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.

    Xerox’s David Cummins talks to Colin Sowman about the lessons for city authorities from its survey of younger peoples’ attitude to transport. There can be no better way to get a handle on the future of transport demand than to ask the younger generation about how they view and consume today’s transport. Sociologists have called this group Generation Z – those born between 1995 and 2007 – which will make up 40% of all US consumers by 2020.

    The European Commission is placing too much emphasis on the use of demand management, according to the FIA. Here, Wil Botman, Director-General of the FIA's European Bureau, explains why. Towards the end of last year, the European Bureau of the Fédération Internationale de l'Automobile (FIA) released a statement which criticised the European Commission's (EC's) approach to urban traffic congestion following the adoption of the Action Plan on Urban Mobility. In particular, the FIA voiced concerns over what it

    German manufacturer Continental says its Ultrasonic Height and Pressure Sensor (UHPS) can adjust the height of commercial vehicles electronically to improve the efficiency of urban buses. The company says UHPS allows drivers to control the air springs when lowering one side of the bus at bus stops - rather than having to let the air out from the spring completely. UHPS uses ultrasound to measure the height and pressure in the air spring and sends the value to the electronic control unit, which automatica
