Unveiled in January 2024, the refreshed 2025 Cadillac CT5-V Blackwing represents the fourth model year for the ultra high-performance luxury sedan, and a new limited-edition variant has been revealed as part of the ongoing Collector Series portfolio.

The 2025 Cadillac CT5-V Blackwing Le Monstre Edition was unveiled as the latest limited-run variant of the nameplate, and only 101 units will be produced as a hat tip to the 101st anniversary of the original Le Mans race. The car itself pays homage to the 1950 Cadillac Le Mans race car, which was nicknamed “Le Monstre” as it was entered in the 24 Hours of Le Mans race that year. It competed alongside another Cadillac race car, nicknamed “Petit Pataud,” which was a more mildly modified Cadillac Series 61 Coupe.

At the time, Le Mans race rules permitted participants to rebody a stock chassis, and the race car looked nothing like the Cadillac Series 61 Coupe it was based on. Under the unusual-looking bodywork, created to reduce weight and improve aerodynamics, lurked a 331 cubic-inch V8 with five carburetors, rated at 160 horsepower. Le Monstre could hit a top speed of 130 mph, 13 mph faster than Petit Pataud.

Le Monstre finished the race just behind 10th-place Petit Pataud, after its driver slammed into a sand bank on the second lap, losing precious time. However, the wedge-shaped race car managed to climb its way back up from 35th to 11th place during the race.

As for the 2025 Cadillac CT5-V Blackwing Le Monstre Edition, it boasts an exclusive Magnus Metal Frost paint job, a Stormhawk Blue carbon fiber package and Royal Blue brake calipers. A decal sporting the number 2 and a U.S. flag adorns the lower portion of the front doors, while the inscription Le Monstre is found on the carbon fiber side skirt just below the rear doors.

Inside, the Le Monstre Edition features two exclusive colorways, Jet Black/Phantom Blue and Sky Cool Gray/Phantom Blue, along with Santorini accents and blue seat belts. Laser-etched door sill plates and a unique 3D printed manual transmission shifter medallion are also part of the package. As with all 2025 Cadillac CT5-V Blackwing units, the cabin also features a 33-inch LED display incorporating the digital driver instrument panel and the infotainment system touchscreen, running a Google built-in interface.

Production of the 2025 Cadillac CT5-V Blackwing Le Monstre Edition is planned for early 2025, and more information will be released in the coming months. The brand also revealed the 2025 Cadillac CT4-V Blackwing Petit Pataud Edition, commemorating the other 1950 Le Mans race entry, of which only 50 units will be available.

The Le Monstre Edition follows previous Collector Series cars, including the 2024 Cadillac CT5-V Blackwing Special Edition, the 2023 Cadillac CT5-V Blackwing 120th Anniversary and the introductory 2022 Cadillac CT5-V Blackwing Collector Series.

As a reminder, the 2025 Cadillac CT5-V Blackwing cradles the supercharged 6.2L V8 LT4 gasoline engine, delivering 668 horsepower and 659 pound-feet of torque. All CT5 variants ride on the GM Alpha 2 platform.
