: more distance between axles typically gives occupants more usable interior space. That difference is one of the strongest indicators that Sierra will feel more spacious inside.
Boot / cargo space
Tata quotes 622 litres of boot volume — a standout figure in this set. Most rivals sit in the ~370–433 L range; Creta and Seltos are near 433 L while Grand Vitara and Taigun/Kushaq are smaller. If you regularly carry luggage, sports gear, or pushchairs, Sierra’s cargo room is a major practical advantage.
What the extra size means in daily life
Bigger numbers translate into tangible benefits:
- Family comfort: Longer wheelbase + greater width = noticeably more rear legroom and shoulder space. Adults in the back will appreciate the extra room on long journeys.
- Luggage capacity: 622 L boot means you can carry more bags without folding seats. Great for weekend getaways or airport runs.
- Presence and practicality: Taller ride height + wider stance improves visibility and the sense of space inside, and can help on rougher roads thanks to higher ground clearance.
Potential trade-offs
Size also brings typical trade-offs:
- City parking & maneuvering: Wider length and greater height may make tight urban parking and narrow lanes trickier compared with smaller rivals.
- Fuel / efficiency considerations: Heavier or larger vehicles can carry a fuel or energy penalty (or require bigger batteries if electrified). Always compare powertrain efficiency alongside dimensions.
- Price and running costs: Larger packaging and higher equipment levels can push price up — check variant pricing against your needs.
Who should pick the Sierra — and who shouldn’t
Choose Sierra if: you need roomy rear seats, carry lots of cargo, or prefer a taller, commanding driving position for family travel and weekend trips. The Sierra is aimed at buyers who value practicality and space above squeezing into the smallest parking spot.
Consider rivals if: most of your driving is in dense urban areas, you prioritize lower running costs or tighter maneuverability, or your family is small and you don’t regularly use large luggage capacity.
Conclusion
Measured dimension-by-dimension, the 2025 Tata Sierra positions itself as one of the more generously proportioned mid-size SUVs in its class. Its long wheelbase, wide body and huge 622-litre boot give it clear advantages in passenger comfort and cargo carrying over many of the popular rivals — especially Hyundai Creta and Skoda Kushaq — while Seltos and Grand Vitara remain close competitors on length but not on cabin packaging and boot space. If interior space and luggage capacity are top priorities, Sierra is a compelling choice.
