TDI – and the most fuel-efficient Audi ever
A dedication to pioneering technology has brought Audi great expertise in turbocharged diesel engines. All Audi TDI engines are equipped with common rail technology to achieve smooth, efficient and quiet combustion. Diesel fuel related emissions are significantly reduced thanks to a diesel particulate filter, fitted as standard, which filters out almost all soot particles contained in the exhaust gas.
The Audi A1 1.6 TDI has a variable turbine vane geometry turbocharger to help produce higher torque and stronger pulling power. And sophisticated air-flow control also contributes to the engine’s capabilities while simultaneously reducing nitrogen oxide emissions.
