Comparing Fuel Costs: Gas vs Hybrid SUVs

SUVs are the go-to choice for families, offering space, comfort, and safety. But when it comes to running costs, the decision between a petrol (gas) model and a hybrid can have a big impact.

This guide helps you decide between a standard engine and a hybrid. It highlights the daily cost differences. You’ll find out how gas and hybrid SUV costs stack up. You’ll also see helpful fuel comparisons and learn what defines a best value SUV in 2025.

Understanding How Fuel Costs Add Up

Fuel is one of the biggest long-term expenses of SUV ownership. And while hybrids may offer better MPG, they’re not always cheaper outright.

Key Factors That Affect Fuel Costs:

• Miles per gallon (MPG) or litres per 100km
• Fuel prices in your region (petrol vs electricity rates)
• Type of driving (urban vs motorway)
• Weight and size of the SUV
• Driving habits (smooth vs aggressive acceleration)

Hybrids excel in city traffic, but petrol cars may do better on long highways.

The Basics: Petrol SUVs vs Hybrid SUVs

Let’s compare the two at a high level before diving into numbers.

Petrol (Gas) SUV:

• Traditional engine
• Lower upfront cost
• Simple refuelling
• Higher fuel consumption, especially in traffic

Hybrid SUV (HEV or PHEV):

• Combines petrol with electric motor
• Higher purchase price
• Lower running costs
• Quiet, efficient urban driving
• Some models can drive on electric power alone

Choosing between them depends on how far you drive, where you drive, and how long you plan to keep the vehicle.

Real-World Fuel Cost Comparison (2025)

Here’s how average fuel costs compare for similar-sized petrol and hybrid SUVs.

*Based on 12,000 miles/year, £1.50/litre petrol, average off-peak charging rates for PHEVs.

Savings Summary:

• A full hybrid can save around £500 per year
• A plug-in hybrid could save even more — £1,000 per year, if charged regularly

The longer you keep the vehicle, the greater the savings add up.

Initial Cost vs Long-Term Value

Hybrids typically cost more upfront — but that doesn’t mean they’re more expensive overall.

Example:

• Petrol SUV price: £32,000
• Hybrid equivalent: £35,000
• Fuel savings over 5 years: £2,500
• Net cost difference after fuel savings: £500

This difference may shrink more with incentives, lower maintenance, or higher resale value. These are all benefits that hybrids usually provide.

Other Running Costs to Consider

Fuel isn’t the only cost you’ll face. Let’s look at how hybrids and petrol SUVs compare elsewhere.

1. Maintenance

• Petrol SUVs have more wear on brakes and engines
• Hybrids use regenerative braking, reducing brake wear
• Fewer oil changes in hybrid systems
• Plug-in hybrids may need battery servicing over time

Winner: Hybrid, especially in the first 5 years.

2. Insurance

• Hybrids can cost slightly more to insure, due to higher vehicle value
• However, safety ratings and driver-assist features often reduce premiums

Winner: Depends on model and insurer — quotes vary.

3. Resale Value

• Hybrids currently hold value better due to high demand
• Buyers are prioritising fuel efficiency more than ever
• Petrol SUVs may drop in value faster as emission standards tighten

Winner: Hybrid, in most cases.

Who Should Choose a Petrol SUV?

Not every driver needs a hybrid. A petrol SUV still suits many family needs.

Choose Petrol If:

• You drive long distances on motorways often
• You don’t have access to home or workplace charging
• You plan to sell the vehicle within 2–3 years
• You’re buying a used SUV on a tighter budget

For short ownership or high-mileage trips, a good petrol model can still be smart.

Who Benefits Most from a Hybrid SUV?

Families that stay local or drive in city traffic can gain the most from hybrid technology.

Choose Hybrid If:

• You mostly drive in cities or on short trips
• You value long-term savings over upfront costs
• You want lower emissions and better fuel economy
• You’re planning to keep the SUV for 5+ years
• You want a quieter, smoother ride

Plug-in hybrids offer even greater savings — but only if you plug in regularly.

Hidden Benefits of Hybrids for Families

It’s not just about money. Hybrid SUVs offer everyday advantages that families really notice.

Daily Perks Include:

• Less engine noise (great for sleeping kids)
• Instant torque for smooth acceleration
• Fewer fuel stops — handy on road trips
• Environmentally friendlier driving
• Often come with more advanced safety features

The driving experience feels smoother and more relaxing, even before you see the savings.

How to Maximise Your SUV’s Fuel Efficiency

Whether you choose petrol or hybrid, you can still lower your fuel costs.

Smart Driving Tips:

• Use Eco Mode when possible

• Don’t idle for long periods
• Remove roof racks when not needed
• Limit use of aircon and heated seats

Simple changes can improve MPG by 10–15% — regardless of the engine.

Value Isn’t Just What You Pay Upfront

When choosing between a petrol and a hybrid SUV, consider more than just the price tag. Think about the total cost of ownership. In the battle of gas vs. hybrid SUV costs, hybrids usually win in the long run. This is true, especially with rising fuel prices and a move toward cleaner driving.

Compare not just MPG but overall running costs, daily comfort, and family convenience. When you do, the best value SUV may surprise you — and save you more than just money.
