Audi is the first manufacturer to combine the start-stop function with an automatic transmission in a diesel engine. So far, this has only been available in the Porsche Panamera with a petrol engine.
The future brand companion has shown it. In the recently launched Porsche Panamera, a start-stop function works together with a dual clutch transmission. VW subsidiary Audi is now also installing this combination in the A3 1.6 TDI with 77 kW / 105 PS and the 1.4 TFSI with 92 kW / 125 PS.
Recuperation system on board
The start-stop system switches off the engine as soon as the vehicle has come to a standstill and the driver continues to press the brake pedal. It starts it again when you release the brake pedal. As a result, the diesel should only consume 4.2 liters per 100 kilometers, which corresponds to CO2 emissions of 109 grams per kilometer. The gasoline engine should be content with 5.3 liters and thus emit 124 grams per kilometer.
The recuperation system also helps to save fuel, thanks to intelligent control of the generator in braking and coasting phases, which recovers energy that is temporarily stored in the battery. During the subsequent acceleration, it is fed back into the vehicle electrical system and the generator is relieved.
Audi will start selling the A3 1.6 TDI and A3 1.4 TFSI in both the three-door and the Sportback in November 2009. The prices for the 1.4 TFSI remain unchanged at 23,700 euros (3-door) and 24,600 euros (Sportback). The new 1.6 TDI with S tronic starts at 25,500 euros in the 3-door and 26,400 euros in the Sportback. (AG)
