Mazda CX-5 G20 vs G25: Which Engine Is the Better Choice for Your Drive?

The Mazda CX-5 has earned a reputation as one of the most refined midsize SUVs on the market. With elegant styling, premium-feeling interiors, and engaging driving dynamics, it often feels like a luxury vehicle without the luxury price tag. Yet one question consistently appears among buyers: should we choose the Mazda CX-5 G20 or the G25?

At first glance, the difference seems simple. One has a 2.0-liter petrol engine, while the other uses a larger 2.5-liter unit. However, the real-world experience goes much deeper than engine displacement. Performance, fuel economy, comfort, resale value, towing capability, and long-term ownership costs all play a role.

In this comprehensive comparison, we will break down every important aspect of the Mazda CX-5 G20 versus G25 to help determine which version deserves a spot in your driveway.

Understanding the Mazda CX-5 Engine Range

Before comparing the two models, it's important to understand Mazda's naming convention.

The "G" stands for gasoline (petrol), while the number refers to engine size:

• G20 = 2.0-liter Skyactiv-G petrol engine
• G25 = 2.5-liter Skyactiv-G petrol engine

Both engines are naturally aspirated, meaning they do not use turbochargers. Mazda has traditionally favored larger-capacity naturally aspirated engines that provide smooth and predictable power delivery.

This approach creates a driving experience that feels linear, refined, and confidence-inspiring.

Mazda CX-5 G20 vs G25 Quick Comparison

The table immediately reveals the biggest distinction: the G25 produces significantly more power and torque.

Why Engine Size Matters More Than You Think

Many buyers focus exclusively on fuel consumption figures. While efficiency is important, engine size impacts much more than how often we visit the fuel station.

A larger engine affects:

• Acceleration
• Highway overtaking
• Passenger comfort
• Towing ability
• Hill climbing
• Vehicle responsiveness

The G25 provides more effortless performance in nearly every driving situation.

The difference feels similar to riding a bicycle with an electric assist. Both will get you where you need to go, but one requires noticeably less effort.

Performance Comparison

Mazda CX-5 G20 Performance

The G20 engine delivers approximately 115 kW and 200 Nm of torque.

In everyday city driving, this output feels perfectly acceptable. The vehicle pulls away smoothly and remains refined in urban traffic.

However, once we begin carrying multiple passengers or luggage, the limitations become more noticeable.

Acceleration is respectable but not exciting.

Mazda CX-5 G25 Performance

The G25 raises output significantly to around 140 kW and 252 Nm.

This extra power transforms the CX-5.

The SUV feels more responsive when:

• Joining highways
• Overtaking slower traffic
• Driving through mountainous terrain
• Carrying a full family

The improvement isn't subtle. The additional torque provides stronger low- and mid-range acceleration.

Performance Winner

Winner: Mazda CX-5 G25

The G25 offers noticeably stronger performance without compromising refinement.

Real-World Driving Experience

City Driving

In urban environments, both engines perform admirably.

The G20's lighter fuel consumption can be attractive for commuters who spend most of their time navigating traffic lights and congestion.

Meanwhile, the G25 feels more relaxed because it requires less throttle input.

Highway Driving

The highway is where the G25 truly shines.

When overtaking a truck or accelerating up an incline, the larger engine feels effortless.

The G20 can accomplish the same tasks but typically requires higher revs and more planning.

Long-Distance Touring

For road trips, the G25 offers a more comfortable driving experience.

Less strain on the engine means:

• Lower stress levels
• Better overtaking confidence
• Smoother progress
• Improved passenger comfort

Fuel Economy: Is the G20 Really More Efficient?

One of the primary reasons buyers consider the G20 is fuel efficiency.

G20 Fuel Consumption

The G20 generally delivers slightly better official fuel economy figures.

This advantage stems from:

• Smaller displacement
• Lower power output
• Reduced fuel demand

G25 Fuel Consumption

The G25 consumes marginally more fuel.

However, the difference is often smaller than many buyers expect.

In real-world driving, the gap may be only a fraction of a liter per 100 km.

The Surprising Reality

Many drivers discover that the G25 doesn't use dramatically more fuel because it doesn't need to work as hard.

The larger engine often operates more efficiently under load.

Fuel Economy Winner

Winner: G20 (slightly)

The advantage exists, but it's rarely large enough to be the deciding factor.

Acceleration and Responsiveness

Standing Start Performance

The G25 launches more confidently from traffic lights.

Throttle response feels immediate and eager.

Mid-Range Acceleration

Mid-range power matters more than outright speed in everyday driving.

The G25's extra torque provides:

• Faster overtakes
• Quicker lane changes
• Better merging ability

Engine Flexibility

The G25 offers greater flexibility because it can accelerate strongly without requiring aggressive downshifts.

This creates a smoother driving experience.

Towing Capability Comparison

Mazda CX-5 G20 Towing

The G20 can handle light towing duties.

Suitable examples include:

• Small trailers
• Utility trailers
• Lightweight recreational equipment

Mazda CX-5 G25 Towing

The G25 is considerably better suited to towing.

The additional torque helps maintain momentum and stability.

For buyers planning to tow regularly, the G25 is the clear recommendation.

Ride Comfort and Refinement

One overlooked factor is how engine performance influences comfort.

G20 Refinement

The G20 remains smooth and refined during normal driving.

However, it occasionally needs to work harder when:

• Climbing steep grades
• Carrying heavy loads
• Accelerating quickly

G25 Refinement

Because the G25 produces more torque, it often operates at lower engine speeds.

This results in:

• Reduced engine noise
• Less vibration
• More relaxed cruising

The driving experience feels more premium overall.

Ownership Costs Beyond Fuel

Many buyers focus solely on fuel bills.

Yet total ownership costs include:

• Insurance
• Maintenance
• Tires
• Depreciation
• Registration

Interestingly, maintenance costs between the G20 and G25 are generally very similar.

This means the larger engine's advantages often outweigh its modest increase in fuel consumption.

Which Engine Is Better for Families?

Families typically prioritize practicality and comfort.

The G25 delivers advantages in several areas:

• Better loaded performance
• Easier highway travel
• Improved towing capability
• More relaxed long-distance driving

If your CX-5 will regularly carry children, luggage, or sports equipment, the G25 is usually the smarter choice.

Resale Value and Future Demand

Resale value can significantly impact long-term ownership costs.

G20 Resale Outlook

The G20 remains popular among budget-conscious buyers.

However, demand may be slightly lower in the used market.

G25 Resale Outlook

The G25 generally enjoys stronger buyer demand.

Many used-car shoppers actively seek the more powerful engine.

As a result, resale values often remain stronger.

Resale Winner

Winner: G25

Higher demand typically supports better retained value.
