Progress Through Efficiency : The New Way Forward
First in the premium segment in SA: Audi of South Africa introduces start/stop models at no extra cost.
Audi is synonymous with being the leader in progressive technology and pioneering new innovations. The 21st century brings in a new era of challenges, predominantly the challenge to become more environmentally conscious and reduce CO2 emissions. One of our most important tasks in the future is to increase efficiency even further.
Energy management also offers huge potential for efficiency – for the air conditioning system, for example, energy recovery and termo management. The intelligent assistance systems such as the on-board computer with efficiency program also offer valuable support to the driver.
Last but not least, the new Start/Stop system which switches off the engine when the vehicle is stationery is now being introduced locally by Audi in a number of its models – a first for the South African premium segment.
2009 also saw Audi South Africa making significant strides by further enhancing the efficiency of the Audi models. This is clearly highlighted by the transition to Euro 4 & 5 emission levels of all cars in May.
The Start/Stop system
The Start/stop system helps to save fuel and and reduce CO2 emissions, and realises its efficiency potential in urban traffic especially.
Simply put, the engine switches off automatically when you stop the car at, for example, a traffic light …and starts up again automatically when you are ready to drive off.
When the vehicle stops, the engine is switched off. The vehicle’s electrical system is supplied with electricity from rapid power storage devices called supercaps. As soon as the driver presses down the clutch, the engine is started. By the time the clutch pedal is released, the engine has reached idling speed.
An intelligent engine management system ensures short engine starting times and eliminates all negative effects of switching off and starting the engine with regards to exhaust emissions.
