Engine Specifications:
- Displacement: The engine displaces 1,198cc across its three cylinders, compact yet robust for various driving conditions.
- Cylinders: Its 3-cylinder configuration balances efficiency and performance, employing modern turbocharging and direct injection to punch above its weight.
- Power Output: It delivers 123–125 bhp at 5,000rpm, a noticeable increase in horsepower compared to Tata’s earlier engines, particularly the Nexon’s Revotron unit. This added power is crucial for heavier vehicles like the upcoming Tata Curvv.
- Torque: The engine produces a robust 225 Nm of torque between 1,700 and 3,500rpm. This broad torque band ensures that the Hyperion engine delivers ample pulling power in real-world driving conditions, whether accelerating from a standstill or overtaking at highway speeds.
- Fuel Injection: Tata has equipped this engine with a 350-bar fuel injection system paired with machine learning technology, optimizing fuel delivery for performance and efficiency. The system’s precision improves throttle response, making the engine more responsive while reducing fuel consumption and emissions.
Design and Technology
- Material: The engine’s lightweight aluminum construction significantly reduces weight while improving stiffness, improving fuel efficiency, handling, and overall vehicle dynamics. The reduction in mass helps mitigate Curvv’s added weight from its larger footprint and extended wheelbase.
- Turbocharger: A water-cooled variable geometry turbocharger (VGT) is at the heart of the Hyperion’s enhanced performance. This advanced turbo setup increases power output and improves the engine’s low-end torque delivery, resulting in smoother and faster acceleration across various driving scenarios.
- Variable Valve Timing: The central-mounted dual variable cam timing system dynamically adjusts valve operation based on engine speed and load, improving efficiency and smoother power delivery across the entire rev range. This system enhances fuel economy during low-speed driving and delivers maximum power when needed.
- Exhaust System: The integrated exhaust manifold works with a 3-way catalyst at the front and a 4-way conversion catalyst at the rear. These components help manage emissions, ensuring the engine complies with strict environmental standards without sacrificing performance.
- Piston and Valves: Friction-optimized pistons feature a steel ring carrier for enhanced durability under high loads. Additionally, sodium-cooled exhaust valves ensure that temperatures remain controlled, even during extended periods of high-performance driving, thus improving the engine’s longevity and efficiency.
Compliance and Efficiency
- BS6 Phase 2 & E20 Compliant: Designed to meet India’s stringent BS6 Phase 2 emissions standards, the Hyperion engine is future-ready. It is also E20 fuel compliant, capable of running on a blend of 20% ethanol and 80% petrol. This reduces carbon emissions and aligns with India’s push toward alternative fuels and energy efficiency.
- Refinement: Tata has placed a strong emphasis on refinement with the Hyperion. Compared to the older Revotron engine, the Hyperion is quieter and smoother, offering a more sophisticated driving experience. Reduced engine noise, vibrations, and harshness (NVH) levels make the Curvv a more comfortable vehicle for longer drives, particularly on uneven roads where engine harshness can be more apparent.
Transmission Options
- 6-Speed Manual: This standard transmission option gives drivers greater control over gear selection, which is ideal for enthusiasts and those who prefer a more hands-on driving experience.
- 7-Speed Dual-Clutch Transmission (DCT): The Hyperion will also offer a 7-speed DCT, bringing a sportier and more responsive driving experience. The quick gear shifts of the DCT complement the engine’s low-end torque, delivering a seamless and exhilarating driving experience, especially in city traffic and during overtakes.
Performance in the Tata Curvv
The Hyperion engine is expected to power Tata’s new midsize SUV, the Tata Curvv, a vehicle that demands higher power output due to its larger size than the Nexon. The five bhp and 55 Nm increase over the Nexon’s engine is designed to compensate for the Curvv’s extended wheelbase and additional weight, ensuring smooth performance under load.
With this engine, Tata Motors has focused on balancing performance and fuel economy, making the Curvv not just a powerful SUV but also a practical one for daily commutes and long-distance travel. The Hyperion’s low-end torque will especially shine during stop-and-go traffic, offering superior drivability in urban environments.
First Appearance
The Hyperion engine was first showcased at the Auto Expo 2023, marking a significant milestone for Tata Motors in developing efficient, high-performance petrol engines. It was officially named and unveiled through Tata Motors’ promotional content in anticipation of the Tata Curvv’s launch later this year.
In summary, the Tata 1.2-litre TGDi Hyperion engine is a powerhouse of innovation, combining advanced fuel injection systems, turbocharging technology, and lightweight materials to deliver a powerful and refined engine. Whether you prioritize performance, fuel efficiency, or environmental responsibility, the Hyperion engine sets a new benchmark in Tata’s lineup, with the Tata Curvv expected to showcase its capabilities in full.
