S It's nice that modern technology still leaves puzzles open . It would be boring if everything could be explained. McLaren and the FIA ​​examined Fernando Alonso's accident in detail on February 22nd during test drives in Barcelona, ​​they evaluated photos, videos and data, examined the car and helmet, and interviewed the doctors involved. And you are still unable to say: That's it.

However, you can rule out some accident theories. For example that of Fernando Alonso himself. The Spaniard said at the press conference in Malaysia: 'We definitely had a steering problem in the middle of Turn 3. The steering blocked when turning right. When I saw the wall approaching, I went from fifth to Shifted into third gear and braked. ”This is in stark contrast to the statement by McLaren, who had claimed that nothing was broken on the car.

Only Alonso can explain the accident

In the past few weeks auto motor und sport has interviewed many witnesses who saw the accident themselves, the video, the accident sketches or the data. This gives a relatively clear picture of the course of the accident. What remains open is the question of why. And that The answer can only be provided by the driver himself. The version that Alonso gave in Malaysia cannot be correct.

Let's start with the Spaniard's assertion that the steering was stuck A look at the accident data have confirmed us. That's impossible. The data clearly shows that everything was fine with the steering. Alonso never tried to turn left. Then the torque sensors would have hit the steering wheel. Even with the steering locked, you would be able to see whether the driver had used any effort to change the steering angle.

In fact, Alonso turned a little further to the right at the end of the curve. When the right-hand bend was followed by the straight in the direction of Turn 4, the car logically turned inward. Even Alonso's first attempt at an explanation is not corroborated by the data. McLaren had quoted its driver in a press release that the steering felt heavy. However, there were no pressure peaks in the hydraulic system of the power steering.

Did weakness lead to a misinterpretation?

Alonso is either intentionally in theHad driven the wall, or for medical reasons he was no longer able to steer away from her. Since we do not want to accuse the McLaren driver of intent, we assume a fit of weakness. It doesn't even have to have been a real blackout, as one of the accident experts explained to us: 'When he goes black in front of his eyes, his strength disappears. Under the impression it really felt to him as if the steering had become harder and harder. '

There were many different theories in the accident representation. Most of them were wrong. A Spanish sports magazine concluded, based on tire marks on the inner wall, that Alonso had got into trouble at the apex and then turned inside. It was the wrong tire tracks. The crucial thing only happened at the corner exit.

McLaren proposed that the crosswind could have blown him onto the artificial turf and that he lost the car there. That was denied by Alonso. 'At the speed I was able to achieve, not even a hurricane would have thrown the car off track.' The report that Alonso allegedly turned into the curve faster than before was also misleading. We now hear from a reliable source that he was driving less than 20 km /h on this 21st lap.

Alonso's assumption that a modification to the steering might be the explanation also doesn't seem credible. McLaren only modified the steering ratio at his own request. The additional gear was not damaged. Alonso is now driving the standard version again, which Button also uses.

No emergency braking in front of the wall

auto engine and sport traced the path that Alonso took on the lap of the accident through turn 3 based on witness statements (see graphic). Up to the apex, the lane resembles the ideal line. Then the McLaren drifts a little further to the outside, but without significantly touching the artificial turf on the outside. Which was confirmed by a photographer.

In this phase Alonso shifts down three times instead of two times as he claims and steers even more to the right at the exit of the curve. He just keeps driving the curve like it will never stop. From now on the nose points towards the wall. The McLaren is heading towards the obstacle at a speed of 135 km /h.

At this speed it could easily have changed direction or applied the brakes, but nothing happened. According to the data recorded, the braking maneuver is only a half-hearted attempt. Eyewitnesses, including the following Sebastian Vettel, said that the accident did not look like an accident. More like a failed parking maneuver.

Alonso doesn't have to have lost consciousness. Maybe he was just uncomfortable. He himself saysthat he could remember everything. Until the point in time when he switched off the radio and threw the main switch. Why he withholds the impact speed and the deceleration values ​​is again strange. They do not speak against his thesis, so he could have given them away.

Alonso accidentally sedated twice?

The McLaren hits the wall at 105 km /h. With the two contacts, the car is decelerated with 31 and 16 g. The ear sensors measure 18 and 8 g. Because the impact occurs from the side and the suspension remains intact, the force is transmitted unfiltered to the head. Hence the concussion.

It becomes puzzling again during the recovery. Alonso can clearly remember the accident. He is missing four hours after that. When asked about the unconsciousness, Alonso replied: 'It must have happened in the ambulance or in the emergency department on the route in front of the helicopter transport. The doctors told me that this was normal because of the medication I was given . '

There are now rumors that Alonso was accidentally sedated twice. At the accident site and in the route hospital. The high dose would explain why the memory of the crash came back with a delay and why there is a large black hole between 2 p.m. and 6 p.m. It would also be evidence of why the patient spent three and a half days in the hospital. Apparently they wanted to make sure that Alonso really just had a concussion.
