1807 - Francois Isaac de Rivaz of Switzerland invented an "internal combustion engine" that used a mixture of hydrogen and oxygen for fuel. Rivaz designed a car for his engine - the first internal combustion powered automobile.
1824 - English engineer, Samuel Brown adapted an old Newcomen steam engine to burn gas, and he used it to briefly power a vehicle up Shooter's Hill in London.
1864 - Austrian engineer, Siegfried Marcus*, built a one-cylinder engine with a crude carburetor, and attached his engine to a cart for a rocky 500-foot drive. Several years later, Marcus designed a vehicle that briefly ran at 10 mph that a few historians have considered as the forerunner of the modern automobile by being the world's first gasoline-powered vehicle
1873 - George Brayton, an American engineer, developed an unsuccessful two-stroke kerosene engine (it used two external pumping cylinders). However, it was considered the first safe and practical oil engine.
1866 - German engineers, Eugen Langen and Nikolaus August Otto improved on Lenoir's and de Rochas' designs and invented a more efficient gas engine.
1876 - Nikolaus August Otto invented and later patented a successful four-stroke engine, known as the "Otto cycle".
1876 - The first successful two-stroke engine was invented by Sir Dougald Clerk.
1883 - French engineer, Edouard Delamare-Debouteville, built a single-cylinder four-stroke engine that ran on stove gas. It is not certain if he did indeed build a car, however, Delamare-Debouteville's designs were very advanced for the time - ahead of both Daimler and Benz in some ways at least on paper.
1885 - Gottlieb Daimler invented what is often recognized as the prototype of the modern gas engine - with a vertical cylinder, and with gasoline injected through a carburetor (patented in 1887). Daimler first built a two-wheeled vehicle the "Reitwagen" (Riding Carriage) with this engine and a year later built the world's first four-wheeled motor vehicle.
1886 - On January 29, Karl Benz received the first patent (DRP No. 37435) for a gas-fueled car.
1889 - Daimler built an improved four-stroke engine with mushroom-shaped valves and two V-slant cylinders.
1890 - Wilhelm Maybach built the first four-cylinder, four-stroke engine.

Good thread. Since it's titled who invented the first car instead of who invented the first engine, I'd have to say Karl Benz is the answer. He is credited with the first successful roadgoing car. At least that's what I learned the last time I did a history check.
Here's a link of Karl info.
