Tata’s TGDi engine is set to debut in the Curvv, Sierra. – Dubai Car News

Tata Motors showcased a series of its upcoming products at this year’s Auto Expo in Noida, including concept cars, future EVs and CNG versions of its existing models.

Additionally, the brand also confirmed that they are making a new generation of direct injection 1.2L and 1.5L turbo petrol engines. The two new turbocharged gasoline direct injection (TGDi) petrol engines in the Tata Motors family will debut on the Curvv and Sierra and will also power the new petrol versions of the Safari, Nexon and Altroz.

About Tata’s new engines

Both the turbo-petrol motors comply with BS6 Phase 2 emission norms, i.e. Red Driving Emission Norms (RDE).

The new engines are built using lightweight aluminum and are rigid in construction. Apart from being punchier, these engines are also said to be more refined and fuel efficient. Tata has enabled the engines to run on E20 fuel, which is a blend of petrol with 20% ethanol.

The engines feature dual cam passing, variable oil pump, and exhaust integrated into the cylinder head for excellent fuel economy, and a water-cooled turbocharger for excellent low-end torque delivery.

Tata Motors’ Product Line Vice President Mohan Savarkar has hinted that these new turbo-petrol engines may be mated to a dual-clutch transmission (DCT). According to Tata, consumable engine components such as the timing chain and valve train are designed with low maintenance costs and long-term reliability.

1.2 TGDi Engine: Specifications

The 1.2-litre, three-cylinder motor churns out 1,198cc of 125PS of power at 5,000 rpm and 225Nm of torque between 1,700 and 3,500 rpm. But in other, smaller vehicles, it will deliver a lower torque output of 190Nm.

Tata will introduce this new turbo-petrol engine in 2024 on the Curvv coupe-SUV, which debuted in concept form at the Auto Expo 2023. This engine will later be offered in Nexon and Altroz ​​as well.
