Nice comparisons. Apart from HRT and RBR everyone has "shorter" sidepods, last season they were more "sleek". Now they are bulging a bit more and then dive in to the cokebottle shape much sooner. McLaren and Lotus seems identical in their rear end design but livery might distort the angles. EDIT: except the rear wing, they swapped designs, McLaren had those flaps on the bottom, now they don't, Lotus did the opposite.
Toro Rosso, Lotus and possibly RBR has longer noses,most others has a shorter one. Really good tool for armchair analysis.
