Mazda Inline-6 Engine: Horsepower, Specs & How It Works
Mazda's 3.3-litre turbocharged Inline-6 combines smooth six-cylinder performance, responsive torque and mild-hybrid technology in the Mazda CX-70 and CX-90 SUVs.
Unlike conventional four-cylinder turbocharged engines, Mazda's e-Skyactiv G Inline-6 uses six cylinders arranged in a straight line. Paired with M Hybrid Boost, an eight-speed automatic transmission and standard i-ACTIV all-wheel drive, it delivers a distinctive driving experience.
What Is the Mazda Inline-6 Engine?
Mazda's Inline-6 is a turbocharged, 3.3-litre, six-cylinder gasoline engine developed for the brand's larger, rear-biased SUV platform.
An inline-six arranges all six cylinders in a single row, rather than dividing them into two banks like a V6. This arrangement offers excellent inherent mechanical balance, helping provide smooth power delivery and reduced vibration.
In Canada, Mazda pairs the 3.3L Inline-6 with its 48-volt M Hybrid Boost system, an eight-speed automatic transmission and standard i-ACTIV AWD.
Why Did Mazda Choose an Inline-6?
Mazda engineered its larger SUV architecture to accommodate a longitudinally mounted Inline-6. This arrangement supports the balanced handling, refined engine response and smooth acceleration Mazda wanted for the CX-70 and CX-90.
Mazda Inline-6 Engine Specs
Mazda offers standard-output and high-output versions of the 3.3L e-Skyactiv G Turbo engine, depending on vehicle and trim.
| Specification | Standard Output | High Output |
|---|---|---|
| Engine | 3.3L Turbo Inline-6 | 3.3L Turbo Inline-6 |
| Horsepower | 280 hp | Up to 340 hp |
| Torque | 332 lb-ft | 369 lb-ft |
| Hybrid System | 48V M Hybrid Boost | 48V M Hybrid Boost |
| Transmission | 8-speed automatic | 8-speed automatic |
| Drivetrain | i-ACTIV AWD | i-ACTIV AWD |
| Fuel for rated maximum horsepower | Regular gasoline | Premium gasoline |
High-output horsepower figures are based on recommended premium fuel. Specifications may vary by model, trim and model year.
How Much Horsepower Does the Mazda Inline-6 Make?
The standard-output 3.3L Turbo produces 280 horsepower and 332 lb-ft of torque. The high-output version produces up to 340 horsepower and 369 lb-ft of torque when using recommended premium gasoline.
With regular 87-octane gasoline, the high-output engine produces approximately 319 horsepower rather than its maximum 340-horsepower rating.
Does the Mazda Inline-6 Need Premium Gas?
Premium fuel is not required for every Inline-6 configuration. The standard-output version delivers its rated 280 horsepower on regular gasoline. The high-output version can run on regular gasoline, but premium fuel is recommended to achieve its maximum advertised horsepower.
Which Mazda SUVs Have the Inline-6 Engine?
In the Canadian lineup, Mazda offers the 3.3-litre turbocharged Inline-6 in two mild-hybrid SUVs: the Mazda CX-70 and Mazda CX-90. Both use the same fundamental engine architecture, but serve different lifestyles.
Mazda CX-70 Inline-6
The Mazda CX-70 combines turbocharged six-cylinder performance with seating for five and generous cargo capacity.
It suits drivers who want premium comfort, performance and space for luggage or equipment without needing a third row.
Mazda CX-90 Inline-6
The Mazda CX-90 combines the Inline-6 powertrain with three-row passenger versatility and standard all-wheel drive.
It is designed for drivers who need additional seating without giving up responsive performance and smooth highway driving.
Mazda CX-70 vs CX-90 Inline-6 Comparison
| Feature | Mazda CX-70 | Mazda CX-90 |
|---|---|---|
| Seating | 5 passengers | Up to 8 passengers |
| Rows | Two | Three |
| Inline-6 Engine | 3.3L Turbo | 3.3L Turbo |
| M Hybrid Boost | Standard with Inline-6 | Standard with Inline-6 |
| AWD | Standard | Standard |
| Main Advantage | Two-row cargo versatility | Three-row passenger seating |

Mazda Inline-6 vs V6: What's the Difference?
An Inline-6 and a V6 both use six cylinders, but their mechanical layouts are different.
The Inline-6 places its cylinders in one straight row, providing excellent natural balance and smooth power delivery. A V6 places its cylinders in two angled banks, creating a shorter engine package that can be easier to fit into some vehicle platforms.
Neither engine design is universally better. Mazda developed its larger SUV architecture around the longitudinal Inline-6 to achieve the driving characteristics it wanted.
Is the Mazda Inline-6 a Hybrid?
Yes. Mazda's Inline-6 powertrain includes a 48-volt M Hybrid Boost mild-hybrid system.
The system uses an electric motor and lithium-ion battery to support the gasoline engine and recover energy during driving.
Mild Hybrid vs Plug-In Hybrid
Mazda's Inline-6 MHEV does not need to be plugged in and is not designed for extended electric-only driving.
The Mazda CX-90 PHEV uses a different plug-in hybrid powertrain with a larger battery that can be charged externally.

How Does M Hybrid Boost Work?
M Hybrid Boost provides electrical assistance to the gasoline powertrain while recovering energy that can be stored in its battery.
It complements the characteristics of Mazda's turbocharged Inline-6, rather than replacing the gasoline engine with a full electric drivetrain.
Mazda Inline-6 Transmission, AWD & Towing
Eight-Speed Automatic Transmission
Mazda pairs the Inline-6 with an eight-speed automatic transmission engineered for its larger SUV platform. The powertrain is designed to deliver responsive acceleration and smooth performance across different driving conditions.
Standard i-ACTIV AWD
Canadian CX-70 and CX-90 Inline-6 models include standard i-ACTIV all-wheel drive, which manages torque distribution based on driving conditions.
For drivers in Woodstock, London and Oxford County, AWD offers useful traction support during changing Ontario road conditions. Appropriate tires remain essential for winter driving.
How Much Can a Mazda Inline-6 Tow?
Towing capability varies by SUV, trim and equipment. The CX-90 Inline-6 is rated for 3,500 lb on certain configurations, while select properly equipped versions can tow up to 5,000 lb.
Select Mazda CX-70 Inline-6 models are also rated to tow up to 5,000 lb when properly equipped.
Always confirm the applicable towing rating and equipment requirements for a specific vehicle.
Is the Mazda Inline-6 Engine Reliable?
Mazda's 3.3L Inline-6 is a relatively recent engine family compared with some of its long-running four-cylinder engines. As a result, long-term reliability data is still developing.
Engine longevity depends on factors including maintenance, driving conditions, operating temperatures and how the vehicle is used.
Following Mazda's recommended maintenance schedule, using approved engine oil and fluids, and maintaining the vehicle's cooling and electrical systems are important ownership practices.
Is the Mazda Inline-6 a Good Engine?
Mazda's Inline-6 is well suited to drivers looking for strong torque, smooth power delivery and a refined driving experience in a midsize or three-row SUV.
The standard-output version offers substantial performance for everyday driving, while the high-output configuration provides additional horsepower for drivers who prioritize acceleration and responsiveness.
