Due in 300 units, the folding hard-top variant comes exclusively in Eternal Blue Mica paint and uses the 158bhp version of Mazda’s atmospheric 2.0-litre engine that sends power rearwards through a standard-fit limited-slip differential.
No changes have been made to the car’s powertrain, so it can hit 62mph in 7.3sec and has a top speed of 133mph.
The new variant gets its name from the black trim added to the exterior. It includes a rear spoiler and mirror covers finished in the shade. The wheels are gunmetal-coloured, while there are leather seats inside.
Since this car builds on the spec of SE-L Nav trim, the Sport Black edition also has rain-sensing wipers, rear parking sensors and automatic headlights, along with climate control, cruise control, a touchscreen MZD infotainment system and Bluetooth connectivity.
The new variant will make its public debut on 29 April at the MX-5 Owners Club Spring Rally at Goodwood Motor Circuit. It will go on sale on 28 May, priced from £25,695.
This makes the Sport Black edition £100 more expensive than the recently launched MX-5 Z Sport. That car, based on the soft-top version, is also limited to 300 units and gets a raft of additional features including a standard-fit red roof and leather seats.
