Speed devours fuel, even when it saves time.
As fuel prices continue their restless climb, a familiar tool has quietly grown more thoughtful. Google Maps now offers drivers the choice between the fastest path and the most economical one — a small but meaningful acknowledgment that the cost of movement is not merely measured in minutes. The feature, available to both combustion and electric vehicle drivers, invites a moment of reflection each time we set a destination: what, truly, are we optimizing for?
- Fuel prices keep rising, and the financial pressure on everyday drivers is mounting with each fill-up.
- Most users have been defaulting to the fastest route without realizing a fuel-saving alternative was quietly available all along.
- The trade-off is real — choosing efficiency can add several minutes to a journey, since slower regional roads burn less fuel than high-speed motorways.
- Drivers can act now: either manually select the efficient route each trip, or lock it in permanently under Settings > Navigation Preferences.
- The feature extends to electric vehicles too, where battery depletion at highway speeds mirrors the fuel drain of combustion engines.
Fuel prices rarely move in a driver's favor, and most of us have been navigating without the full benefit of the tools already in our hands. Google Maps has evolved well beyond a simple directions app — and one of its more practical recent additions lets you choose the route that burns the least fuel, not just the one that gets you there fastest.
The mechanics are simple: when you enter a destination, the app calculates which available route is most economical. That path is often not the quickest. A trip to Lisbon, for instance, might take nine extra minutes on the fuel-efficient route compared to the fastest one. The reason comes down to speed — motorways are fast but hungry, while regional roads, though slower, are easier on the tank. Electric vehicles follow the same logic, with battery drain accelerating at higher speeds.
By default, Maps still favors speed. To change that, drivers can either tap an alternative route manually each time, or head into Settings and configure Navigation Preferences to always prioritize efficiency. One adjustment, and the app begins defaulting to the economical option.
At its core, the feature frames a quiet but genuine trade-off: minutes versus money. Google Maps no longer makes that choice for you — it simply asks which one matters more. That the question is now being asked at all says something about how navigation tools are growing to reflect not just where we're going, but what it costs us to get there.
Fuel prices swing wildly week to week, almost always upward. Most of us carry a tool in our pockets that can help us fight back against that creeping cost at the pump—we just haven't been using it quite right. Google Maps, the navigation app that has quietly become something far more ambitious than a simple point-to-point guide, now does something genuinely useful: it can show you the route that will burn the least fuel.
The feature works straightforwardly. When you enter a destination, Google Maps identifies which available route demands the least from your tank. The catch, predictably, is that this efficient path is often not the fastest one. Take a drive to Lisbon. The most fuel-conscious option might add nine minutes to your journey compared to the quickest route. The reason is mechanical: highways move faster, and speed devours fuel. A route that's ninety percent motorway will drain your tank faster than one that sticks to regional roads, even if the latter takes longer. The same logic applies to electric vehicles—higher speeds mean faster battery depletion.
By default, Google Maps shows you the fastest route. If you want the thrifty option, you have two choices. You can tap the alternative routes displayed on your screen and select the fuel-efficient one each time you navigate. Or, better yet, you can make it your standing preference. Open Settings, then Navigation Preferences, and configure Maps to always prioritize fuel efficiency over speed. Once you've made that choice, the app will default to the economical route whenever you ask for directions.
The decision sits at the heart of a small but real trade-off: time versus money. For some drivers, nine extra minutes is a fair price for noticeably lower fuel costs. For others, the fastest route will always win. Google Maps now lets you choose which matters more to you, rather than deciding for you. The feature reflects a broader shift in how the app has evolved—from a simple navigation tool into something that touches on your driving habits, your budget, and your environmental footprint all at once. Whether drivers will actually use it remains an open question, but the option is there, waiting in your settings.

Why would someone choose a slower route when they're trying to get somewhere?
Because the fuel they save over time adds up to real money, especially when prices are volatile. Nine minutes on one trip doesn't matter much, but if you make that drive regularly, the tank fills up less often.
So it's not really about the environment then?
Not primarily, no. The feature helps the environment as a side effect, but the driver's motivation is usually their wallet. Though for electric car owners, it's about battery life, which is its own kind of cost.
Does Google Maps actually know how much fuel different routes burn, or is it guessing?
It's calculating based on road type and speed profiles. Highways are faster but thirstier. Regional roads are slower but more efficient. The app has enough data to make that distinction pretty reliably.
Why isn't fuel efficiency the default?
Because most people want the fastest route. Google optimizes for what the majority wants. If you care about fuel, you have to actively change your settings—it's not buried, but it's not automatic either.
Will this actually change how people drive?
For some, yes. For others, it won't matter. It depends whether someone values their time more than their money. The feature just makes the choice visible and easy to implement.
