DRIVING STYLE EVALUATION plays a decisive role in reducing fuel consumption by acting on the human factor. A fuel-efficient driving style delivers real fuel savings of between 5% and 12% - more than any technological solution can achieve. To improve the driver's performance, the system processes the data acquired from the engine, vehicle and GPS using an advanced algorithm (developed by IVECO) and provides two types of feed-back in real time: driving style evaluation and suggestions for reducing fuel consumption.
