It is interesting to see this season (2004) F1 cars beginning to evolve away from the standard that all cars pretty much have evolved into the past few seasons.
Racing is about speed and winning, aesthetics don't make you faster...good design and engineering do. I personally think the Williams is "interesting" looking, I can't claim to be an expert in aerodynamics but as a layman the new nose on it seems to offer advatages. Remember how people reacted in the early 90s when noses on cars started lifting.
Ferrari have recently said that the new F2004 will have a "interesting nose"...we shall see.
The renault is by far the most interesting car to come out this testing season. I doubt they will be where they were last season, not due to the aero of the car which looks amazing...but due to their new engines. Grand prix weekends could turn into a Renault vs. Honda rolling grenade game. But th e look and design of the car is amazing, they seem to be pushing and pushing, hell their car last year got them as far on mostly it's aero.
The Ferrarri F2004 remains the wildcard here. It is the only title contender not to have their new car out testing, while Williams and McLaren have. If anything I think 03 woke up the sleeping scuderia beast and knowing Ferrari they will come out fighting.
The bridgestone vs. michelin issue is the other big one. It comes down to essentially the Michelin's seem to be superior over short distances and hot laps (i.e. single lap qualifying) but over a full race distance the two tires are just about equal if anything bridgestone still has the edge (there compound seem to go off slower, but when they go off they are REALLY off). We all know about bridgestones in the wet.
Ferrari and the new "saberarri" being close to the same spec as far as tires are concerned is great. Bridgestone can focus on develping tires for ONE chassis and exploit it all. Jordan and Minardi will take and like whatever they get from ferrari, they don't even matter in the equation. Michelin has 6 teams and 6 chassis to develop for. Focus i think will win out over being all over the place.
04 should be an interesting year.
