You don't say! The car looks sooo generic, and also makes me realize just how much I dislike those gigantic front fenders.
Generic? What makes you say that?

All LMP1 cars have to fit specific regulations so you can't exactly race a Porsche 917 anymore, unfortunate as that is.

The regs do not force them to have those ugly bulbous 'pontoons' in front of the front wheels that start nearly vertical on all new LMP cars. I was hoping new narrower front tires would revert the trend back to sharp and slim front fenders, but everything looks like a fat version Lister LMP these days.

You would have a point but for the cars overall width is decreased! You lose 10cm of width overall and 1-1.5" (inches) of tire width. Thats 2-3" of tire gone compared to 10cm of car gone. 10cm is 3 and 15/16 inches. So 4 inches narrower car with tires only 3 inches narrower. How are you going to design your car? Even with narrow front tires with less contact patch, that would still be relatively the same car to wheel ratio as now. These new regs don't change much which was the criticism of them.

nice i like it so far, hope it makes it on track and sells some to replace lola.maybe rebellions announcement? as for them all looking the same, hasnt there been many points in time were the top wining cars looked like each other and others followed?theres not much freedom in regulations anymore for much self expression, if audi designs something that works then others will follow, look at toyota and their fender wing extension now audi and rebellion run them. also toyotas ran at the 750mm tails now audi does and its a magical long tail, i bet toyota is already working on an exhaust blown defuser.

Mike explains in great detail why the engine cover is much larger and higher than in current LMP1s.

I think the bulkiness will be hidden better with other cars. Seems like the rules are making for some not so pretty cars. I like the holes inside the rear fenders, looks better than on top.

Thanks for posting, it's a bit hard to follow his updates without a RSS feed in his website (I don't use social media )

Something is bugging me a little bit.

They talk about the importance of lower drag but they choose an open front splitter, isn't a closed one better for that purpose ?

Fair enough. But for some reason I thought it was the absolute width of a tyre that forced aerodynamicists to shape fenders in order to direct air primarily around the sides rather than over the top (like on older Lola cars). I guess there are other benefits to making more or less completely vertical fenders and try to direct all of the flow around them. As a result there's a very long and tall front overhand. TS030 is a good illustration of that, it is a bit of a bull-terrier in side-view compared to older protos.

Better for that purpose under the current regulations. Perrinn addresses that when he states, "It is not black and white, it will depend on how far each solution is developed. So in my opinion, it is important to commit to one direction quickly and develop it." Details become a bit more nuanced when we're looking at ACO2014 vs. what we currently understand. But also understand his quote also speaks to practicalities; at some point you need to move on and develop either one or the other concept.

Thank you for clarifying that, I didn't understand completely the first time I read it.

“The regs do not force them to have those ugly bulbous 'pontoons' in front of the front wheels that start nearly vertical on all new LMP cars.”

No, Physics forces that. Either you use what works best, or lose.

“They talk about the importance of lower drag but they choose an open front splitter, isn't a closed one better for that purpose ?”

I think that is so if the car porpoises the front end doesn’t seal to the pavement which would kill all airflow out the diffuser and make the rear end weightless.



What I think is interesting is that there are still people out there with the passion to produce P1 cars. Perrin has to be making significant investments just to get as far as he has.

As the economy heals (assuming it does, globally) companies like Perrinn, Multimatic/Lola, Oak will be invaluable. We cannot count on another Porsche 956/962 to come along, and even if it did, options and variety are wonderful things.

Thanks, captain obvious. If that's really the case, it may be worth adding that the laws of physics remained largely unchanged over the last 10 years

The laws of fysics might be unchanged over the last 10 years, but the understanding of them and implementing that understanding in building a racecar surely has changed fast and a lot the last 10 years!
