I like how Jay Leno describes this car as "chassis car" rather than "engine car". That V6TT engine is utilitarian - it is there just to do the job of delivering 650 hp and do no more and no less. It is just a power generating appliance with compact dimensions for perfect weight distribution. It is not mechanical art like a V12.
Does that make it a shit supercar? I don't think so, it makes it "practical supercar" - like Jay said - it was designed to win Le Mans, rather than and impress with pornographic, shiny exhaust manifolds or the most amazing sound.
Either way, the "form follows function" exterior still came out very striking and visually pleasing.
