Mansory Gronos 6x6

When a vehicle can do more than its system knows.

Mansory is one of the world's most exclusive customizers of luxury and high-performance vehicles. For the Gronos 6x6, a standard Mercedes-Benz G 63 AMG undergoes a fundamental transformation: conversion to three axles with portal gear, performance upgrade to 900 hp and 1,200 Nm, plus retrofitted off-road systems including a tire pressure regulation system with high-performance compressor, a cable winch and four LED auxiliary headlights mounted on the roof. A vehicle built for maximum off-road mobility - for clients investing six-figure sums.

The problem: the G 63's stock control system doesn't recognize these retrofitted functions. There was no interface to adjust tire pressure across all six wheels while driving, activate the winch or control the auxiliary lighting. Mansory needed a solution that communicates reliably with the ECU while delivering a user experience worthy of a vehicle in this class.

Off-the-shelf solutions didn't exist for this requirement. Mansory needed a bespoke development - software, hardware integration and interface design from a single source.

An interface as exclusive as the vehicle itself.

We developed a fully bespoke control application for Mansory that runs on a mini PC inside the vehicle and is operated via a touchscreen mounted above the rearview mirror.

The application is built on Node.js and communicates directly with the Gronos 6x6's ECU. Through a central interface, the driver controls all retrofitted systems: the tire pressure regulation system adjusts pressure across all six wheels in real time to match terrain conditions – without leaving the vehicle. Winch, auxiliary lighting and additional components are activated and controlled through the same interface.

We designed the UI specifically for the cockpit environment: high contrast, generous touch targets and a visual language that integrates seamlessly into the interior of a Mansory vehicle. Not a generic dashboard - but an interface that reflects the standard of quality Mansory clients expect from every detail.

For Mansory, this means: an invisible yet indispensable technology layer that makes the Gronos 6x6 one of the most exclusive off-road vehicles in the world - not just visually, but functionally.
