This is what a 2008 F1 car with 2009-2013 aero would look like.

The story behind this car is that Honda was testing to prepare for the rule revolution of 2009 by putting a new front end on the RA108. The rearwing was unchanged, and as far as I can tell so was the sidepod.

Just optically I think these prototypes look fabulous. The 2008 proportions were spot on, and the wider front wing paired with the wide rear wings makes them look more aggressive. Maybe the rule makers should take a look at these machines.

There were other teams with test cars of this kind too, in this case Williams (beautiful low nose!) and McLaren.
