Name that mystery driver

Gelles Racing Engineer Gerald Tyler has been working with elite German driver Maximilian Götz and F-1 experienced engineer Rodolfo Perdomo is working with American Skip Barber graduate Richard Heistand. “Maxi and Richard are doing great, follows Gelles; both are training extremely hard at Jim Leo’s Pit-Fit Training Academy in Indy. Luis Mussi did an outstanding job at Belle Rose, Louisiana. We also recently tested Alan Sciuto, Tim Bridgeman and South African Gavin Cronje. Tim pummeled the overall track record at Belle Rose last week in his Gelles Swift .016a and another very quick one who wants to remain anonymous."
