Much was made about the BMW Z4’s end of production back in August 2016. At that time, many thought the Z4’s exit would pave the way for the sports car that’s jointly developed by BMW and Toyota to take its place. That car has long been rumored to take the name “Z5,” but now, a new report from Autoguide is putting those rumors to bed. Apparently, BMW is not going with the Z5 name as we previously thought. Instead, BMW Americas chief Ludwig Willisch told Autoguide the car will be called “Z…probably 4.” Wait, what?
