Which Subaru has 6 cylinder engine?

Subaru currently does not offer a factory six-cylinder engine in its new models. Historically, a few models used flat-six engines, but today six-cylinders are found only in older/Subaru second-hand offerings.

Historical six-cylinder Subarus

Subaru did produce several six-cylinder (boxer-six) engines in the past. The main examples were the Tribeca, which used a 3.0-liter flat-6, and the Legacy/Outback lines that offered a 3.6-liter flat-6 in higher-trim variants.

Below are the Subaru models that used a six-cylinder engine in the past. Note these are not offered new today.



• Subaru Tribeca (2005–2014) with the 3.0-liter EZ30 flat-6 engine


• Subaru Legacy and Outback (late 2000s to early 2010s) with the 3.6-liter EZ36 flat-6 engine, including higher trims such as 3.6R

These six-cylinder Subarus are now primarily seen on the used-car market. If you want a six-cylinder Subaru today, you would be looking at older models from those generations.

Current lineup and possibilities

In recent years Subaru’s engineering focus has been on four-cylinder engines, including turbocharged variants, across the main passenger lineups. As of 2024–2025, there are no new Subaru models equipped with a factory six-cylinder engine.

Engine options and performance notes

The contemporary Subaru approach emphasizes horizontally opposed four-cylinder engines (often with turbocharging in performance-oriented models) for improved efficiency and packaging. For customers seeking more power, the brand’s turbo four-cylinder offerings provide strong performance without adopting a six-cylinder configuration.

How to identify a six-cylinder Subaru (if shopping used)

When evaluating used Subarus for a six-cylinder powerplant, look for engine codes and badges that indicate a flat-six, such as EZ30 or EZ36, and watch for model names or trim indicators like “3.6R” or “3.0R” that point to a six-cylinder option.

Check the VIN and build sheet to confirm engine displacement, and review service history for documentation of a six-cylinder engine or related maintenance items specific to a flat-6 configuration.

Summary

Historically, Subaru offered six-cylinder engines in the Tribeca (3.0L EZ30 flat-6) and in certain Legacy/Outback trims (3.6L EZ36 flat-6, including 3.6R). Today’s lineup does not include a new six-cylinder option; buyers interested in six cylinders should consider used examples from those generations or explore the brand’s four-cylinder engines for comparable performance.

Does the Subaru Outback come in a six-cylinder?

With the arrival of the third generation Legacy, the second generation Outback wagon became its own model. The Legacy SUS remained unique to North America and was realigned with the Outback Limited package, offering the sedan with an optional horizontal six-cylinder engine, also optional on the wagon.

Is the Subaru 3.6 engine any good?

The 3.6 has adequate power that it's a non-issue but you'll never confuse it with a fast vehicle either... It's just the bare minimum to drive around and not want to bang your head into the steering wheel. The EZ36 is generally regarded as one of the best engines Subaru have produced.

Is a Subaru Forester a 6-cylinder?

No, the Subaru Forester does not come in a 6-cylinder engine; it has exclusively used a 2.5-liter 4-cylinder boxer engine in recent model years. The 6-cylinder engine is offered in other Subaru models, such as the larger Outback and Legacy, but not the Forester. 

• Forester engine: The Forester is equipped with a 2.5-liter four-cylinder horizontally opposed "boxer" engine. 
• Other models: Subaru's 6-cylinder engines are found in larger vehicles like the Outback and Legacy, though higher trims of the Outback may offer a turbocharged 2.4-liter four-cylinder instead. 
• Historical context: Some older, high-performance versions of the Forester (like a 2004 model with a turbocharged 2.5L) had more power than some 6-cylinder engines, but the standard models did not have 6 cylinders. 

Is it better to have a 4 cylinder or 6-cylinder?

Neither is definitively better; a 6-cylinder engine generally offers more power and smoothness, making it ideal for performance or heavy-duty applications, while a 4-cylinder is usually better for fuel efficiency and is more common in smaller, cost-effective cars. The "better" engine depends on what you prioritize, such as power, fuel economy, or cost.

6-cylinder engines

• Pros: More horsepower and torque, better for towing and hauling, generally smoother and quieter operation. 
• Cons: Worse fuel economy, higher cost to purchase and maintain. 
• Best for: Performance vehicles, SUVs, trucks, and drivers who need to tow or who prioritize a smoother, quieter ride. 

4-cylinder engines

• Pros: Better fuel economy, lower purchase cost, smaller and lighter. 
• Cons: Less power and torque, can feel less smooth than a 6-cylinder, especially without turbocharging. 
• Best for: Commuting, city driving, and budget-conscious buyers who want better fuel efficiency.

The role of turbocharging

• Increased power: Modern 4-cylinder engines are often turbocharged, which can give them power outputs comparable to naturally aspirated 6-cylinders. 
• Compromise: A turbocharged 4-cylinder can provide a good balance of power and fuel efficiency, though it may not offer the same level of smoothness as a 6-cylinder.
