Found the dimensions of the 1er coupe and converted them to U.S. measurements:
Length: 171.6
Width: 76
Height, whlb., track, etc. were not detailed in the U.K. press release. Suffice to say the 1er coupe is actually a bit bigger than I assumed it would, I really thought it'd be a "tiny tim", pint size car, though still small it's a nice size. Thank you BMW! I was almost afraid this car would be too small for me.
