Technical analysis of the Mercedes W08: the king wants to keep the throne


The champion team has presented a car that lives up to the title that must be defended or, at least, so it seems, your attention to detail and complexity of aerodynamics. The Mercedes W08 gives all the feeling of being a prodigy when dealing with the wind to your step, and although its décor is very similar to that of previous years, at short distances it offers interesting things at every step.

Coanda Effect

On this occasion, we are going to ignore the front wing because, although there are changes with regard to 2016, it is certain that in general all the cars are modifications irrelevant from the point of view of innovation and tend to be previous versions that are later tested in the test. El morro also features recent news, but worth noting the bulb (3) which has at the bottom that aims to improve the quality of the aerodynamic flow that circulates under the same taking advantage of its smooth curvature to create the Coanda effect.


This effect, which became very famous in Formula 1 thanks to the exhaust blowers, says that a current-in this case gas – tends to be attracted to a nearby surface to his career. It is the same effect that we get when we put the convex surface of a spoon along the stream of water from a faucet. In this way, the air that circulates below the bulb is ‘pasted’ at the same and circulates in a more controlled way and efficiently. Obviously, this effect is only possible if the surface has soft shapes, as was the case of the pontoons in the times of the exhaust blowers already appointed, that the said Coanda effect fostered the effect of the diffuser.

Suspensions redesigned

Arriving on the suspension front, we can see that they have been modified in a substantial way. The two arms of the triangle bottom have been separated and the superiors have been high. In this way, the subject (1) that connects to the wheel has passed to incorporate one piece pivoting instead of doing it directly.

Also noteworthy on this front for a small detail that gives an idea of what worked which is the car: the brackets of the television camera (2) allow a slight separation of the knoll to take advantage of them, even minimally, as an element aerodynamic.

Jewelry in the pontoons

But if there is an area in which there is to stop paying attention, is in the immediate vicinity of the cockpit, something that is starting to be the norm with the bargeboards (4) as a star. These elements have been in some way released by the regulation this year and, therefore, the teams are taking the opportunity to give free rein to the imagination.


In the case of Mercedes, we can see a top fin independent located above the bargeboard of several elements and with base timing. For its part, the set of side deflectors (6) becomes the art of the treatment of the aerodynamic flow around an art with nothing less than three vertical elements that are born very close to the base of the pontoon, embracing the third of them to this pontoon at the top.

To finish, the mirrors (7) -larger than in 2016 – see it as just before the birth of a aletín (5) of considerable size taking into account the area. At the top we see as the air intake of the engine and adjacent systems is divided into three and multiple sensors (8) measurement.

No shark’s fin… more or less

Already in the rear of the car, the first thing we see is that the car does not have shark fin (9), although with nuances. In the afternoon session of the shakedown performed by Mercedes and with Valtteri Bottas at the wheel, was mounted a T right in front of the bracket base of the mechanism DRS that aims to emulate the effect of the shark fin, but without the inherent shortcomings of the same on windy days. In any case, the team has confirmed that it will prove to the traditional fin of a shark in Barcelona.


“We have seen many photos of the other cars, but from now until the first race, we will have a continuous programme of development. As you have seen, the car of the presentation was not the small ‘T-Wing’ and then we tested it and, in Barcelona, we will test different configurations. We will also have the long version of the fin in the test along with the new tailfins for Melbourne. In essence, the car will change the entire surface of aerofoil from here to Melbourne”. Aldo Costa – Engineering Director


slim Waist

Ending with the floor of the car -and ignoring the rear spoiler by issues similar to those of the front-, highlighting the large open space (11) Mercedes has succeeded in the same as a result of a packaging more than the adjusted of the internal elements of the car are reminiscent of the best works of Adrian Newey. It also highlights the interpretation of the slots (10) previous to the tire, which have as their mission to control the turbulence provoked by the same to prevent interference from unwanted.


once again Mercedes has shown that it is much more than the engine and the constant evolution and innovation of previous seasons will continue to be the standard pattern in 2017. It is to see the appearance of the rest of cars that claim to be eligible for the title, but without doubt the single-seater German marked tendency, in some aspects.
