It will take longer if it is replaced. The current Mustang is a six-generation model, starting from 20 13. The history of wild horses can be traced back to 1964, 54 years ago.
The life span of the first generation of wild horses is ten years, from 1964- 1973.
The second generation of wild horses has the shortest life span, only five years, from 1974- 1978.
The life span of three generations of wild horses is as long as fifteen years, ranging from 1979- 1993.
The life span of the fourth generation wild horses is twelve years, from 1993-2004.
The fifth generation of wild horses began in 2005, followed by the sixth generation of 13.
In fact, the update is more to cater to the market, and there is no special regulation. For example, the second generation mustang, which is a transitional product to deal with the oil crisis, has a short life. The oil crisis also shortened the life of the first generation of wild horses to some extent. The life span of the third generation Mustang 15 years is due to its good market performance, while the research and development of the fourth generation Mustang is frustrated. The life span of four generations of wild horses is relatively normal. Although the five generations of wild horses performed well, their life expectancy was also discounted due to the financial crisis.
