An Unusual BMW and Mercedes Encounter

Prototype testing usually happens away from public attention, but occasionally two future vehicles from different manufacturers end up in the same frame. That is exactly what happened in Munich, Germany, where prototypes believed to be the next-generation BMW X5 M and the smaller Mercedes-Benz G-Class were spotted together.

Both vehicles were heavily camouflaged and reportedly photographed while stopped at a traffic light. The unexpected side-by-side comparison immediately highlighted one obvious difference: the BMW appears substantially larger than the upcoming compact G-Class.

The unusual encounter also provides a useful glimpse at how differently BMW and Mercedes-Benz are approaching the performance and luxury SUV markets.

The BMW X5 M Looks Massive Beside the Baby G-Class

The most noticeable detail in the photographs is the difference in overall size. The next BMW X5 M has the proportions of a large premium SUV, while the new smaller G-Class is expected to sit below the traditional G-Wagon in Mercedes-Benz’s lineup.

The comparison is especially interesting because both vehicles are designed to deliver a premium SUV experience, but their identities are very different. The X5 emphasizes road performance, technology and high-speed capability, while the G-Class is known for its upright shape and strong connection to traditional off-road design.

What Could Change on the 2027 BMW X5 M?

The next-generation BMW X5 M is expected to receive a much more aggressive front-end design. Early indications point toward a redesigned kidney grille with a more upright and three-dimensional appearance.

The front bumper also appears to be receiving larger air openings and additional ventilation areas. These changes would give the performance SUV a more muscular appearance while potentially supporting the cooling requirements of its high-performance powertrain.

Because the prototype remains covered in camouflage, many of the final exterior details are still difficult to determine. BMW is expected to reveal more as development moves closer to production.

Could the Next X5 M Use Four Electric Motors?

One of the most interesting reports surrounding the next BMW X5 M is its possible move toward an all-electric performance powertrain.

Current reports suggest that the high-performance SUV could potentially use four electric motors, with one motor driving each wheel. If this configuration reaches production, it could provide extremely precise control over torque distribution and vehicle dynamics.

An estimated output in the region of 800 to 900 horsepower has also been suggested. These figures remain unconfirmed, however, and should be treated as expectations rather than official BMW specifications.

Mercedes-Benz Is Preparing a Smaller G-Class

Parked alongside the BMW was a prototype of Mercedes-Benz’s upcoming smaller G-Class. Despite its reduced dimensions, the vehicle appears to retain the boxy silhouette that has made the G-Class instantly recognizable.

The prototype reportedly features a rear-mounted spare wheel, distinctive alloy wheels, LED rear lighting and a high-mounted brake light. These details suggest that Mercedes-Benz wants the smaller model to maintain a clear visual connection with the larger G-Class.

Rather than creating a completely different-looking compact SUV, Mercedes appears to be carrying the familiar G-Class design language into a smaller package.

An Electric Version Is Expected

The smaller G-Class is expected to be offered with an all-electric powertrain. Reports indicate that the electric version could use an approximately 85 kWh battery pack combined with dual electric motors.

A projected driving range of up to around 450 miles has also been reported. As with the X5 M specifications, these figures should be considered preliminary until Mercedes-Benz officially confirms the production vehicle.

Two Very Different Approaches to the Luxury SUV

The side-by-side sighting highlights an interesting contrast between the two manufacturers. BMW’s X5 M is expected to focus heavily on road-going performance, advanced chassis technology and enormous power.

Mercedes-Benz’s smaller G-Class, meanwhile, appears to be concentrating on design heritage and accessibility. Its upright body and familiar styling are intended to make it immediately recognizable as a member of the G-Class family.

If both vehicles eventually adopt high-output electric powertrains, they could also demonstrate two very different interpretations of the future performance SUV.

Why These Prototypes Matter

The automotive industry is moving rapidly toward electrification, and premium manufacturers are experimenting with new ways to deliver performance using electric power.

A potential 800-to-900-horsepower electric X5 M would represent a major step for BMW’s M division, while an electric compact G-Class would bring Mercedes-Benz’s iconic design into a smaller and potentially more accessible segment.

Neither vehicle is production-ready yet, but these road tests show that both manufacturers are actively developing their next-generation SUV strategies.

Final Thoughts

Seeing the next BMW X5 M and smaller Mercedes-Benz G-Class together provides a fascinating look at the future of premium SUVs. The enormous size difference is immediately noticeable, but the more important story is what lies underneath the camouflage.

BMW is reportedly exploring an electric X5 M with potentially four motors and close to 900 horsepower, while Mercedes-Benz is preparing a smaller G-Class with an expected electric variant and a long-range battery system.

For now, many of the technical details remain unconfirmed. More prototypes, testing footage and eventually official announcements should reveal exactly how these two German SUVs will evolve.
