Porsche's New IMSA GTLM Car

[RonDent]

Porsche has made some changes to their car for the 2017 season.

Porsche Unveils The Most Spectacular 911 Ever at the Los Angeles Auto Show | IMSA

I wonder just how much that costs?

I don't think I will order one.

Many years ago I saw a brand new 934 race car. I remember new it was the price of a nice new house. Now I bet it is real pricey.

[John Rogers]

Hummmmm rigid mounted seat and movable pedals. I had that setup in my 914-6 vintage race car back in 2000!

[RonDent]

No mention of the price. But you know what they say.....if you have to ask, don't tell your wife what you really spent for it!

[tevake]

Cool, I wonder if that means we are headed for a mid rear engined 911 in the near future.
What are the homaligation rules, still require some similar production models?

Almost seems a Cayman based car would have been a shorter route to get there.

I'm sure at least $500K.

I wonder why they didn't go turbo since the rules seem to favor that as shown by Ferrari and Ford.

I'd like to see the rear seat area to see how much the engine takes up.

I've been waiting since 2015 for this car to be made public, having produced then (at the previous job) some parts which have no place in a "traditional layout" 911. It's very interesting that they didn't need a waiver to change the engine position. The 2016 LMGTE technical regulations contain the following, but there may well be an update for 2017, which will not be made public until later in the year:



So, location as original but position and orientation is free, but in true FIA fashion it is not very clear cut in my opinion. I reckon there is plenty of scope to move the engine forward (free position) and still be rear-engined per the regulations, even as they are written for 2016. This article seems to hint at this as well: Porsche 911 RSR (2017): Neues Motor-Konzept für Renn-Elfer - AUTO MOTOR UND SPORT

Finally, the diffuser free volume only starts at the rear axle line, so in fact completely flipping the drivetrain around to create a true mid-engine layout may not be necessary, or beneficial (as the leading edge must be on the reference plane/flat bottom):



I'm sure we will learn more about this, or the "double wishbone" front, in the near future. Plenty to look forward to for the 2017 racing season already

PS how nice of them to carry on the Audi Sport colours

A bunch of us have been saying that they need to put more power in the Cayman....

[rusnak]

Yeah, I read that and thought "Cayman with a bigger motor and ground effects"

1.2M€ was quoted.

Must be tough sitting on a secret like that Won.
Thanks for the details about the wriggle room in the interpretation of the rules.
That's quite some latitude that P- folks are counting on.

Well they clearly did not design the diffuser/ extractor for looks. It's gona be interesting to watch this new car in action.

I doubt the other constructors have been idle over the off season, but this looks to be quite a leap forward.

Mid rear?
I missed that. I assumed that they just flipped the drivetrain??

[OffCamber00]

Yes. Drivetrain was flipped - engine is in FRONT of the rear axle. This was done to take advantage of the 2016 changes to the ACO GTLM regs freeing up aero restrictions at the rear of the car. Porsche was woefully outclassed this year by the new 488 and Ford GT which were built to take advantage of those regs.

The mid engine has been trailed for a while. However, what I find most interesting about this new car is that its normally aspirated. Everyone thought for sure it would be a twin turbo.

EXCITING stuff!!! Hope to see this at Sebring and VIR. Daytona is up in the air for me, right now.

Me too but unless the factory signs a new team to run the program, we will likely not. Core is moving from GTLM to GTD for 2017 so they will bring the new GT3 cup, not this beast.

That's true. But there is still a chance to catch them at CoTA in September. Hey, that reminds me, someone still owes me some pictures.

Yeah, I have been wondering the same.

[TRE Cup]

And The Racers Group will be running a Porsche program for 2017 in Imsa. They will still be running the separate Aston Martin and Lamborghini Super Trofeo programs too !

Yes. So happy to see TRG back w/ Porsche in IMSA. It will be another cracking season of GTD next year - but I will be missing Magnus. I doubt we will see them in IMSA after all of the BS this year.
