Tata Harrier: Mileage Review

Last Updated on: 12 Oct 2026
The Tata Harrier range runs across 50 variants, and the structure is simpler than that number suggests. It begins with Smart and Pure X, moves through Adventure X and Adventure X+, and finishes with Fearless X and Fearless X+. A Stealth finish is reserved for the very top variant.
The base model Smart 1.5 Turbo-GDI MT already covers the safety equipment. Six airbags, stability control, traction control and tyre pressure monitoring are fitted to every variant rather than only the expensive ones. That matters if your budget sits at the lower end, because you are not trading away crash protection to save money.
The is where most of the everyday equipment arrives, and the top model Fearless Ultra Stealth 2.0 Diesel AT adds the items that are exclusive to the very top of the range.
Which variant gets which features:
The 12.3-inch touchscreen is fitted to diesel variants, while the larger 14.53-inch screen is reserved for the top petrol variants.
Driver assistance features including blind spot warning, lane departure warning and traffic sign reading appear on the higher variants only.
Adaptive cruise control is limited to automatic variants, so the gearbox you pick decides whether you can have it.
The panoramic sunroof, ventilated front seats and the 360-degree camera all sit above the base model Smart 1.5 Turbo-GDI MT.
The seventh airbag and the dashcam mirror are top model items.

Hi, I am about to book Tata Harrier petrol automatic as my running is less but I am confused between Adventure X and Adventure X+ and there is only 35 to 45,000 rupees difference between these two variants in the showroom from where I am about to book the car.
With only Rs 35,000-45,000 separating the Adventure X and Adventure X+ at the dealer, the X+ is the one to choose. The two Tata Harrier variants have the same 1.5-litre turbo petrol engine and six-speed torque converter automatic, so there is no difference in performance or basic driving experience.The extra money on the X+ gets you Level 2 ADAS, electronic parking brake with Auto Hold and rear disc brakes. The Adventure X already gets the important equipment such as the panoramic sunroof, 17-inch alloys, 360-degree camera, digital instrument cluster and six airbags.For just Rs 35,000-45,000 more, the X+ additions are worthwhile, particularly Auto Hold for everyday traffic and the additional driver assistance features for highway use.
I purchased a Kia Sonet 1.0 iMT in 2024 after owning Maruti Suzuki Dzire for around 11 years. I was so bored of driving it for more than a decade that I rushed to change. I wanted a compact SUV as an upgrade but settled for a sub-compact SUV due to budget constrain or may be due to lack guidance and understanding. Soon after buying it, I realized that this is not the car that I want to drive. I want a vehicle that looks and feels rugged but at the same time, is usable for daily commute with 80 - 90% city drive. I want to feel the same way I feel when I drive my Royal Enfield (strong and rugged). In less than 3 years, I am looking for a change again but this is time I don't want to make the same mistake. I have a few cars in mind but I am not sure which one should I go for. I have shortlisted Renault Duster Hybrid (upcoming), Tata Harrier AT (diesel), Thar Roxx AT (diesel), Toyota Hyryder Hybrid and Hyundai Creta AT (Diesel or Petrol). I drive around 1000 to 1200 km per month, mostly in the city but when I plan for long drives to mountains in Himachal, Uttarakhand or even Leh, I shouldn't have to worry about it. My budget is between 17 to 19 lakh (ex-Showroom). Please advise.
Go for the Renault Duster Hybrid when it launches. It is the best fit for what you are looking for. You want a car that feels rugged and strong like your Royal Enfield, but is still usable for daily city driving. The Duster has always been known for its tough, no-nonsense character and excellent ride quality, and the new generation continues that tradition. The hybrid powertrain will make it much more suitable for your 80-90% city driving, while still being capable enough for long drives to the mountains without you having to worry about fuel efficiency or reliability.The Tata Harrier diesel is a good car, but it is a much larger vehicle and not as easy to live with in the city. The Thar Roxx/OG is a great lifestyle vehicle, but it is not practical as a daily driver. The Toyota Hyryder Hybrid is a sensible choice, but it does not have the same rugged character you are looking for. The Hyundai Creta diesel is a good all-rounder, but it does not feel as tough or as special as the Duster. With your running, you could consider the 1.3 turbo petrol Duster with the DCT as well. It is not the most efficient engine and gearbox combination, but given your limited running, the fuel economy penalty should not be significant.
