I have to disagree with you about the 2019 R percentage numbers not being significant as the percentage of R's built for the 2019 MY was significant and confirmed an increased trend/interest for the R model over a regular GT350 for the 4 prior years.Not sure how significant that is. The total number of R's was in line with most years. The production woes for 19 made for significantly less total 350's built
2015 Total 137
2016 Total 6694
2017 Total 7115
2018 Total 4378
2019 Total 3595
2020 Total ?
The higher percentage of Rs in 2019 are a function of a lower overall reduction in the number of 350's. Since Rs tend to be built in the early spring months I am not surprised
Looking back at the 2016 MY only 8.5% of total production ended up being an R model and each subsequent year the R model percentage continued to escalate up to the 2019 MY whereby the percentage increased to 22.4% which is a significant increase when compared to the 2016 MY.
When the final 2020 MY numbers come out I am confident that percentage of R's will again increase beyond the 2019 MY numbers and expect the 2020 MY R model numbers to be ~25% of total production.
When comparing the % of R model production starting in 2016 which was only 8.5% and ending in 2020 which should come in around ~25% the numbers speak for themselves and clearly indicate a growing trend of interest for the R model over the 5 regular production years.
