Audi A4 TDI concept represents e.
The strategy of small steps: Unlike in the past, when the VW group eco-offensive with elaborately constructed - and consequently expensive - savings as mobile 3L Lupo or Audi A2 1.2 TDI denied pursued the car giant is now a different strategy: Instead of using exotic lightweight materials will be smaller but now, thanks to crucial improvements to the fuel arrive objective. With the BlueMotion models are the parent Wolfsburg from the direction in which now include the Ingolstadt Audi subsidiary marches. At the Paris Motor Show, 4 to 19 October 2008 unveiled the Audi A4 TDI e Concept, a consumption-optimized version of the middle class sedan for pure CO2 conscience.
Flow Optimized

Just like the BlueMotion models from VW’s Audi also begins to-finish body. A fresh grille with fewer openings, a moderate lowering of the body, a smooth underbody and a demolition edge on the lower trunk lid cw value from 0.27 to 0.25. The 2.0-liter TDI under the bonnet was also slightly revised: Revised springs at the inlet valves and a new thermal management are intended to direct more environmentally friendly leave act.
Not slower than the series
The result can be in this class is not bad: Audi is the concept of e a total consumption of 3.99 liters per 100 km and a CO2 emissions by a modest 105 grams per kilometer to. The performance data are compared to the 2.0 TDI civilian incidentally unchanged: 120 hp and 290 Newton-meters ensure both here and there for jacking and accelerate both versions in 10.7 seconds at 100 cases. That the concept E 206 instead of 205 km / h top running well testifies to the effectiveness of the aerodynamic revision as a look at the consumption levels of the series A4: The swallows 5.1 liters per 100 kilometers and 134 grams pustet this greenhouse gas into the atmosphere .
At the traffic lights: engine
Another popular measure savings are based on the eco-A4 assembled, rollwiderstandsoptimierten tires. A lack of driving dynamics, however, must therefore nobody fear: gums with 225/45 R17 format is the Audi tires with exactly the same size as a current Golf GTI on the road. In addition, the Ingolstadt an energy recovery system under the sheet, the electricity generated during braking and stores. Also on board is a start-stop system, the engine stopped off. In addition, more tricks for even greater efficiency: How to clean, the A4 to intelligently regulated ancillary equipment (such as air conditioning), a gearbox from extraleichtem magnesium or an eco-training program in the central display, the chauffeur to drive indicating uneconomical.
