Challenging weather conditions result in surprise winners Gripping races, delighted drivers on winners’ rostrums and contented fans – the premiere of the ADAC Masters Weekend 2011 in the Austrian town of Spielberg was a resounding success for everyone involved. In total, there were nine races at the fan-friendly motorsport venue from 12 to 14 August, featuring the super sports cars of the ADAC GT Masters, up-and-coming racing drivers in the ATS Formula 3 Cup and Formel ADAC, and the ADAC PROCAR touring cars. Saturday proved to be especially challenging as the heavens opened, turning the Red Bull Ring, which only opened in May, into something resembling a swimming pool. This resulted in overtaking manoeuvres en masse and a few winners who nobody would have reckoned with at the start of the day.ADAC GT Masters: fourth win of the season for Stuck brothersAustrian brothers Ferdinand and Johannes Stuck went on a rollercoaster ride of emotions in front of an Austrian audience on the fifth racing weekend of the ADAC GT Masters. The Lamborghini duo had to pull out of the first of two races in the “super sports car league” early following a collision in the early stages of the race. But in the second race, the two Austrians gave their fellow countrymen who filled the grandstands of the Red Bull Ring something to cheer about when they secured a comfortable victory with a lead of a good eight seconds after 38 laps. With 25 points for the win, the two brothers have now taken over at the top of the leader board. The BMW-ALPINA duo Alexandros Margaritis (GR) and Dino Lunardi (F) are behind them in second place overall. They came sixth on the first day of racing and then secured second place on the second day, finishing ahead of the two Austrian drivers Dominik Baumann and Hari Proczyk (Mercedes-Benz SLS AMG). The surprise winners of the first race, which was plagued by rain, were Norbert Siedler of Austria and Christian Engelhart of Germany racing for MRS Team PZ Aschaffenburg in a Porsche 911, ahead of Andreas Zuber/Lance David Arnold in a Mercedes-Benz SLS AMG. The most impressive sporting performance came from Christopher Haase and Andreas Simonsen in their Audi R8 for Phoenix Racing Pole Promotion, who crossed the finishing line third, having started in 24th place.ATS Formula 3 Cup: two wins help Stanaway extend his overall leadThe New Zealander Richie Stanaway proved that he is in excellent form this year once again on the sixth racing weekend of the ATS Formula 3 Cup. Even in the two timed practice sessions, the series rookie who races for Van Amersfoort Racing made the most of every opportunity and managed to clinch pole position for both races. In the first race, which had to be started with the safety car because of the wet conditions on the racetrack, Stanaway chose to shake off his pursuers and achieved a comfortable victory after 18 laps, with a four-second lead over Marco Sörensen (DK) and Hannes van Asseldonk (NL). By the time of the second race, held on Sunday, the racetrack had dried out for the 18 drivers. But the weather conditions made no difference to Richie Stanaway either way, as he once again started in pole position and came in first. Stanaway only briefly relinquished his lead to Marco Sörensen for a couple of bends near the start of the race. At the end of 21 laps, the three same drivers – Stanaway, Sörensen and van Asseldonk – stepped onto the winners’ rostrum as had done the previous day. This year’s ATS Formula 3 Cup will no doubt be decided between Stanaway (117 points) and Sörensen (92 points).Formel ADAC: Dane Kristensen unstoppable in SpielbergThe Dane Kean Kristensen finished tenth in no less than seven of the twelve races in the first half of the Formel ADAC series, the racing series for up-and-coming drivers. This made his impressive performance at the series premiere of the Red Bull Ring all the more surprising. Kristensen came second in the first of three races, achieving a season best on a racetrack that was slightly damp. And things got better from there. The race organisers hit the apparent winner and overall leader Pascal Wehrlein (D) with a 30-second drive-through penalty at the end of the race for having picked up the pace too soon after the initial safety car phase. As a result, Kristensen moved up to first place, ahead of Mario Farnbacher (D) and Emil Bernstorff (GB). Conditions were dry for the second race on Sunday – and Kristensen was unstoppable once again, securing his second victory ahead of Bernstorff and Wehrlein. In the third and final race, the only driver to pip Kristensen to the post was his Russian Motopark colleague Artem Markelov. Third place went to Farnbacher. This result is only provisional, however, because one team has lodged an appeal.ADAC PROCAR: Leidinger clinches two victories in AustriaThe ADAC PROCAR at the Red Bull Ring was comfortably dominated by Johannes Leidinger (D) in his BMW 320si. He started the first race in second place and managed not only to overtake his Division 1 colleague Jens Weimann (D) in the space of twelve laps, but also to maintain a lead of a good nine seconds right up to the finishing line. The third fastest driver was Nils Mierschke (D) with a Ford Fiesta ST from Division 2. The second race was likewise decided between Leidinger and Weimann. But the outcome was not so clear-cut this time and Leidinger finished with a lead of 0.4 seconds after twelve laps. The double victory was therefore in the bag. Third place overall once again went to the top Division 2 driver, Nils Mierschke.TV highlights on kabel eins, SPORT1 and MotorsTV‘kabel eins’ channel shows a highlight magazine programme of the Formula races shortly after midnight on race Sunday. ‘SPORT1’ broadcasts highlights of the events at the Red Bull Ring on 20 August from 13:00. ‘MotorsTV’ shows a recording of the all the ADAC GT Masters races in full length (16 August from 21:00, 17 August from 07:00 and 18 August from 14:00).
