I was wondering if the decline in C-max sales in the US was because of the hybrid drive-train. Or perhaps early EPA efficiency woes.
But it seems C-max sales in the UK have seen a similar decline, and over a longer range of years - - down every years, and off nearly 50% from the 2011 sales high:
So UK C-max sales have slid every year since before the US version was introduced. As far as I know, there is no hybrid version of the Euro C-max, so it is not a drop in demand for hybrids that has caused UK C-max sales to slump. And Ford as a brand is doing well in the UK, with sales rising as the overall vehicle market there has declined. And as far as I know C-max and other car sales are not being lost to pickups or SUVs in the UK, whereas this has been a factor in the US.
So it seems there is something about the car configuration or style or perceived value or competition that has caused a sales drop over the last 6 to 7 years.
