Conor Daly used a combination of increased turbo boost and drafting to set the fastest lap of the month in Practice 4 as preparations for the 103rd Running of the Indianapolis 500 continued at the Indianapolis Motor Speedway.
- Results: 2019 Indianapolis 500 Practice 4
Daly’s superior speed came at the end of the seven-hour session during an eight-minute period of green-flag running that followed a yellow for track inspection.
The 231.704 mph lap by Daly in his No. 25 Andretti Autosport Honda was nearly a full mile per hour quicker than the previous best lap, set by teammate Marco Andretti early in the session on just his second lap of the day. Despite having the fastest overall speed, Daly ranked 22nd on the all-important no-tow speed chart.
Andretti’s 230.851 mph effort dropped to second fastest overall while his best no-tow lap of 239.382 mph was the day’s seventh best.
Takuma Sato added a third Honda to the top three while Ed Carpenter Racing’s Spencer Pigot was the fastest Chevrolet representative in fourth.
On his penultimate lap, Ryan Hunter-Reay lapped the 2.5-mile oval with a tow-assisted speed of 230.466 mph, good enough for his DHL Honda to land fifth overall and be second fastest for the Japanese manufacturer. The remainder of the top 13 was locked out by Chevrolet with all but the slowest of the group over 230 mph.
Ed Jones repeated the feat he accomplished in Practice 3 of having the fastest no-tow speed. The 230.106 mph lap ranked Jones ahead of his team owner Ed Carpenter whose 229.879 mph effort was second fastest without a tow.
Alexander Rossi, Will Power and Simon Pagenaud completed the no-tow top five, adding representation from Andretti Autosport and Team Penske.
Fernando Alonso, back on track after crash damage kept him from turning laps Thursday, ended the day ranked 24th overall and 31st without a tow.
Patricio O’Ward, driving a backup car after crashing Thursday, turned 38 laps but managed only 227.513 mph. The speed relegated him to 34th fastest overall.
There were six yellow-flag periods during Practice 6 but only one for contact. Fifty-one minutes after the start of the session, Kyle Kaiser’s No. 32 Juncos Racing Chevrolet experienced a half spin in Turn 3 before making hard left-side contact with the SAFER Barrier. The car then turned on its side and nearly flipped before coming down on its four wheels. Secondary contact with the inside SAFER Barrier in the north short chute caused additional damage. Kaiser was uninjured and is cleared to drive but must wait for the Speedway, Indiana-based team to piece the wrecked machine back together.
The first day of qualifications will begin with practice from 8–9:30 a.m. EDT Saturday. Single-car qualifying runs of four laps each will follow at 11 a.m. to set positions 10 through 30 on the race grid and determine the drivers who will participate Sunday in the Fast Nine and Last Row qualifying sessions.
