BMW X5 vs Mercedes GLE: Two of the Best Luxury PHEVs Go Head to Head But Only One Wins

If you're in the market for a large luxury SUV and you've been quietly wondering whether a plug-in hybrid might actually make sense for your life, this is the comparison you've been waiting for.

The BMW X5 xDrive50e and the Mercedes-Benz GLE 450e are two of the finest midsize luxury SUVs money can buy, and crucially, they're among the very few in their class that let you plug in and run on pure electric power for everyday errands. The team at Edmunds put both through their paces to find out which one deserves your money. Here's what they found.

The Basic Idea Behind Both Cars

Both of these PHEVs work the same way in principle. Charge up the battery at home, drive the first chunk of your day on electricity alone, and then let the petrol engine take over seamlessly when the battery runs low. If most of your daily driving stays under 40 miles and you can plug in regularly at home, you could go weeks barely touching the fuel pump. It's a genuinely compelling proposition, all the range and reassurance of a traditional engine, with the running costs of something much closer to an EV for everyday use.

The question isn't really whether these cars are good. They both clearly are. The question is which one is better, and the answer depends quite a bit on what you actually want from a car.

Inside: Mercedes Takes the Crown

Step into the GLE 450e and you'll immediately understand why Mercedes has such a devoted following. The cabin is spacious, beautifully finished, and genuinely relaxing in a way that makes long journeys feel effortless. Heated, ventilated, and massaging seats combined with an excellent climate control system mean that by the time you arrive somewhere, you feel better than when you left. The back seat has generous room for child safety seats, too, with anchor points that are easy to reach and use.

The BMW's interior is no slouch; it has premium materials, near-infinite seat adjustment, LED ambient lighting, and a vault-like sense of isolation from the outside world that's deeply satisfying. But it trips up on the details. The climate controls and many everyday functions are buried deep in a touchscreen menu system that can feel like navigating a bureaucracy. Child seat installation is also more fiddly than it should be at this price point.

Winner: Mercedes-Benz GLE 450e.

On the Road: BMW Pulls Ahead

This is where the two cars reveal their very different personalities, and if driving is something you actually care about, the BMW is something special.

The X5's hybrid powertrain is a force of nature. It rockets from 0 to 60mph in just 4.6 seconds, which is genuinely rapid for a large SUV. It feels planted and confident through corners, and there's a sense of precision and stability that makes you want to seek out a more interesting route home just to enjoy it a bit longer.

The GLE is no slowpoke either; it covers the same sprint in 5.7 seconds, which is perfectly brisk. Its hybrid system is smooth and refined, switching between electric and petrol power with barely a whisper. But the lighter steering that makes it so effortless around town starts to feel a little less assured at higher speeds, and it simply doesn't have the BMW's athletic edge.

Winner: BMW X5 xDrive50e.

Technology: Mercedes Pulls Back Ahead

Both cars come with sharp, fast-responding infotainment screens that look great and react instantly. The BMW's voice controls are genuinely impressive, some of the best in the industry, which helps compensate for those buried menus. But Mercedes has done something that BMW simply hasn't matched yet.

The GLE's optional augmented reality navigation overlays live camera footage from the front of the car with digital arrows and street names directly on the display, making turn-by-turn directions almost impossible to misread. It sounds like a gimmick until you use it in an unfamiliar city and realise you haven't taken a wrong turn once. It's the kind of feature that genuinely changes how you interact with the car.

Winner: Mercedes-Benz GLE 450e.

Value and Efficiency: Too Close to Call

Pricing is tight between the two. The GLE 450e starts at $73,600, while the BMW X5 xDrive50e opens at $77,450, a meaningful difference, though the BMW does come with slightly more standard equipment to justify it. Both cars carry a four-year, 50,000-mile bumper-to-bumper warranty, and both have the kind of fit and finish you'd expect from cars at this price.

BMW edges ahead with three years of complimentary maintenance included. But Mercedes hits back where it matters most for a plug-in hybrid — real-world efficiency. The GLE 450e manages an estimated 50 miles of pure electric range before the petrol engine kicks in, compared to 38 miles for the X5. Over weeks and months of daily commuting, that difference adds up to a meaningful amount of fuel saved.

Winner: a tie it genuinely depends on your priorities.

So Which One Should You Buy?

Here's the honest answer. If you love driving, if you relish a car that responds to your inputs, carries speed through corners with confidence, and makes you feel something on the way to work, the BMW X5 is the one. It's the most exciting machine in almost every driving scenario.

But if what you're really after is a supremely comfortable, beautifully finished, cleverly designed luxury SUV that happens to also be easy to live with every single day, and you want the better electric range to boot, the Mercedes GLE 450e is the stronger all-around package.

Both are excellent. But for most people, most of the time, the Mercedes wins.
