Detroit IMSA: Derani, Legge lead opening practice

Derani, who took pole here last year driving the Nissan DPi for the now-defunct ESM Racing team, eclipsed that time by some 1.7sec as the Michelins made their mark on the 2.35-mile 14-turn course.

The Brazilian set a 1min20.583sec lap to better the best effort of Helio Castroneves in the #7 Acura Team Penske ARX-05 by a quarter-second.

Filipe Albuquerque in the second AXR Cadillac was third ahead of the second Acura of Dane Cameron.

Jordan Taylor was fifth-fastest in the WTR Cadillac, one second off the ultimate pace, with Colin Braun sixth in the CORE autosport-run Nissan DPi.

Tristan Vautier and Simon Trummer were seventh and eighth in the JDC Miller Motorsports Cadillacs, but the squad had a torrid 90-minute session.

Trummer struck the wall causing the first red flag, while Vautier’s teammate Misha Goikhberg also caused a red when he went into the tires – an incident that also involved Matt Plumb in Compass Racing’s beautiful McLaren 720S.

Legge’s top time in the MSR Acura was a quarter-second ahead of last year’s GTD polesitter, Bryan Sellers in the Paul Miller Racing Lamborghini Huracan.

Zachary Robichon’s best effort in the Park Place Motorsports Porsche 911 GT3 R was a mere 0.037sec slower and 0.36sec clear of Richard Heistand in the #14 AIM Vasser-Sullivan Lexus RC F.
