BorgWarner’s twin scroll turbochargers, featuring enhanced high temperature performance thanks to the use of sophisticated steel alloys, are being delivered to the BMW Group for its new 3.0-liter inline six-cylinder gasoline engine. Used across a wide range of BMW passenger cars, the engine has two performance options – medium and high – and delivers 250 to 280 kW of power and 500 to 550 Nm of torque.
“Twin scroll technology produces results similar to twin turbo applications but in a smaller package with reduced weight and cost. We are delighted to have worked with BMW to develop and deliver these latest designs, which use advanced high-temperature alloys and casting technologies that allow our customer to develop a low-emissions engine that combines comfortable driving with excellent performance and an agile response at low engine speeds. With this project successfully completed a large number of BMW passenger cars are expected to be equipped with BorgWarner turbochargers into the future,” said Joe Fadool, President and General Manager, BorgWarner Emissions, Thermal and Turbo Systems.
Compared with a single scroll turbocharger, a twin scroll design recovers more energy from the exhaust gases, minimises parasitic back losses and improves responsiveness at low engine speeds.
