Audi introduced the first Stop & Start system with automatic gearbox
Here is a very promising first world, for those who do not afford a hybrid or electric vehicle and will want all the same do their part in environmental matter. We also have many able to afford an Audi, but this technological approach should encourage other manufacturers to develop too, this innovative technology of his time ...
Recall that the Stop & Start system, close the engine's main feature when the vehicle is immobilized and on again, as soon as it weighs on the accelerator. A very expensive technological approach not, which in some cases allows a saving in fuel ASSESSED between 7 and 12% in urban traffic or reach 17% in circulation called a bumper bumper. The owners of hybrid vehicles know very well, what are the main advantages of benefit from such a technology.
The European approach
In recent years, many Europeans manufacturers imitate the example of Citroen using several of their new models, the Stop & Start technology, but only associated a diesel engine mated to a manual gearbox.
Now, however, the famous manufacturer with the four rings is innovating once again, putting on the European market two versions of its popular model A3, beneficiant the Stop & Start function, but this time coupled to an automatic transmission.
The Audi approach
The selected models of the A3 family are versions 1.4 TFSI engine and a 1.6 TDI. The atmospheric engine developed for the occasion a power of 125 horsepower, while the turbo diesel engine delivers 105 horsepower.
While in America, we dedicate a boundless admiration or almost insignificant to the engine power, europeans on their side know very well that it is the torque that generates the real power is transmitted to the drive wheels. In addition, in the latter, including the German side, we see that the maximum torque is often reached the 1500 tour minutes and is held up beyond the 4000 rpm.
All this, to bring you to discover couples offered by these two engines. For its 1.4 TFSI engine presents a couple of 148 lb-ft (200 Nm) supported between the beaches of 1500 and 4000 rpm, while the 1.6 TDI engine announces a maximum torque of 184 lb-ft (250 Nm) the reached 1500 rpm.
In addition to the Stop & Start system, the new Audi A3 with this technology see also offer a recovery system Energy uses braking and cruising speed. This energy is temporarily stored in the battery during accelerations and redistributed to different electrical systems available to each car.
These figures speak for themselves
According to European data of the manufacturer, the little Audi A3 powered by the 1.4 TFSI engine sees an index of consumption of only 5.3 km li/100 and emits 124 g / km of CO2 in the atmosphere . For its part, the engine 1.6 TDI announces a consumption of 4.2 li/100 km and CO2 emissions limited to 109 g / km.
That figures that are similar to those of some hybrid cars, and remember that these data are those associated car has excellent automatic gearbox S-Tronic dual-clutch six-speed, scored Audi.
Audi A3 Sportback EUROPEENNES Cup and offering technological approach Stop & Start is available from November on different chess cars of the old continent.
Their arrival in America is certainly not planned for the moment. By cons, we are about to receive the model Audi A3 2.0 TDI, a highly anticipated release that could even win the approval of our southern neighbors, usually refractory to this type of engine.
