This car has broken the lap record at Valencia, so McLaren must have fixed the issues with mp4-18.
Never take any notice of testing times, If the car ran low fuel fresh tyres at either end of the day the lap times will always impress, It does however the prove the car is not a complete dog.
Looking at this car, it seems that McLaren is pursuing design efficiency using a different route to anyone else. Just wondering how Ferrari and Williams will react to this.
While the new Mac looks different to the rest of the grid, in fact McLaren have merely adopted a number of other practices from around the grid, compressed into one car. The result if it gels should be good, but the original 17 and 18 never gelled as predicted.
is The mp4-19 bargeboard fixed to the twin keel mounting? From my view, it is fixed to the keel and thus becomes a fixed aero device and can’t be changed anymore.
The keel only runs down to the suspension mounting, the bodywork ahead, behind and below it is removable and hence changeable through the season.
Does anyone has any technical pic of how the undernose shape like is it drooped-nose like F2001?
The underside of the nose on both the 18 and 19 is unlike any recent f1 car, it is more akin to the early nineties nose\wing shapes. The main plane and first flap element
are full width and hang from the drop plates under the nose section, but the second flap is split under the nose. This set up places the underside of the nose in much closer proximity to the wing than the F2001 for example. Splitting the second flap makes for a shorter chord, which will make less downforce and drag and upset flow less under the floor and into the sidepods.
Also, I think the suspension mounting are protruding to the outer side of the nose if you view it from the front and hence get in the way of the airflow. So the wave shaped front wing must have some shape to manage the airflow to reduce the intensity of the air that hit the keel. Does anyone have any opinion on this?
The twin keel set up for McLaren has always splayed the keels away from the chassis at angle, this creates less blockage under the nose and puts the mounting points where the bargeboards are placed. Hence making double use of the space. The wavy front wing (“W” shape) makes the most downforce in the middle of the outer sections this reduces the vortices near the endplates and improves flow under the middle of the car. Hence the keels are not placed in the main flow but instead direct this flow around the car.
Have anyone of you seen, what kind of a refuelling hole there is in MP4-19? I have seen a few pictures of the side pods, but there isn't any noticeable marks of that whole. I have also noticed that there isn't very much space for that. So, if someone can find a picture, where that hole can be seen, please send a link or the pic to this forum.
The refuelling flaps are horizontal between the driver and engine.
