Castroneves takes turn at the top for Acura in second Detroit practice

A messy final IMSA WeatherTech SportsCar Championship practice session ahead of this afternoon’s qualifying was headed once again by Acura Team Penske’s Ricky Taylor and Helio Castroneves.

The duo’s ARX-05 DPi (1m22.363s) was nearly matched by Pipo Derani in his Tequila Patron ESM Nissan Onroak DPi (+0.025s) and Action Express Racing’s Filipe Albuquerque (+0.064s) in his Cadillac DPi-V.R.

Colin Braun, best among the spec P2 entries, was sixth in the the CORE Autosport ORECA 07-Gibson (+0.442s).

In GT Daytona, Jack Hawksworth’s 3GT Racing Lexus RC F GT3 (1m28.468s) improved to first in class after holding second in the opening practice session. Detroit stand-in Jeff Segal, who’s deputizing for Scuderia Corsa’s Le Mans-bound Cooper MacNeil, shadowed the Lexus (+0.184s) with his Ferrari 488 GT3, and Katherine Legge — P1 this morning in her Meyer Shank Racing Acura NSX GT3 — was third (+0.317s).

The 110-minute session fell victim to multiple red flags that consumed large chunks of time. The first came eight minutes in as Andy Lally’s Magnus Racing Audi R8 LMS GT3 streaked by the start/finish line with fire trailing from the engine bay.

The New Yorker got to Turn 1, he pulled over and jumped out unscathed. Twenty-six minutes were consumed while tending to his car and some track surface issues at another corner. Green running resumed for 17 minutes before Felipe Nasr spun his AXR Cadillac in Turn 13, tapped the wall with the rear of the car, and triggered a second red flag.

Twenty minutes later, the session resumed and despite intermittent sprinkles, it almost made it to the checkered flag without incident, but the leading Castroneves Acura stopped in Turn 10 and triggered the third red flag with eight minutes left on the clock.

With fire damage to repair, Lally reported the Magnus Audi will not return to the track on Friday.

UP NEXT: Qualifying, 5:20 p.m. ET
