The Suzuki Swift 1.2 K12 Engine is a dependable and efficient power unit, part of Suzuki’s modern K-series engine family. This 1.2L inline 4-cylinder petrol engine delivers smooth power, excellent fuel economy, and long-term reliability, making it an ideal choice for engine replacement or upgrades.
Featuring a DOHC 16-valve configuration and multi-point fuel injection (MPFI), the K12 engine provides responsive acceleration, reliable combustion, and consistent performance. Many variants are equipped with Variable Valve Timing (VVT), which enhances torque and fuel efficiency under all driving conditions.
With an output of approximately 86–91 horsepower and torque around 113–115 Nm, the engine is well-suited for city commuting and highway driving alike. Its timing chain system reduces maintenance costs compared to traditional timing belt engines, while the lightweight aluminum construction ensures durability and better heat management.
