The SC63's 'Evo Joker' Upgrade Proved This Lamborghini Can Fight — Right as Time Runs Out

A new rear suspension transformed the SC63 at Indianapolis, but the program's future hangs in the balance.

Edoardo Mortara and Romain Grosjean shared the #63 Lamborghini SC63 at Indianapolis Motor Speedway for the penultimate round of the 2025 IMSA WeatherTech SportsCar Championship, and for most of the six-hour race, the result looked like it would finally match the car's pace.

The rear suspension fix deployed through the 'Evo joker'

Lamborghini CTO Rouven Mohr acknowledged that the SC63's rear suspension carried weaknesses in kinematics and kinematic stiffness, issues the engineering team identified but deliberately delayed addressing in order to collect more data.

Four-tenths off the ultimate pace and closing

Lamborghini says the car was roughly four-tenths of a second off the ultimate best pace before qualifying, and at one point during the race, all six IMSA GTP manufacturers occupied the top six positions.

A likely top-five finish erased in the final hour

Contact with a lapped Porsche pitched Grosjean onto the grass, and a late full course yellow wiped out the recovery strategy, leaving the SC63 to finish 10th after running as high as fifth.

Lamborghini's GT effort at Indianapolis

The Huracán GT3 EVO2 continues to be Lamborghini's most consistent racing platform, and its replacement by the Temerario-based GT3 car will be the next major chapter for Squadra Corse's customer racing operation.

No WEC in 2025 and no confirmed grid spot for 2026

Lamborghini confirmed it will not contest the 2025 FIA World Endurance Championship season, and reports indicate the SC63 will not be on the grid in 2026 for either WEC or IMSA.

Engineering lessons that carry forward

The Temerario already pairs a twin-turbo V8 with hybrid electric motors, and the suspension and aero lessons learned from two seasons of prototype racing do not simply disappear when a program pauses.

Petit Le Mans — the SC63's last race for the foreseeable future

The 10-hour Petit Le Mans at Road Atlanta closes out the 2025 IMSA season and the SC63's competitive life for the foreseeable future, making it the last chance to measure how much of the car's hard-won engineering finds its way into the road cars that follow.
