The automotive industry designs, develops, manufactures, markets, and sells motor vehicles, and is one of the Earth's most important economic sectors by revenue.

The term automotive industry usually does not include industries dedicated to automobiles after delivery to the customer, such as repair shops and motor fuel filling stations.

The first practical automobile with a petrol engine was built by Karl Benz in 1885 in Mannheim, Germany. Benz was granted a patent for his automobile on 29 January 1886, and began the first production of automobiles in 1888, after Bertha Benz, his wife, had proved with the first long-distance trip in August 1888 (104 km (65 mi) from Mannheim to Pforzheim and back) that the horseless coach was absolutely suitable for daily use. Since 2008 a Bertha Benz Memorial Route commemorates this event.

Soon after, in 1889, Gottlieb Daimler and Wilhelm Maybach in Stuttgart designed a vehicle from scratch to be an automobile, rather than a horse-drawn carriage fitted with an engine. They also are usually credited as inventors of the first motorcycle, the Daimler Reitwagen, in 1885, but Italy's Enrico Bernardi, of the University of Padua, in 1882, patented a 0.024 horsepower (17.9 W) 122 cc (7.4 cu in) one-cylinder petrol motor, fitting it into his son's tricycle, making it at least a candidate for the first automobile, and first motorcycle. Bernardi enlarged the tricycle in 1892 to carry two adults.

Preston Thomas Tucker (September 21, 1903 – December 26, 1956) was an American automobile designer and entrepreneur.

He is most remembered for his 1948 Tucker Sedan (known as the "Tucker '48" and initially nicknamed the "Tucker Torpedo"), an automobile which introduced many features that have since become widely used in modern cars. Production of the Tucker '48 was shut down amidst scandal and controversial accusations of stock fraud on March 3, 1949. The 1988 movie, Tucker: The Man and His Dream is based on Tucker's spirit and the saga surrounding the car's production.

Preston Tucker was born on September 21, 1903, on a peppermint farm near Capac, Michigan. He grew up outside Detroit in the suburb of Lincoln Park, Michigan. Tucker was raised by his mother, a teacher, after his father died of appendicitis when Preston was 2 years old. First learning to drive at age 11, Tucker was obsessed with automobiles from an early age. At age 16, Preston Tucker began purchasing late model automobiles, repairing/refurbishing them and selling the cars for a profit. He attended the Cass Technical High School in Detroit, but he quit school and landed a job as an office boy for the Cadillac Motor Company, where he used rollerskates to make his rounds more efficiently. In 1922, young Tucker joined the Lincoln Park, Michigan police department (against the pleas of his mother), his interest stirred by his desire to drive and ride the fast, high-performance police cars and motorcycles. His mother had him removed from the force, pointing out to department officials that at age nineteen, he was below the department's minimum required age.
