Vodafone McLaren MP4-27 Mercedes

From what scarbs says, the original "fan tail" of the mp4-26 was very similar to rb6 solution also; it was only a bit more elaborate and a lot less reliable

Could McLaren's body work near the exhaust outlet be configured to allow different configurations during the tests?

Yes. That panel is small and quickly changed. No doubt they have designed it so that a few solutions can be tested. I'm actually quite surprised they didn't have significant variations at this test. I expect something new after the figures have been crunched back at MTC.

Right across what air flow? The air flow remains tight to the side pod - that's how laminar flow behaves (well, you'd hope they have laminar flow there, if they have turbulent flow they'll be generating a *lot* of drag). The exhaust bulge pops it up and over the fast flow that they're trying to keep for the beam wing.

This is being a bit picky, but don't confuse the terms "laminar/turbulent" with "attached/separated". The flow over a majority of an F1 car is most likely turbulent. Taking a standard Reynolds number of 500,000 for turbulence (simplified theory) about 88-200 mm back would be transition along any given uninterrupted surface depending on speed (80-200 mph).

Hi everyone,

First post, but I've been following this forum for a couple of years and I think it's brilliant.

This was posted by a Finnish journalist from twitter, it's meant to be a shot of the McLaren side-pods to be used to the first Barca test...



I can't speak for the reliability of the source, but it was posted on F1Enigma's twitter account and he tends to be pretty accurate.

Uhmmm ... *scratches head* .. I got nothin' ...

Well it's not a MP4-27, 26, 25, 24, 23 or 22 by looking at the livery and logo locations. But it could be a show car that's been made to look like a 26. Obviously it would have to be pre 24 by looking at the sidepods.


Slightly larger view here.

It's a mobile simulator tub that McLaren takes to events, for fans and sponsors to play with...



Unless you guys really think that F1 cars can be split in two for shipping.

I'll go back to just looking and not posting!

The sidepods look 27-ey to me...

Don;'t feel bad - I think my first several posts here were just outright ignored.

That showcar/simulator car is the mp4-20 of 2005, with a change of livery, as they weren't sponsored by vodafone then.

It really isn't – the side pods are way too square for that. To me it looks like an MP4-25 but hacked about a bit.

I'm late to the party, but i'll give my 2 cents.

I think ultimately we are going to see the exhaust point at the bottom of the rear wing. at slower speeds the exhaust gasses stand a chance of actually lowering the pressure underneath the wing because of the heat they introduce into the airflow. Thus making it more efficient, and allowing the use of a smaller wing. This concept is also beneficial at high speeds, because you are using a smaller wing, and thus producing less drag. Think of it as a blown DRS.
