This is a very nice looking convertible! I did some power to weight ratio calcs and the FR-S still comes out ahead slightly. The FR-S is at 13.8 lbs per horsepower,whereas the 2016 MX-5 will have 14.2 lbs per hp. These calcs are based on curb weights of 2205 for the Mazda and 2753 for the FR-S, with 155 and 200 bhp, respectively. It should be noted that the R&T article does not give the HP figure of the 1.5 liter engine, but even allowing for the lowest possible curb weight (which will be too low for the non-Japan version) and the higher powered engine (the 2.0 l) the FR-S still wins in the PtW department.

Obviously, the MX-5 comes out well ahead on torque relative to its mass. It will come down to the transmission and differential gearing to see which car will have better acceleration.
