The new Ferrari FXX K Evo has a small fin too.

One of the Vipers damn near blew over at VIR with the smaller overhangs and less pitch sensitive underbody of the old rules. It's a serious problem that hasn't been getting seriously addressed.

I'm not an expert on such matters, but doesn't the extra 400kg of weight on a GT car mean it takes even more force to blow over compared to a LMP? Also, does the diffuser on the current generation of GTE cars increase or decrease the likely hood of a flip?

If those gets high enough it should increase the possibility of a blow over. At the very least it won't be helpful.

Cars were up to around 950kg when blowovers were common place and the lightest GTE cars are under 1200kg so it's really only a 250kg difference at minimum.

An LMP1 car is 4650mm x 1900mm while the Ford GTE is presumably 4963mm x 2050mm (both longer and wider than GT1 cars were allowed in the 90s) so it has ~15% more floor area. LMP1 has a maximum combined overhang of 1750mm while that gives the Ford 2253mm, which is a crapload more and once again actually more than the Mercedes CLR (2220mm)



Then of course they don't have the pitch sensitivity reducing stepped floor or required anhedral splitter of a post 2004 LMP either so their underbody package is actually very similar to an old GT1 car.

The current diffuser looks like it should create a more powerful aero imbalance if the car starts going nose up.

I guess, i was thinking more of a car getting sideways and flipping, as the P1's did, not the straight lift of a nose backflip situation. Either way, nobody wants to see cars get airborne and I think the rule makers are probably included in that list.

My original reply was supposed to say "the nose" not sure how it turned in to "those". As far as getting airborn in yaw condition like we were seeing I don't think it would help once enough air moving at a high enough speed begins to pass underneath the car. All of those aero devices have a very limited amount of yaw where they actually work. That's why high downforce cars snap so suddenly. Once the air begins to move over the car in anything other than straight over it, all of that downforce that it just had is now immediately gone and if a high enough pressure is built up underneath the car it's liftoff.

You say that but to be honest, those clips are the most often shown of Le Mans.

Good publicity for the race and no serious injuries, and let us also be honest with ourselves we all remember them

New front fenders and diffuser from what I can see. The diveplane area has changed and it looks like there were two different front splitters being tested.

Musical chairs at Porsche GTLM. S365 says Tandy and Bamber go to IMSA full time (which is a good move). Pilet in the other car has been mighty so good move keeping him in play. Bruni and Vanthoor to WEC fulltime (also a good move and my WEC super season pre-season favorites for the title and glory at LM )

Of the two pairings in WEC 2017, who gets the reduced role (or is there a 3rd car in the works)? The 92 car has looked much racier than the 91 car all season. Kevin Estre has been phenomenal and seems likely to stay. Christensen not too shabby although he binned the car at Le Mans. Unlucky engine failure in Shanghai where they dominated until that point. They have had a litany of DNFs on the season. 2 mechanical failures (Shanghai, Silverstone) and the accident at Le Mans which was a double points round.

In the 91 car, Lietz and Mako are somehow 3 points off lead for drivers title going into final round in Bahrain. I don't know how they have ended up in this position as they haven't stood out this season. The 92 car would have been the better placed car in each of the races where they DNFd. If they take the title, it will be hard pressed to push them aside.


My guess for WEC
91: Vanthoor, Bruni
92: Makowiecki, Estre

New Glikenhaus SCG 004 will be in 2019.
This Is Glickenhaus's Volume Road/Race Car, starting at $400,000.
The car should be available as a GT3 and a GTE/GTLM race car.

Impressed to see AF Corse and Ferrari sweep all of the championships in the absence of Gimmi Bruni.
