After the success of the 4-cylinder 1.9-liter TDI and SDI direct injection diesel engines in the Passet, Jetta and Polo classes, a new 3-cylinder TDI has been developed for use in the 'Lupo 3L', a compact car with a fuel consumption of 3 liter per 100 km. A new injection system with unit injectors, together with a fully electronically controlled engine management system featuring drive-by-wire-technology, a turbocharger with variable turbine geometry and a fully automated mechanical gearbox and clutch, for the first time ensures the potential to meet the stringent D4 exhaust emissions level and to achieve excellent fuel economy. The wheel-torque based engine and gearbox management systems optimize engine operation in terms of efficiency and emissions.