I am currently driving Maruti Suzuki Swift Dzire VDi (2013) diesel manual. I want to decide between Tata Harrier Adventure X Plus DK and Tata Sierra accomplished (both diesel). On Harrier, I am getting discount of approximately 1.6 lakh and on Sierra, I am getting approximately 70,000 discount. Which one should I prefer? My daily driving is approximately 70km with 80% driving on state highway and 20% in city. There is no budget constraint.
For your 70km daily running with 80 percent on state highways, the Harrier is the better fit. The 2.0-litre diesel produces 170hp and 350Nm, making it considerably more effortless than the Sierra’s 1.5-litre diesel, particularly for overtaking and sustained highway cruising. The Harrier also has excellent high-speed stability and ride quality, which should suit your usage well.The Sierra Accomplished Diesel is the newer and more compact option. It has a slightly better ride over broken roads and its smaller dimensions will make it easier to manage in the city. Its diesel is also more economical in real-world testing, but the difference is small on the highway: 14.56kpl for the Sierra versus 14.36kpl for the Harrier.In your case, the Rs 1.6 lakh discount on the Harrier makes the decision even easier. You get the larger, more powerful engine, better highway performance and a substantial discount, while the Sierra is still a new product without a long-term ownership track record.
I’m looking for a car in the Rs 22-24 lakh budget. My daily usage is around 30km, with about 75 percent of the driving in the city. My priorities are safety, driving comfort, mileage and an automatic gearbox. I was initially looking for a 5-seater and liked the Harrier Petrol Automatic, but I am now also considering a 7-seater. Should I choose between the Harrier, Safari and XUV 7XO, and would petrol or diesel be more suitable for my usage? I’m also open to other suggestions that fit these requirements.
Go for the Mahindra XUV 7XO diesel automatic. With your 30km daily running and 75% city usage, diesel still makes sense because the 7XO’s diesel engine is efficient, refined and well suited to both city and highway driving. The XUV 7XO also offers a more modern cabin, better tech and a more premium feel than the Harrier and Safari. It is also a genuinely comfortable 7 seater with a usable third row, which gives you added flexibility. The Tata Harrier petrol automatic is a good car, but the petrol engine is not as efficient and the overall package feels a bit older compared to the 7XO. The Tata Safari is essentially a 7 seater version of the Harrier, so the same comments apply. The 7XO diesel automatic is the best fit for your priorities of safety, driving comfort, mileage and automatic transmission.
Tata Harrier Diesel Automatic Adventure Plus Dark Edition or new Kia Seltos Diesel Automatic GTX with ADAS? Both fall in the same price range. Which would be the better buy for long-term ownership? I may keep the car for at least 10 years, and most of my usage will be on highways. The Harrier is bigger and more powerful, but I have some concerns about Tata's overall quality, especially the electricals, service and small niggles. Which of the two would be the better choice?
Go for the Kia Seltos Diesel Automatic GTX. For a 10-year ownership plan with predominantly highway usage, the Kia Seltos is the safer long-term bet. The Tata Harrier is the more powerful and rugged SUV, and it feels more planted on the highway, but Tata still has some way to go in terms of consistency in electricals, service experience and small niggles over a decade of ownership.The Seltos diesel is a proven package, the GTX is a well-equipped variant, and Kia’s service network and ownership experience are more consistent over the long term. The Seltos is also a very capable highway car, and the diesel engine is well suited to long-distance touring. The Harrier is the better choice if you absolutely prioritise size, road presence and ruggedness, but for a 10-year ownership plan, the Kia car mentioned above is the more sensible and dependable choice.
