When Mazda unveiled its completely redesigned MX-5 Miata last summer, many details were left out. Hell, the Japanese automaker didn't even reveal which engine the US market will receive. However, we've now confirmed that the US-spec fourth-gen MX-5 will be powered by a 2.0-liter SkyActiv inline-four paired to a six-speed manual. Other markets will be offered an optional and smaller 1.5-liter inline-four. Something else to note: Mazda never revealed any of the roadsters exact dimensions.

Today, however, we've also learned that the new car is 3.2-inches shorter and an inch narrower. Its wheelbase measures in at 91.1 inches - 0.6-inches shorter than before. Weight? An exact figure still hasn't been given, but Mazda already stated that it's shaved off roughly 220 lbs. You can do the math from here. The US-spec model also features a double wishbone front suspension and a multi-link rear suspension, electric power assisted steering, and ventilated disc brakes on the front axle.
