TÜMOSAN Pusat 4×4: tactical vehicle, in-house powertrain
Quick answer: The Pusat 4×4 is a light-class tactical wheeled armoured vehicle developed by TÜMOSAN. It was unveiled at the IDEF 2017 exhibition. The vehicle’s central claim is that all of its main subsystems — from the engine and gearbox to the drivetrain, suspension and electronic control units — are designed and built by TÜMOSAN itself; on that basis the company reports a local-content ratio of roughly 100 percent. Open sources cite a 1+8 crew capacity, BR7-level ballistic protection and a top speed of 110 km/h. No confirmed order or inventory entry for the vehicle has been publicly announced.
What is the Pusat, and what need does it address?
The Pusat is a 4×4-class tactical vehicle designed for reconnaissance, surveillance, personnel transport and internal security missions. In Turkey, vehicles such as the Otokar Cobra II, BMC Vuran and Nurol Ejder Yalçın are built in the same class. TÜMOSAN’s differentiation strategy comes not from vehicle integration but from powerpack manufacturing: the TMSN X series military diesel engines and TÜMOSAN gearboxes are the vehicle’s main in-house components. The company asserts that the indigenous powerpack delivers fuel savings of up to 30 percent; this figure has not been verified by independent testing.
Technical specifications (open source)
The values below were compiled from data published in the defense press (DefenceTurk); TÜMOSAN’s official website does not carry a detailed technical datasheet.
| Specification | Value |
|---|---|
| Length / width / height | 5,560 / 2,500 / 2,370 mm |
| Crew | 1+8 |
| Payload | 2.5 tonnes |
| Ballistic protection | BR7 level; mine protection and mine-resistant seats |
| Engine | TMSN X 5.5 (some sources also cite the TMSN 5.4), turbo diesel |
| Gearbox | TÜMOSAN 8+1 synchromesh automatic |
| Top speed / range | 110 km/h / 700 km |
| Gradient / trench / fording | 70 percent / 0.9 m / 75 cm |
Engine information differs between sources: DefenceTurk’s datasheet gives the TMSN X 5.5, while the company’s SAHA EXPO 2024 announcement states that the Pusat uses the TMSN 5.4 engine. It is plausible that different engines were trialed in different prototypes; the company has not issued a detailed clarification.
Pusat Hybrid: the diesel-electric variant
TÜMOSAN displayed a hybrid-drive version of the Pusat at the IDEF’21 exhibition in August 2021. Press coverage described the vehicle as Turkey’s first hybrid-drive military land vehicle prototype. The hybrid architecture uses the company’s own Hybrid Power Distribution Unit (HGDÜ) and Hybrid Vehicle Control Unit (HAKÜ); both units are also listed as standalone products in the SSB 2026 catalog. The electronic subsystems are covered in detail in the drivetrain and vehicle electronics file. The series-production status of the hybrid version has not been officially disclosed.
Variants and modularity
The company states that the Pusat’s modular structure allows it to be adapted to different requirements at short notice and that derivatives such as an armoured ambulance and a pickup can be developed. Open sources report an ability to integrate different weapon systems; there is, however, no confirmed contract for the integration of a remote-controlled weapon station. Given that the Otokar Cobra II and Nurol Ejder Yalçın in the same class have production and export references running into the thousands in the Turkish market, the Pusat’s competitive position rests largely on the local-content argument for its powerpack.
Program status: on display, no order announced
Since its 2017 debut, the Pusat has been shown regularly at the IDEF and SAHA EXPO exhibitions; most recently it appeared on the IDEF’25 stand held on July 22-27, 2025. Albayrak Group’s IDEF’25 announcement stated that the vehicle had passed its ballistic tests. To date, however, no confirmed order from the Turkish Armed Forces, the General Directorate of Security or a foreign user has been announced. TÜMOSAN’s concrete contract in the vehicle class concerns engines rather than vehicles: under the ÖMTTZA contract signed with FNSS, TÜMOSAN engines are being supplied for 100 armoured vehicles; details are in the military engine programs file. A comparison of the Pusat with its foreign counterparts can be read in the Pusat-JLTV comparison.
Frequently asked questions
Has the Pusat 4×4 entered service?
Not officially disclosed. The vehicle continues to be shown at exhibitions; publicly available sources record no confirmed order or delivery.
What is the Pusat’s protection level?
Open sources cite BR7-level ballistic protection and mine protection. The modular armour design is reported to allow the protection level to be configured to the mission.
How many people does the Pusat carry?
According to open-source data, it has a 1+8 crew capacity and a 2.5-tonne payload.
When was the Pusat Hybrid unveiled?
It was displayed at the IDEF’21 exhibition in August 2021. The press covered it as Turkey’s first hybrid military land vehicle prototype.
Which engine powers the Pusat?
Sources differ: the DefenceTurk datasheet says TMSN X 5.5, while the company’s SAHA EXPO 2024 announcement says TMSN 5.4. Both engines belong to TÜMOSAN’s own military diesel family.
Sources and verification note
Technical values come from the defense press; the company has not published an official datasheet. The absence of any official statement on orders or inventory status holds as of August 13, 2026. Accessed: August 13, 2026.
