The high-performance diesel boasts a flat torque curve throughout the rev range for superb all-round performance. Its common-rail direct-injection system helps cut down emissions, while making the engine one of the most powerful in the class. The engine generates 88 kW/3,500 rpm of power and 280 N・m/2,000 rpm of torque. It powers the 4X2 model from 0 to 100 km/h in 10.5 seconds (11.2 seconds for the 4X4 model). The 4X2 model gets 6.3 litres to 100 kilometres in the Combined Mode (6.4 litres for the 4X4 model). A diesel particulate filter is standard. A 1.6-litre VVT (variable valve timing) petrol engine and a 1.5-litre petrol engine round out the line-up. Both 16-valve engines are fitted with electric control throttle bodies, for good drivability and response. All three engines comply with Euro 4 regulations.
A six-speed manual transmission newly developed by Suzuki is paired to the diesel engine. It was engineered with six gears to enable a close-ratio tuning that brings out the potential of the engine.
A five-speed manual is available for both petrol engines and a four-speed automatic for 1.6-litre petrol engine.

The signature feature of the Suzuki SX4 is i-AWD, a switchable three-mode 4X4 system. An Electric Control Coupling Device enables 4WD-Auto, 4WD-Lock, and 2WD modes. Under normal driving conditions while in the 4WD-Auto mode, torque is not transferred to the rear, resulting in a near FF layout. Torque is automatically apportioned to the rear wheels when pronounced front wheel slip occurs to produce 4X4 traction and enhance stability. The 4WD-Lock mode is maintained until 60 km/h for full traction, before automatically switching over to the 4WD-Auto mode for smooth cruising. The 2WD mode offers excellent fuel economy.
