It's no-keel chassis. Brighten the monitor and you'll see it.
Completely new car. No struts
triple-blade front wing, almost double-bridged.
Exhaust outlets streamlined at the bottom, forming an inverted raindrop shape.
Sidepod inlets smaller and I think spoon and first blade's inner parts are to grab coolest possible air and direct it to sidepods thus improving the aero efficiency of front end of the chassis.
Clutch cooling outlet in same place as Ferrari's from F2007.
Ugly livery makes it look ugly but in fact it is quite interesting car. They should have figured out by now that you can't have sharp, straight livery lines on a curvy car
