that wing is just standard far in the Japanese Grand Touring Championship... very Toyota in its contour.
anyhoo, this is just a cartoony drawing: it'd look much sharper in the flesh.
...and i'll remind you that RE Amemiya has designed some shockingly ugly rotary cars... but also some frighteningly origional cars, for which i gotta respect them.
btw, i love their last-year aero package for the 3 rotor in the GT300 series (yellow and blue)
for me, this concept is over-the-top Lotus... i just can't like it: not origional enough... but certainly not ugly. it's attractive, just not very creative.
...if they stuck to their 80's retro hard corner and contoured look, i'm sure i'd love it, just for the shock and origionality factor
