OPINION: How IMSA’s DPi period made sports activities automotive racing higher


Discover a image of a first-generation Daytona Prototype, circa 2003-07, from what was then known as the Grand Am Rolex Sports activities Automobile Collection. Now put it alongside an image of a present IMSA WeatherTech SportsCar Championship Daytona Prototype worldwide (DPi) competitor — and even higher, one in every of subsequent yr’s LMDh prototypes out testing for what guarantees to be a banner 2023 season for sports activities automotive racing around the globe.

The briefest glimpse of these side-by-side pictures shortly illustrates simply how far top-level sports activities automotive racing in America has superior within the final 20 years. It’s a tremendous transformation, one which has not solely produced thrilling, engaging, fashionable racing automobiles, but in addition a radical shift in philosophy about IMSA’s place on the planet sports activities automotive hierarchy.

These early DPs have been jarring — crude, technically simplistic tube-frame chassis with pushrod V8 engines that sounded extra NASCAR than sports activities automotive. With a comically giant greenhouse (security first, it was stated), early DPs regarded like a toddler’s scrawled rendition of a Porsche 956.

The Grand Am mindset was additionally jarring, particularly as a result of American sports activities automotive racing was within the midst of a “break up” between Grand Am and the American Le Mans Collection that had the potential to be each bit as damaging because the schism in IndyCar racing between CART/Champ Automobile and the Indy Racing League. It was simple to attract parallels between Grand Am and IRL, each of which tried to chop prices by mandating low-tech, budget-minded automobiles that have been an insult to the delicate and swish machines that preceded them.

However that mindset regularly modified through the years. Daytona Prototypes received marginally extra engaging, with new generations rolled out in 2008 and ’12. Grand Am absorbed ALMS on the finish of the 2013 season, coming collectively underneath the WeatherTech SportsCar Championship banner; and after three years with third-gen DPs serving as the highest class, the DPi method that debuted in 2017 not solely restored a a lot greater stage of expertise to American sports activities automotive racing, it considerably enhanced IMSA’s credibility with the FIA and the World Endurance Championship.

It can’t be overstated how necessary DPi has been for IMSA’s development and future momentum. By pairing homologated LMP2 chassis with engines and distinctive bodywork affiliated with OEM producers, IMSA created a method that produced secure, engaging, and (comparatively) cost-effective automobiles.

DPi provided nice variety, with four-, six-, and eight-cylinder opponents, and the on-track product was shut and aggressive, because of efficient use of the Stability of Efficiency philosophy that’s now widespread in sports activities automobiles and different main types of motorsport — most notably NASCAR.

Actually, loads of of us bemoaned the “NASCAR-ification” of sports activities automotive racing when the Grand Am got here onto the scene. In spite of everything, Jim France is credited because the sequence founder, and it operates underneath the NASCAR umbrella.

Seems that wasn’t essentially a foul factor. Following the American sports activities automotive merger, NASCAR’s possession supplied monetary and organizational stability for the mixed WeatherTech Championship, and the creation of the DPi method appeased followers and producers who pined for the extra superior factory-supported prototypes from the ALMS period.

DPi’s six-year run resulted in three championships apiece for Cadillac and Acura, together with race-winning packages from Nissan and Mazda. It additionally coincided with a concentrated effort between IMSA, the FIA, and the ACO to work collectively in a extra harmonious style to unify and strengthen sports activities automotive racing on a worldwide foundation.

With that in thoughts, when IMSA started planning the following era of its top-class prototype to exchange DPi, it was finished with the intention of discovering a manner for its producers and groups to take these automobiles to the 24 Hours of Le Mans and different FIA World Endurance Championship races and compete for total victory. Equally importantly, that crossover would work each methods, equalizing automobiles constructed to FIA “Hypercar” specification to compete with the brand new IMSA automobiles by means of a collectively developed widespread gearbox and hybrid system.

That’s what sports activities automotive followers must stay up for sooner or later: IMSA’s revived GTP class makes eligible its homegrown LMDh prototypes from Cadillac, Porsche, Acura, BMW, and (becoming a member of in 2024) Lamborghini, together with WEC Hypercars from Toyota, Peugeot, and Ferrari. The primary main convergence will come at Le Mans, the place the one centesimal anniversary of the primary 24 Hours might be celebrated.

Getting again to the place we began, place an image of a 2023 IMSA LMDh subsequent to the picture of a WEC Hypercar, and so they each look modern, fashionable, and thrilling, filled with present, related, state-of-the-art expertise hidden underneath the pores and skin. The visible comparability to a boxy 2003 Grand Am Daytona Prototype is thoughts boggling.

It’s one other manner of visually demonstrating simply how far IMSA has come — not solely by way of the way it embraces far more of a world view by way of the connection between expertise and sports activities automotive racing, but in addition in the way in which that American sports activities automotive racing instructions far more respect on a global stage than it has at any time prior to now.

The DPis will race another time subsequent weekend within the twenty fifth annual Motul Petit Le Mans at Michelin Raceway Highway Atlanta. They’ll little question placed on an excellent present, however for IMSA — and for sports activities automotive racing followers around the globe — the most effective is but to come back.
