Mazda revealed two extreme lightweight design concepts for the MX-5 Miata at the 2015 SEMA Show - the MX-5 Spyder and MX-5 Speedster. The Spyder accentuates the open-air experience with a bikini top and weighs 2,301 lbs, while the Speedster pares the design back to the essentials for an unadulterated driving experience and weighs 250 lbs less than the Spyder at 2,080 lbs. Both concepts showcase Mazda's dedication to lightweight performance and focus on the core strengths of the MX-5.
