Technical analysis of the McLaren MCL32: a hint very thought-provoking


After witnessing the presentations of cars so bold in some issues such as the Renault RS17, Mercedes W08 and the Ferrari SF70-H, many observers have been somewhat disappointed with what seen on the new McLaren MCL32.

But this McLaren has many more things than at first may seem, not only for what it teaches (spoilers front and especially rear suspensions), but by what you should have… and there is. If McLaren is characterized by something that is not precisely by conceiving of cars simple and away from the daring and that today has been presented in Woking hints at many more things than the eye can see.

front Wing is very complex

although it is not habitual that we stop at the front wing, on that occasion we are going to do because of the MCL32 is the perfect example of the complexity that may involve a car to current Formula 1. In general, the greater the number of flaps, ability to generate more downforce there will be, but also a higher risk that the load behaves unstable. In other words: we will get more, but it will be more difficult to dispose of it in a continuous way.


In the case of McLaren, we can observe how the plane main wing (3) is divided into two, while the flaps side (1) add up to four and one of them is double in its part closest to the Y250 (the central part next to the morro in which you can not work aerodynamically by regulation. Following the complication, the box adjacent to (4) the endplate is also divided into different parts and flaps. All of this has as its mission to two main tasks: to generate downforce and to create vortices that restrict the turbulence coming from the front tire, as well as trying to avoid in the extent possible that the aerodynamic flow main shock with that huge black mass, and with the ‘annoying’ suspension arms.

Suspensions redesigned

Going to the nose of the car, we see that the tip is the same as last year, but the wing support (6) it has been sophisticated so very remarkable, extending the channel to a mode similar to that of the Renault RS17, but adding three gills, with which you surely are to speed up and feed the stream that flows toward the keel and the splitter.


also Noteworthy the input and output of the S-Duct (8), especially in discrete and close to the support of the first. Further back, in the vicinity of the wheel, we can observe how different are the air intakes of the brakes (5) with respect to the Ferrari SF70-H and also check out the redesign of the suspension with the arm, front upper – (7) lower than in 2016.

Pontoons very small

The standard pattern of the season, in addition to working a lot of the area near the cockpit, is the present pontoons (9) reduced to the minimum expression, a circumstance highly influenced by the stability of the regulatory in thrust units is concerned. In this way, the efficiency and cooling needs, every time is less and that allows you to compress even more all the internal elements of the car.


In relation to the bargeboard (10), although it has to be anchored to the chassis quite elaborate, as well as its binding to the floor of the car, what is certain is that it is not as complex as some of those seen in other cars. In regards to the deflector side (11), its resemblance with the Renault RS17 does not go unnoticed, but instead of starting on the floor of the car, makes it into the top of the bargeboard and, after going back until you reach the line of the pontoon, it ends without continuing to over the same with a horizontal plane. In contrast, the pontoon is held by two appendices that serve a similar function.

Missing things

But if something strange in this area -and serves as an appetizer of something similar in the rear – is what is not seen. No appendix any in the immediate vicinity of the cockpit -or on top of the bargeboard, or next to the rear-view mirror-, nor on the floor of the car (12) are profiles, or bumps (or an internal channel as in the case of Renault, Mercedes or Ferrari). In fact the entire floor of the car remains completely clean and not even in the vicinity of the rear tire (15) there is any trace of a work which, with all security, it has been done. This, along with the diffuser capping (20) to not reveal the secrets of such an important element to the overall performance of the car, evidence that there are many details of this McLaren that we do not yet know.


rear Spoiler, innovative

the rear area of The car, a floor apart, is another story. The shark fin (14) arrives at McLaren and with a considerable size, but it does not serve of base for the support of the actuator of the DRS (16), born next to the exhaust of the thruster.


But what really draws attention is the rear spoiler, which has some of the details are truly eye-catching. The first of them is the use that McLaren makes the curvature caused by the regulation to place a series of three gills (17) in the endplate so that they are suspended in the vacuum, and open up a hole substantially in said endplate. These elements do not seek to generate load, but allow the spoiler to work in a more clean and uniform, enhancing, therefore, their ability.

below, in the lower end of said endplate (18), we find four gill-more, in this case most common. But which is not or much less normal is the mode that has been chosen by McLaren to set the rear spoiler to the car. It does so by three points (19), but not in the conventional way. The center serves to turn actuator of the DRS is born of the structure of an impact and that hugs the exhaust, while the other two go down to the diffuser (20) through a tiny sheet of carbon fiber from both endplates. Finally, we find more gills at the top of the endplate (13), although in this case more conventional and without cutting up the front edge as the team McLaren already made in 2016.


In theory the main problem that can arise is the rigidity of the whole that could cause the rear wing to lose aerodynamic stability, , but as counterpart you might even get to flex at high speed -getting McLaren with this limit the drag and increase the top speed in a straight line-.

mixed Feelings for both with this McLaren MCL32, alternating points diffuse with other great, if they work in practice as in theory, can make a difference. As they say, will have to wait for the test to begin to see the condition of each car and how the innovations implemented. Something that, in the case of McLaren, it is even more real, since several important elements will be announced at that time and not before.
