General Motors vient de présenter la nouvelle CT4-V Blackwing, la version la plus radicale et la plus sportive de la « plus petite » voiture de la marque Cadillac. Quelques jours après l’arrivée des 24h Daytona et à quelque jours de l’inénarrable Super Bowl ce weekend ! Présentation
Cadillac was formed from the remnants of the Henry Ford Company.
After a dispute between Henry Ford and his investors, Ford left the company along with several of his key partners in March 1902. Ford’s financial backers William Murphy and Lemuel Bowen called in engineer Henry M. Leland of Leland & Faulconer Manufacturing Company to appraise the plant and equipment in preparation for liquidating the company’s assets.
Instead, Leland persuaded the pair to continue manufacturing automobiles using Leland’s proven single-cylinder engine. A new company called the Cadillac Automobile Company was established on 22 August 1902, re-purposing the Henry Ford Company factory at Cass Street and Amsterdam Avenue.
It was named after French explorer Antoine Laumet de La Mothe, sieur de Cadillac, who had founded Detroit in 1701.
Le 24 juillet 1701, Antoine de Lamothe-Cadillac fonde le fort Pontchartrain et la paroisse Sainte-Anne sur la rive du nord de la rivière Détroit, dans la région des Grands Lacs d’Amérique du Nord.
Les prévisions d’Antoine de Lamothe-Cadillac se concrétisent après son départ de la Nouvelle-France. Ainsi, Jean Baptiste Le Moyne de Bienville fonde La Nouvelle-Orléans à l’embouchure du Mississippi en 1718.
Le détroit devient un lieu stratégique. Pour défendre son accès, le fort Niagara est construit en 1725 sur la rive droite de la rivière entre les lacs Érié et Ontario et, en 1726, le poste d’Oswego est fortifié sur le lac Ontario.
Rebaptisé ‘Detroit’, le Fort Pontchartrain, idéalement situé entre les grands lacs et les bassins fluviaux, devient un grand centre industriel au XIXe siècle, puis la capitale de l’industrie automobile américaine au XXe siècle ; surnommé ‘The Motor City’,
Détroit est en outre devenu le berceau de la musique soul noire dans les années 1960 sous le règne du label ‘Motown’.
The Cadillac Automobile Company merged with Leland & Faulconer Manufacturing, forming The Cadillac Motor Company in 1905.
From its earliest years, Cadillac aimed for precision engineering and stylish luxury finishes, causing its cars to be ranked amongst the finest in the United States. Cadillac was the first volume manufacturer of a fully enclosed car, in 1906.
Cadillac participated in the 1908 interchangeability test in the United Kingdom, and was awarded the Dewar Trophy for the most important advancement of the year in the automobile industry.
In 1909, Cadillac was purchased by the General Motors (GM) conglomerate.
Cadillac became General Motors’ prestige division, devoted to the production of large luxury vehicles.
The Cadillac line was also GM’s default marque for « commercial chassis » institutional vehicles, such as limousines.
It became positioned at the top of GM’s vehicle hierarchy, above Buick, Oldsmobile, Oakland, and later, Chevrolet.
In 1912, Cadillac was the first automobile manufacturer to incorporate an electrical system enabling starting, ignition, and lighting.
In 1886, the St. Johns & Halifax River Railway arrived in Daytona. The line would be purchased in 1889 by Henry M. Flagler, who made it part of his Florida East Coast Railway.
The separate towns of Daytona, Daytona Beach, Kingston, and Seabreeze merged as « Daytona Beach » in 1926, at the urging of civic leader J.B. Kahn and others. By the 1920s, it was dubbed « The World’s Most Famous Beach ».Daytona’s wide beach of smooth, compacted sand attracted automobile and motorcycle races beginning in 1902, as pioneers in the industry tested their inventions.
It hosted land speed record attempts beginning in 1904, when William K. Vanderbilt set an unofficial record of 92.307 mph (148.554 km/h). Land speed racers from Barney Oldfield to Henry Segrave to Malcolm Campbell would visit Daytona repeatedly and make the 23 mi (37 km) beach course famous.
Record attempts, including numerous fatal endeavors such as Frank Lockhart (Stutz Black Hawk, 1928) and Lee Bible (Triplex Special, 1929), would continue until Campbell’s March 7, 1935 effort, which set the record at 276.816 mph (445.492 km/h) and marked the end of Daytona’s land speed racing days.
On March 8, 1936, the first stock car race was held on the Daytona Beach Road Course, located in the present-day Town of Ponce Inlet.
In 1958, William France Sr. and National Association for Stock Car Auto Racing (NASCAR) created the Daytona International Speedway to replace the beach course.
The CT4 is a compact executive sedan manufactured and marketed by Cadillac. It replaced the Cadillac ATS and sits below the CT5 in Cadillac’s lineup. The base engine is a 2.0-liter turbocharged four-cylinder (I4).
CT4-V Blackwing is a higher performance version of the CT4-V powered by a 3.6-liter twin-turbocharged V6 engine producing 472 hp and 603 Nm of torque. The twin turbos made with titanium-aluminide turbine wheels.

During the 2021 24hours at Daytona, Cadillac shared a sneak peek of the 2022 CT4-V Blackwing
“V-Series Blackwing stands for the very highest level of execution from Cadillac and offers a distinctly American vision of performance: incredible power and luxurious craftsmanship, with absolutely zero compromise.”
“We looked to our championship-winning racing heritage and brought an uncompromising eye for detail to create two cars that elevate the V-Series experience.”Brandon Vivian, executive chief engineer, Cadillac
Design extérieur Cadillac CT4-V Blackwing
Leveraging a Cadillac racing history that began in 1949 and has seen sustained success over the last two decades, the V-Series Blackwing models were developed with driver engagement and performance at the top of mind.
Les faces avant et arrière ont été modernisées avec des grilles secondaires plus grandes, un séparateur avant plus efficace, un spoiler arrière et des extensions de bas de caisse plus musclées qui renforcent généralement le profil du CT4.

The turbos’ low-inertia (titanium-aluminide) turbine wheels enable more precise and responsive application of torque throughout the rev range.
- Most powerful and fastest Cadillac in the subcompact class.
- Air intake restriction is improved by 39 percent vs. ATS-V.
- Turbocharger compressors matched for peak efficiency at peak power for optimal track performance.
- Titanium connecting rods (manual transmission only) and revised crankshaft counterweights reduce main/rod bearing reciprocating loads.
- Re-targeted piston oil squirters, which direct engine oil at the bottoms of the pistons, for improved temperature control.
- The manifold-integrated water-to-air charge cooling system contributes to more immediate torque response.
- Airflow routing volume is reduced by 60 percent when compared to a conventional design that features a remotely mounted heat exchanger.
- Rare for sport sedans, today, a six-speed TREMEC manual transmission is standard. Custom parts via 3D printing.

V-Series Blackwing combines the fourth generation of Magnetic Ride Control (MR 4.0), with improvements to the front and rear suspension systems. Stiffer spring rates, unique hollow stabilizer bars, higher-rate bushings and more enable a driving experience that isolates the driver from road imperfections, while also providing a precise, engaging connection with the road.
springs and bushings are stiffer, stabilizer bars are now hollow, and GM’s Alpha 2 platform is upgraded for improved rigidity across the board.
