The SILENT Cruiser is provided with highly efficient solar cells and a powerful lithium-ion battery bank, in which the produced energy is stored. For the unlikely event of a longer period of time without sunshine, or an emergency on board, a diesel fueled range extender is installed. The range extender charges the batteries automatically, which makes you absolutely independent from the weather. As soon as the sky opens back up the solar panels continue generating cost free energy for you. With the SILENT Cruiser you can drive 24/7 without anything coming from the motor – emission or noise!
