The V8 engine has always stood as a symbol of strength, durability, and pure driving exhilaration. Known for its unmistakable growl and muscular performance, the V8 is a favorite in everything from rugged trucks to refined luxury sedans. Yet, longevity is where the true legends are separated from the rest.
While many V8s deliver impressive power, only a select few can rack up well over 300,000 miles with proper care. This list dives deep into ten V8 engines renowned not just for their power, but for their exceptional endurance—engines that have proven themselves as long-lasting workhorses in the real world.
1. Chevrolet LS3 – GM’s Legendary Workhorse
The LS3 is one of General Motors’ best-known V8s, famous for its simplicity, affordability, and reliability. Introduced in 2008, it served various GM models like the Chevrolet Corvette and the Holden Commodore. With a 6.2-liter displacement, it delivers between 415 and 430 horsepower and about 420 lb-ft of torque.
The LS3 is a favorite in the aftermarket due to its availability as a crate engine. Though some users report oil consumption issues, many engines have surpassed 250,000 miles with routine maintenance. It remains one of the best V8s for performance and longevity at a reasonable price point.
2. Mercedes-Benz M113K – German Muscle with Durability
The Mercedes-Benz M113K, a supercharged version of the M113, powered AMG models like the E55 and CL55. Producing between 476 and 582 horsepower, it was built to compete with high-end sports cars while retaining daily drivability.
Known for its robust internals, the M113K handles modifications well and rarely suffers from factory defects. Most issues arise when owners skip scheduled maintenance.
Even with forced induction, this engine has proven to exceed 150,000 miles with ease, showing AMG’s attention to performance and reliability. It is also known for offering immense power in a relatively understated luxury package.
3. BMW S63 – A Turbocharged Turnaround
Initially plagued by mechanical problems, BMW’s S63 4.4-liter twin-turbo V8 has matured into a formidable and dependable powerplant. Found in high-performance models like the M5 and X5M, it delivers up to 625 horsepower in later configurations.
BMW addressed early flaws such as turbocharger and connecting rod issues through successive revisions. The engine now stands among the most advanced and powerful V8s on the road.
Nevertheless, it’s essential to maintain it meticulously. The S63’s reliability improves substantially with timely service, although some BMW-typical issues like oil leaks remain. When well-maintained, it’s a thrilling engine that rewards enthusiast drivers.
4. Toyota 2UR-GSE – Lexus Precision and Longevity
Developed in partnership with Yamaha, Toyota’s 2UR-GSE is a naturally aspirated 5.0-liter V8 designed for Lexus F-models. Producing between 416 and 475 horsepower, it powers vehicles like the RC-F and IS 500.
Renowned for its smooth delivery and high-revving nature, the engine combines performance with Toyota’s legendary durability. The 2UR’s architecture ensures minimal mechanical wear, and many units exceed 200,000 miles without significant issues.
Some owners report mild oil consumption, but otherwise, it’s a low-maintenance, high-output motor. It lacks the forced induction of rivals but makes up for it with a linear powerband and exceptional reliability.
5. Chrysler HEMI 6.4 – Old-School Brawn with Modern Woes
The Chrysler HEMI 6.4-liter V8, featured in muscle cars and trucks, provides 470–485 horsepower and 470–475 lb-ft of torque. Its roots lie in classic American V8 engineering, but modern iterations suffer from a critical flaw—Multi-Displacement System (MDS) failure.
The MDS deactivates cylinders to improve fuel economy, but can cause valve seats to drop, leading to catastrophic engine failure. Enthusiasts often disable MDS to avoid this.
Otherwise, the engine has solid potential and has been reported to reach over 220,000 miles. It’s powerful and iconic, but requires vigilance and proactive maintenance to stay reliable long-term.

6. Toyota 1UZ-FE – The Million-Mile Marvel
Debuting in the Lexus LS400, the Toyota 1UZ-FE is frequently cited as the most reliable V8 engine ever produced. It delivers 256–300 horsepower and up to 310 lb-ft of torque. Built with overengineering in mind, it features a forged steel crankshaft and strong internals.
Real-world examples have exceeded one million miles without major repairs, a testament to its incredible durability. Problems are rare and usually stem from neglect, like skipped timing belt replacements.
Toyota’s meticulous design and attention to detail make the 1UZ-FE a paragon of V8 longevity, earning it a permanent place in the reliability hall of fame.
7. Chevrolet Small-Block 350 – A Hot-Rod Favorite
The Chevrolet 350 small-block V8 is a cornerstone of American performance history. It has powered everything from Corvettes to pickup trucks since 1967 and remains popular for restomods and hot rods.
With outputs between 155 and 425 horsepower, it’s incredibly versatile and easy to work on. Its affordability and parts availability make it ideal for DIY mechanics.
However, overheating can occur if the thermostat or cooling system isn’t properly maintained. Despite this, it routinely reaches 180,000 miles or more. The 350 isn’t just reliable—it’s a symbol of the American car culture that still thrives today.
8. Ford Coyote – Modern Performance with Some Gremlins
Ford’s Coyote 5.0 V8 is the heart of modern Mustangs and F-150s, offering 412 to 500 horsepower and robust torque. Introduced in 2010, it evolved from Ford’s Modular V8 family and features advanced dual overhead cam architecture.
It’s capable of high RPMs and strong output, but early models had ignition coil issues and head gasket leaks. Later versions fixed these problems, and the engine has since proven durable, with some reaching 288,000 miles.
It’s a favorite for performance tuners and track-day enthusiasts. With regular care, the Coyote V8 offers thrilling power without sacrificing daily reliability.
9. Hyundai Tau 5.0 – Korean V8 Ambition
Hyundai’s Tau 5.0 V8, used in luxury models like the Genesis and Equus, marked the brand’s entry into premium performance territory. Offering up to 419 horsepower and 383 lb-ft of torque, the Tau engine was well-balanced but had early teething issues.
Between 2012 and 2014, some engines suffered from excessive oil consumption. These problems were later addressed by Hyundai, and well-maintained examples have reached over 230,000 miles.
The Tau showcases Hyundai’s growth in engineering, but it never achieved the bulletproof status of Japanese rivals. It’s dependable now, but potential buyers should verify that past issues were resolved.
10. Toyota 3UR-FE – Truck-Grade Reliability
Used in Toyota’s Tundra, Land Cruiser, and Sequoia, the 3UR-FE is a 5.7-liter V8 known for its ruggedness and torque. Producing 381 horsepower and 402 lb-ft of torque, this engine also had optional supercharger kits that pushed output beyond 500 hp.
It’s built for heavy-duty use and can easily surpass 300,000 miles. That said, it has some minor issues, such as cam tower oil leaks and water pump failures. Most of these are manageable with routine maintenance.
The 3UR-FE’s combination of power and longevity makes it a favorite among truck enthusiasts and overlanders looking for unmatched endurance.
The world of V8 engines is vast, ranging from race-ready supercharged beasts to dependable family haulers. While names like Toyota and GM dominate the list of reliable choices, even engines with rocky starts—like BMW’s S63—can shine with the right care.
Others, like Chrysler’s HEMI, showcase old-school muscle that can backfire without attention to detail. Whether your priority is performance, modifiability, or durability, understanding each engine’s strengths and weaknesses is key.
With this information in hand, buyers and enthusiasts alike can make informed decisions and enjoy the thrills of a V8 without the pitfalls of poor reliability.
