Engine Displacement: 1,197 cc
The Maruti Suzuki Wagon R features the advanced 1.2-litre K12N Dual Jet, Dual VVT petrol engine. This four-cylinder powerhouse is engineered for a balance of spirited city performance and class-leading thermal efficiency. Utilizing two injectors per cylinder, it ensures precise fuel atomization and smoother power delivery across the rev range.
Max Power: 88.50 bhp @ 6000 rpm
In its 1.2L configuration, the Wagon R produces a peak power of 88.50 brake horsepower. This output is significant for its weight class, providing a power-to-weight ratio that makes it one of the most agile hatchbacks in the "tall-boy" segment. The peak power is achieved at 6000 rpm, allowing for confident highway overtaking.
Max Torque: 113 Nm @ 4400 rpm
The engine generates a maximum torque of 113 Newton-meters at 4400 rpm. This torque curve is optimized for urban drivability, reducing the need for frequent gear changes in stop-and-go traffic. The Dual VVT (Variable Valve Timing) system helps maintain a healthy spread of torque even at lower engine speeds.
No. of Cylinders: 4
While the base 1.0L variants utilize a 3-cylinder layout, the premium 1.2L variants are equipped with a 4-cylinder configuration. This extra cylinder significantly improves NVH (Noise, Vibration, and Harshness) levels, providing a smoother idle and a more refined engine note during acceleration compared to its smaller sibling.
Valve Train: DOHC
The Wagon R employs a Double Overhead Camshaft (DOHC) arrangement with 4 valves per cylinder (16 valves total for the 1.2L). This setup allows for more direct valve control and improved high-speed breathing, which is essential for the engine's Dual VVT system to operate efficiently.
Fuel System: MPFI (Multi-Point Fuel Injection)
The fuel delivery is handled by a sophisticated Multi-Point Fuel Injection (MPFI) system. For the 2025 model, this system is tuned to be E20 compatible (20% Ethanol blend), adhering to the latest environmental norms while maintaining a high fuel economy of approximately 23.56 km/l to 25.19 km/l depending on the variant.
0-100 km/h Time: 12.6 Seconds
The 1.2L Wagon R clocks a 0-100 km/h sprint in approximately 12.6 seconds. While not a sports car, this performance is highly competitive for the entry-level hatchback segment, allowing the vehicle to feel peppy and responsive during initial take-off from traffic lights.
Top Speed: 165 km/h
Under controlled conditions, the Wagon R can reach a top speed of 165 km/h. However, due to its tall-boy design and lightweight Heartect platform, stability is best maintained at cruising speeds of 80–100 km/h. The vehicle includes a mandatory speed alert system that beeps once at 80 km/h and continuously above 120 km/h.
