McLaren's Heikki Kovalainen said on Monday he could remember nothing about his Spanish Grand Prix accident after being cleared to leave hospital in Barcelona.
"I have a slight headache and a stiff neck, but apart from that I am feeling well and in good spirits," the Finnish driver said in a statement after the heaviest crash of his Formula One career on Sunday.
"My focus is on getting better as soon as possible so I can pass the FIA medical inspection required to allow me to race in Turkey," added the 26-year-old.
"I don't remember anything from the accident or what happened afterwards," he said.
The Turkish grand prix, fifth round of the season, is in Istanbul on May 11 and Kovalainen will have to satisfy the International Automobile Federation (FIA) that he is fit to compete. McLaren said the Finn, who crashed while leading in Sunday's race after both Ferraris and team mate Lewis Hamilton had pitted, suffered a wheel rim failure. They said Kovalainen was travelling at around 240kph when the front left tyre deflated, sending the car into the tyre wall at around 130kph with the driver experiencing a deceleration equivalent to 27g, or 27 times his body weight.
McLaren chief executive Martin Whitmarsh said that was greater than the force experienced on ejecting from a military fighter jet.
The accident could have had far more serious consequences, with the car completely written off after penetrating into the tyre barrier.
"The front of the chassis broke off," said Whitmarsh. "The chassis is wedge-shaped and we imagine it went into the barriers until the point at which it snapped."
Triple champion Jackie Stewart told Britain's Sun newspaper that it was a miracle Kovalainen had survived.
"Heikki is a very lucky boy," he said. "If that had happened in my day, he wouldn't have had a hope in hell of walking away from it. "For Heikki to come out of that accident shows just how much we have come on in terms of safety."
McLaren said scans at the hospital had confirmed the driver suffered no head injuries or broken bones. He will stay in Spain for a few days relaxing before returning home and resuming light training.
"Heikki was briefly unconscious (in the crash) but he was lucid soon after the accident and I'm told he was actually quite jolly, which is fairly typical," said Whitmarsh.
Hamilton finished the race in third place, leaving the Briton second in the championship but nine points adrift of Ferrari's Kimi Raikkonen.
"The three quickest teams - ourselves, Ferrari and BMW-Sauber - looked to be very closely matched," Whitmarsh said in an assessment of the weekend. "Renault has taken a major step forwards, too. "We know we have some more developments coming through and we have to make sure we get them as soon as we can," he added.
"There will be some more new parts on the car in Turkey and we simply have to keep pushing."
