In a world where planned obsolescence seems to be the norm, some automotive engines continue to fascinate with their exceptional longevity. These legendary engines have survived the decades while maintaining unfailing reliability, delighting enthusiasts and drivers looking for durability. Discover the secrets of these exceptional engines that have marked the history of the automobile.
The Toyota 2JZ-GTE: the eternal Japanese straight-six
Among the most iconic engines in automotive history, the Toyota 2JZ-GTE holds pride of place. This 3.0-liter inline six-cylinder, fitted in particular to the legendary Supra, is renowned for its ruggedness in all conditions.
Originally designed to develop 280 horsepower, this block can easily reach much higher power outputs without compromising its reliability. Prepared examples have exceeded the 1000 horsepower mark while retaining the original block. This ability to withstand extreme constraints has earned it a place of choice in tuning culture and motor sports.
The Volkswagen Type 1: simplicity in the service of longevity
At the opposite end of the performance spectrum is the Volkswagen Beetle's engine. This small, air-cooled flat-four, with an initial displacement of just 1.1 liters, powered millions of vehicles for over 60 years.
Its minimalist design, with a reduced number of moving parts, makes it a model of reliability. Many examples have exceeded a million kilometers without major overhaul. Its simplicity also allows easy repairs, even for an informed amateur, thus contributing to its exceptional longevity.
The Mercedes-Benz OM617: the indestructible diesel
In the field of diesel engines, the Mercedes-Benz OM617 has established itself as an absolute benchmark in terms of reliability. This 3.0-litre five-cylinder in-line engine, produced from 1974 to 1991, equipped many models of the brand with the star.
Its robust construction, with a cast iron block and an aluminum cylinder head, allows it to withstand astronomical mileages. It is not uncommon to see examples that have covered more than a million kilometers without major intervention. Its flexibility and generous torque also make it a pleasant engine to use on a daily basis.
The BMW M20: the Bavarian stallion
BMW also has its place in this ranking with the M20 engine. This six-cylinder in-line, produced from 1977 to 1993, powered many of the brand's models, including the famous 3 Series and 5 Series.
Renowned for its smooth operation and its frank revs, the M20 also stands out for its unfailing reliability. Its robust design allows it to withstand high mileages without flinching. In addition, its relative mechanical simplicity makes it easy to maintain, contributing to its longevity.
The Honda B18C: the high-performance four-cylinder
Honda has built its reputation on compact, high-performance engines, of which the B18C is a perfect example. This 1.8-litre four-cylinder, fitted in particular to the Integra Type R, combines high performance with exceptional reliability.
Capable of revving to over 8000 rpm in series, this block supports high revs without flinching. Its careful design, with high quality materials, allows it to maintain its performance even after hundreds of thousands of kilometers. Many enthusiasts still use it today in competition, proof of its robustness.
