TFSI®

Audi was the first manufacturer in the world to combine petrol direct injection with turbocharging in large-scale car production. The success story of the 2.0 TFSI was launched in summer 2004 when it debuted in the Audi A3 Sportback.

The combination of petrol direct injection and turbocharging appreciably improves efficiency and thus fuel economy. The result: more power and more dynamism with lower fuel consumption.

Compared with conventional naturally aspirated V6 engines, a turbocharged direct-injection four-cylinder engine delivering the same performance uses 10 to 15 percent less fuel.

FSI technology and turbocharging make such an excellent combination because the evaporation of fuel directly within the combustion chamber removes heat from the intake air. This allows higher compression, significantly improving engine efficiency. It also resolves an old problem in all turbocharged engines – a high tendency to knock at high boost levels.

The integrated turbocharger/exhaust manifold module ensures optimum turbine efficiency, resulting in excellent utilisation of the exhaust gas energy. It is thus possible to achieve both a high power output and optimum responsiveness. This ultimately helps to effectively reduce fuel consumption and exhaust emissions.

The second generation of 2.0 l TFSI engines, which was introduced in the Audi A4, A5 and Audi Q5 in 2008, featured for the first time valve lift control in the form of the Audi valvelift system on the exhaust side. The result was significantly improved torque with better low-end torque and a more effective dynamic torque build-up. Alongside performance improvements, these optimisations were also translated into longer gear ratios, bringing about a further reduction in fuel consumption.

The combination of petrol direct injection and a mechanical turbocharging module makes the 3.0 l V6 engine, fitted in selected Audi models, a compact power plant with an early maximum torque of 400 Nm sustained over a wide power range – with moderate fuel consumption. With its very spontaneous response and an extraordinary power flow across the entire rpm range, the six-cylinder unit also permits a particularly dynamic driving style.

By bringing together turbocharging and petrol direct injection, TFSI unlocks a superior potential: more power and dynamism with lower fuel consumption.
