One of the RS’s “jobs” is to reinvigorate interest in a mark as the average life of a focus Mark is around 7-8 years with a 3-4 year ish facelift.
As after 5 years the model has began to become stale and the RS launch in the last 3 years of the marks life is basically an interest raiser in the model again. With the Zetec owner now having a connection with the RS boosting sales.
Releasing the RS earlier could / would sell more RS, but would they loose out in later years in a loss of sales against say GM on bread and butter cars, who release their Astra in or around the 6th year of the Focuses life.
