Jim Hall’s Fingerprints Are All Over Racing Today

FORT WORTH, Texas – It’s been more than a decade since an open-wheel car owned by Jim Hall has occupied space in an IndyCar Series garage.

But even as the cars have changed over the years, the innovations that the now 77-year old Hall and his team manufactured during the 1960s through the 1980s are still present today. Not only the wings and ground effects, but also Hall’s methodology of combining science and engineering to make a race car go faster.

Walking the garage area at Texas Motor Speedway last weekend at the Firestone 550, the descendants of those innovations were visible everywhere; even now Hall’s work is mentioned with a little bit of awe.

“He was phenomenal,” said Mario Andretti, former Indy 500 winner and Formula One World Driving Champion. “What he did is being enjoyed now in modern times. He was so far ahead of the curve with the Chaparral in every way.”

Hall’s innovations have been well-chronicled, in fact, the stuff of sports car racing lore. To that end, the innovations that brought him so many victories in domestic and international sports car and Indy car racing are on display at the Petroleum Museum of the Southwest in his hometown of Midland. It remains amazing to realize that many of those tweaks were created inside a small shop compound on Rankin Highway, and tested on Rattlesnake Raceway just outside Hall’s office door.

“What I applaud is his vision and really thinking outside the box,” Andretti said.

Ground effects are common on all race cars today, and so are wings. Innovations such as lightweight, carbon fiber body pieces seen first in sports car racing have become common components on high-performance street cars.

Even now, though, people know it was Hall who came up with many of the ideas that are common in regards to aerodynamics in open-wheel racing.

“It’s basics,” said Fort Worth’s Johnny Rutherford, who drove the famous “Yellow Submarine” Chaparral 2K to victory in the 1980 Indy 500. “The ground effects or the aerodynamics of a race car body, it’s not black magic. It was something that had to be discovered. You put a flap up on a race car, that’s drag. That’s going to slow you down. But if you do it in such a manner where it’s lift over drag, it’s is a plus, then you can utilize it. That’s what Jim got into.”

Many talk about the Chaparral 2K that Rutherford drove to his third victory at Indianapolis Motor Speedway as the forerunner for what exists in the IndyCar Series today. Even the new and swoopy Dallara DW12 chassis introduced last year exhibits those characteristics.

“Just the whole word ‘aerodynamics,’ Jim was really the guy who opened everybody’s eyes to it,” said current IndyCar team-owner Bobby Rahal, the 1986 Indy 500 champion. “Much of what we had today is based on that. There was always technology in racing, but it was less of a science and he brought a lot of science to it.”

Hall was a rarity as an engineer working with race cars. These days, team engineers are paid big bucks to find ways to make cars go faster. Engineers are a staple for major teams, not only in IndyCar racing, but also NASCAR and all major forms of auto racing.

Some of that thinking can be traced back to Hall, who was inducted into the Texas Motorsports Hall of Fame at The Speedway Club at TMS in 2005.

“The advent of people like Jim, and Mark Donohue, they made it more of a scientific exercise,” Rahal said. “Even after they stopped racing, Jim had his own race team, and he brought ground effects and the 2K to Indy. They introduced, and they opened the Pandora’s box, frankly. Ever since then the science has been crucial.”

While Hall was creating his legendary cars, the rules were less-stringent and there certainly was more room for innovation. But even in today’s world of racing under tight rules on engines, bodies, aerodynamics and tires, those in the IndyCar garage today believe Hall would still find a way to come up with something different.

“You know, you have restrictions, but somebody like him would figure something out,” Andretti said. “People like that have a tendency to excel no matter what.”

    The Chaparral 2K was really an Indy car adaptation/refinement of the concepts introduced by Colin Chapman’s Lotus 79 that Mario drove to the Formula One World Championship in 1978. Mr. Hall worked with ground effects as early as 1970 with the Can Am ‘sucker car’, the 2J, but with a second engine driving a set of fans supplying the negative air pressure.
