Cadillac: A History of Innovations Since 1902
For Release -
GM, January 6, 2002
Detroit - Cadillac's reputation for design and technological innovation goes back a century to when Henry M. Leland built the first Cadillac automobile. Cadillac's pioneering spirit has enabled it to rapidly advance noteworthy technological discoveries from the laboratory to the assembly line, enhancing the performance and prestige of Cadillac vehicles. "Innovation is rooted in Cadillac's heritage," said Mark LaNeve, Cadillac general manager. "Breakthrough design and technology made Cadillac the standard of the world. As we begin our second century, we are applying the same type of creativity in order to deliver innovations that will once again win over our customers."
Among Cadillac's many innovations, it was the first automaker to use a self-starter, the first with an independent front-wheel suspension and first with the syncromesh transmission. Cadillac offered the first mass-produced V8 engine and the first mass-produced vehicle stability system. Other major innovations include the modern overhead valve V8 engine, America's first transverse-V8/front-wheel-drive automobile, the 32-valve Northstar V8 and the evolution of the Northstar System with its integration of performance and control systems. Cadillac's tradition of pioneering technological advancements with real customer benefits continues today, with features such as Night Vision, DVD-based navigation, XM Satellite Radio and next-generation MagneRide active suspension damping - known as Magnetic Ride Control. Following is a chronology of significant Cadillac innovations, listed by model year.
1903 The first Cadillac automobile was completed on October 17, 1902. Powered by a 10-horsepower, single-cylinder engine and costing $750, the car sold out at its introduction during the 1903 New York Automobile Show. The first Cadillac engine used mechanically actuated overhead valves and a square bore-stroke ratio. Steering was by a rack-and-pinion gear. An early innovation was the use of special split-core fasteners, which locked a nut on its thread with no need for lock washers.
1907 President and general manager of Cadillac, Henry M. Leland, imported the first set of Johansson gauges (Jo-blocks) from Sweden to facilitate the manufacture of precise automobile components with standardized dimensions.
1908 Cadillac became the first American automaker to win Great Britain's prestigious Dewar Trophy, given to the manufacturer making the year's most significant automotive advancement. This happened after a demonstration during which three randomly selected Cadillacs were disassembled, their parts scrambled, and reassembled using only simple hand tools. An immediate 500-mile demonstration run proved the ready interchangeability of each car's 721 standardized component parts. Soon after, Cadillac adopted the slogan, "Standard of the World."
1910 Cadillac introduced closed bodywork - called a limousine - as a standard catalog offering. Also in 1910, a Delco coil and breaker-point ignition system was first offered as a major improvement in reliability over magneto ignition.
1912 Cadillac was the first company to adopt a sophisticated Delco electrical system to handle self-starting, ignition and lighting functions. The Royal Automobile Club of Great Britain awarded Cadillac the Dewar Trophy for the second time, making it the first car company to win the award twice.
1915 Cadillac unveiled the first mass-produced V8 engine. One significant innovation with the 70-horsepower, 314-cubic-inch (5.1 liter) L-head design was the thermostatic control of cooling-water circulation. The engine, multi-plate clutch and gearbox were combined in one bolted-together assembly. The United States War Department purchased over 2,000 standard Cadillac V8 models for use in Europe during World War I.
1922 Cadillac began controlling the engine's fuel mixture thermostatically. Except for choke operation during starting, the driver was relieved of all carburetor adjustments.
1924 A fundamental advancement in the design of V8 automobile engines was the incorporation of a fully counter-weighted two-plane crankshaft. All primary and secondary forces were balanced to vastly improve the smoothness of V8s in Cadillac automobiles. The introduction of lacquer paint reduced manufacturing time and improved the finish of car bodies.
1927 Cadillac introduced a smaller, more maneuverable, sporty "companion car" - the LaSalle. It was the first U.S. car to be designed by a stylist, Harley Earl.
1929 Security Plate safety glass, double-acting Delco shock absorbers, and chrome-plated trim items were introduced for all models. Cadillac eliminated gear clash during shifting by the introduction of a new "Synchro-Mesh Silent-Shift" transmission. Bronze-on-steel cones matched speeds during shifting to facilitate the smooth meshing of gears.
