when did air conditioning get put in cars
Automobile air conditioning In 1939, Packard became the first automobile manufacturer to offer an air conditioning unit in its cars.[2] These were manufactured by Bishop and Babcock Co, of Cleveland, Ohio. The "Bishop and Babcock Weather Conditioner" also incorporated a heater. Cars ordered with the new "Weather Conditioner" were shipped from Packard's East Grand Boulevard facility to the B&B factory where the conversion was performed. Once complete, the car was shipped to a local dealer where the customer would take delivery.
Airbag The first commercial designs were introduced in passenger automobiles during the 1970s with limited success and actually caused some fatalities.[2] Broad commercial adoption of airbags occurred in many markets during the late 1980s and early 1990s with a driver airbag, and a front passenger airbag as well on some cars; and many modern vehicles now include six or more units.[3]
Automobile air conditioning Air-conditioning for automobiles came into wide use from the late twentieth century. Although air conditioners use significant power; the drag of a car with closed windows is less than if the windows are open to cool the occupants. There has been much debate on the effect of air conditioning on the fuel efficiency of a vehicle. Factors such as wind resistance, aerodynamics and engine power and weight must be considered, to find the true difference between using the air conditioning system and not using it, when estimating the actual fuel mileage. Other factors can affect the engine, and an overall engine heat increase can affect the cooling system of the vehicle.
Airbag In the early 1970s, Ford and General Motors began offering cars equipped with airbags, initially in government fleet purchased Chevrolet automobiles. GM's Oldsmobile Toronado was the first domestic vehicle to include a passenger airbag.[when?][citation needed] The automaker discontinued the option for its 1977 model year, citing lack of consumer interest. Ford and GM then spent years lobbying against air-bag requirements, claiming that the devices were unfeasible and inappropriate. Chrysler made a driver-side airbag standard on 1988â€“1989 models, but it was not until the early 1990s that airbags became widespread in American cars.[24]
