I'm sorry to disappoint you, but what you've seen in testing, and the version shipped to Bahrain are not the same. Testing one was movable, this one is fully static. They've made it movable for testing just to be able to compare data on the go.

You can see fairing on the second pic, and on the first an undercut to deal with laminar flow that wasn't present on testing version.

The interview itself and the news report had different tone to it.....which to my mind still made the report sounds like a lot of speculations were added....

Anyone seen a high res of this pic? There is a very interesting pipe-like thing to the left of the wheel...

The pic also shows how tight the cockpit is and how little room there is for the driver to do anything other than steer.
If you are more fortunate than others, build a larger table not a taller fence.

Yep, nothing of the kind on the right. At first I thought it was a bump cushion, but it clearly isn't.

Anyone seen these new vents on the Sauber? Look familiar to anyone?

Oh, c'mon! Such intakes are used for years and years. Browse galleries from any hot race in 2009, 2008, 2007... and you'll see them. Ferrari had them when MSC was driving for them, Renault had them. That is typical spot for those.

What makes the difference is undercut at Mclaren's. The undercut and streamlined intake at MP4/25 cleary says "we need this not to choke at any speed". All the rest, just like Sauber's are just for cooling of cockpit.

2007 - Same place, one on the nose, one on the top, just different design.

It was meant for both over-speculative posts. :wink:

"Cooling of bottle", how could they test that in Spain at temperature that was 20 degrees lower than in Bahrain?

Second one was aimed at your post, meant to sound like "don't make something out of nothing". No pun intended, just wanted to calm things down a bit, since inlets for cooling at that place are common thing (as pics I've linked show).

Nope, cooling went would have no undercut, fairing, and would have been smaller.

Autosport and James Allen both seem to have grabbed the "snorkel" explanation, and Martin Whitmarsh is being coy about questions being asked. Either the snorkel analysis has some truth to it or - equally likely - McLaren are playing along with the rumours in the hope it might lead the other teams astray on a wild goose chase.
