-
It was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot. It was used by the French Army to haul artillery at a whopping speed of 2 1/2 mph on only three wheels. The vehicle had to stop every ten to fifteen minutes to build up steam power.

Making it easier to stop safely. They came out in 1920's but by the end of the decade almost all cars had four wheel brakes.

A coil spring is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. Came first in the front, later for the back wheels, too.

Made driving much easier and safer.

Automatic transmissions had already been through a number of iterations, as the demand for them rose, however, and the ways they worked became simpler and more powerful, the three-speed truly automatic transmission comes into its own.

After many tries, by 1984 manufacturers are figuring out cost-effective and safe ways to deploy airbags. They start to become standard features for the first time.
-
The Lincoln becomes the first American car to offer an antilock braking system (ABS), which is made by Teves of Germany. ABS uses computerized sensing of wheel movement and hydraulic pressure to each wheel to adjust pressure so that the wheels continue to move somewhat rather than "locking up" during emergency braking.

Changing the fuel that cars use in the first place could be one of the most profound steps in automotive evolution. A hybrid is a vehicle if it utilizes more than one form of energy. A hybrid will have a traditional internal-combustion engine and a fuel tank, as well as one or more electric motors and a battery pack.
