The TFSI engines in the Audi A4 Saloon. Powerful and advanced.
All the petrol engines are equipped with TFSI, a consequent combination of economical direct injection and turbocharging. As standard, all engines are equipped with the start-stop system, as a result of which they are among the most fuel-efficient power units of their class. The A4 models use TFSI technology. And the remarkable thing about it is it combines the advantages of FSI with a supercharger, which ensures even better power delivery. All TFSI engine features as standard a start-stop system and of course fulfil the EU5 emission standard. The 1.8 TFSI has 125 kW of power and a maximum torque of 320 Nm and is one of the most fuel-efficient engines of its class. The Audi valvelift system lowers consumption and due to an intelligent thermal management the engine reaches its operating temperature faster. At the same time, it directs heat to the interior which
The TDI engines in the Audi A4 Saloon. Powerful and efficient.
The 2.0 L TDI engines are provided with the common rail injection technology. As standard, all engines are equipped with recuperation, as a result of which they are among the most fuel-efficient power units of their class. One in every two Audi cars sold today is a diesel. What we take for granted now was quite a sensation a mere 20 years ago: Audi revolutionised the market with the first 2.0 litre TDI engine. Since then, developments such as common rail technology with its refined and precise fuel distribution have made TDI even more efficient. Consequently, since the first TDI, the engines have become more economical, whilst specific output has increased. So it was only logical that a diesel car should then enter the world of motorsport. And successfully too: in 2006, Audi was the first car maker to win the Le Mans 24 Hours with a diesel-powered race car, the Audi R10 TDI - and then went on to repeat this victory
