Tata’s Harrier and Safari are set to receive a new powertrain option, with both models launching the 1.5-litre TGDi petrol engine on 9th December 2025. The new engine is part of Tata’s “Hyperion” series and will debut on the Tata Sierra. It is the same 1.5-litre four-cylinder direct-injection turbo petrol unit that was first revealed at the Auto Expo 2023. This addition fills a gap in the company’s portfolio since both SUVs until now were offered only with diesel powertrains. The move is expected to help Tata Motors reach buyers in areas where diesel-powered vehicles face restrictions, as well as those looking for petrol powered SUVs in this segment.
Engine Specifications
Under the bonnet, the turbo-petrol engine makes around 170 HP and 280 NM of torque. The torque is delivered in a broad band between roughly 2,000 and 3,500 RPM, which should help with everyday drivability. Transmission options are expected to include both a six-speed manual and an automatic gearbox. Though the exact form of the automatic, whether torque converter or dual clutch, has not been confirmed yet. Pricing is anticipated to be slightly below that of equivalent diesel variants, which could make these petrol versions more accessible. The diesel versions currently offer similar power but higher torque. For instance the 2.0-litre Kryotec diesel engine in these SUVs makes 170 HP and about 350 NM of torque.
Market Context & Buyer Considerations
With this launch, Tata Motors aims to provide petrol-engine alternatives in a segment where many rivals already offer petrol and diesel options. This could be particularly beneficial in cities with stricter diesel regulations. From a buyer’s perspective, the new engine promises refined performance and likely lower noise and vibration levels compared to diesel. Additionally, Jeep will borrow this engine for its Compass and Meridian in India. Given that the launch is on December 9, deliveries are expected to begin in early 2026. Waiting periods and variant-specific pricing will also play a role in how these new variants perform commercially.
