Helio Castroneves has a theory on why nobody can seem to catch IndyCar Series leader Scott Dixon.

"Scott seems to have a V12 engine," Castroneves said after watching Dixon grab the pole for the Meijer Indy 300 on Saturday at Kentucky Speedway. Dixon easily earned his fifth pole of the season, averaging 218.968 mph during his four-lap turn around the 1.5-mile oval, his Target Chip Ganassi car snapping Team Penske's streak of three consecutive poles at the track. Vitor Meira will start outside the front row with a four-lap average of 218.409.
