Corvette, Ford and Porsche were each represented at the head of the GT Le Mans field in the second one-hour practice session during preparations for the Northeast Grand Prix at Lime Rock Park.

Antonio Garcia lapped the 1.5-mile road course in 50.939 seconds in the early stages of the afternoon outing to put Corvette Racing’s No. 3 car atop the 18-car field of only GT machinery.

After leading the first practice, the No. 66 Ford GT of Chip Ganassi Racing was third thanks to a lap from Joey Hand that was within 0.062 seconds of Garcia’s time. Laurens Vanthoor, only 0.117 seconds further back, was third in the No. 912 Porsche 911 RSR to contribute a third marque to the top three.

A mechanical issue related to the clutch kept Ganassi’s No. 67 Ford from being competitive in Practice 1 but Richard Westbrook ensured the car showed its speed in Practice 2 with the fourth-fastest lap. Westbrook’s quickest lap was a minuscule 0.003 seconds quicker than that of Patrick Pilet in the second Porsche.

Both BMW Team RLL cars were sixth and seventh ahead of the second Corvette C7.R which was last despite its sister car leading the class.

Lally Leads GTD in Magnus Audi

Having won at Lime Rock last time he visited the track with Magnus Racing, Andy Lally put the team’s Audi R8 LMS GT3 atop the GT Daytona running order in Practice 2.

Below the Audi on the timesheet is a series of Ferrari, Lexus, Porsche, Mercedes-AMG and Acura machinery that put six of the seven manufacturers in the class in the top six positions.

Gunnar Jeannette and Dominik Baumann were the second- and third-fastest drivers with Baumann lapping 0.328 seconds in arrears of Lally on his best lap in the No. 14 Lexus RC F GT3. Just 0.330 seconds split all 10 GTD cars in Practice 1, which proved to be tighter.

Robby Foley, driving the BMW M6 GT3 of Turner Motorsport, was ninth and 0.008 seconds away from ensuring the seven manufacturers were included in the top seven.

The second 3GT Racing Lexus was last for the second consecutive session with Jack Hawksworth’s quickest lap being 0.865 seconds off Lally’s class-leading pace.

The championship-leading Lamborghini Huracan GT3 of Paul Miller Racing skipped Practice 2 as the team was replacing the engine following a fire in pit lane during Practice 1.

A third hourlong practice session at 4:55 p.m. EDT will conclude Friday’s IMSA WeatherTech SportsCar Championship action in Connecticut.
