The promised era of plain speaking and openness appears to be starting at the top, as promised: Volkswagen‘s CEO Herbert Diess has revealed details of two future engines and announced a facelifted Golf, way ahead of the public debuts.

According to Australian website motoring.com.au, which quotes the head of the VW brand, a turbocharged 1.5-litre four-cylinder petrol unit will replace the existing 1.4 TSI from early 2017. It should be revealed under the bonnet of the facelifted Golf on 29 September at the Paris motor show’s first press day. The new 1.5 TSI will feature cylinder deactivation, direct-injection and a new turbocharger: the unit is an evolution of the 1.4 TSI, not part of any new engine family.

The Volkswagen Group’s 1.6 TDI is also for the chop and will be replaced by a 1.5 TDI. After the new units appear in the biggest selling VW, they will become available in the next Polo and other models, before being fitted to various SEAT and Škoda models.
