More of a Mclaren nose, and no sign of exhuasts? Weird considering the exhuast blown diffusers are supposedly not possible with the ban on Double Decker Defusers.

Much more purposeful than last years boxy car, conspicuously only a single tiny lotus logo on the nose...

No KERS on the lotus though....
That is it so far many more in the next couple of days as the 1st test kicks off and a few late comers like Mclaren in a couple of weeks.
