Only 2.99 liters of diesel per 100 kilometers (factory specification) uses the Audi A2 1.2 TDI. To reach the target three-liter, Audi's aerodynamics improved the properties of the A2 body in numerous details. For example, the optimal utilization of the air flowing enabled the closure of part of the air intakes at the front, a measure that reduces the air resistance of the Audi A2 1.2 TDI noticeable. The drag coefficient of the A2 1.2 TDI have reduced to 0.25 Cd amazing the Audi engineers. Thus, the small car reaches the best drag coefficient, the previously achieved a production car. Another important element are special tires in size 145/80 R 14 These reduce the Audi A2 1.2 TDI not only the rolling resistance, but also offer aerodynamic advantages. They are narrower than the standard tires the rest of the Audi A2 models and in addition are flow optimized by fine grooves on their flanks. The aerodynamically designed underbody of the A2 has the three-liter version additional panels. Result: The air flow to the underside - one of the biggest aerodynamic potentials in modern cars - is led by aerodynamic point of the three-liter model Audi A2. Turbulence can be avoided this way. The Audi A2 1.2 TDI was the first four-door three-liter car in the world. In this website you will find cheap and economical small car - and new or used.
