Mazda Motor Corp. unveiled a new version of its iconic MX-5 Miata sports car Thursday for the first time in nine years, counting on the model to help sustain rising sales.

Mazda showed the car at an event to mark the Miata's 25th anniversary in Japan, the U.S. and Spain.

The fourth-generation model is the most compact so far and more than 100 kg lighter than its predecessor, Mazda said. Sales will start globally next year.
