As Stinger missile. I heard it is faster than Stinger.
According to TurDef article it is faster than Stinger.

SUNGUR is a new generation MANPADS fitted with IIR guidance. The missile was first fired from a BMC VURAN 4x4 tactical wheeled vehicle’s turreted 2x2 launcher. SUNGUR was later tested in shoulder-fired configuration, shooting down a high-speed target drone.
The missile’s two-stage rocket motor allows for increased terminal performance with a range of up to 8 km.
SUNGUR surpasses the current in-service FIM-92 Stinger missiles in terms of guidance and range. The difference between the two missiles’ guidance is that Stinger missiles lock on the heat while IIR seekers, mostly used on modern air-to-air missiles, track the image of the target in addition to heat, increasing the resistance against countermeasures.
Following the land vehicle integration and shoulder-fired configurations, SUNGUR will also be integrated on Baykar’s Bayraktar TB2, AKINCI and Bayraktar TB3 armed UAVs. AKINCI was displayed with two-tube launchers, but Bayraktar TB3 was displayed with a single-tube launcher during UMEX 2024.
Unquote.
As both missiles‘ specs are similar in given range, altitude and speed values, you are correct to question it.
Stinger missile rotates around its axis to achieve lock on target. It has an effective operational envelope that is actually less than Sungur’s.
Sungur has a much better and more developed seeker head. It has an overall range and altitude advantage over Stinger in terms of number of kill ratios per the number of firings for the same distance and altitude. (In short; Sungur over a given number firings at a distance of 8 km and 4km altitude will have more success than a Stinger).
Also keep in mind that Sungur is ours and we are not very forthcoming when it comes to specification of weapons. Hence, it is totally feasible to expect that true values are somewhat not reflected in the given ones.
