The Tata Harrier has undergone various changes since its launch in 2019, with multiple aesthetic revisions and media upgrades, but now Tata Motors plans to take its flagship SUV in a new direction by updating its mechanical powertrains.

Tata has officially announced the following three available powertrain UPGRADES for the 2025 Tata Harrier:

1. All-electric model

2. new supplied 1.5L turbo petrol engine; and

3. A more powerful diesel engine.

Tata Harrier EV – Launching 3rd June 2025

The new Harrier EV is easily the headline act, officially launching on June 3rd, 2025. It will be built on Tata's newer Gen 2 Acti.ev architecture and will have more than one battery option, with more than 500km of range and a singular AWD motor with a maximum torque of 500Nm, making it one of the most accomplished electric vehicles in its segment.

We are seeing Tata's growing electric vehicle (EV) portfolio, and the Harrier EV should raise the electric vehicle performance bar considerably for midsize SUVs.

Tata Harrier Petrol – Turbocharged E20

Next, Tata will release a petrol-powered variant of the Harrier, which has been spotted on test in India already. This variant will sport a 1.5L turbocharged TGDi petrol engine, producing 170PS and 280Nm of torque. It complies with BS6 Phase II, and it will be compatible with an E20 blend of ethanol. This means a better fuel economy and lower emissions.

A petrol variant has been a long-time coming for the Harrier, and since the urban buyer typically gravitates toward a smoother and quieter driving experience, this variant is bound to attract buyers.

Upgraded Diesel Engine – Fiat’s 2.0L Multijet

Tata also gained licensing rights to Fiat’s proven 2.0L Multijet diesel engine that is currently used by the Harrier and Safari. While IP rights are still held by Stellantis, Tata is now freer to upgrade and localise this powerhouse of an engine.

The FAM B diesel motor will be manufactured at the Ranjangaon plant and will be further improved to provide better performance, reliability, and the capabilities to follow future emission standards.

With these upgrades, Tata can allow the Harrier to expand its reach across multiple buyer segments, from EV adopters to performance petrolheads, and eventually even to diesel believers.
