DAYTONA BEACH, FLA.—With just one race on the books, it's probably too soon to declare this the dawn of a new golden era in racing, but that thought was on many minds at last weekend's spectator-packed Rolex 24 at Daytona. The grueling 24-hour race is the season-opening event for the WeatherTech Sportscar Championship, and 2023 saw the introduction of a new class of hybrid prototype race cars called GTP (for Grand Touring Prototype).

The crowds were heavier than ever, buoyed by the debut of the new machines, which put on a good show. And the complicated new energy-based pit stop formula didn't appear to present anyone any trouble.

The same can't be said for the race itself. Twenty-four-hour racing is hard —I speak from some experience—and making it to the end should be, and is, a challenge. A 24-hour race as the first race of the year for all-new cars is even more difficult, despite the thousands of miles each car covered in testing over the past few months. As such, some feared we might be in for a repeat of 2003; that year saw a new prototype class introduced, the best of which finished 24 laps behind the winning car, a racing version of a Porsche 911.

IMOLA, ITALY—After a break of 50 years, Ferrari is returning to top-level endurance racing with a new hybrid prototype race car. It's called the 499P, and in 2023 Ferrari will campaign a pair of cars in the World Endurance Championship, a series with the 24 Hours of Le Mans as its crown jewel.

As I've written before , 2023 is going to be an exciting time for fans of prototype racing. After the cubic megabucks-era of LMP1h collapsed under the weight of unsustainable budgets , the top class of the World Endurance Championship has spent a few years in the doldrums as Toyota faced minimal opposition from much smaller teams. But the Automobile Club de l'Ouest (which runs the Le Mans race) has a new ruleset now, called LMH (Le Mans Hypercar), designed to attract the interest of automakers by keeping costs sane—€30 million versus the €80-200 million that LMP1h cost—and, with less reliance on aerodynamic downforce , allowing for a closer visual link to their road-going products.

And so far, it's working. Toyota was first to LMH with its GR010 , followed by boutique manufacturer Glickenhaus, then this year saw Peugeot ease its way back into to endurance racing with its new 9X8 —still not sporting a rear wing—ahead of a full campaign in 2023. But none of those brands have quite the same magic as Ferrari. Even though it last won Le Mans outright in 1965, it still has more of those overall wins (nine) than Toyota (five) and Peugeot (three) combined, trailing just Audi (13) and Porsche (19).

DAYTONA BEACH, FLA.—Car companies like to keep new models far from prying eyes during the development process. That goes doubly so when they’re going racing, like Porsche is with its new 963, which made our invitation to watch the car test on Friday, while still in development, a rare chance to watch expertise at work. Doubly so considering that Porsche's partner with the 963 is Penske Racing, an organization that has racked up more than 600 wins across a range of disciplines over the past 56 years.

The 963 has been built to win the 24 Hours of Le Mans and endurance races like it and will compete next year in IMSA's new GTP category as well as the FIA WEC's Hypercar class. Built to a rule set known as LMDh , it's more of a collaboration than the Porsche crest on the nose might lead you to expect. Multimatic in Canada provides the car's carbon-fiber spine, or chassis. Xtrac supplies the transmission, Williams Advanced Engineering provides the lithium-ion traction battery, and Bosch is responsible for the electric motor/generator unit, all three of which are tightly packaged together.

But Porsche has built the twin-turbocharged 4.6L V8, which traces its roots back to the mid-2000s RS Spyder race car, with a road-going derivative also found in the 918 Spyder hypercar. Power is capped at 680 hp (500 kW) for the internal combustion engine and hybrid system working together and is measured by sensors to ensure no one gets over-creative.
