Turbochargers and timing drive systems for the Audi TT RS and its new 2.5l five cylinder inline gasoline engine will be provided by BorgWarner, which is known for specializing in advanced turbocharger technology. With this unit, the TT RS will be able to maintain fuel consumption at about 25.5 mpg (9.2 liters/100 km) and will be able to accelerate from 0-60 in 4.6 seconds.
In a release, Tim Manganello, BorgWarner CEO, said that several years ago, Audi was the first to combine gasoline direct injection with turbocharging in volume production and that today, Audi is again setting new standards in performance and driving.
To integrate BorgWarner's advanced technologies with Audi's powerful new engines, BorgWarner worked with the engineers from Audi's quattro. Their target was to develop a turbocharger with special geometry and low weight. They achieved this by adapting the manifold and turbine cross-sections. To obtain high efficiency, a relatively large compressor impeller was utilized. The timing drive system manages the increased loads caused by turbocharged engines.
Their collaboration actually began with the work on the 2.0l four cylinder diesel engine from the TT range. Due to BorgWarner's third-generation variable turbine geometry (VTG) turbocharging technology, the model develops 170 horsepower.
This unit consumes 5.5 liters/100 km (42.8 mpg). Meanwhile, BorgWarner's turbochargers will also be used by Chinese car manufacturer First Automotive Works (FAW). In 2010, FAW will equip its models with turbochargers, with the newly-developed 1.3-liter and 2.0-liter liter gasoline engines to be the first to get turbocharged.
