Introduction
The point of divergence from OTL is late 1973, and this timeline concerns the United States automotive market.
For the 1974 model year, General Motors introduced the Air Cushion Restraint System (ACRS) as an option on certain Buick, Oldsmobile, and Cadillac models.
ACRS was the first airbag system put into production vehicles that normal consumers could buy, and featured dual front airbags designed to protect all three front passengers (most cars that ACRS was available on had front bench seats). It cost about $200 ($1,343 in today's dollars) and was marketed as both a safety feature and a convenience feature; the federal government had mandated that all 1974-model cars have an interlock system that prevented starting the car unless the front seat belts were fastened, unless the car had a "passive restraint" (a restraint designed to provide crash protection without action from the occupants, such as airbags or automatic seat belts). The ACRS was the only passive restraint offered at the time IOTL; all other vehicles had the much-hated seat belt interlock system. In fact, ACRS-equipped cars had only front lap belts (the airbag was intended to replace the shoulder belt; the lap belts were primarily for protection in non-frontal crashes)
IOTL, ACRS was commercially unsuccessful. Only 10,000 cars were sold with it in the three model years it was available (1974-1976), and when GM redesigned its full size car platform in 1977, there was no provision for airbags.
Here is a 10-minute promotional video from 1974 explaining the ACRS.
ITTL, however, ACRS is commercially successful from Day 1, being ordered by a majority of buyers (around 60% to start out), and GM has adequate production capacity and markets the system much more heavily than they did IOTL.
1974 Model Year
The models equipped with the ACRS this year will be the same as they are IOTL; other manufacturers haven't yet had time to introduce their own airbag-equipped models ITTL. That means that the Buick Riviera, Electra, and LeSabre, Oldsmobile Toronado, Delta 88, and 98, and Cadillacs. Convertibles and limousines did not have ACRS availability.
For the 1974 model year, 20,129 Rivieras, 99,414 Electras, 94,126 non-convertible LeSabres, 117,877 non-convertible Delta 88s, 70,556 98's, 27,582 Toronados, and 242,330 Cadillacs (of which a few thousand were convertibles/limousines) were produced, for a total of 672,014 (minus a few thousand) eligible vehicles.
About 8.8 million cars were sold in total in the USA in 1974. ITTL, 304,594 ACRS-equipped vehicles are sold for the 1974 model year, despite it only being available for 9 months of the model year (Dec. 1973 - Sept. 1974). This means that over 3% of 1974-model vehicles come with ACRS, a great start. On April 23, 1974, GM announces that the 1975 Chevrolet Caprice, Impala, and Bel Air, which are on the same platform as the existing models with ACRS, will have the system as a $175 option. They also announce that all 1975 Cadillacs will have ACRS as standard equipment.
Other manufacturers take note.
Ford - Ford equipped a few Mercury Montereys with a passenger airbag for insurance fleets in 1972, so they have some experience with airbags.
April 26th - They announce optional dual airbags on full-size Fords for 1975 models, due to go on sale in October 1974. The Ford LTD, Custom, Mercury Monterey, Marquis will get optional dual airbags; they will be standard on the facelifted 1975 Lincoln Continental. Like GM, they only equip the airbag-equipped cars with lap belts.
Volvo
May 14th - Volvo announces that its new 200-Series, due to go on sale as a 1975 model, will have a driver airbag standard, along with 3-point seat belts. Volvo defends their decision, stating that their 3-point seat belt system provides just as much protection for passengers as a lap belt and airbag would. They also state that their internal research has shown that passenger airbags can be dangerous to children, and that they're developing an improved passenger airbag system that will be available in a couple years.
Although only Ford and Volvo announce airbag availability on specific models this year, other manufacturers - including Chrysler, AMC, and even Datsun and Toyota - state that they are researching airbag systems and will include them on cars in the near future.
Late in the model year, IIHS does a series of 35-mph front crash tests comparing a GM ACRS-equipped Buick Electra to its competitors, the Mercury Marquis, Chrysler Newport, AMC Ambassador, and a non-ACRS equipped Electra. Seat belts are buckled for all occupants. The test results are released on July 16, 1974, and the ACRS-equipped Buick passes with flying colors for both occupants; no serious injuries would be expected. The other four fail the test, with severe injuries expected to their occupants. This series of crash tests only further increases the demand for airbag systems.
By August 31, 1974, the close of the 1974 model year, over 250 lives have been saved by the ACRS system. One of these cases made headline national news on March 25, 1974, and a few others have also gotten widespread reporting; most have been been on the local news near where the crashes occurred.

1971-1978 Oldsmobile Toronado
The 1971-1978 Oldsmobile Toronado started with a full redesign and new features were added each year. This car featured a grilleless design that pushed the grill openings to the far edges of the bumper. Learn more about the Toronados of this period.

1974 Cadillac Production Numbers/Specifications
An oil embargo against the U.S. resulted in gas shortages, which curtailed sales and production of big cars in 1974, which included Cadillac.
