Yes, the BMW is not exactly pretty, though it does look a bit better in side view. Even their testdriver Christian Klien called it the ugliest F1 car he had ever seen! :d The BMW is just a temporary solution and not next years' car. Honda tested today with 2009 aerodynamics as well (Except the rear wing) and their car looked slightly better. Williams tested only the '09 rear wing while the rest of the car remained in 2008 spec. Ferrari showed up with a big hump on the right side pod which housed their version of the KERS (Kinetic energy recovery system).
McLaren, Renault, RBR and F1ndia tested several drivers in their '08 models. The 'World Series by Renault' champion, Dutchman Giedo van der Garde. got his chance to try the Renault today.
