To most, a car engine is just a collection of metal pieces that live under the hood. Car aficionados know, however, that the story goes a lot deeper than that. The engine is arguably what makes the car and its driving experience unique, as well as what can launch a car into legendary status. From the beginning of the automotive industry to the present, many engines have earned respect due to their ability to last, their ingenuity, performance, or cultural impact.

The finest engines leave behind a legacy far after the cars that contain them. Engines become a legendary part of automotive history passed down from one enthusiast to another. Some earned it on the race track, others by simply refusing to fail, while still more broke boundaries on performance levels previously unimaginable. They inspired a generation of builders and dreamers and, in the process, helped define certain eras of automotive styling.

The list of great engines can likely be a lifelong debate for many car enthusiasts, but certain engine combinations have, throughout time, gained a reputation far across the board among car people. From some naturally aspirated powerhouses that scream and whir, to forced-induction marvels that can gain vast amounts of power, here is a collection of ten of the greatest engines in history.

1. Toyota 2JZ-GTE

Widely regarded as one of the greatest engines of all time, the 3.0L twin turbo inline-six known as the Toyota 2JZ-GTE became an icon within tuner culture and automotive performance for its extreme strength and power output potential. Powering a legend in the automotive world (the Toyota Supra MK4), the 2JZ-GTE received worldwide fame and recognition and still has one of the most respected names to ever come out of the automotive industry.

Why the 2JZ-GTE Became Legendary:

• Strong iron block construction
• Twin-turbocharged inline-six design
• Exceptional tuning potential
• Proven long-term durability
• Massive horsepower capability

It’s primarily due to its extreme robustness and durable construction. It has a strong cast iron block and forged internals; as well as a design that enables it to cope with far more power than it was originally designed for. Factory performance was quite excellent, but it was its role as an enthusiast-tunable engine that cemented its legendary status. Tuners realized that with relatively few modifications the engine was more than capable of putting down huge amounts of power. 

With thousands of cars and their 2JZ-GTE’s producing over 1,000hp reliably, it is hard to find an production car engine that is more capable and more durable. The robustness it offered transformed the already superb 2JZ-GTE into what is considered one of the true automotive legends to this day.

2. Honda F20C

The Honda F20C is a prime example that a fantastic engine has to do with more than just size. The naturally aspirated 2.0 liter inline four is an absolute masterpiece at spinning and at 9,000 RPM is one of the highest revving production cars ever. Honda once again proved its engineering capabilities and gave it an outstanding unique characteristic.

What Makes the F20C Special:

• Extremely high 9,000 RPM redline
• Naturally aspirated engine design
• Exceptional power-per-liter output
• Sharp throttle response characteristics
• Iconic Honda engineering excellence

Found in the iconic Honda S2000, the F20C really showcased Honda engineering at its finest. It also boasts one of the highest power to liter ratio ever achieved in a normally aspirated production engine when it first arrived. The focus for this engine was about responsiveness and balance between the driver and the car. The nature of this engine rewarded you for using the engine to its full potential at higher revs and provided a satisfying experience behind the wheel. 

The F20C performance was unleashed toward redline and gave an exciting engine note with power to back it up each time you visited the higher range of the revs. This made the Honda S2000 an exciting vehicle to drive, even after it ceased production, and is an engine that is highly appreciated by petrol heads across the world today.

3. Chevrolet Small Block V8

One of the most important V8s in automobile history, the Small Block V8, made by Chevrolet, came on the scene in 1955 and since then has become the centerpiece of performance automobiles, all around the country. It was influential in the muscle cars, the sports cars, the custom built hot rods of years past and still stands the test of time among automobile enthusiasts and manufacturers alike.

Reasons Behind Its Lasting Legacy:

• Simple and durable design
• Strong aftermarket support
• Excellent performance potential
• Widely used across platforms
• Iconic American automotive heritage

One of the main reasons for its incredible success was that it combined simplicity and versatility. The engine could be worked on, customized and tuned very easily while still remaining reliably. This ability allowed it to be installed into such a wide variety of applications over a huge length of time. This has made it the most commonly used aftermarket engine of all time, valued by modifiers for its basic design and tuning potential. This has led to so many performance builds being developed based around the “small block” V8 that many consider this to be one of the best engines ever built for aftermarket performance tuning, and it’s easy to see why. Not only were the engineering aspects of the small block V8 excellent, it also became something of an icon for the american muscle car. Builders would flock to this engine because it was cheap to buy and there were so many aftermarket performance parts available for it.

4. Porsche Mezger Flat-Six

The Porsche Mezger flat six is undoubtedly an engine that holds a unique and revered status in the world of automobiles and performance. Bearing the name of the legendary Hans Mezger, this engine became intrinsically tied to the image of the Porsche 911 and it had a great deal to do with how the 911 became known as one of the most esteemed sports cars the world has to offer. In its time it was regarded very highly and is still recognized and respected for its capabilities and design.

Key Qualities of the Mezger Flat-Six:

• Legendary Porsche engine heritage
• Distinctive flat-six engine layout
• Proven motorsport performance record
• Exceptional engineering precision
