Following in the exalted footsteps of his father, Formula One legend Michel Schumacher, Mick has made his pre-season test debut in Formula Four.Michael Schumacher’s manager called for calm and realistic expectations as the seven-times Formula One world champion’s son stepped into the media spotlight with the test on Wednesday.”My message is to be realistic with expectations,” Sabine Kehm, who is also managing the 16-year-old’s first steps on the motorsport ladder, told Reuters from the Oschersleben circuit in Germany.”This is Mick’s very first year in a formula series. He has to learn a lot of new things and make a lot of new experiences because the difference between karting and formula cars is quite big,” she added.”Give him time, don’t overreact in terms of expectations and just have him go step by step. Of course he will try and do his very best but he also has to learn a lot. This is really just the start of it.”Mick Schumacher has joined the Dutch Van Amersfoort Racing team in the eight race German Formula Four series that starts up later this month.His team mate will be Harrison Newey, 16-year-old son of multiple championship-winning Formula One’s designer Adrian Newey.Mick’s boss Frits van Amersfoort said the youngster will need time.”Of course we know that his father is a seven-time World Champion. But I want to emphasise that Mick will take the time to learn the trade of the racing driver,” he said, reports dailymail.co.uk.Mick signed a contract with van Amersfoort Racing to drive in Formula 4 in March and links up with teammate Harrison, the son of the Red Bull designer Adrian Newey.He finished second in the world, European and German kart championships last season.The teenager began karting seven years ago and this year reached German Formula 4 — a racing category used as a stepping stone by junior drivers to higher levels of international racing.While this was the first time the public were able to check out Mick in action as his pre-season practice didn’t quite go to plan as he was involved in a 100 mph crash last month.However, the crash was minor and Mick walked away from the accident uninjured.A large number of reporters and television crews were present on Wednesday, with some reports suggesting as many as 100 had sought accreditation for the test session.Michael Schumacher, the most successful Formula One driver of all time, suffered severe head injuries in a 2013 skiing accident in France and is continuing his rehabilitation at home in Switzerland.
