BMW has released a series of official test videos showing the new M3/M4 prototypes being put through their paces around the NÃ¼rburgring. Also along for the ride was reigning DTM champion Bruno Spengler. Amazingly for a BMW driver Spengler says he’d never been to the Ring before. He is Canadian so we’ll be kind and cut Spengler some slack.
The audio track was published by Road & Track and is said to be an M4 being revved while at standstill. It sounds alright too.
