Audi Introduces Stop-Start and Energy Recovery Systems for 2

Post by LhYnxz on Sun May 10, 2009 11:15 am



Audi will introduce an onboard computer
system fitted with something called the efficiency program as well as
the familiar start-stop system. These technologies are part of the
solutions that Audi will use to cut down fuel consumption levels by 20%
on 2007 levels by the year 2012.
Additionally the energy recovery system is installed. It is already
available as standard specification in a number of Audi models. What it
does is to feed energy back into the vehicle's electrical system during deceleration in order to further improve efficiency.
The start-stop system works by shutting down the engine when the car
comes to a halt. As the driver pushes the clutch the engine starts
again. The system can be switched off manually at any time by pressing
a button. Audi estimates that in the regular Euro cycle fuel
consumption is lowered by 0.2 litres per 100km. C02 emissions are
consequently reduced by 5 g/km. Cars that will receive the system first
are the manual versions of the A3 1.4 TFSI, the A4 and A5 with
2.0-litre engines.
The onboard computer with the efficiency programme comes with
consumption-related data that is shown on the centre display. Drivers
are then given recommendations for more efficient driving, depending on
their style and the prevailing road situation. There is even a
gearshift indicator to prompt drivers to change gears at the most ideal
gear times. Also, systems that require extra energy to operate, like
the air conditioning and seat warmers, are identified by the efficiency
programme.
