FNSS released a video teasing a test where the Kaplan AFV’s hybrid powerpack demonstrator variant was pitted against the in-service Kaplan STA ATGM vehicle.
The test is seen to involve the two externally identical vehicles starting up and accelerating from rest, with the key difference being that Kaplan Hybrid uses a diesel-electric powerpack.
The IDEF’25 promotion in the video suggests that FNSS will be displaying the full test footage during the exhibition in its booth.
FNSS is working on hybrid propulsion for its vehicles to bring not only more driving performance but also improve low observability through reducing the heat and acoustic signatures.
Kaplan Hybrid
Kaplan Hybrid is a technology demonstrator based on Kaplan 10 AFV, which also forms the basis for Kaplan STA ATGM vehicle used by the Turkish Armed Forces.
The vehicle’s powerpack consists of a generator engine with a power output of 400 hp and two electric engines totalling 397 hp in continuous and 617 hp in peak output. With a power/weight ratio between 22-35 hp/tonnes (Depending on continuous or peak power), the vehicle can accelerate to 32 km/h from rest under six seconds. For comparison, Kaplan 10’s ratio is 21 hp/tonnes.
In addition to this, the hybrid powerpack has a silent mode that can run for 14 to 48 hours, depending on the use of an air conditioner.
