Don't know how Porsche Cayman/Boxster GTS 4-banger sales fared, but maybe the following could be an indication that things didn't work out as expected: 2020 Porsche 718 Boxster GTS 4.0 and 718 Cayman GTS 4.0 = back to 6-cyl NA (see
here for the official info). This may upset current GTS 4-banger owners though (value taking another hit).
Base price over here in Belgium (manual transmission):
- Porsche 718 Cayman GTS 4.0: 85,256.60 EUR
- Porsche 718 Boxster GTS 4.0: 87,313.60 EUR
- Porsche 718 Spyder: 96,170.80 EUR
- BMW M2 CS: 96,500.00 EUR
- Porsche 718 GT4: 99,074.80 EUR
Price-wise, these 718 GTS 4.0 models may be a closer competitor to the M2 CS than the 718 GT4. Of course, also consider what the cars get as standard equipment.
6-cyl reference in the license plate and the "6" stitched on the shirt: Porsche marketing folks getting pretty overzealous in a "Petrolheads, please can we be friends again ?" fashion...
