MG HS Fuel Tank Capacity: Everything We Need to Know

When you’re out on the road—maybe cruising through Colombia, or planning a long highway trip in the UK—the size of your fuel tank isn’t just a number. It’s a part of your travel freedom. For the MG HS SUV, the fuel tank capacity tells us how far we can go between stops, what kind of driving rhythm we’ll have, and gives us a clue to the engineering choices behind the car. So let’s dig into the details, compare variants, and see how this spec plays out in the real world.

Why the Fuel Tank Capacity of the MG HS Matters

According to official specifications, the MG HS petrol version typically has a fuel tank capacity of 55 litres (L). This figure applies to most petrol and turbocharged models.

However, for the plug-in hybrid (PHEV) version of the MG HS, the fuel tank capacity is 37 litres. The smaller size makes sense, as hybrid models rely on their electric powertrain for part of the journey, reducing the need for a large petrol reserve.

When reviewing or buying the MG HS, it’s essential to know which version you’re looking at. The 55 L capacity applies mainly to the petrol model, while the PHEV’s 37 L tank changes how far you can go on fuel alone.

Putting 55 L Into Practical Perspective

Knowing the size of your tank is one thing—but what does it mean in real life?

If we assume the MG HS petrol version averages about 10 km per litre in mixed city-and-highway driving, then:

• 55 L × 10 km/L = roughly 550 km of range.
• On highways, where efficiency improves to around 12 km/L, the total range can stretch up to 660 km.

Of course, real-world numbers vary. Driving style, terrain, temperature, and load all affect how far that 55 L can take you.

If you’re planning a long trip—say, between Bogotá and Cali—you could expect to make one fuel stop during your journey. For the PHEV, even with its smaller 37 L tank, the electric mode compensates by covering shorter urban distances without petrol.

Why Did MG Choose a 55 L Tank?

This figure isn’t random—it reflects engineering balance. A 55 L tank provides a sweet spot between range and weight. Too small, and you’re constantly refueling; too large, and the car carries unnecessary weight.

Fuel adds mass: a full 55 L of petrol weighs about 40 – 45 kg. That extra weight influences acceleration, suspension tuning, and fuel economy. For the PHEV, the 37 L tank reduces that load while creating room for the battery pack, maintaining overall performance and handling.

How the MG HS Compares with Other SUVs

The MG HS sits comfortably in the middle of its class. Many compact SUVs feature tanks around 50 L, while larger mid-size models reach 60 L or more.

That means the MG HS doesn’t lag behind nor exceed expectations—it strikes a balanced middle ground. For drivers who value a mix of efficiency and practicality, this is a logical design choice.

Real-World Factors Affecting Your Range

Even with the same 55 L tank, your real-world range depends on several variables:

Driving Style:

• Rapid acceleration, frequent braking, or excessive idling waste fuel.
• Smooth, consistent driving maximizes efficiency.

Terrain and Conditions:

• Hilly or mountainous roads use more fuel than flat terrain.
• High altitudes (like those in many Colombian regions) can alter engine performance.

External Conditions:

• Temperature extremes impact fuel efficiency.
• Added cargo or passengers increase vehicle weight.

Powertrain Differences:

• Automatic transmissions can use more fuel than dual-clutch systems.
• PHEV models rely partly on electric motors, reducing petrol use but offering less tank capacity.

Tips to Maximize the Range of Your MG HS

There are several easy ways to make the most of every litre of fuel:

Adopt Smart Driving Habits

• Maintain steady speeds; avoid unnecessary acceleration.
• Use ECO or Normal driving modes for balanced performance.
• Anticipate traffic flow to minimize braking and idling.

Vehicle Care and Maintenance

• Keep tyres properly inflated.
• Remove roof racks or heavy items when not needed.
• Stick to regular maintenance schedules and clean air filters.

Trip Planning

• Check the distance to your destination versus your estimated range.
• Allow a buffer of 10–15 % for unplanned detours or traffic.
• For PHEV owners, charge your battery before long trips to extend range.

The Importance of Knowing Your Fuel Tank Size

Understanding your tank size goes beyond numbers—it’s about control. Whether driving across city streets or between distant towns, knowing your car’s limits helps you plan stops and manage costs.

For international buyers, especially in the UK or Europe, the MG HS’s 55 L tank is competitive and offers excellent value for mid-size SUV ownership.

For drivers in Latin America or Colombia, where fuel stations can be spaced far apart, this capacity brings peace of mind. The MG HS provides a good compromise between long-range travel and fuel economy.

Summary of Key Points

• Petrol MG HS: 55 litres fuel tank
• PHEV MG HS: 37 litres fuel tank
• Estimated range: 500–600 km depending on conditions
• Purpose: balanced between practicality, weight, and efficiency
• Comparison: competitive within compact-SUV class
• Tips: drive smoothly, maintain tyre pressure, plan stops wisely

Final Thoughts

Fuel tank capacity might not sound glamorous, but it plays a big part in your driving experience. For the MG HS, 55 litres means fewer refueling stops, steady long-distance comfort, and freedom on the road.

If you’re driving the plug-in hybrid, that 37 L tank paired with electric assistance provides a different kind of flexibility—perfect for city commutes and eco-minded travellers.

Whether it’s a daily commute or a weekend getaway, knowing how your MG HS fuel tank performs helps you travel smarter, safer, and farther.
