After months of staring at fieldtest trucks Renault gave away some design details on the new racetrucks. That was only a wild guess, but this drawing seems to confirm my thoughts. Check the shape of the grill on the drawing, and compare it with the racetrucks! Another detail that came to me through Facebook is the indicator. That looks impressive!
It is good to see that Renault is going its own way with the design. Where all the brands use the V-shape front design Renault does it the other way around. That does make sense, cause this way the widest part of the grille is on the lower end, just where you need the maximum cooling capacity!
