M3 has the best performance in the BMW 3 series, and M3 GTS is the ultimate machine specially designed for racing tracks; while M4 GTS is the integration of many high-end techniques, which was especially designed for M3 30th anniversary. 

The two generations of GTS are like brothers who are the king of their own era. Our render artist lets the two cars drive forward together side by side, as two heroes appreciating each other.
