The new 1.0l 3-cylinder TFSI engine by Audi represents the next stage in the evolution of the EA211 series.

First used in the VW Polo, the engine developed by VW in Wolfsburg is the new entry-level option for the 2015 model Audi A1. It replaces the 1.2l engine of the EA111 series. The engine has more power and achieves better fuel economy than the outgoing unit while meeting the EU 6 emission standard.

The new engine is not only about 15 kg lighter than the 1.2l engine from the same series, but also produces less internal friction. The initial engine develops 70 kW (95 BHP). Further performance classes will be offered at a later date. Audi also plans to use this engine on its A3 models.

For the first time, Audi is offering a 3-cylinder petrol engine. Although 3-cylinder engines already existed back in the days of Auto Union, they were twin-stroke engines. The last production passenger car to feature these engines was the DKW F 102 produced in 1966. Its engine had a displacement of 1.2 l and developed 44 kW (60 BHP). Up until 1988, engines of this type were installed on the Wartburg 353 in the former GDR.

The technical description of the engine in this SSP refers to the Audi A1.
