3. Chrysler Slant-Six – The Angled Icon of Reliability
Chrysler’s Slant-Six, or G-Engine, carved a reputation as one of the most enduring inline-six engines in automotive history. Produced from 1959 to 2000, this canted 30-degree motor came in 170, 198, and 225 cubic-inch displacements, with torque delivery ideal for everything from sedans to vans.
Used in 31 different Chrysler, Dodge, and Plymouth models, its cast iron or aluminum blocks were known for withstanding neglect. Rugged yet simple, the Slant-Six could run forever with basic maintenance and was even adapted for motorsports. For torque lovers, its durability and flexibility across vehicle classes earned it near-mythical status.
4. Honda K-Series – Compact, Rev-Happy, and Tough
Honda’s K-Series engine family is often associated with high-revving performance, but it’s also a torque-capable, long-lasting platform. Introduced in 2001, these DOHC inline-fours ranged from 2.0 to 2.4 liters, delivering 150–320 horsepower depending on the application.
Found in everything from the Civic Type R to the CR-V and Acura TSX, the K-Series is a popular swap candidate due to its strong bottom-end torque and rev-friendly design.
The inclusion of VTEC adds efficiency without sacrificing longevity. Whether naturally aspirated or turbocharged, these engines consistently clock 200,000+ miles, proving small engines can deliver torque and longevity in one package.
5. Toyota 1JZ/2JZ – Turbo Torque and Iron-Clad Durability
The Toyota 1JZ and 2JZ inline-six engines are renowned in the performance community for their exceptional tuning potential and iron-clad reliability. Originally appearing in the early 1990s, these 2.5L and 3.0L engines were found in cars like the Supra, Soarer, and Chaser.
With cast-iron blocks and aluminum heads, they could handle substantial boost levels while offering factory torque figures from 168 to 320 hp—and beyond with modifications.
Even on stock internals, 2JZ engines have hit 1,000 hp reliably. For enthusiasts chasing both torque and bulletproof performance, few engines have earned more respect than the JZ family.

6. Mercedes-Benz OM617 – Diesel Longevity Redefined
Mercedes-Benz’s OM617 five-cylinder diesel engine, produced from 1974 to 1991, built a reputation around the world for long-lasting torque and reliability. Known for its use in European taxis and sedans like the W123 and W126, this cast-iron 3.0-liter motor often surpassed 500,000 miles.
Outputs ranged from 79 to 227 horsepower, with ample low-end torque typical of diesel configurations. Turbo variants added performance without sacrificing durability.
Mercedes even used it in record-setting prototypes like the C111. It’s this combination of effortless diesel torque and nearly indestructible construction that makes the OM617 a diesel icon.
7. Ford 300 Inline-Six – The Workhorse That Refused to Quit
The Ford 300 straight-six engine is synonymous with torque and unbreakable reliability. Introduced in the 1960s and used until 1996, it became the backbone of the F-Series pickups and numerous industrial vehicles.
With up to 150 horsepower but significantly more torque at low RPMs, it was ideal for towing, hauling, and utility applications. Its long-stroke design, forged components, and robust block earned it the nickname “indestructible” from truck owners.
Stories abound of these engines running without oil or lasting decades with minimal service. If raw torque and durability are the metrics, the Ford 300 is near unbeatable.
8. Toyota UZ V8 – Smooth, Strong, and Practically Eternal
Toyota’s UZ-series V8 engines, including the 1UZ, 2UZ, and 3UZ, are some of the most robust luxury and utility V8s ever made.
