The Tata Sierra and Harrier are two of the most popular SUVs in India, both offering petrol and diesel engine options. As seen with other Tata cars, both SUVs are loaded with features to the brim. But which one offers the better feature suite and value for money? Let’s find out.

Both the Sierra and Harrier come with an all-LED lighting setup, 19-inch alloy wheels, a rear spoiler, and powered ORVMs. However, the Sierra has a few additional features, such as flush-type door handles and a memory function for the ORVMs, which are not available on the Harrier.

The Sierra gets an extra screen and 2 additional speakers
The Sierra is the first Tata vehicle to feature a dedicated passenger screen. It also comes with two additional speakers and Dolby Atmos surround sound support, features not available in the Harrier Fearless X+. On the other hand, the Harrier offers a powered co-driver’s seat with a boss mode, which is missing in the Sierra Accomplished+.
Additionally, the Harrier has a higher-spec Fearless Ultra trim, which includes a larger 14.5-inch touchscreen infotainment system, an e-IRVM with an integrated dashcam, front and rear camera washers, and Dolby Atmos support. However, this trim has been excluded from the comparison since it is available only with the turbo-petrol engine option.

The Tata Sierra offers the same turbo-petrol engine as the Harrier Fearless X+, but it is over Rs 1 lakh more affordable.

Tata Sierra vs Harrier: Which SUV should you choose?
The Sierra offers the better-value-for money proposition
While the Tata Harrier is larger, more spacious and offers more powerful engine options, the Sierra stands out by packing in more features at a significantly lower price, including a dedicated co-driver screen, a 12-speaker sound system with Dolby Atmos support, and a memory function for the ORVMs, all at a much lower cost. This makes the Sierra the more recommendable option for those looking for a Tata SUV offering better value.
