Scott Dixon and Honda showed they are ready to contend for victory in the 108th Indianapolis 500 presented by Gainbridge by leading the way in the final practice session on Carb Day at Indianapolis Motor Speedway.

Six-time IndyCar champion Dixon topped the speed charts with a lap of 227.206 mph in the No. 9 PNC Bank Chip Ganassi Racing Honda. It marked the ninth time in the last 10 years that the 2008 Indy 500 winner ended up among the top four on the practice speed charts heading into race day.

While Chevrolet drivers swept the top eight starting spots in last weekend’s qualifying, including a Team Penske lockout of the front row, it was Honda’s turn to shine on Carb Day. Honda-powered cars claimed seven of the top 10 speeds in the final two-hour practice, signaling they may have closed the gap for Sunday’s 200-lap race.

Four-time Indy 500 winner Helio Castroneves has his sights set on an unprecedented fifth victory after ending up second on the speed chart at 226.939 mph in the No. 06 Cliffs Honda for Meyer Shank Racing. The 49-year-old Brazilian is starting 20th on Sunday.

Pato O’Ward was the top Chevrolet driver in fourth at 226.666 mph in the No. 5 Arrow McLaren entry. His teammate Kyle Larson, the highest-starting rookie in fifth, got valuable practice after his car ran out of fuel and had to be towed in.

Pole sitter Scott McLaughlin and the Team Penske Chevrolets were mired well down the speed charts, with McLaughlin 20th, Will Power 21st and defending winner Josef Newgarden 32nd out of the 33 cars.

In the annual One Stop to Start Pit Stop Challenge, Newgarden and the Penske crew won their record-extending 19th title by sweeping Arrow McLaren in the best-of-three final round. Newgarden’s crew earned $50,000 for the win.

Now all that’s left is Sunday’s 200-lap race (12:45 PM ET, NBC), where Honda and Chevrolet will settle which manufacturer has the upperhand at Indy this year. Dixon is confident he can drive up from his 21st starting spot to contend for his second Indy 500 victory.
