Callaway Competition just pulled off its third victory in a row in the hotly contested 2013 ADAC GT Masters Championship. Rounds 11 and 12 took place at the tight 3.4 kilometer (2.13 mile) Lausitzring circuit located in Northeast Germany. For race #1 the Corvette driven by Diego Alessi qualified fifth behind three Porsches and one Audi R8. Alessi turned a 1:21.480 and the fastest Porsche won the pole with a 1:21.281. This was an amazing performance considering they carried extra weight for their double victory at the Red Bull Ring. When the green flag fell, the pole-winning Porsche was passed by the second place Audi R8. The Porsche dove to the inside at the end of lap one to retake the lead only to be squeezed into a curb at the turn. The Porsche flew into the air leaving a trail of debris all over the track and damaging the track. The race was red-flagged for 20 minutes to repair the damage to the turn. When the race restarted Alessi dove into the pits to make the Corvette's mandatory driver change. When Keilwitz returned to the track they were in the lead closely followed by a BMW. Somehow Keilwitz held off the BMW to score Corvette's third victory in a row. Remo Lips and Lennart Marioneck won the Amateur category driving their Callaway Competition Corvette. After the race Diego Alessi said, “Our pit strategy was the key to our success. Daniel drove a good second half of the race and took the victory.”
Keilwitz qualified fourteenth for race two with a time of 1:21.299 behind the Polarweiss SLS Mercedes. Porsche won the pole again with a 1:20.610. Keilwitz and the Mercedes carved their way up through the field. At one point Keilwitz passed the Merc to take fourth place. However, the SLS was able to re-pass the Corvette under braking to finish fourth with Keilwitz fifth. Lips and Marioneck finished third in the Amateur category in their Callaway Corvette. With four races remaining Alessi and Keilwitz lead the championship with 136 points. Porsche is second with 133 points BMW is third with 120 points. Rounds 13 and 14 will be held at the Slovakia Ring in the Slovak Republic 9/13-15/2013. This 5.9 kilometer (3.6 miles) circuit is noted for its high speeds, which should suit the Corvette's brute power.
