Real MPG: The Most Efficient Used SUVs You Can Buy

When it comes to choosing a used SUV, fuel efficiency is a key factor for many buyers. With fuel prices fluctuating and environmental concerns growing, drivers are looking for vehicles that deliver strong real MPG, a measure of how a car performs in real-world driving conditions, rather than just relying on official test figures.

But what exactly is real MPG, and which used SUVs offer the best efficiency? Let’s take a closer look.

What Is Real MPG?

Real MPG refers to the actual miles per gallon a vehicle achieves in everyday driving, on motorways, city streets and mixed routes. This figure is often lower than the manufacturer’s stated MPG due to variables like driving style, traffic conditions and weather.

For used SUV buyers, choosing a model with a strong true MPG can mean lower running costs and fewer stops at the petrol station. Here's a list of the ones we think are most efficient

1. Vauxhall Grandland

The Vauxhall Grandland is a popular family SUV, offering a plug-in hybrid (PHEV) option that delivers impressive efficiency. The petrol and diesel models also perform well, with real MPG figures often surpassing circa 45 mpg on longer journeys.

Best for Families looking for a spacious and fuel-efficient SUV.

2. CUPRA Formentor

CUPRA’s Formentor is a performance-focused SUV, but that doesn’t mean it’s inefficient. The 1.5 TSI petrol model delivers up to 42 real MPG, while the plug-in hybrid version (e-Hybrid) can achieve even better economy if driven in electric mode.

Best for: Drivers who want a stylish, sporty SUV without sacrificing fuel economy.

3. Peugeot 3008

The Peugeot 3008 has long been praised for its design and practicality, but it’s also one of the most fuel-efficient SUVs in real-world conditions. The 1.5 BlueHDi diesel model achieves around 50 real MPG, making it a great option for those who do a lot of motorway miles.

The plug-in hybrid (PHEV) version offers electric-only driving for short commutes, further improving efficiency.

Best for:Commuters and long-distance drivers looking for a refined, efficient SUV.

4. Mazda CX-5

Mazda’s CX-5 is known for its premium feel and excellent driving dynamics. Thanks to Skyactiv technology, the 2.2 Skyactiv-D diesel model achieves up to 47 Real MPG, making it a solid choice for those who need a practical yet fuel-efficient SUV.

Best for: Drivers who want an engaging SUV with excellent real-world efficiency.

5. MG ZS

For those looking for an affordable used SUV, the MG ZS delivers solid Real MPG numbers, particularly in the petrol models. The 1.0 turbocharged engine can return up to 42 mpg, making it a cost-effective choice.

For ultimate efficiency, the MG ZS EV (electric version) removes fuel costs altogether while offering a strong range per charge. Best for: Budget-conscious buyers who still want SUV practicality.

If fuel efficiency is high on your list of priorities, these offer some of the best real MPG figures in their class. Whether you’re after a diesel for long-distance efficiency, a hybrid for city driving or an affordable petrol SUV, there’s a model that fits your needs.
