Tata Motors is gearing up for one of its most anticipated launches — the 2025 Tata Sierra. A name that carries legacy, nostalgia, and a loyal fan base, the Sierra is making a comeback in an all-new avatar with futuristic design, electric mobility, premium comfort, and industry-leading features. On the other hand, the Tata Harrier remains one of the most successful and feature-rich SUVs in the company’s lineup.

However, the upcoming Sierra brings some exclusive upgrades and next-generation features that set it apart from the Harrier. Whether you’re planning to buy a premium SUV or are curious about what the Sierra brings to the table, here are five major upgrades the 2025 Tata Sierra gets over the Tata Harrier.

1️⃣ Triple-Screen High-Tech Cabin – A More Futuristic Interior

The 2025 Sierra introduces a three-screen layout, something not seen before in any Tata SUV. This includes:

• A digital instrument cluster
• A large central infotainment touchscreen
• A secondary touchscreen for climate and vehicle controls

This triple-screen setup gives the Sierra’s cabin a premium, cockpit-like feel. By comparison, the Harrier offers a dual-screen layout (digital cluster + infotainment), but the Sierra takes the experience a step further by integrating more functions and enhancing the visual appeal.

Why This Matters

• More intuitive control layout
• Improved digital experience for driver and passenger
• More premium and futuristic cabin ambience
• Better integration for navigation, entertainment, and car controls

The Sierra’s cabin feels more tech-loaded, modern, and luxurious, making it ideal for tech-savvy buyers who want the latest innovations in their SUV.

2️⃣ Multiple Powertrain Options Including EV – More Choices Than Harrier

One of the biggest advantages the 2025 Sierra has over the Harrier is its flexible powertrain lineup. While the Harrier is currently available only with diesel (and possibly EV in future), Sierra is expected to launch with:

• Turbo Petrol Engine
• Diesel Engine
• Fully Electric Version

This means the Sierra will offer both traditional and future-ready options, allowing buyers to choose based on their lifestyle and driving needs.

Sierra EV Expected Advantages

• Long driving range (roughly 450–550 km expected)
• Fast charging capability
• Lower running costs
• Instant torque and smoother driving experience

Why Sierra Wins Here

The inclusion of an electric version gives Sierra a massive advantage over the Harrier for buyers switching to electric mobility without sacrificing size, comfort, or capability.

3️⃣ Distinctive Retro-Modern Design – A Style Statement

The Sierra has always been an icon, and the 2025 model proudly carries forward its legacy. Tata has modernised the classic design while retaining some signature elements. Compared to the Harrier’s muscular and aggressive design, the Sierra leans towards a cleaner, more futuristic appeal.

Design Features That Make Sierra Unique

• Full-width LED DRLs at the front and rear
• A modern interpretation of the iconic Sierra glasshouse
• Squared-off body, giving it a bold and timeless silhouette
• Flush door handles
• New-age alloy wheel design
• SUV-coupe-like elegance with upright stance

Why Sierra Stands Out

The Sierra offers an emotional connection through nostalgia while still looking incredibly modern. Harrier has a strong road presence, but Sierra has styling that is premium, futuristic, and instantly recognisable — making it a head-turner.

4️⃣ Advanced Comfort & Safety Features – More Premium Than Harrier

Tata is adding several next-level comfort and safety features in the upcoming Sierra, making it feel more premium than the Harrier. The Sierra is expected to bring:

Comfort Features

• Ventilated front seats
• Dual-zone climate control
• Wider and softer seats
• Panoramic sunroof
• Premium cabin materials
• Rear seat recline (expected)
• Advanced ambient lighting

Safety Features

• ADAS Level 2
• 360-degree camera
• Blind-spot detection
• Rear-cross alert
• Tire-pressure monitoring
• Multiple airbags
• Electronic stability enhancements

While the Harrier already offers several of these features, Sierra’s upgraded ADAS system and more premium comfort features make it a more refined and future-ready SUV.

Why Sierra Leads

The Sierra is designed as a flagship SUV with a stronger focus on luxury and advanced tech, while Harrier sits slightly lower in Tata’s hierarchy.

5️⃣ Better City-Friendly Driving Experience – Practical for Urban Use

Even though Sierra is expected to be similar in size to the Harrier, its platform, design, and powertrain tuning make it more practical and efficient for city driving.

What Makes Sierra Better for Urban Users

• Smoother power delivery (especially in EV variant)
• Compact yet spacious design
• Better steering response for urban manoeuvring
• Regenerative braking in EV improves efficiency
• Lower running cost per km (EV and turbo-petrol over diesel)
• Quieter cabin and smoother ride in city conditions

Why This Matters

Urban users face traffic, narrow roads, and frequent stopping. Sierra’s electric powertrain, modern suspension tuning, and responsive steering make it easier and more economical for everyday driving.

Bonus Advantage: A More Premium Ownership Experience

Tata is positioning the Sierra as a more premium offering, likely above the Harrier in the lineup. This means:

• Better interior materials
• More features in top variants
• More connected tech
• Enhanced build quality focus

The Sierra is expected to appeal to buyers who want a flagship-level Tata SUV without going all the way up to Safari.

Conclusion: Should You Choose Sierra Over Harrier?

Both SUVs have their own strengths, but if you’re someone who wants the newest tech, modern design, future-ready EV options, and premium feel, then the 2025 Tata Sierra clearly stands ahead of the Harrier.

Sierra Wins In:

• Technology
• Cabin experience
• Powertrain choices (especially EV)
• Futuristic design
• Comfort and safety features

Harrier Still Shines In:

• Diesel performance
• Proven reliability
• Strong highway presence

But with its triple screens, EV options, retro-modern looks, and premium feature list, the Sierra is Tata’s next big step forward — and those upgrades make it one of the most exciting SUVs of 2025.
