Helio Castroneves closed out the two-day IndyCar promoter test at the top of the timesheets as average speeds broke the 190 mph barrier at Phoenix International Raceway.
Castroneves led the way on Friday behind the wheel of the #3 Penske as he set a new unofficial lap record at Phoenix, only to go faster still in Saturday evening's session.
The Brazilian set a fastest time of 19.2735 seconds at an average of 190.894 mph in the fourth and final practice session, bouncing back from a problem that had limited his running in the afternoon.
"We had a little issue with the Hitachi car in the first session, but were able to take full advantage of the second one," Castroneves said.
"The car seemed to be very solid in qualifying trim and we were able to jump into race mode. It's going to be fast and non-stop. The Phoenix fans are going to have a heck of a race."
Castroneves' lap was enough to edge out Penske teammate Simon Pagenaud who had gone fastest in the afternoon session with a time of 19.2884 seconds, which was good enough for P2 at the end of the day.
Ed Carpenter Racing enjoyed a strong showing at Phoenix as Josef Newgarden and team owner Ed Carpenter finished third and fourth overall, while Marco Andretti ended the day as the leading Honda-powered driver in fifth for Andretti Autosport.
Tony Kanaan bounced back from a quiet Friday to end up sixth for Chip Ganassi Racing ahead of Penske's Will Power. Ryan Hunter-Reay finished eighth, while 2015 championship protagonists Scott Dixon and Juan Pablo Montoya rounded out the top 10.
