"As the first to combine gasoline direct injection with turbocharging in volume production years ago, Audi is once again setting new standards in performance and driving excitement," Tim Manganello, BorgWarner CEO said in a release. "BorgWarner is pleased to contribute our advanced technologies to these powerful new engines."
BorgWarner worked for the integration of the technology with the engineers from Audi's quattro. The aim was to develop a turbocharger with special geometry and low weight. The two teams accomplished this by adapting the manifold and turbine cross-sections.
High efficiency was obtained by using a relatively large compressor impeller. The timing drive system manages the increased loads caused by turbocharged engines.
The collaboration between the two began with the work on the 2.0l four cylinder diesel engine from the TT range. It develops 170 horsepower thanks to BorgWarner's third-generation variable turbine geometry (VTG) turbocharging technology. This unit consumes 5.5 liters/100 km (42.8 mpg).
BorgWarner's turbochargers will also be used by Chinese car manufacturer First Automotive Works (FAW). The Chinese will equip its models with turbochargers in 2010, with the newly-developed 1.3-liter and 2.0-liter liter gasoline engines to be the first to get turbocharged.
