Well, Mazda has taken the wraps off its mysterious engine choices at the 2014 Paris Auto Show. While global versions of the famous two-seat roadster will see a 1.5L 4-cylinder SKYACYIV-G engine, the US version of the 2016 Mazda MX-5 will be powered by a 2.0L SKYACTIV-G unit.
Mazda is getting quite good at dangling pockets of information then keeping the good bits hidden, and they continue to do so by keeping the output numbers from the ever-eager public. Horsepower and torque numbers were not announced. However, considering the same 2.0L SKYACTIV-G engine is found in the Mazda3 (which offers up 155 hp) it's safe to assume the MX-5 version of that engine will pump out at least a little bit more than that, perhaps in the 170 hp range (fingers crossed) -- slightly more than the current-generation MX-5.
