Charles Leclerc 2020 F1 Pre-Season Testing

For the first time ever, the entirety of the Formula One
pre-season is being live-streamed — via the official F1
TV service
— which has given the sport’s most enthusiastic viewership even
more opportunity to watch the cars go round in circles and deliberate on what
it all means.

Testing came to a close on Thursday after three days of
track time (down from four in previous years), and will resume next week for
another three days. After that, the next time we’ll see the teams at the track
will be in Melbourne, Australia, for the season-opening

Pre-season testing, most fans should know, is often a poor
indicator of season form. Known variables, such as tire compounds, and unknown
variables, such as fuel load and engine mapping, confound one’s ability to
determine a car’s true pace. Teams have even been known to come to Australia
with substantially different cars than what they showed in testing.

, pundits widely regarded Ferrari as the strongest team on the grid
after a great showing in testing, only for it to have a terrible start to the
season. This year, viewers will hopefully not make the mistake of confusing
pre-season lap times in Barcelona with actual race-winning potential.

Spring Is Finally Coming: How should you prepare your car?

So what should you
look for in testing? Typically, the following: How many laps are the teams
banging out? Is anyone having a recurring or unusual issue? Is there anything
unique about the cars’ designs? None of it will give you a definitive idea of
what to expect in 2020, especially over the course of the season, but you may
be able to conjure a vague picture of how 2020 will start.

Distance covered, however, is not as relevant in 2020 testing as it was when the hybrid engine era began. Back then, most teams struggled to get through a single day of testing without major reliability issues. More recently, that hasn’t been the case.

After three days of testing, all but one of the teams have completed at least 300 laps, covering 11,371 miles in total — up from 9,035 after three days of testing in 2019. Reliability is, predictably, looking good across the board, though Renault does seem to be lagging behind somewhat, and Ferrari had an unexpected issue at the end of the third day.

As far as designs go, there aren’t many surprises. With few regulation
in 2020, most of the cars have shown up with design evolutions
rather than revolutions. With limited room for front wing development, most of
the aero work seems to have been funneled to the bargeboard area, where the
cars have gotten increasingly complex since

Crashed In Testing? This is where to get car repairs if you’re not Romain Grosjean

The talk of the paddock, which you already know about if you watched any pre-season footage, is the dual-axis steering system that Lewis Hamilton and Valtteri Bottas were spied using thanks to their onboard cameras. There’s been a lot of buzz about it in the last two days, though it’s uncertain yet as to how potent the system will actually be.

By pushing or pulling on the steering wheel, Hamilton and Bottas were able to adjust the toe of the front tires while driving at speed. Toe refers to the angle of the wheels in relation to the center line of the vehicle (the longitudinal axis). F1 cars are typically set up to have negative toe, also known as toe-out, which is when the front of the wheel points away from the vehicle. This helps improve stability under braking and can be used to adjust the balance of the car in corners.

The downside of having any sort of toe angle is that,
especially when combined with aggressive camber, it contributes to rolling
resistance and thus increases tire wear while reducing top speed. The DAS
system would allow Hamilton and Bottas to benefit from the advantages of a toe
angle in the corners while mitigating the disadvantages in the straights.

It’s never been seen before in F1 and, supposedly, the
system is deemed legal by the FIA. That means that if teams determine it to be
worth a significant advantage, and not too difficult to implement in their
current designs, you can expect it to be copied in short order. In fact, I
would bet that at least one other team will show up with its own take on the
system by Melbourne.
