The 2.0-liter turbocharged diesel engine powers the flagship SUVs from Tata Motors; there are presently no gasoline engines available.
For a long time, Tata Motors has been developing a new gasoline engine. The 2023 Auto Expo was when the 1.5-liter tGDi gasoline engine made its debut. It was previously thought that this new engine would make its debut by the end of 2024 or the beginning of 2026, however the date has been moved forward.
March 2026 is the anticipated launch date for the new 1.5-liter four-cylinder tGDi engine, according to the most recent reports. We now know that the engine will generate 168 horsepower and a maximum torque of 280 Nm. In addition, depending on the model and type, it should be available in a variety of tune states.
Although the turbo gasoline engine‘s transmission choices are yet unknown, a true 7-speed DCT automatic gearbox is probably in the cards. Furthermore, the package will also have a 6-speed manual gearbox.
The flagship models of the Indian automaker, the Harrier and Safari, now only have a 2.0-liter diesel MultiJet engine from Fiat that produces 168 horsepower and 350 Nm of peak torque. It has a 6-speed torque converter automatic transmission and a 6-speed manual gearbox linked to it. Due to the lack of a gasoline engine, competitors that have both diesel and gasoline engines outperform the Tata SUVs.
Additionally, purchasers of new cars are shifting to gasoline engines as pollution regulations get stricter. Among the benefits of gasoline engines are their cheaper cost, lack of DPF (diesel particulate filter) problems, reduced maintenance expenses, and reduced emissions.
First to use the new 1.5-liter tGDi petrol engine will be the Tata Harrier and Safari. In addition, the forthcoming Sierra SUV will also include a turbocharged gasoline engine. India has seen the test mule of these SUVs with petrol engines on several occasions.
Given that it is an internal engine, we anticipate that the Tata Harrier and Safari petrol will cost about Rs. 1 lakh less than the existing diesel lineup. The 1.5-liter tGDi unit is reportedly the basis for Tata Motors’ 1.5-liter naturally aspirated petrol engine development. Expect the entry-level Sierra models to feature this four-cylinder NA motor.
