Lamborghini SC63 number 63 racing on track in green, white, and red livery

Grosjean and Kvyat Go It Alone at Watkins Glen

The #63 SC63 enters the Sahlen's 6 Hours with only two drivers after back-to-back retirements at Daytona and Sebring.

Romain Grosjean and Daniil Kvyat will split driving duties alone after Mirko Bortolotti was called to the Nürburgring 24 Hours with Abt Sportsline, leaving Lamborghini's LMDh prototype short-handed for a six-hour race.

The SC63's 2025 data gap

Every retirement robs the engineering team of data that informs setup changes and reliability improvements, and two straight DNFs at the biggest IMSA races have left the SC63 program chasing accumulated mileage rather than outright results.

Four Lamborghinis across three IMSA classes

Lamborghini fields cars in GTP, GTD Pro, and GTD at Watkins Glen, but the SC63 remains the bellwether — finishing cleanly on Sunday would represent genuine progress after a brutal start to 2025.
