Mazda has unveiled the all-new, restyled, fourth-gen MX-5 Miata Roadster ahead of its 2015 rollout. The car weighs 100kg less than the outgoing model and says it has the lowest-ever center of gravity in the series.

There wasn't much mechanical details of it, only confirming its SKYACTIV-G petrol engines and the first rear-wheel drive version of the SKYACTIV-Chassis. The engines will be hooked up to a 6-speed manual driving the rear wheels.

More to come. Check out the gallery for a few more shots.
