The roadster has gained a host of safety kit to ensure it can remain on sale as new GSR2 safety regulations come into force.
These include lane keeping assistance, speed limit warning and traffic sign recognition systems.
It also introduces a series of mechanical updates, including a new limited-slip differential for range-topping 2.0-litre cars with a manual gearbox. This differential features different cam angles on its acceleration and deceleration sides, with a stronger setting on the latter to increase stability through bends.
In addition, there is a new track-focused setting for the stability control system, which is intended to strike a balance between dynamism and security for first-time track drivers.
The electric power steering settings have also been revised to reduce steering rack friction and provide a “more natural and fluid” response, Mazda said.
The engine line-up is unchanged, comprising two naturally aspirated four-pots: a 1.5-litre unit outputting 130bhp and 112lb ft, and a 2.0-litre powerplant with 181bhp and 151lb ft.
However, the accelerator pedal has been fettled to deliver quicker, more accurate responses from each engine.
Inside, the updated MX-5 receives a larger, 8.8in infotainment touchscreen and USB-C ports have been added to the phone cubbyhole on the centre console.
