Mercedes-Benz GLE 400e vs BMW X5 xDrive50e: which premium plug-in hybrid D-segment SUV offers more in 2026

Choosing a premium plug-in hybrid mid-size SUV in 2026 is no longer just a question of brand. It is a question of numbers: how much power the combustion engine delivers with the electric motor’s support, how many real-world kilometres can be covered without burning a single drop of petrol and, above all, how much all of that costs. The Mercedes-Benz GLE 400e and the BMW X5 xDrive50e are, in our view, the two most complete representatives of this segment on the Spanish market right now. Both carry the CERO label, both hover around 110 km of homologated electric range and yet they are separated by almost 6,300 euros in RRP. Is paying more for the Bavarian worth it? Let’s look at the details.

Mercedes-Benz GLE 400e: the Mercedes-Benz mid-size SUV starting from ≈97,400 €

The GLE 400e uses a 2.0 M254 engine combined with an electric motor that together deliver around 380 hp (≈280 kW) and 650 Nm of torque. It is not the most powerful of the group, but its balance between consumption and responsiveness remains one of the strong points of the Mercedes-Benz range. The 0-100 km/h sprint takes about 6 seconds, a correct figure without reaching sporty territory, and the top speed sits around 210 km/h.

The indicative price starts at around 97,400 € RRP, excluding offers and dealer discounts, which makes it the most affordable entry point in this comparison.

BMW X5 xDrive50e: the BMW mid-size SUV starting from ≈103,700 €

BMW’s approach is different. The X5 xDrive50e combines a 3.0 six-cylinder with a more generous electric motor, reaching a combined output of approximately 490 hp (≈360 kW) and 700 Nm of torque. That is almost 110 hp more than the Mercedes-Benz, and it shows: the 0-100 km/h drops to about 4.8 seconds and the top speed climbs to 250 km/h. In our full BMW X5 xDrive50e review we already noted that this leap in performance is the central argument of the Bavarian proposal.

The starting price is around 103,700 € RRP, again as an indicative reference without promotions.

Power and performance: the clearest gap in the comparison

Here there is no contest. The BMW X5 xDrive50e delivers around 110 hp more than the Mercedes-Benz GLE 400e and shaves a full second off the 0-100 km/h. On paper, it is the more forceful of the two PHEV mid-size SUVs. In practice, driving both on open roads, that difference translates into a sense of power reserve the GLE does not entirely match, especially when overtaking at high speed. That said, the Mercedes-Benz does not fall short for the real-world use of a family SUV: 380 hp is still more than enough for everyday driving.

Electric range and homologated consumption: technical tie

Both declare an electric range of around 110 km, practically identical, which levels the field on the aspect that matters most to buyers of a PHEV who want to get around daily without the combustion engine. The combined homologated consumption slightly favours the BMW (≈1 l/100 km versus the Mercedes-Benz’s ≈3 l/100 km), although this should be qualified: these figures depend heavily on the homologation cycle and, in real use, tend to converge far more than the paper suggests.

Price, CERO label and purchase incentives

Both models carry the DGT CERO label, which in practice means unrestricted access to low-emission zones and tax advantages in several autonomous communities. The price difference —about 6,300 € in favour of the Mercedes-Benz GLE 400e— is significant in this segment, and it is worth remembering that anyone opting for either car can check the current conditions of the Plan Auto+ to see whether any purchase incentive applies, always reviewing the official programme website before closing the deal.

Summary comparison table

Verdict: which is the better premium plug-in hybrid SUV of the two?

If the criterion is pure performance, the BMW X5 xDrive50e wins clearly: more power, more torque, higher top speed. If the criterion is a tight budget without giving up equivalent electric range, the Mercedes-Benz GLE 400e more than meets the need and leaves almost 6,300 € in your pocket. There is no single answer —it depends on how much each buyer values those extra hp— although for mixed city-and-motorway use, the GLE strikes us as the option with the best balance between cost and what it offers. For anyone who has already decided to compare other proposals in the segment, our review of the Volvo XC90 versus the Mercedes-Benz GLE adds another useful perspective.
