In Fendt's extensive model update in autumn 2025, the 300 Vario was updated to the Gen5 generation. The most significant update was the DynamicPerformance extra power, which released 10 horsepower more power in each model when it was needed, for example, due to the power take-off, compressed air system or air conditioning. The engines were still 4.4-liter Agco Powers. The transmission was the ML75, which enables a top speed of 40 km/h with one range gear.

The output of the hydraulic variable displacement pump was now 110 l/min as standard. For front loader use, a separate central valve is a new feature, which means that oil no longer needs to be taken to the loader from the rear valves. Three electric valve blocks were standard. Apple CarPlay, or the integration of the iPhone into the armrest display, was also new. The same equipment as the larger models was available as an option, namely a heated and laminated windshield and trailer brake assist.

In addition to the basic Power model, the Profi model also had cab suspension, a multifunction joystick and swivelling front mudguards. The Profi+ model had a 12” display, the basic guidance system package and steering acceleration.
