When both motorregler and aerodynamic rules in recent years has been relatively stable, there must creative solutions to stay on top.
Day two of Formula 1's vintertest suggests that the sovereign-Mercedes-team again has taken on something smart.
Onboard-pictures from Lewis Hamilton's cockpit will be in any case examined in depth in the other garages.
They show a sophisticated system, where the Mercedes drivers at the Barcelona-trains and two longitudinal side sometimes pulling in the steering wheel, which affects the wheel position.
In a Formula 1 racer is the wheels are not as straight as on a gadebil. You talk about ‘the camber’ (how much the wheels leaning against the car) or toe-in (how much the tires point towards each other).
the Pictures show that the forhjulenes toe-in change.
If you click on the little gif in the tweetet, we will see Hamilton pull in the steering wheel at the same time that the angle of the wheel toe-in changes:

so What does this mean?
First guess was that it could affect the top speed or air resistance (drag) to straighten them out.
More leaning towards that it has with dæktemperatur to do. A clever way to generate more temperature before a turn, because the tires lose much temperature on the long longitudinal side.
Is it then legal?
the Rules dictate that the suspension characteristics must not be modified out on the track, but here may be another solution, which does not go against the rule.

One would certainly believe that the team had inquired in advance at the international motorsportsforbund, the FIA, which is the judge of the technical issues.
At a briefing over dinner finds Mercedes' technical boss James Allison, that is the case.
- It is not new for the FIA. We have spoken with them about it a space of time, he says, according to German Auto-Motor-und-Sport without wanting to reveal what the system exactly does, and how they will use it.
Rivals keep with warranty an eye on the German world champions. Already on Thursday's tv-images so that, among other things, engineers at the Renault stand in the garage and have a closer look at Hamilton onboards.
Otherwise, process the first four hours of the second testdag just as peaceful as the first day.
the Reliability is still unheard of in the top. Biggest problems were with Renault, which, however, still reached reputable 41 laps.
Lewis Hamilton drove an impressive 106 laps, while Romain Grosjean and Haas were næstflittigst with 87.
Times are still dearly no matter, because the teams have different agendas and are running with different weight and motorindstillinger.
It is well illustrated by Charles Leclerc (Ferrari) was sjettehurtigst and Lewis Hamilton (Mercedes) syvendehurtigst right in front of Haas’ Romain Grosjean.
Racing Points and Renault gave it a little more gas on a single lap than his rivals, while the remaining eight teams are within four tenths of each other on their fastest laps.