1930 Cadillac introduced the world's first V16 engine for passenger-car use. This engine featured overhead valves with hydraulic lash adjusters, twin carburetors, dual exhaust, and a beautifully finished exterior design. It delivered 160 horsepower from 452 cubic inches (7.4 liter). A V12 derivative introduced later in the same model year produced 135 horsepower from 368 cubic inches (6.0 liter).
1938 To clear the floor and facilitate comfortable three-abreast seating in the front seat, Cadillac relocated the gear shift to the steering column. Cadillac also introduced an all new 16-cylinder design for a limited number of luxury models. This 431-cubic-inch (7.1 liter) L-head engine used twin carburetors, water pumps and distributors to generate 185 horsepower. Cadillac offered the first sunroofs available in America.
1941 Cadillac introduced a fully automatic transmission consisting of a fluid coupling, four forward speeds, and a hydraulic "brain" one-year after Oldsmobile pioneered this innovation in its 1940 models.
1948 The industry's first curved windshields were introduced by Cadillac and other GM models. This also marked the first use of the Harley Earl-designed tail fin.
1949 Cadillac initiated the '50s-era horsepower war with the introduction of a modern overhead-valve V8 rated at 160 horsepower. The 331-cubic-inch (5.4 liter) engine featured high compression, a short stroke and lightweight construction. The first Cadillac Coupe de Ville introduced the two-door hardtop body style.
1954 Three safety innovations by Cadillac were an "autronic eye" which automatically dimmed the headlamps, a one-touch system for washing and wiping the windshield, and a padded instrument panel cover.
1957 Cadillac's ultra-luxurious Eldorado Brougham introduced the quad headlamp system, a brushed stainless-steel roof panel, a power seat with memory, automatic door locks, "wide oval" (low profile) tires, forged-aluminum wheels and air suspension. One feature common with mainstream Cadillac models was a foot-operated parking brake that automatically released when the transmission was shifted into gear.
1959 Low-pressure freon-filled shock absorbers improved Cadillac's ride quality.
1960 Self-adjusting brakes were adopted.
1964 Comfort control was introduced by Cadillac to provide customers with the auto industry's first thermostatically regulated heating, ventilating and air conditioning system. A Twilight Sentinel automatically turned headlamps on at dusk and off at sunrise. Front seat belts became standard Cadillac equipment.
1965 The introduction of Delco Superlift rear shock absorbers provided automatic load-leveling capability. A tilt and telescoping steering wheel adjustment was also added to Cadillac models.
1966 Variable-ratio power steering permitted quick parking maneuvers with a slower ratio for more stable highway control. Electric seat warmers and a stereo radio were added as optional equipment.
1969 With the U.S. industry's first closed cooling system, engine coolant lost as a result of momentary overheating was automatically captured and returned to the radiator.
1971 Computerized anti-lock rear brakes were introduced as optional equipment.
1974 Along with Buick and Oldsmobile, Cadillac pioneered the use of an air cushion restraint (airbag) system to protect the driver in the event of a frontal collision.
1975 Cadillac was the first U.S. manufacturer to use electronic fuel injection.
1978 Digital electronics were programmed by Cadillac to operate a Seville trip computer. Two years later, integrated circuits took command of fuel injection, ignition and vehicle diagnostics.
1985 Cadillac introduced America's first transverse-V8, front-wheel-drive automobile. Another advanced feature in the new DeVille line was a viscous-damped, torque-converter clutch.
1987 A multiplex wiring arrangement was introduced on the Cadillac Allanté to control exterior lighting.
1990 Allanté became the first front-wheel-drive vehicle with electronic traction control. The system controlled wheelspin by adjusting application of the individual front brakes, then by reducing engine power by cutting off fuel to individual cylinders.
1992 The Northstar engine was introduced as the first step in what eventually became the Northstar System. The 4.6-liter, 32-valve V8 was first installed in the Allanté and became available in other front-wheel-drive Cadillacs a year later.
