Based on the current MX-5, the Spyder follows in the footsteps of 2009's MX-5 Superlight concept, adding a new streamlined bumper design and a canvas roof that stretches across the rear deck.
The exterior tweaks are rounded out by new skirts and lips, with the whole package sitting low on a set of large light-alloy wheels and a performance braking package.
No technical details have been revealed for the MX-5 Spyder, although Mazda describes the concept as "a new, more aggressive look for the world's favorite convertible"; so don't expect much to change under the hood.
Mazda has revealed little about the new concept, based on the current model, but the carmaker promises "one of our most powerful turbocharged engines in our lightest platform".
On the styling front, the Turbo2 sits low on big 10-spoke alloy wheels and rubber-band tyres, with new skirts and a high-mounted wing at the rear.
Watch for more details for both concepts to surface in the coming weeks.
