Harrier: Diesel or Petrol?

Tata Motors is one of the oldest car manufacturers in India. The company launched its first passenger vehicle, the Sierra, back in 1991 and has since introduced brand-defining nameplates such as the Indica, Sumo, Safari and Nano. Over the past few years, Tata has further improved its reputation because of their practical engineering: high-strength steel structures, thicker body panels than many rivals at the same price, and a habit of putting six airbags on trims where competitors still charge extra for them. Multiple Tata models, including the Nexon, Harrier, Safari, Curvv and Sierra, have earned five-star crash safety ratings from Bharat NCAP or Global NCAP. Tata car price in India starts at Rs 4.77 lakh (Tiago) and goes up to Rs 29.29 lakh (Harrier EV).
We, at Autocar India, feel one of the reasons for Tata’s success in India is its focus on developing cars with Indian conditions in mind from the outset. Its cars are engineered to suit Indian roads, buyers and running costs, rather than adapting an existing global platform to the Indian market at a later stage.
As of now, there are 21 Tata cars in India, out of which 16 are available for sale, and 5 are upcoming. Those 16 Tata models that are available fall into three body types: SUV, sedan and hatchback, with SUVs having the largest share.
Type | Tata Models | Best suited For |
Tata Hatchback | Tiago, Tiago EV, Altroz | Buyers who want the lowest running costs, easy parking and a car that is simple to manoeuvre through dense city traffic. |
Tata Sedan | Tigor, Tigor EV | Buyers who want a proper boot for long trips, a lower driving position than an SUV, and a comfortable car for city and highway use . |
Tata SUV | Punch, Punch EV, Sierra, Sierra EV, Nexon, Nexon EV, Curvv, Curvv EV, Harrier, Harrier EV, Safari | Buyers who want a higher seating position, better visibility in traffic, more ground clearance for uneven roads, along with more space for family and luggage. |
Note: There is a further split in the SUV category itself. The Punch and Punch EV are sub-4-meter SUVs, a size that has benefited from lower taxes in India and helped the brand to keep its prices competitive. The Nexon, Nexon EV, Curvv, Curvv EV and Sierra sit a step above as mid-size SUVs, while the Harrier, Harrier EV and Safari are Tata's largest SUVs, with the Safari being the only 7 seater Tata car currently on sale.
We at Autocar India believe the right body type depends much more on how a car will actually be used daily than on which one looks the most appealing in a showroom. A tall SUV that aids on rough roads or when hauling large objects might simply be extra weight and expense for someone who only drives alone in urban traffic.
Before you pick one, we at Autocar India would suggest you consider factors like: your budget, how much city traffic you deal with on a regular basis, and how much you value driving smoothness over price. Here are the transmission options available:
Tata's automatic options span 4 different gearbox types:
Tata currently sells its cars in four fuel types: petrol, diesel, CNG and electric.
Based on questions we (Autocar India) receive from real customers through our advice section, Tata’s after-sales service is a mixed experience rather than being consistently good or bad. It depends largely on the dealership and city. Some owners report smooth and reasonably priced routine servicing, while others have faced problems getting recurring issues fixed.
Common complaints include:
In some serious cases, buyers only got a resolution after escalating repeatedly.
That said, this isn't the experience of every Tata car owner. Plenty of reader questions also show real confidence in specific models and dealerships. The honest takeaway is that service quality depends more on your specific dealership than on the Tata brand as a whole. Therefore, we at Autocar India would recommend checking reviews for your local service center before you buy.

Hear from the
I want to buy a rugged electric vehicle with a minimum average range of 500 km below Rs. 36 lakh (on-road).
Hi, I'm planning for a reliable car for my family for long term ownership. Mostly, I drive within the city with monthly average of 300-500 km and take 2-3 long trips in a year. I had shortlisted Seltos HTX petrol. However, I'm getting recommendations to go with Harrier base under my budget. Should I opt with Seltos or Harrier?
We are a family of 4 and our usage is limited to 10-12,000 km annually which involves 60:40 city-highway usage. Our trips always have a couple of more members joining us. I like the XUV 7XO (diesel) automatic but I am not too sure about its longevity since I would like to own this car for 8-10 years. I considered the Alcazar but I felt the 2nd row is slightly narrow compared to the 7XO. Also, as a car that costs as much as the 7XO isn't nearly as powerful either. Are these my only options? I know my usage may not need a diesel but I would like to own one while these are still available, so I don't mind the delta in price. Also, with the E20 petrol, the performance and efficiency of my current S-Cross has seen drastic difference. I would like the car to be engaging to drive and also reliable with a fuss free ownership. Could you guide me on this please? Thank you.
Please advise which car would be the best choice for long-term ownership: the Mahindra Scorpio, Tata Safari, Tata Harrier, Jeep Compass, Volkswagen SUV, or any other suitable option. My priority is reliability, long-term durability, and hassle-free ownership over the next 10 years or more. I would appreciate suggestions based on real-world ownership experience, maintenance costs, spare parts availability, and after-sales support.
I am confused between the Hyundai Creta Electric and the Tata Sierra EV. I am a little hesitant about the Sierra because of the glitches being reported, whereas the Creta Electric seems to have been relatively problem-free based on what I have heard so far. I also feel that the Creta Electric's motor is better refined, as the motor noise in the Sierra seems to creep into the cabin at speeds above 50kmph. Kindly advise me on which one would be the better choice.

Good car for this price range, perfect for middle-class families. Good points: attractive look, low maintenance, big boot space, comfortable seats, clear sound from the music system, good mileage, strong engine, comfortable for the driver, excellent pickup, and awesome speed. Overall, it's a pocket-friendly car.

Very bad experience with my Tata nexon 2020.. After 37k oil cooler issues, car stopped in between, coolant mixed with engine oil. Replaced all parts in 2025, again same issues recently. Complained to Tata, they don't have any remedy for this. So car is not roadworthy and safe to travel... Very poor quality and service

The drive was amazing; the seat height makes you feel like you're sitting on a throne, great bonnet view, no jerks felt during shifting, as it is smooth!! Also, the overall interior feels calming, with lighter shades.

The Tata Safari uses a tried and tested Fiat engine, and its 3rd row can accommodate adults for medium distances. The steering is better calibrated for driving pleasure.
