By Team Dailyrevs May 13, 2025
The 2025 Mansory Speranza is a one-off, four-door convertible SUV based on the Mercedes G-Class, featuring a fully electric soft top and rear-hinged rear doors.
-
Powered by a 4.0-liter twin-turbo V8 engine, it produces 820 hp and 1,150 Nm of torque, achieving 0–100 km/h in 4.0 seconds.

Extensive body reinforcements ensure structural integrity, while the interior offers bespoke customization with premium materials and finishes.
A G-Class, But Not As You Know It
The Mansory Speranza is one of those builds that forces a double-take. Based on a Mercedes G-Class, yes—but a roofless, four-door version with suicide doors at the back. It’s not just bold, it’s a full architectural rework of a very upright, very familiar shape.
From a distance, it still carries the boxy, slab-sided vibe we all know. But the proportions change the moment you notice the lack of a metal roof. The canvas top is fully electric, triple-layered, and reinforced for year-round usability. That’s not easy on a platform like the G-Wagen, which was never meant to be a convertible.
Mansory added triangular fixed glass panels behind the rear doors to keep some visual structure, and the doors themselves open rearward—just one of several design flourishes that separate this thing from its origins.
Reinforced and Ramped-Up
Taking the top off a G-Class isn't just a cosmetic decision. It required major reinforcement to the floor, frame, and sills to maintain structural integrity. It’s a critical detail, especially when you remember this is no mall crawler.
Under the hood sits a reworked 4.0-liter twin-turbo V8—familiar territory, but Mansory took it further. Bigger turbos, a new exhaust system, and reprogrammed engine control software push output to 820 hp and 1,150 Nm. That’s enough for a 0–100 km/h time of 4.0 seconds, which borders on absurd for something this blocky and luxurious.
Top speed? Electronically limited to 250 km/h. Because anything more in a topless G-Wagen might just be asking for trouble.
Inside: Custom Everything
Mansory doesn't skimp inside. The Speranza’s interior is decked out with quilted leather—on the seats, the dash, even the floor mats. Carbon fiber trim runs across the console and doors. Custom seat belts wear the Mansory logo, and the pedals are proper machined metal.
You also get a leather-wrapped and carbon-trimmed sports steering wheel, but thankfully it doesn’t try too hard to be sporty. This is still an SUV, just one with design cues more in line with a yacht than an off-roader.
Wheels That Match the Statement
It sits on massive 24-inch forged wheels—Mansory’s “FC.5” design—wrapped in 295/30R24 tires. They fill the arches cleanly and match the exaggerated, stance-heavy look. Overkill for a convertible SUV? Sure. But it works.
One-of-One, and That's the Point
The 2025 Mansory Speranza isn’t a production model. It's a one-off. Built not just to show off Mansory’s tuning and coachbuilding chops, but also to stretch the design language of the G-Class into a new space.
It’s weird, it’s wild, and it’s completely unapologetic—which, in this case, is exactly the idea.
