Six cylinder engines still represent one of the best formulas in the automotive world. They offer smooth power delivery, real durability, fewer vibrations than a four cylinder and none of the complexity that plagues modern turbocharged drivetrains. In a country like Canada, where engines must survive brutal winters, long commutes, steep grades and constant temperature swings, only a handful of six cylinder engines have earned reputations as genuinely bullet proof. These engines have proven themselves over decades, across provinces and through every kind of driving condition. Here are the ten six cylinder engines Canadians can trust to outlast the cars they power, along with the vehicles that carry them.
Honda J35 V6 in the Honda Pilot, Honda Ridgeline and Honda Passport
The J35 has become a symbol of reliability in Canada. It is smooth, torquey and resistant to the cold start stresses that destroy lesser engines. Owners routinely see these motors cross four hundred thousand kilometers without needing major work. The J35 also handles towing and long highway travel with surprising ease. In trucks like the Ridgeline it offers V8 like refinement without the downside of thirsty fuel habits. In family vehicles like the Pilot it delivers dependable power for years with little more than routine oil changes and timing belt service.
Buick 3800 V6 in older Buick, Pontiac and Oldsmobile sedans
The Buick 3800 remains one of the most durable North American engines ever built. It thrives in harsh weather, tolerates less than perfect maintenance and keeps starting even after years of winter punishment. Canadians particularly love this engine because it simply refuses to quit. It appears in older Buicks and Pontiacs that still roam highways today with odometers showing mileage that should have retired them long ago. The 3800 may not be fast or high tech, but it delivers the kind of old school dependability that newer engines often lack.
Jeep 4.0 Inline Six in the Jeep Wrangler and Jeep Cherokee
The Jeep 4.0 is legendary among off road and rural Canadian drivers. This engine seems almost immune to abuse. It survives cold starts at minus thirty, long idling sessions on job sites and slow crawling trails that punish cooling systems. The engine’s simple design and cast iron durability make it one of the easiest six cylinders to maintain. When a Wrangler or Cherokee has the 4.0 under the hood, owners know the engine will almost always outlive the body.
Ford 3.5 Cyclone V6 in the Ford Explorer, Ford Edge and earlier Ford F150
Ford’s naturally aspirated 3.5 V6 is the dependable counterpart to the more complicated EcoBoost engines. It offers strong torque, predictable maintenance needs and a calm temperament in cold climates. In an F150 it provides plenty of usable power without the mechanical stress of turbocharging. In family vehicles like the Explorer and Edge, the engine is known for smoothness and longevity. Many Canadian owners choose this engine specifically because it avoids the complexity of modern forced induction while still delivering real everyday performance.
Toyota 2GR FE V6 in the Toyota Highlander, Toyota 4Runner and Lexus RX
The 2GR FE has earned its place among the best modern six cylinder engines. It is incredibly smooth, powerful enough for towing and surprisingly efficient for its size. In Canada it shines during winter starts and long highway stretches. Drivers routinely report these engines crossing three hundred thousand kilometers with no internal failures. Vehicles like the Lexus RX and Toyota Highlander feel almost indestructible with this V6, while the 4Runner benefits from its strong mid range torque when climbing steep terrain or navigating rugged northern roads.
Mercedes Benz M112 V6 in older C Class and E Class models
The M112 is one of the most durable engines Mercedes ever built. It offers a blend of refinement and longevity that modern turbo engines cannot always match. Canadian buyers like the M112 because it tolerates winter driving, short commutes and long distance travel without wearing out prematurely. It is also relatively easy to service compared with newer European engines. For anyone wanting a luxury sedan without the fear of catastrophic repair bills, an older Benz with the M112 is a surprisingly safe bet.
Chrysler Slant Six in classic Dodge and Plymouth models
Though no longer produced, the Slant Six deserves its place on this list because so many examples still operate across Canada. This engine is famous for refusing to die. It starts in the cold, tolerates years of neglect and functions in environments that would destroy more delicate powertrains. Classic car owners and farm drivers respect the Slant Six because it represents an era of bullet proof engineering that valued strength over complexity.
Ford 300 Inline Six in classic Ford trucks and vans
Known for unbelievable torque and a reputation for indestructibility, the Ford 300 is a favorite among classic truck owners. It is a workhorse engine designed to pull, haul and run nonstop regardless of weather. Many examples in Canada are still used as working farm trucks or winter beaters, proving their toughness across decades. It is the kind of engine that keeps running even when everything else on the vehicle is worn out.
Nissan VQ Series V6 in the Nissan Maxima, Infiniti G35 and 350Z
The VQ engine family continues to impress Canadian drivers for its combination of performance and ruggedness. Whether found in sporty models like the Infiniti G35 or practical sedans like the Maxima, it delivers consistent reliability even in tough climates. Cold starts do not bother it, long drives do not fatigue it and owners regularly push these engines well past three hundred thousand kilometers. The VQ remains a favorite among enthusiasts because it blends smoothness, power and durability in a way few modern engines can match.
Toyota 2JZ GE Inline Six in older Lexus IS300 and Toyota models
The 2JZ GE is the naturally aspirated sibling of the legendary Supra turbo engine. While the turbo models get the fame, the GE variant is often even more durable due to lower stress and simpler internals. Canadian owners appreciate the 2JZ for its buttery smooth operation, effortless longevity and bullet proof construction. These engines rarely fail and can accumulate enormous mileage with nothing more than basic maintenance. Finding one today is harder, but it remains one of the finest straight six engines ever sold in Canada.
Why These Six Cylinder Engines Still Matter
Six cylinder engines offer a perfect balance in a world filled with tiny turbos and complicated hybrid systems. They are smooth, reliable and resilient in Canadian conditions that punish lesser engines. Many modern cars chase efficiency at the expense of durability, but these engines prove that longevity still exists. They survive harsh winters, long commutes, rural roads and everything in between. For Canadian buyers who want vehicles that last, these engines represent some of the safest bets on the road.
