The BMW M4 GT4 successor completed its first tests last week in Almeria, Spain. Development of the car is already at an advanced stage. The goal is to continue the impressive success story of its predecessor. To enable this, the new BMW M4 GT4 will not only feature the strengths of the current car, there will also be improvements in some areas. The BMW M4 production model provides an outstanding basis, while the new race car will also adopt certain components from its big brother, the BMW M4 GT3.
