S or two races are the principles of Formula 1 upside down. The Mercedes is actually a car that gets its tires to work quickly. The Ferrari, on the other hand, caresses its soles. The last two races didn't fit into this picture. Mercedes took forever to get the tires in the work window. Ferrari brought them up to temperature immediately.

For this, Mercedes drove marathon distances with the second set of tires in both Monte Carlo and Montreal. Ferrari didn't dare to do that in either case. That puzzles the experts. Can this season really be summed up in a simple way: Ferrari needs the cold, Mercedes the heat? So the complete opposite of before. Then Baku would have to be a Mercedes show again. And Ferrari would have to hope for a bad summer.

Mercedes blames problems on the cold

In Monte Carlo, Lewis Hamilton's bad lap with fresh tires out of the pits almost cost him victory. In Montreal, the Mercedes came out of the starting blocks slowly. The engineers don't just suspect the clutch. Apparently the tire temperatures were too low and the rubber did not develop enough grip.

The problem continued for a whole lap. If Sebastian Vettel hadn't taken the emergency exit in the target curve, he would have returned from the first lap with a lead of 2.5 seconds.

The Mercedes engineers have only one explanation for this: “Monte Carlo and Montreal are not only special routes, the temperatures were also far below normal. In Monte Carlo the road was still damp, in Montreal it was 10 degrees cold. When it gets warmer in Baku, we will light the tires again immediately. Ferrari and Red Bull should then have their problems again. '

Experts explain what is important in complex tire management:' What matters is how much energy you put into the tires and how much you get out. Ferrari and Red Bull seem to put more energy into it than take it out. That penalizes them in hot conditions. It is important that you achieve a good balance for most of the races. '

From the Mercedes warehouse it says:' How many wet and cold races do we have in a year? A few. We have to go through this. Our car works on most other tracks and conditions. ”

What is Mercedes doing in theStarting line-up?

Apparently that's only half the story. The suspicion is growing among the competition that Mercedes’s needs are not only due to the cool conditions. But also with the tricks of keeping tire pressure as low as possible. And that's exactly what becomes an own goal in the warm-up phase when it's cold. Mercedes has nothing to fear in Baku. It should be over 30 degrees warm the whole weekend.

The tires are conditioned by preheating while stationary using the brakes and the cooling phase in the formation lap so that the tire pressure initially drops. And with it, of course, the tire temperature. Bad for the start and for the first lap of the tire.

Ferrari has again observed hectic activity on the starting grid in Montreal with regard to preheating the opponent. You yourself are still poking around in the fog. The process can be decisive for the World Cup. Those who constantly drive with less air pressure in the race let the tires last longer.
