If you’re searching for the highest mpg luxury SUV, you’re not alone. Today’s luxury buyers want more than leather seats and premium tech—they also want fuel savings without giving up comfort. Thankfully, luxury brands are now offering hybrids and plug-in hybrids that deliver impressive MPG (or MPGe) while still feeling upscale, quiet, and powerful.
Even better, these fuel-efficient luxury SUVs are perfect for daily commuting, long road trips, and family driving. So, whether you prefer a compact crossover or a larger premium SUV, there’s a high-MPG option waiting for you.
What “Highest MPG” Really Means in Luxury SUVs
Before choosing the best model, it’s important to understand how mileage is measured.
MPG vs MPGe (Quick Explanation)
MPG (Miles Per Gallon): Used for gasoline and hybrid driving.
MPGe (Miles Per Gallon Equivalent): Used for plug-in hybrids and EV driving.
So, a plug-in hybrid might show extremely high MPGe because it can drive on electricity for short distances. However, once the battery ends, it behaves like a normal hybrid.
Therefore, the “highest MPG luxury SUV” depends on whether you want hybrid-only fuel savings or plug-in electric benefits too.
