Turbo fuel stratified injection Turbocharged fuel stratified injection (TFSI) denotes a type of forced-aspiration ("turbo") engine where the fuel is pressure-injected straight into the combustion chamber in such a way as to create a stratified charge. FSI (VAG) direct injection technology increases the torque and power of spark-ignition engines, makes them as much as 15 percent more economical and reduces exhaust emissions.[1]
Audi A3 After four years the third-generation Audi A3 was facelifted for the model year 2017, which also coincided with the 20th anniversary of the A3 name. The facelifted model was first unveiled through a set of official images in April 2016. The new A3 sedan was given significant cosmetic updates, which were in-line with the automaker's new design philosophy. As a result, the 2017 Audi A3 sedan featured the Matrix LED headlamps that were earlier seen in the A8 flagship sedan and the R8 supercar. The front grille was also given a refreshed treatment that made the new A3 look like its elder siblings. Changes on the sides and rear were minimal, with only the taillights getting new LED treatment. There were multiple updates on the interiors as well, with a fully digital 12.3-inch instrument cluster screen placed behind the steering wheel. Currently on sale in Europe and expected to be released in USA and Asia/Pacific 4 QTR 2016[54]
