From outer space to in our bloodstream, we’re surrounded by products and ideas that grew from research and development by General Motors. As the R&D group celebrates a century developing everything from paint to pioneering solar-powered and self-driving vehicles, GM’s scientists are focused on what’s next.
“The auto industry is fueled by innovation,” GM Chief Technical Officer Matt Tsien said. “Having an R&D group charged with looking ahead has served us well. To be a leader, we have to continue to scout out ahead.”

A century ago, that meant coming up with the first automotive lacquer paint process, an advance that slashed production time. Mid-20th century innovations included a mechanical heart pump that made open-heart surgery possible and centrifuges that made it possible to produce large quantities of vaccines. Today, R&D’s focus includes new battery chemistry so electric vehicles can go farther and cost less.

“Ten or 12 years ago, the Defense Advanced Research Projects Agency urban challenge” to create self-driving vehicles “looked like science fiction, but we saw a trend of high-def mapping, capable and affordable sensors, and the declining cost of computing and saw we could use them to begin solving automated driving.” Tsien said.
There are few greater sins a scientist can commit than taking credit for somebody else’s work, and GM R&D is commendably modest. When I asked about the Lunar Rover, engineered by GM and the only human-operated vehicle ever to move on the surface of another world, GM R&D practically blushed, responding that while it was involved, the Rover program “wasn’t led by R&D (it was a greater GM program).”
Here are a few of the advances GM R&D is willing to take credit for:
1929: The first room air conditioner. GM’s Frigidaire unit — yes, GM owned Frigidaire — developed an air conditioner small enough to use in vehicles and private homes.
1939-44: In addition to producing millions of vehicles, engines, weapons and more for WWII, GM R&D developments included super fuel for aircraft, variable pitch marine propellers for PT boats and landing craft, and military grades of steel.
1950s: Mechanical heart makes open heart surgery possible. Separately, GM’s research into high-speed bearings leads to creation of Centri-Filmer for sterilizing blood and vaccines. It was key to producing massive quantities of vaccines including the Salk polio vaccine.
1963: Positive Crankcase Ventilation valve is the first pollution control device. It’s adopted by the rest of auto industry to reduce hydrocarbon emissions.
1964: Electrovair electric Chevrolet Corvair uses a 450-volt, silver-zinc battery to reach speeds of 80 mph and ranges up to 80 miles.
1974: Catalytic converter. GM developed the catalytic converter to reduce emissions. GM says this led to “GM R&D becoming one of the first groups to predict the correlation between atmospheric pollution and the Earth’s surface temperature.”
All automakers adopted the catalytic converter, which GM made available for no charge. Catalytic converters remain vital emissions control devices today.
1987: First solar-powered race-winning vehicle. The Sunraycer won the 1,950-mile World Solar Challenge race in Australia by a wide margin.
2002: GM AUTOnomy concept. The “skateboard” chassis this drivable fuel-cell concept pioneered became the basis for most modern electric vehicles. The layout puts batteries in the vehicle’s floor, making them part of its basic structure, and had electric motors close to its wheels.
2005: Vehicle-to-vehicle communications. GM showed traffic efficiency and safety improve if vehicles share information about traffic, weather, etc. V2V technology is key to current programs for self-driving vehicles and smart infrastructure.
2010: Robonaut 2. GM develops a humanoid robot with sensors, vision and dexterity that allows it to work alongside humans in space. It’s currently on the International Space Station.
