First up is the Ford Model T, better known as the car that put America on wheels. The heart of this iconic vehicle was the T-4 engine, a marvel of its time that revolutionized the automotive world.

While 22 horsepower might not sound like much today, back then, it was quite impressive. More importantly, it shifted the entire country towards gasoline-powered internal combustion engines, moving away from the less reliable steam and electric predecessors. Its design featured innovations like removable cylinder heads and a cast crankcase, which made maintenance easier and helped standardize car production.

Ford's assembly line approach and the T-4 engine drastically reduced costs, making the Model T the first car many American families could afford. This marked an important shift in society, making car ownership and personal transportation a reality for more people.

Fast forward a bit to the Ford Flathead V8, which was a game-changer in its own right. Despite not being the first V8 to hit the mass market (that was Cadillac in 1914), the Flathead V8 made V8 power attainable for the average person. Launched in 1932, this engine was about more than just its 80 horsepower. It laid the foundation for motorheads to tweak and tune their cars for more speed, kickstarting the beginnings of the hot-rodding culture and even laying the groundwork for NASCAR.

In 1911, Fiat decided to push the limits of speed and engineering with a bold attempt to beat the land speed record. The vehicle the company created was nothing short of extraordinary, known affectionately as "The Beast of Turin," after its Italian birthplace.

The car was powered by a 28.4-liter, four-cylinder engine, a monster even by today's standards, and an adaptation from airplane technology. This engine produced a staggering 290-300 horsepower designed to beat Karl Benz's "Blitzen Benz" and its 126 MPH record.

The Fiat S76 was a powerful machine with a unique body to minimize air resistance. Even though it was designed to be as light as possible, the car still weighed in at a hefty 3,748 pounds. Its engineering focused on simplicity and efficiency, with features like solid axles, a chain drive, and brakes on the rear axle only. Speed was the goal here, rather than safety or comfort for the driver.

Fiat only ever produced two of these legendary cars. One ended up in the hands of a Russian Prince aiming to break the land speed record. With American driver Arthur Duray at the wheel, the car hit 132.27 MPH, but this record wasn't officially recognized since there wasn't a return run.

The Fiat S76 embodies a time when pushing the limits was the main goal of automotive design. It shows the evolution of car technology and serves as inspiration for pushing the boundaries in engineering and speed.

Introduced in 1951, the Chrysler HEMI V8 engine changed the game for American cars by making power steering more widely available with its hydraulically assisted "Hydra-guide" steering. This engine is a key part of the muscle car era, powering classics like the Dodge Charger and Challenger.

The history of the HEMI engine starts with its use in Chrysler's World War II aircraft engines before being adapted for cars in the 1950s, with names like "Firepower." The "HEMI" name comes from the engine's hemispherical combustion chambers, a design that allows for more volume above the piston, which leads to more efficient combustion. This design concept, dating back to 1901, became widely recognized for its effectiveness during WWII.

The first HEMIs were impressive, but the second-generation "Street Hemi" from 1964, with 426 cubic inches, really made a mark on muscle cars and motorsports. Today, HEMI engines vary from the 5.7-liter version in Ram 1500 trucks to the supercharged seven-liter Dodge Hellephant crate engine, showing the HEMI's ability to adapt and continue to perform.

With the automotive industry shifting to electric vehicles, the future of new HEMI engines looks uncertain, especially as models like the Dodge Charger and Challenger are being phased out. However, the HEMI engine's legacy is still recognized as a powerful and innovative force that shook up the industry in its heyday.

The rotary engine, also known as the Wankel engine, is a unique and innovative design that played an important role in defining Mazda's identity (and keeping it afloat) in the automotive industry. Developed by Felix Wankel in 1954, this engine broke the mold with its unique spinning rotor design, challenging the traditional piston engines that dominated the automotive world. This new design led to smoother operation and a more compact design. Introduced in the NSU Spider in 1964, it presented an innovative approach to engine technology.

Mazda took this innovation to heart, making the rotary engine the powerhouse behind their beloved RX-7 and RX-8 sports cars. This engine stood out for its high revving power, compact size, and the fun driving experience it offered, even though it used more fuel and had some initial reliability issues. By opting for the rotary engine, Mazda demonstrated a willingness to explore innovative avenues in engine design.

