The first diesel-electric snow groomer in mountain use worldwide:
the PistenBully 600 E+.

The PistenBully 600 E+ has a six-cylinder diesel engine from Mercedes-Benz; it produces 295 kW (400 hp) from a 12.8-litre cubic capacity. The diesel is combined with electric aggregates: two generators, two drive motors and a tiller motor (each 140 kW/650 volts). The generators convert the mechanical energy produced by the motor into electrical energy and transfer this to the drive system.

The drive technology not only facilitates a 20-% reduction in both NOx and CO2, but also a 20-% drop in fuel consumption, which means the associated operating costs also fall by a dramatic 20 %. The fact that 99 % less soot particles are released into the air is an additional happy bonus.

The saving effect is achieved through three factors. Firstly: the drive motors produce energy on the downrides, which drives the tiller. Secondly: the diesel motor always operates in the optimum speed range. And thirdly: the electric power transmission is more effective than the hydraulic.

And yet with all this the PistenBully 600 E+ remains a
100-% genuine PistenBully.
