Mazda has unveiled a modified version of the high-performance Mazda3 Mazda Performance Series (MPS) at the 2007 Sydney Motorshow.
The Mazda3 MPS Extreme has received engine, suspension and exhaust upgrades that improve the performanceby about 20 % based on the top-selling Sports Pack luxury specification.
The modification includes recalculation to the car’s Powertrain Control Module (PCM). This helps the standard 2.3-litre DISI turbo engine to produce 210kW (281 hp) at 5300rpm and 425Nm of torque at 4400rpm. The modification was done by Mazda Australia Motorsport Manager, Allan Horsley. Other modifications are a free-flowing two-inch exhaust system and a sports muffler
Meanwhile, the suspension system was redesigned by one of Australia’s best suspension tuners, Murray Coote, and it now sits 25mm lower than the standard model, giving the car a more aggressive, sporty stance, responsive and could make up to the new power boost.
