| Sebastien Bourdais |
With cooler temperatures, and the Hondas towing a parachute around the track with their closed off butt bumpers, Chevys again topped the times in the third practice for the IndyCar Toronto Grand Prix with the top-5 speeds.
As he did in opening practice on Friday, Sebastien Bourdais was fastest at 1m00.603s, 2/10ths faster than fellow Frenchman Simon Pagenaud at 1m00.871s.
Will Power, Helio Castroneves and Scott Dixon rounded out the top-5.
The fastest Honda was Jack Hawksworth in 6th, only 0.44 sec behind Bourdais. 1-second covered the top-18 drivers.
