Marko admits Red Bull's error: 'It would be helpful if we had it'

On the first day of the Las Vegas Grand Prix weekend, Max Verstappen and Sergio Perez felt uncomfortable in the RB20. Verstappen complained of balance problems and, in particular, could not keep pace over one lap. Helmut Marko confirmed to GPblog and others that Red Bull Racing may have made the wrong choice with a different rear wing. However, the advisor is hopeful that the Austrian team can make a step forward before qualifying.
