   Hemi

The 1953 Red Ram engine was the first Dodge motor to use hemispherical (Hemi) combustion chambers. This dome-like structure produces more power than its "flat" cylinder cousins. Chrysler's first Hemi motor was the FirePower engine, developed a few years earlier, but the Red Ram was the first for the Dodge brand.

The original Ford Boss 302 — named for its cubic-inch displacement, which also works out to 4.9 liters — is a high-performance small block engine that was on the market from 1969 through 1970. It was used in the Boss 302 Mustangs and Cougar Eliminators.

Used in GM trucks beginning in the 1985 model year, the Vortec engine was named for its "vortex technology" that atomizes the air/fuel mix in the combustion chamber. It's come in many shapes and sizes, ranging from the inline-four Vortec 2200 to the Big Block Vortec 8100 V8.

Used without a lot of modification from 1936 through 2006, the Volkswagen air-cooled engine has moved a lot of people to a lot of different places all around the world. The engine has four horizontally opposed cylinders and has been sized from 1.0 liter to 1.6 liters throughout most of its production run. The engine pictured here is a 1953 1.2-liter engine, which was used from 1950 to 1991.

   Wankel

Between 1963 and 2012, Mazda used a version of the Wankel rotary combustion engine. Developed by German engineer Felix Wankel, this motor allows the parts to rotate in one direction, which is different from the motion of the standard reciprocating piston engine, where the pistons change directions. The Wankel motor is known for high power-to-weight ratio, but also for its poor fuel efficiency. The 2012 Mazda RX-8 was the last car to be powered by the Wankel engine.

The engine in the DeLorean Motor Company's one and only produced vehicle was a 2.85-liter Peugeot-Renault-Volvo (PRV) V6 that was rated to generate 130 horsepower. Unfortunately, this powerplant was underpowered for the expectations people had for the vehicle. This is one of the reasons the DMC DeLorean didn't succeed. The car, of course, became famous later for its star turn in the "Back to the Future" trilogy of films.

The flat-six engine — where the cylinders are horizontally opposed, with three on either side of the central crankshaft — has been used in a number of vehicles. Still, it's most famous for its inclusion in the famous Porsche 911, where it's been used exclusively since 1963.

Built between 1949 and 1990, the Oldsmobile V8 "Rocket" has powered a great many automobiles over the years. The engine has come in many different sizes, ranging from a 5.0-liter small block version to an incredible 7.5-liter big block bully. There was also a turbocharged version of this engine, which was rightfully called the Turbo-Rocket.

Since the Volkswagen Group owns many different automobile manufacturers, you'll find the term "TDI" used not only by Volkswagen but also by Audi, SEAT and Skoda. Whatever the company, the letters are the company's acronym for "Turbocharged Direct Injection," first used in the 1989 Audi 100 TDI sedan.

He was best known for his collaborations with Ford, particularly his work with the Mustang, but there were periods when auto design legend Carroll Shelby worked with other companies, such as Dodge. In 1987, he worked with the automaker to develop the Shelby Lancer, which offered a 2.2-liter intercooled turbocharged inline-four that could produce 175 horsepower. Only 800 were ever made.

The Corvair Monza Spyder Turbo Six from Chevrolet was released in 1962. The Corvair was a rear-engined car, which was (and still is) rare for an American-made vehicle. The Corvair came under scrutiny in Ralph Nader's ground-breaking consumer advocate book "Unsafe at Any Speed," but the modern age of turbocharged engines started here.

The Porsche 959, released in 1986, used a 2.8-liter twin-supercharged flat-six engine to make it the world's fastest production car when it first hit the streets. The engine could power the car to 197 miles per hour, with some high(er)-performance variants able to reach 211 miles per hour.

The Polara first hit the streets in 1959 as Dodge's top-of-the-line full-size vehicle, but it was eventually changed to a mid-size car to compete with Ford's Galaxie 500 and Chevrolet's Impala. Made in four generations, the last iteration of the vehicle had one inline-six and five V8 engine options, the largest of which was a 7.2-liter monster.

The Chevrolet Camaro first hit the streets in 1967 as the automaker's response to the Ford Mustang. The car soon blazed its own trail in the automotive world. In 1985, Chevy put out an edition named after the International Race of Champions (IROC) as a performance variant. The Camaro IROC engine in this photo is a 1987 5.7-liter V8.

The Ford FE (Ford-Edsel) engine was made for vehicles in the North American market from 1958 through 1976, replacing the Y-block engine design that was becoming too small for the power requirements of modern vehicles. The engine shown here is a 405.7-cubic-inch (or 6.6-liter) TriPower from a Ford Galaxie.

Ford’s 427 CID SOHC V8 engine, nicknamed the "Cammer," was built in response to Chrysler's 426 Hemi, which had allowed Richard Petty to dominate the 1964 Daytona 500. Ford developed the Cammer in just three months. NASCAR didn't allow the overhead cam engine to be raced on the track, however, and the engine was never released for showroom models either, making it a bit of a legend in the gearhead community.

The Zetec engine, which debuted in 1991, was originally called the Zeta engine, but the company was forced to change it because the Italian automobile manufacturer Lancia owned the trademark on that name.

A kei car, or city car, is a very small vehicle, as designated by the Japanese government, made for urban errands. This particular engine powered a 1969 Honda N360, which was a two-passenger automobile. It wouldn't be great for highway driving, but it was fine for the stop-and-go traffic of a city.

Chevy's small block engines are a family of V8 motors produced by the company from 1954 through 2003. They used the same basic engine block and ran from 4.3-liter to 6.6-liter sizes — big block engines took over from there. The engine in this particular picture is a 350-cubic-inch (5.7-liter) small block from a 1969 Buick Skylark GS 350.
