When the field lines up on the Indianapolis Motor Speedway track this weekend, they’ll begin with a pace lap behind a 2014 Chevrolet Corvette Stingray driven by San Francisco 49ers coach Jim Harbaugh.
Although Harbaugh might be more used to a gridiron than starting grid, he should feel at home behind the wheel of the newly updated ‘Vette that owes much of its advancements to the General Motors racing program, from the way its 450-horsepower V-8 works to the carbon fiber panels used to reduce the sports car’s weight and lower its center of gravity.
“Motorsports play a key role for us in improving our street cars and powertrains,” explained Jim Campbell, head of GM’s well-funded motorsports program.
Most auto manufacturers participate in racing programs, from short track sprints to endurance races like the legendary 24 Hours of Le Mans. They’re even backing new “green” racing events, including one loosely affiliated with Formula One, that proponents say could yield significant improvements in battery-car technology.
The auto industry has been actively involved in racing since the earliest days of the automobile. Henry Ford got backers to finance his company after winning a race in one of his prototypes. Chevrolet, owned by General Motors, was founded by racer Louis Chevrolet.
Campbell, a former Chevy general manager, said that since those early days, GM has counted on racing to “improve the breed.”
The Corvette is a great example. Its 6.2-liter V-8 uses direct injection to achieve the seemingly contradictory needs of increasing power while also boosting fuel economy. GM first tried direct injection technology on the track. The same is true for the super-strong and ultra-light carbon fiber panels used for the Stingray’s roof and hood.
“It’s all about technology transfer,” Campbell said. He added another benefit: “It’s also a great place to train our engineers in an environment that’s very demanding and very fast-paced.”
An automaker might take years to find ways to boost the performance of a new engine sold through its showrooms. But it may have just days to achieve similar results if it hopes to be competitive on the track.
There’s another advantage to a successful program. The old industry adage is “Win on Sunday, Sell on Monday.” But industry marketers are trying to improve on that motto, using social media and other efforts to draw race fans into showrooms every day of the week.
Mazda is betting that its new endurance racing program will focus attention on its new SkyActiv-D diesel engine – and reveal ways to improve the technology that will be introduced in a street version of the new Mazda6 for 2014.
While it might seem obvious that high-performance vehicles like the Corvette might benefit from racing’s technology transfer, motorsports can improve even less sexy vehicles like the Chevrolet Equinox crossover, the Ford Fusion sedan and Toyota Avalon.
Industry engineers say that many of the latest developments in basic powertrain technology – especially with higher-performance turbochargers – can be considered “track tested.”
Formula One’s intense focus on aerodynamics has helped the industry learn a lot about cheating the wind to radically improve fuel economy.
Many of the technologies that have made racing safer over the decades have been transferred to street cars, said Richard Cregan, former manager of Toyota’s Formula One program and now the head of the Yas Marina F1 circuit in Dubai.
Hoping to learn even more about aero styling, Nissan last year sponsored the radical DeltaWing, an experimental, jet-shaped racer that ran at Le Mans.
Nissan recently announced plans to ramp up production of its special, high-performance Nissan Motorsport International Limited models, including a version of its GT-R sports car. “It’s too early to share any details yet, but fans can be certain we’ll be applying all of our motorsport expertise to creating a GT-R NISMO worthy of the name,” said NISMO President Shoichi Miyatani.
There are critics who question the benefits of racing, fearing that it simply focuses on high-performance, fossil fuel-powered vehicles. But racing could soon help develop better “green machines.”
The Formula E series is planning to debut next year with a field of 10 cars in 10 different races, all based in urban centers such as London.
“The fact that we will only race in city centers highlights the main message of our Championship: The electric car as a solution for mobility in cities of the future,” explained Alejandro Agag, CEO of Formula E Holdings, adding that the demands of the track could help yield significant improvements in battery power-train technology.
“I think there’s life beyond NASCAR and Formula One,” said Herb Fishel, who retired a few years ago as GM’s motorsports chief and is now involved in green motorsports efforts. “It will come as we see new forms of racing evolve.”
