McLaren MCL33

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

anyone actually noticed how they take the floor to fulfill the slanted rule?

What are the chances of Mclaren following Renault's exhaust layout and angle ?

Should work well with Mclaren's current upward bodywork at the rear ? ! ?

...I would bet it would let an upcoming car suck up even more.

Not a lot I'd imagine, in terms of performance it's not worth much at all - maybe nothing if you're already turning your exhaust flow well enough to help link the diffuser flow with the wing - which is why most teams already have winglets and gurneys on the crash structure.

No - there can be only one exhaust (plus 2 wastegate exhausts). Exhausts have to exit within 100mm the car centre line, between 220mm and 235mm rear of the car centre line. The last 150mm must be a straight, circular cylinder. It may point 5° side to side, and 5° up, but no more.

Totally aware of that

Asked if a periscope bodywork can be done over the exhaust pie on top of the crash structure

The photo you posted isn't actually showing a central periscope (it is two symmetrical exhaust exits either side of he engine cover) but I don't think there's anything in the rules that would restrict one per sé.

The issue with it though is that a lot of the hot areas of the car are right at the back of the car (such as the gearbox) so an exit halfway down the engine cover wouldn't be of much use as it would limit the amount of cool air delivered to these extremities.

No - body work isn't allowed in that area - hence why monkey seats aren't allowed any more.

Floor is different but the bargeboards look almost identical. Would imagine this would be one of the major areas for the Australia update.

I'd say the openings and inlets were already there during testing, shape wise it's probably a bit different but I'd assume they function the same.
The back part where it goes up was also there, it's for the rear wing support.

However, the black paint is new and it's around where the burned lines were during both weeks of testing.
Could they have surfaced the bodywork with the same material that the teams used to apply during the blown diffusor era? All teams had the surroundings of the exhausts painted in black, similar to here.
Those could be easy fixes for McLaren while they come up with a better internal design and cooling package for Barcelona, maybe.
