The system automatically switches off the engine upon engaging neutral or whenever the car is stationary for more than a few seconds and restarts the engine when the driver simply depresses the clutch.
"The all-new Mazda3 2.0 Sport with our exciting ‘i-stop’ technology uniquely delivers both performance and cost savings to fleets, company car and individual drivers," said Peter Allibon, Mazda Fleet and Remarketing Director.
"In recent times, a 2.0 Sport petrol model may not have been the obvious first choice for a city-bound company car driver.
"However, the introduction of our highly efficient i-stop technology means that our latest model may change all that. The new Mazda 3 2.0 Sport with i-stop will be the right choice for city drivers who still want to experience power and performance from their company car out on the open roads.
"Indeed, the Mazda3 2.0 Sport with i-stop makes cost-effective performance driving accessible to a totally new group of drivers.
The revised DISI engine is remarkably sophisticated with sequential valve timing and a variable induction system to ensure powerful torque throughout the rev range.
For employees who regularly experience stop-start motoring in urban environments, our fuel-sipping i-stop technology mated to this 2.0-litre engine is the sensible money-saving choice."
Mazda claims a 16 per cent fuel saving on models fitted with i-stop technology as well as a reduction in CO2 output of 19 per cent.
There's no word yet on when the technology will be available on Australian Mazda3 models.
