The rumors of Mazda developing a more powerful MX-5 Miata were true. Japan’s Car Watch had the opportunity to drive a prototype for the updated roadster, and the magazine divulged all the details. The 2.0-liter four-cylinder now packs 182 horsepower at 7,000 rpm rather than 155 hp at 6,00 rpm in current form. Torque grows a little bit to 151 pound-feet from 148 pound-feet in the existing model.
To achieve such a significant power bump, Mazda overhauls the powertrain. New pistons are 0,95 ounces lighter, and the connecting rods weigh 1,4 ounces less. To breathe better, the Miata’s engine has a larger diameter throttle body, bigger exhaust valves, and wider exhaust piping. These improvements let the redline rise to 7,500 rpm from 6,800 rpm.
