UPDATE: MY21 cars will be built from BW33 onwards.
Just received news about the upcoming model year change. I have no proper confirmation, however down the grapevine, people who work for Skoda in some markets have divulged some information:
• 190PS/140kW TDI new replaced with 200PS/147kW TDI engine
• New 180kW TSI engine available (Update: Will be replacing the 176kW 2.0 BiTDI - end of production BW48)
• New steering wheel from Octavia with capacitive hand detection
• MIB 3 infotainment, which entails the following:
USB C replaces USB A
No more DVD/CD slot, SD slots
Online functionality via eSIM (built in)
• KESSY sensors for all 4 doors
• Ventilation and seat depth adjustment available for RS/Sportline
• Sleep Package temporarily removed (due to supply constraints)
• ACC now only 210kph instead of 160/210
• Update: Predictive Cruise Control + multi-lane Emergency Assist available
• Update: Media Control not available
• Update: Beige interior for textile and Suedia upholstery not available
• Update: Optional USB Type C socket in rear view mirror cover now available
Here are some leaked images from Skoda of the new interior - main change is steering wheel. Last one is the Sportline, but that's the steering wheel expected to be used in the Sportline and RS. Skoda CZ should be releasing MY21 specification and price list next week.
