Madrid's new semi-urban circuit, the Madring, came through its first day of real Grand Prix conditions on Friday. The sessions delivered excitement and a layout that tested the drivers hard, though the day also brought problems, from chaos around the venue to stretches where the broadcast signal cut out. Even with the hiccups, the track gave a first taste of what it can offer at the Spanish Grand Prix. The rest of the weekend will show whether the teething troubles get sorted out.
