The twin blades for the roll over hoops is a departure from the usual interpretation and should help clean up airflow to the rear wing.  The front splitter is shadowed by a somewhat larger vertical front to the splitter/bodywork transition.  The R8 had a similar, if smaller/less obtrusive, feature.

The accompanying press release contains an interesting description of the front brake ducting, describing it as fully enveloping the brake disc allowing for the directed cooling of the entire carbon disc.  Though in looking up close at the high resolution images, it seems to these eyes that the brake disc is still very visible.  Though we can't be sure if the car photographed in the studio images had said cowling in place. 

The R10's front tires are wider to account for the difference in weight distribution as compared to the R8.

14.1.9 – Temperature inside the cockpit (closed car) :
The ambient temperature around the driver must not be higher than 30°C (86°F) whatever the temperature on the outside when the car is in motion. After a stop, the temperature must go back down to this value in 5 minutes maximum.  An efficient air conditioning system comprising a compressor, a condenser, a pressure reducer and an evaporator is compulsory for the closed cars. It must be described on the homologation form and approved by the ACO.

Subsequently the ACO has increased the all-up weight for LMP1/2 by 25 kgs making them 925 and 775 respectively.  Presumably this is to take into account the weight increases caused by the fitment of an air conditioning (AC) system.  This weight increase is across the board for closed and open-top cars (even though it is a regulation, understandably, for closed top only) in order to maintain parity.  To further that, the ACO is allowing a engine restrictor diameter increase for closed top cars (taking into account power loss suffered from running said mandated AC system):

Normally aspirated and turbo charged gasoline engines:
For closed cars equipped with an air conditioning system, the following restrictors diameter must be increased by :
- 0.5 mm for 1 restrictor ; ;
- 0.3 mm for 2 restrictors ;

Turbo charged diesel powered engines:
For closed cars equipped with an air conditioning system, the following restrictors diameter must be increased by :
- 0.6 mm for 1 restrictor ; ;
- 0.4 mm for 2 restrictors ;

Note the .1 mm difference between the restrictor increase allotment gasoline to diesel?  Further case to run a diesel?  Figuring the AC's horsepower impact will be no different (or shouldn't be I would think) whether the engine is gas or diesel powered, I find that rule just slightly odd if ultimately inconsequential.  Though more power is more power...

The question arises why the mandating of air conditioning?  Well in previous years the drivers of closed top cars have suffered from excessive heat.  Though typically this effected the front-engined GT1s more so than the mid-engined LMGTPs.  Though you have to ask yourself why this has to be mandated by the sanctioning body?  There seems to be evidence enough to encourage the teams to implement such a device themselves if simply to keep their driver's fresh (and fast!).  Regardless, it is a new rule and one to be dealt with.

Finally the regulations are more specific regarding wear rates of the 20 mm underbody skid:

3.5.6 - Skid block :
a/ It must :
a.3 - have a minimum uniform thickness of 20 mm. A maximum wear of 5 mm will be permitted at the end of the practices and at the beginning of the race. The skid block will not be checked at the end of the race.

Previously the regulations stated nothing in regards to how much (if any) wear was allowable.  It is good to see that the ACO won't go the route of the FIA in regards to skid wear and removal of race results (recall the Spa-Schumacher debacle circa 1994) in that they won't be checking them post race.

And finally, much less significant though worth a mention:

5.5 - Exhaust system :
5.5.1 - Noise level : see sporting regulations.
Dynamic sound readings will be taken during the 2006 events.  The method of measurement and the results will be given to the competitors for information.  As from as 01/01/2007 the sound emitted from each car will must not exceed 113 dbA during the qualifying practices and the race.  The measurement will be made at 15 meters from the edge of the  track.

>>John Evans is offering up for sale his Evans Series 3.  This is the original prototype (and only example).

The Series 3 is noteworthy for one reason in that long time Kudzu designer Dave Lynn was responsible for the car's design.  Dave adds, "This was one of the first bodies that I designed that was actually produced so it is also close to my heart.  I think John and I did a pretty good job.  There is no telling how many chances you might have to own a car with a body designed by Dave Lynn!  There are only so many to go around and Jim Downing and Dennis Spencer seem determined to hog the Kudzus.  Beyond that both John and I might currently be considered starving artists: be a patron of the arts!"

The Evans Series 3 car is street legal, featuring a carbon composite frame as well as carbon bodywork.  It has a Supercharged 3.8L Buick engine.  Also included is a subframe for mounting a Corvette V8.  The interior of the car is nicely finished with carbon fibre adjustable seats, carbon panels, leather wraped roll cage and Stack digital/analog tachometer and data readout.  The steering wheel is fitted with a quick release hub and a halon fire extinguisher is fitted under the front of the passenger seat.  The car is fitted with 4 point harness for driver and passenger.
 
 
 
 

Evans Prototype built as FIA & EPA certification mule.  Supercharged 3.8 L V6, 5 speed w/LSD.  Pushrod suspension and ride height control for road use.  DOT glass, cats, great car for track days, carbon fibre body, frame and seats, full roll cage.  Will also sell molds, tooling and drawings to produce the 3 and 4 Series cars. 

All CAD drawings, specifications and documentation for frame, steering, suspension, drive train, along with build book of assembly notes and supplier list.

All this for the total package price of $95,000.
