948 General Motors has revealed a new innovation behind the front grill of its 1960 Chevrolet Cruze Eco model where an automatic air shutter system allows the car to change shape and cut through the air more smoothly.

The air shutter system uses sensors to feel and sense wind and temperature conditions. The sensors are married to electric motors that open and close the shutters automatically. With the shutters closed at high speeds, wind drag is reduced. At lower speeds, the shutters open to maximise engine-cooling air flow. Chevrolet says the air shutter system contributes nearly half a mile per gallon in combined city and highway driving.

The cooling systems for all GM vehicles are designed for the worst-case scenario, which is pulling a trailer up a grade in Death Valley. The shutter allows them to significantly improve fuel economy, while still providing the cooling needed in that extreme case.

    The adaptation of machine vision to transport applications continues apace. That the machine vision industry is taking traffic installations seriously is evident by the amount of hardware and software products tailor-made for ITS applications that are now available on the market. A good example comes from US-based Gridsmart Technologies which has developed a single wire fisheye camera that provides a horizon to horizon view for use at intersections. Not only does the single camera replace four or more in a
