Ten Modern Car 'Inventions' You Thought Were New but Are Not

A visit to the General Motor Heritage Center outside Detroit serves as a reminder of the incredible ingenuity of very early carmakers.

After checking out everything luxury at the Detroit Auto Show last week, I spent some time at General Motor’s Heritage Center. The complex is about 30 miles from downtown Detroit and houses 15,000 linear feet of old paper archives (that’s a dozen Empire State Buildings stacked on top of each other); plus, the multiple warehouses there hold more than 400 cars made at one time or another over GM’s 100-year history.

The center is not open to the public, but you can make an appointment for a private visit. If you do go, I suspect you’ll both have a great time and be surprised by what you find. I know I was.

Seeing all that early technology in one place, I was struck by how much of it is not too different from what we expect in cars today—in fact, much of the stuff that many drivers think is new and freshly innovative was actually innovated decades ago. Take radar crash avoidance, for example—it's more than 50 years old. And alternative drive modes? We've definitely been there and done that.

I also loved seeing a lot of the old concepts at the Heritage Center that didn't make it today, having been cast aside because of budget cuts and increasingly stringent federal safety regulations. The V16 engine, for example, never came back to life because it drank massive amounts of fuel and would incur federal gas-guzzler penalties. I saw some crazy, oblong radar cones that aren’t aerodynamic enough to pass wind-resistance tests and huge tail fins that hid gas caps but which would require too much sheet metal to be economical. The cars listed below aren’t necessarily the very first to contain each technology, but they are notable examples of its use. 

High Beams

Notable Car: 1915 Cadillac Type 51. OK, these are a far cry from the automatic, road-smart, powerful LED headlamps we have today. But the idea behind them definitely started in 1915. That was the year Caddy introduced tilt-beam headlights, which were operated by a handle on the dash and were an early form of high beams. It proved a major advance in nighttime visibility and set the standard for others to follow.

Radar Detection for Crash Avoidance

Notable Car: 1959 Cadillac Cyclone Concept. Two dark domes on the front of the car housed detectors that would alert the driver in case another car got too close. (Another futuristic feature: The Cyclone also had tiny sliding doors—like on a minivan only much smaller.)

16-cylinder Engines

Notable Car: With the 1931 Cadillac V16, the marque became the first domestic car manufacturer to release a production model version of a V16 automobile. It came with a then-extremely high 165 horsepower engine, could hit 80 mph, and came in 10 body styles with nearly limitless color options. Consider it the Ferrari LaFerrari of its day. The MSRP was an expensive $6,500, roughly $100,000 in today’s dollars.

Push-Button Ignition

Notable Car: 1914 Ford Model T—the very first mass-produced car. Oops, did you stall it? No problem. Put on the emergency brake; place your left foot on the clutch to keep the car neutral (it will jump into second if you don’t); adjust the slim silver electric moderator lever on the steering wheel; and reach down below the bench to your left by the door to push the start button. Just like every luxury car today with their push-button starts—only way more complicated.

Alternate Drive Modes

Notable Cars: Cadillacs in 1933 came with a ride selector—essentially a lever—which allowed the driver to adjust the suspension damping/rigidity to improve the drive and handling on the fly. Tighter for smooth, fast roads. Looser for uneven terrain. There wasn’t quite a “sport” or “eco” mode, but this got the process started.

Automatic Rain Sensors

Notable Car: While a Le Sabre concept car first showed a novel rain sensor in 1951, the technology first appeared in production on the 1958 Cadillac Eldorado Biarritz convertible. The system worked by automatically closing the convertible top and raising the windows when sensors on the side of the car detected rain.

Removable Back Seats

Notable Car: 1903 Model A Runabout. This was the first Cadillac (and the one closely copied by Henry Ford). It had a single-cylinder engine and was known colloquially as the "Model A.” The front portion had a bench seat, and the back came with two removable seats—one positioned on each side.

Hidden Gas Caps

Notable Cars: Cadillac and many other smaller brands (Tucker) had a lot of models in the 1940s through the ’60s that obscured the fuel input—all the better for making wide clean lines along the sides of the body. An ingenious one made by GM was the 1955 Caddy Coupe DeVille, which hid it under one of the large tail fins. To access it, you pushed a little button and lifted up the top of the cap over the light at the top of the fin.

Electric Motors

Notable Cars: Many of them. In 1911, Woods Motor Vehicle Company introduced the first gasoline-electric hybrid car in Chicago. (Germany was producing electric cars as early as the 1880s.) More recently, in 1973, General Motors made the Urban Electric Car and promoted it for its electric battery and tiny two-seat design. GM hasn’t released too many stats about that car—it had a huge front swinging door and was just a concept, after all—but it was heavily discussed and photographed charging its battery at an important symposium on low-pollution power system development during that time.

Alternative Fuels

Notable Car: The 1956 Firebird II Experimental used kerosene (jet fuel, basically) to propel the four-seat “land-bound aircraft” to 200 horsepower. What’s more, the Firebird II was the first car to have four-wheel disc brakes, a fully independent suspension, and a guidance system that was supposed to use an electrical wire embedded into the road that would send signals to guide the car and help avoid accidents. Also: GM made something called the Electro-Van in 1966; it was the world's first hydrogen fuel cell-powered vehicle.
