Since 1983, Bremach produced its most famous GR series (4×4). The range included unified multi-purpose all-wheel drive GR35 and GR45 models with a gross weight of 3.5-4.5 tons and a 4-cylinder 2.5-liter IVECO diesel engine rated at 75 hp (turbocharged – 103 hp). The transmission consisted of a main 5-speed gearbox and additional transfer case, which provide 20 forward and 10 reverse gears and a maximum speed of 115 km / h (minimum – 2.5 km / h).
The frame is assembled from longitudinal tubes with crossbars. The trucks have front disc brakes and leaf springs suspension. To drive external equipment hydraulic pumps and several rear, front or side power take-off shafts can be installed.
There were several variants of the base models: GR35V and 45V heavy-duty construction chassis, the Trekking all-terrain series with ground clearance increased to 240 mm, and the Montes with closed cargo and utility bodies.
