Most car runs minimum at Le Mans trim, and start adding more as lift-drag(negative lift) requirement changes. If they need more they will add more. Seeing the car is just being shaken down for Le Mans use, its not a off the mark guess that this is their lowest DF trim.
Cars are
not required to have louvres. They are need in some chassis for front wheel well air extraction to
balance front/rear downforce. I mentioned louvres as an example, since they penalise drag at low downforce circuits and are a good indication, if used in low DF trim, that efficiency is compromised because of lack of front DF. Also, the configuration and location of louvres is important, naturally.
Audi R15+ manages to extract enough air laterally behind the wheel to avoid their use, the fact that Norma apparently does the same could be a good indication.
I'm not saying that the Norma M200 is competitive. Nobody knows (and even after Le Mans, its full potential will still be unknown - Pegasus is a small team with little track record and the Norma will be the only petrol engined LMP that didn't benefit of any waiver, allowing him to not comply with 2010/2011 rules).
What I'm saying is that there are lots of things to think about when analysing this cars:
- ultimate performance isn't that paramount in endurance racing. For a privateer team, some with pro-am driver line-ups, it's more important for the car to be easy and confortable to drive by all drivers and easily exploitable technically.
- Norma sportscars are usually conservative, but competitive machinery. They seem to know what they are doing and what's important in endurance - they even have a backup system to allow gearshifts if any problem occurs with the paddle system. I think that's a nice touch and the proof that they understand what's important.
- The Norma is fitted with state-of-the-art costumer engine and transmission (a X-Trac unit). That at
(reportedly) half the price of any other LMP chassis. Since we are talking about a costumer chassis, from a company that plans on selling more, that could make the car marketable.
Concerning the use of armchair CFD (nice concept, is it open-source?
), I'm just glad that the level of discussion in sportscar threads isn't the same as in F1 ones...
