Dirk Mueller led the way in the first of three practice sessions for Saturday’s Northeast Grand Prix at Lime Rock Park, topping the time charts for Ford Chip Ganassi Racing.
The German took his No. 66 Ford GT to a quick lap of 50.924 seconds to go quickest of the 60-minute session, which ran largely without incident.
Mueller’s time was 0.097 seconds faster than the No. 911 Porsche 911 RSR of Nick Tandy, with the sister Ford, driven by Ryan Briscoe, third overall and in the GT Le Mans class.
The No. 912 Porsche of Earl Bamber was fourth quickest, with Jesse Krohn the best of the BMW M8 GTEs in fifth.
Kyle Marcelli led the way in GT Daytona, pedaling his No. 14 3GT Racing Lexus RC F GT3 to a quick time of 52.303 seconds.
Marcelli’s time was just 0.005 seconds faster than Alvaro Parente’s No. 86 Meyer Shank Racing Acura NSX GT3, with the No. 44 Magnus Racing Audi R8 LMS of Andy Lally just 0.025 seconds further behind in third.
The entire ten-car GTD field was separated by 0.330 seconds.
The only notable incident in the session was a brief pit lane fire for the GTD class championship-leading No. 48 Paul Miller Racing Lamborghini Huracan GT3 of Bryan Sellers.
Sellers’ car was wheeled to the garage and did not return to action in the session, with an engine change reportedly underway.
