Mansory’s Bonkers convertible G-Wagen makes 820 HP and ditches the roof

The Mansory Speranza, unveiled in Monaco on May 8, 2025, is a convertible version of the Mercedes-Benz G-Class, something rarely seen in the auto world. But this isn’t just a topless G-Wagen. It’s a ground-up reengineering feat, with Mansory reinforcing the chassis to maintain structural integrity after removing the load-bearing roof.

Powering the Speranza is a heavily tuned 4.0-litre V8 engine, producing 820 horsepower and propelling the vehicle from 0 to 62 mph in just four seconds. Its top speed is electronically capped at 155 mph. The bold four-door design includes rear-hinged suicide doors, adding to the eccentric personality of a vehicle destined to turn heads anywhere it roams.

Inside, Mansory offers full customization. Each model is a bespoke creation, tailored to individual client preferences. Expect quilted leather floor mats, carbon-fiber pedals, custom-branded seatbelts, and a sculpted steering wheel with Mansory’s signature styling.

Though pricing remains undisclosed, industry experts estimate it will likely surpass $1 million, firmly placing the Speranza in the ultra-exclusive club of “one-of-one” automotive creations.
