Well... I couldn't decide which of my sketches to use for a contest entry, so in the end I decided to try something a little more radical.
I give you the next generation of the Nissan GT-R. I envisioned a kind of "racecar for the street" look, hence the numerous gaping vents and high rear wing. I took the "vanishing" A-pillar from my Datsun 510 concept and applied it here; the glass continues forward from the greenhouse, framing the hood before becoming the headlights. The massive grille was partly inspired by the GT-R concept, but substantially enlarged to give the front more presence.
