The 2006 Mazda MAZDA3 falls within the first generation of the model that debuted in early 2004. Available with a 4-door sedan or 5-door hatchback body style, the 2006 MAZDA3 comes in three trim levels: i, s, and SP23 Special Edition. The i trim offers a 2.0-liter four-cylinder engine with 150 horsepower, while the s and SP23 trims are equipped with a more potent 2.3-liter four-cylinder with 160 horsepower. Both versions route power through a standard five-speed manual or an optional four-speed automatic for the 2.0-liter and a five-speed automatic for the 2.3-liter. The 2006 Mazda MAZDA3 became popular for its sporty character, precise handling, and upscale interior, often outclassing competitors. Safety features include standard four-wheel antilock brakes and front side-impact airbags. However, electronic stability control is not offered.
