The Mazda 3 has long been one of Australia's favourite small cars, and the SP25 Sedan adds a more capable engine to the popular formula. The 2.5-litre SKYACTIV-G four-cylinder produces 138 kW of power and 250 Nm of torque, giving the SP25 a noticeable performance advantage over the standard 2-litre variants in the range.

The i-stop system automatically shuts down the engine when the car is stationary and restarts it quickly when needed, helping to reduce fuel consumption during urban driving. It is one of several technologies Mazda has introduced as part of its SKYACTIV approach to efficiency without sacrificing driving engagement.

The SP25 Sedan competes in a class full of accomplished rivals. Buyers looking for a small car with a more involving drive and a genuine six-speed manual option will find the SP25 a satisfying choice.
