Former Toro Rosso driver Jaime Alguersuari has announced his retirement from racing aged just 25.
Alguersuari became F1's youngest-ever driver when he debuted for Toro Rosso at the 2009 Hungarian Grand Prix aged 19 years and 125 days, a record broken by Max Verstappen in Australia this year when he raced aged 17. Alguersuari completed the 2009 season with Toro Rosso and stayed for two full seasons before being dropped by the team and from Red Bull's driver programme at the end of 2011.
That left him out of Formula One aged just 21 and, despite two seasons as a test driver for Pirelli, he found his opportunities for another senior drive severely limited. He drove in eight races of the inaugural Formula E season but failed to score a podium before a health scare ruled him out of the London finale, after he blacked out during the Moscow ePrix.
During a press conference in Madrid on Thursday Alguersuari confirmed medical tests had found nothing wrong with him but said he had lost his motivation to continue racing.
"I need a change," Alguersuari said. "I've lost my love for this girlfriend. I'm 25 and I've decided to start a new chapter ... Nowadays I don't belong in racing, but I can't say it's the end either."
Alguersuari retires with 46 grand prix starts to his name, the best being a pair of seventh-place finishes in Italy and Korea in 2011.
