Two days after the completion of the 2021 24 Hours of Le Mans where the World Endurance Championship (WEC) sports car series’ Hypercar class made its first run at the Circuit de la Sarthe, a major player provided confirmation for their intentions to produce a challenger for the North American equivalent of the competitive racing class. Competing as a manufacturer in the International Motor Sports Association (IMSA) Weathertech SportsCar Championship since 2017, Cadillac is looking forward into 2023 with a new car for an eagerly awaited LMDh category.

Providing only a single image of their successor to their DPi-V.R race car, Cadillac has pledged to work with race car chassis developer Dallara as well as IMSA competitors Chip Ganassi Racing and Action Express Racing in having a new vehicle ready to take the grid for the 2023 Rolex 24 at Daytona. The Cadillac LMDh-V.R. prototype features an aggressive body shape that contains many of the luxury car maker’s design cues including the marque’s iconic slim, vertical taillights. Few details of the LMDh-V.R. have been revealed but Cadillac has stated they are working on a hybrid powertrain utilizing a unique gasoline engine as well as the LMDh class’ spec electric power unit.

The most exciting prospect of the new LMDh (Le Mans Daytona hybrid) category is that new IMSA class will be allowed to compete in races organized European-based Automobile Club de l’Ouest (ACO). Starting in 2023, LMDh class machines created for the IMSA Weathertech SportsCar Championship as well as vehicles developed for in the FIA World Endurance Championship’s recently-launched Le Mans Hypercar category will be able to compete together. In essence, Le Mans Hypercar participants can run in the Rolex 24 at Daytona as well as the Twelve Hours of Sebring while LMDh cars can be entered at the 24 Hours of Le Mans.

Cadillac’s last appearance at the Circuit de la Sarthe was between 2000 and 2002 when General Motors’ luxury car marker competed in the top-ranked LMP900 category. Originally relying on a chassis developed by Riley & Scott and propelled by a twin-turbocharged 4.0-liter engine adopted from an Oldsmobile-branded powerplant used successfully in the Indy Racing League through the late 1990s, the Cadillac Northstar LMP race car faired poorly in the three outings in the 24-hour race with the best result being a ninth place finish at the 2002 event.

It’s worth noting that the era of Cadillac’s Le Mans effort coincided with a highly competitive time in the prototype sports car category. The Cadillac Northstar LMP competed against the legendary Audi R8, the Audi-drived Bentley EXP Speed 8, the front-engined Panoz roadster as well as a Chrysler/Oreca effort using a Dallara chassis. The American premium vehicle brand’s potential return for the 24 Hours of Le Mans is likely to take place under the similar competitive conditions as their last appearance with the Hypercar class. Toyota, Alpine and Glickenhaus (an American specialty car company) participated in the 2021 24 Hours of Le Mans while Peugeot and Ferrari are firmly preparing entries in the Hypercar category.

A Canadian Star Car: Red Green's Possum Van

Clip of Possum Van during a Red Green Show season 1 scene transition. It could be argued that the car someone regularly drives can be reflective of their personality. The level of character traits found in our automobiles can range from subtle to flamboyant as practicality, style, power, brand loyalty and other details are factors influencing our vehicle affection. On the big screen and silver screen, an automobile (frequently popularized as a Star Car) can be used to affirmatively to expand on a human character. Batman’s Batmobile, the Dodge Charger called the ‘General Lee’ in Dukes of Hazzard, the Volvo P1800 featured in the 1960s television version of The Saint, the Aston Martin DB5 driven by James Bond in some of the most famous spy movies are some popular examples where vehicles play a major role in reinforcing the appearance of fictional individuals. Due to the budgetary constraints of Canadian media productions, the presence of native Star Cars is rare. However, one success...

What Is A Column Shifter and Why It Is Regaining Relevance?

Eventually through the evolution of automobile design, the familiar placement for a gearshift lever was mounted on the floor. However, for a time, it was also popular to find a gear shifter behind the steering wheel attached to the steering column. The Birth of Three on the Tree Although column shifters would become synonymous with automatic transmissions, the first appearance of the gear shift behind the steering wheel came with a manual gearbox. Referred to in brochures as remote control shifting, the 1939 Plymouth introduced the shifter positioning behind the steering wheel. The novel remote control shifting ...

The 1967 Indy 500: When An STP-Sponsored Turbine Almost Changed Racing

Photo Credit: Uncredited Photographer/IMS LLC Racing has always been the ultimate proving ground for automobiles. Not only has competition promoted innovations big and small, race cars have also influenced overall vehicle appearance. At the 1967 Indianapolis 500, the STP-Paxton TurboCar fielded by the late Andy Granatelli provided a shocking example of how much racing at the speedway evolved over 56 years. Ever since the first 500-mile event was held at the 2.5-mile rectangular oval Indianapolis Motor Speedway in 1911, the winning Marmon Wasp with a rearview mirror paved the way for what would be a grand showcase of automotive development. Accompanying “The Greatest Spectacle in Racing,” advancements in automobile technology showed greater sophistication with every passing decade in the quest for more speed. During the 1920s and 1930s, American race car designer Henry Miller offered groundbreaking engines to the Indianapolis 500. Miller also gave front-wheel drive technology it...