The rotary engine came with challenges such as high fuel consumption and initial issues with seals. However, these problems didn't overshadow its contributions. They were eventually solved, thanks to the work of Mazda engineers, led by Kenichi Yamamoto, with the introduction of a graphite-aluminium alloy seal and other creative engineering solutions.

Overcoming its initial difficulties, the Wankel rotary engine stresses Mazda's willingness to innovate and embrace entirely new concepts. Its contribution to automotive technology earns it a deserved spot on this list, showing how fresh ideas can drive progress in the industry.

In the mid-1970s, when the automotive industry was grappling with new EPA emissions standards, Honda was quietly revolutionizing the game.

The Toyota Prius, introduced in 1997 in Japan, revolutionized the auto industry by bringing hybrid technology to the mainstream. This marked a huge step forward for Toyota and cars in general, blending a gasoline engine with an electric motor to cut fuel use and emissions. Toyota had been working on this idea for five years, tackling challenges like making the battery last as long as the car itself.

The Toyota Hybrid System mixed a 1.5-liter engine with a high-torque electric motor, a generator, and a nickel-metal hydride battery. This setup became the blueprint for all Toyota hybrids that followed. This innovative engine launched on a new platform, paving the way for future models like the Corolla and RAV4. Despite its cutting-edge tech, the Prius kept a traditional, albeit controversial design, managing to look familiar while being revolutionary. Its sleek shape also made it slightly more fuel-efficient.

By May 2000, the Prius had gained popularity in both Japan and internationally, with more than 40,000 units in sales. This success confirmed the car's balance of environmental friendliness and practicality, most notably its 560-mile driving range. To address any concerns about its hybrid technology, Toyota introduced a five-year mechanical warranty in the UK, a European first.

By the end of its first generation in August 2003, Toyota had sold over 123,000 Priuses worldwide, confirming the market's interest in hybrid vehicles. The 2024 Prius model continues this trend, offering improved performance, better fuel efficiency, and an optional all-wheel-drive system.

In 2005, Bugatti rolled out the Veyron with a W-16 engine that truly shifted the gears in car engineering. This new engine combined four turbochargers with 1,500 horsepower to push cars faster than we ever thought possible, blending cutting-edge materials and engineering at the very top of what cars could achieve.

The Bugatti W-16 engine design was significant for being the most powerful in a production car at the time, producing 1,001 metric horsepower (987 American horsepower) and becoming the first road car to exceed 1,000 horsepower. Volkswagen, Bugatti's parent company, developed the W-16 by combining two V8 engines, using shared cylinder heads and a crankshaft.

The idea for the W-16 engine came from an unlikely place: a bullet train ride in Japan, which caught the imagination of Volkswagen's chairman, Ferdinand Piech, a longtime fan of 16-cylinder engines. To manage its massive power, the 8.0-liter engine with its four turbochargers needed an intricate cooling system with 10 radiators.

Bugatti announced in 2022 that the era of the W-16 engine was coming to an end, turning its focus to hybrids and electric engines. The W-16 engine, compact enough to fit in the same space as a V12 but lighter than a traditional V16, came from a 1997 idea by Piech.

The W-16 engine powered some of the fastest cars in the world, like the Veyron and Chiron, becoming a symbol of extreme automotive achievement with horsepower figures you'd more likely see on an aircraft than a street-legal car.

In 2008, Tesla Motors launched its first car called the Roadster, which introduced an electric powertrain that helped to change how people viewed electric vehicles (EVs). This innovation challenged the status quo and showed that electric cars could compete with the familiar gas-guzzling internal combustion engines the world had grown accustomed to.

Tesla Motors used an alternating-current induction motor, a technology developed by Nikola Tesla in the 19th century. AC induction was efficient, simple, and reliable, allowing the motor to work well at different speeds. Initially, the Roadster had a two-speed transmission to help with acceleration and speed, but due to production issues, Tesla switched to a single-speed transmission that was more reliable.

The Roadster also had a power electronics module that managed the car's power which allowed for fast acceleration and smooth driving. The car's battery pack was made of 6,831 lithium-ion cells and a driving range of over 200 miles on a single charge. This was a substantial improvement over the older nickel-metal hydride batteries found in earlier hybrid cars. Tesla designed the Roadster with a lightweight aluminum frame and carbon-composite body panels to make it more efficient and extend its range.

The Tesla Electric Powertrain showed that EVs could have advanced technology and excellent performance, proving that electric cars could be as good as or better than some of the fastest sports cars. This was a big step in making electric vehicles more popular in the car market.
