It's only been a couple of years since Mazda rolled out the latest ND-generation MX-5 Miata, so we'd expect it to stick around for a while before it'll need replacement.
That won't stop the Japanese automaker from rolling out incremental updates, though, like it has today at the Tokyo Motor Show, where it was easily overshadowed by the unveilings of the Kai and Vision Coupe concepts.
For 2018, Mazda is adjusting the exterior color choices. The soft-top version is also being offered with a special package including a dark red fabric roof, Nappa leather, and black BBS alloys. Meanwhile the Retractable Fastback version gains an optional contrasting black hardtop.
Mazda's also added more sound insulation, more readable gauges, and heated cloth seats. Features like stop/start and brake energy recuperation are also now part of the update across the range, and there are adaptive LED headlamps available, too.
At present, these updates are being rolled out in the Japanese Domestic Market, where the model is known simply as the Mazda Roadster. Expect some (if not all) of the new features to reach other markets in the coming months as well.
