The theory of evolution

Keeping a keen eye on the MCL34's aero

The devil is in the detail.

A Formula 1 car is the perfect embodiment of such an idiom. A myriad of components, from mechanical to aerodynamic, each working in harmony to give a driver confidence that the car will perform exactly as they want it to. At least, that’s the idea… 

Aerodynamics are pivotal to performance and the development race naturally sees a Formula 1 car evolve over the course of a campaign. In the space of just half a season, the MCL34 has benefitted from a raft of upgrades – some more obvious than others.

So while our designers and aerodynamicists enjoy a well-deserved break during the summer shutdown, join us as we take a closer look at how the MCL34 has evolved.

Getting philosophical

The 2019 regulations have seen the emergence of two front wing design philosophies. Some teams have continued down the more conventional path of loading up the outer part of the wing to generate downforce. Meanwhile others, including us, have pursued the inboard-loaded route. We introduced a wing that’s steeper near its inner tips, and aggressively sweeps down to become flatter towards the endplate to direct outwash around the front tyre.

Summer cut

Sticking with the front wing, the endplates received a fresh, new trim just in time for the Spanish Grand Prix, featuring a small cut out designed to direct airflow around the outside of the front tyre.

Stay with me

The eagle-eyed among you will have noticed that the wing mirror stays on the MCL34 have gone from arrow-straight to far more curvaceous, to reduce drag and guide the flow of air to the wing on top of the sidepod.

Boomerang

Bargeboards have been an intensive area of development up and down grid, and that’s no different for us. The ‘boomerang’ has been tweaked, along with the elements that surround it which have grown in number and altered in size and shape. This multitude of winglets and turning vanes create vortices which combine to generate a powerful stream of air that is guided over the surface of the bodywork and directed to the diffuser.

Floor it

Even the floor of the car has undergone changes. All the little cuts and flicks around its edges create a high-pressure curtain of air which helps to maintain the low-pressure area underneath the car and stop air being driven to the diffuser from escaping.

Baby shark

Doo doo doo doo doo doo… Ahhhhh! We’d only just got the most annoying song of all time out of our head! The ‘baby shark fin’ on the engine cover got plenty of attention when we launched the MCL34, but this shark has grown up over the season. The fin has morphed into something much larger to direct, and improve the quality of, airflow to the bottom of the rear wing.

Hang on

The mid-wing, also known as the T-wing, appeared on the car in Hungary, and like the shark fin improves the quality and flow of air to the rear wing. Last season, the MCL33 sprouted a similar device, both of which look very similar to one of the hangers you might find in the clothes store underneath the MTC.

And finally...

Where there’s downforce, there’s usually drag and it’s up to our aerodynamicists to balance the trade-off between the two. When it comes to the rear wing, several different configurations have made an appearance during the season. And all have been driven by the need to optimise the car for a particular circuit type, whether it’s the high-speed straights of Canada or twisty streets of Monte Carlo.
