Engine Displacement: 1,197 cc
The Tata Punch is powered by the 1.2L Revotron naturally aspirated petrol engine. This 3-cylinder unit is engineered with DynaPro technology, which optimizes the combustion process to provide a balance between fuel efficiency and low-end torque. While it is a 3-cylinder configuration, Tata has utilized offset crank and advanced engine mounts to mitigate the inherent vibrations typical of this layout.
Max Power: 87.8 bhp @ 6000 rpm
The peak power output is rated at 87.8 bhp (approximately 88 PS), allowing the vehicle to maintain highway speeds comfortably. The power delivery is linear, making it predictable for urban commutes. In CNG mode, the power output is electronically limited to approximately 73.5 PS to optimize fuel thermal efficiency.
Max Torque: 115 Nm @ 3250 rpm
The engine produces a peak torque of 115 Nm, which kicks in relatively early in the rev range. This "torque-on-demand" characteristic is vital for the Punch's ability to navigate steep inclines and start from a standstill with a full passenger load without significant clutch slippage.
No. of Cylinders: 3
The inline 3-cylinder configuration is chosen for its lightweight properties and reduced internal friction compared to 4-cylinder counterparts. This helps the Punch achieve better fuel economy figures, specifically targeting a mileage of nearly 20.09 kmpl in manual variants.
Valve Train: DOHC
The Double Over Head Camshaft (DOHC) setup with 4 valves per cylinder allows for better air-fuel mixture flow at higher RPMs. This contributes to the engine's breathing efficiency, ensuring that the 1.2L displacement is utilized to its maximum potential across various driving modes (Eco and City).
Fuel System: MPFI
The Multi-Point Fuel Injection (MPFI) system ensures precise fuel delivery to each cylinder. Combined with the "DynaPro" air intake system, it ensures a cleaner burn and better throttle response. The system is also designed to be compatible with E20 fuel blends as per the latest emission norms.
0-100 km/h Time: 16.5 Seconds
While the Tata Punch is not designed as a performance sprinter, it clocks a 0-100 km/h time of approximately 16.5 seconds. The focus remains on mid-range driveability rather than standing-start acceleration, which is adequate for its intended use as a city-centric micro-SUV.
Top Speed: 150 km/h
The Tata Punch has an electronically governed top speed of approximately 150 km/h. At these speeds, the ALFA architecture ensures high-speed stability and minimal body roll, though the engine is most comfortable cruising between 80-100 km/h.
