Excellent fuel consumption & less emissions with the Mazda3


This efficient car combines an exhilarating driving experience and exceptional fuel economy, with low CO2 emissions from just 107 g/km1. This impressive environmental performance is achieved with our pioneering technologies including i-stop and our advanced SKYACTIV Technology.


Another contributor to the impressive fuel efficiency is the car’s leading aerodynamic performance. This is aided by the active air-shutter* in front of the radiator, which opens and closes automatically with driving conditions, reducing the car’s drag and improving the environmental performance. This new-to-Mazda feature contributes to the stable and stress-free driving experience you’ll enjoy.

i-ELOOP A pioneering way to capture and release energy for this efficient car

i-ELOOP is a regenerative braking system that recovers lost kinetic energy during deceleration and stores this as electricity in a quick charging capacitor. i-ELOOP is the perfect companion for i-stop, since there is no need to revert to battery power, even when Mazda’s idle-stop system has put the engine in standby (at traffic lights, for example). During stop-and-go city driving, charging often resumes before the capacitor is fully discharged. As a result, i-ELOOP can produce most if not all of a vehicle’s electricity needs, meaning the engine does not need to divert power to charge the battery, improving engine efficiency and fuel economy.

i-stop technology Better fuel efficiency from an efficient car with no compromise

Inspired by cyclists, our i-stop system positions the pistons perfectly to quickly restart the engine.

i-stop improves your car’s environmental performance by switching off your engine when you’re idling in traffic. You’ll hardly notice this happen because i-stop restarts your engine more quickly and smoothly than most stop-start systems. So your engine’s ready to go as soon as you want it. i-stop is available with both our automatic and manual transmissions.

The winner of several technology awards, this is the world’s only start-stop system that uses combustion energy to restart. Just one more way that we defy convention.
