| | If you thought Ferrari were only into gas guzzling exotics, you were wrong. Ferrari has made a patent application for a clever four-wheel drive hybrid system, which could be fitted to both its front- and rear-engined models. However, some of the proposals see the wheels driven by a conventional differential and axles and in the others, small, in-wheel, electric motors will be used to drive the wheels. Ferrari says that this kind of part time 4x4 system is not only less complex, but lighter and less troubled by frictional losses. It also means all-out performance is not permanently blunted because the engine does not have to drive all four wheels all of the time. According to application, the four-wheel drive that can be engaged enables the driver of the automobile to decide whether to use the rear drive or the four-wheel drive; in this way, the driver can use the rear drive in optimal conditions of adherence and can use the four- wheel drive in poor conditions of adherence. Ferrari believes a system such as this could provide the advantages of all-wheel drive while keeping the weight low and allowing the driver to choose standard rear-wheel drive when desirable. Of course, depending on the on-board batteries and electronics used in such a system, the car could potentially be powered solely on electricity under certain circumstances, reducing fuel consumption and lowering overall emissions. |
