Brabus 800 Adventure XLP — Complete Guide 2026 | Specs & Configuration

The Brabus 800 Adventure XLP is one of the most extreme street-legal vehicles Brabus has ever produced — a pickup-truck conversion of the Mercedes-AMG G63 W463a with a fully retained rear seat, an open cargo bed behind the B-pillar, and an 800hp powertrain developed entirely in-house at Bottrop. Only around 50 to 100 examples are expected to exist worldwide across the entire production run, making the Adventure XLP one of the rarest G-Wagen derivatives ever built. This complete guide covers the real Brabus specification — drivetrain, portal axles, widebody fenders, brakes, wheels, interior — plus a future-proof ownership strategy for 2030 and beyond.

Adventure XLP — Key Specifications

Platform & Conversion Overview

The Adventure XLP is built on the current Mercedes-AMG G63 (W463a, 2018–present) — the heavily re-engineered G-Wagen that retains the body-on-frame construction and three locking differentials of the original but pairs them with independent front suspension, a modern 9G-TRONIC gearbox and the 4.0-litre M177 biturbo V8. Brabus takes a donor G63 and cuts the body behind the B-pillar, extending the chassis and fitting a reinforced open cargo bed while keeping the full rear seat intact. The result is a four-seat pickup with a proper load area — closer in concept to the legendary G500 4×4² pickup versions of the past than to any production Mercedes. Unlike the wider 6×6 or G800 programs, the XLP is a 4×4 truck, which makes it narrower in the lane and dramatically more usable day-to-day.

Brabus 800 Power Xtra Engine

The 800hp figure comes from Brabus's 800 Power Xtra package, which replaces the factory 4.0-litre M177's turbochargers with larger Brabus-spec units, reworks the induction plumbing, fits a dedicated Brabus ECU with re-mapped ignition, fuelling and boost pressure, and finishes with a stainless-steel Brabus exhaust featuring active valve control and dual twin tailpipes integrated into the new rear bumper. Power rises from the factory 585hp to a full 800hp at 6600 rpm; torque is held at 1000 Nm by Brabus's own limiter to protect the 9G-TRONIC gearbox. Despite the added body mass and raised ride height of the XLP, Brabus claims a 0–100 km/h time in the high 4-second range — outrageous for a vehicle of this size, weight and aerodynamic profile.

Widebody, RAM-Bar & Exterior

The Adventure XLP's visual signature is unmistakable: full Brabus widebody fenders front and rear that add 20 cm to the overall width, an aggressive front RAM-bar replacing the factory bumper, a reshaped bonnet with functional ventilation, re-styled side skirts that bridge the gap between the cabin and cargo bed, and a bespoke rear bumper with integrated twin-tailpipe outlets and reinforced loading lip. Carbon-fibre is used throughout — on the RAM-bar leading edges, on the mirror caps, on the door handles, and on the widebody arch flares. Roof-mounted LED light bars, auxiliary spotlights and a roof rack optimised for jerrycans and recovery gear are standard on the Adventure specification. The entire kit is engineered to be TÜV-approved in Germany despite the radical body modifications.

Wheels — 22" Monoblock M Platinum or 24" PORTAL

Two wheel configurations define the Adventure XLP. The standard specification fits the 22" Brabus Monoblock M Platinum Edition forged wheel — a lightweight multi-spoke monoblock in 10.0J × 22 with ET36 offset, wrapped in Pirelli Scorpion All-Terrain Plus tyres in 295/40 ZR22. The Platinum surface treatment uses a PVD coating that resists corrosion from rock chips and salt spray far better than conventional paint. For customers who want the most extreme Adventure specification, Brabus offers a full PORTAL axle conversion: the factory independent front axle is replaced with a Brabus-engineered solid portal axle assembly that routes the drive through reduction gears mounted inboard of the wheel hub, raising the entire chassis by an additional 190 mm on top of the XLP's standard lift — and requiring 24" forged wheels with matching 325-series all-terrain rubber. The PORTAL option is predominantly ordered in markets where dune-running and serious off-road use are part of the ownership profile.

Brabus Brakes & Suspension

The Adventure XLP uses Brabus's own high-performance brake system, which mates a 6-piston fixed aluminium front caliper to a drilled and vented disc in Platinum coating, with a single-piston floating rear caliper for controllability under trail-braking and off-road descents. The pad and disc compound is selected to resist both high-speed stopping fade and low-speed dust build-up from unpaved-road use. Suspension is the Brabus +ATX off-road setup: uprated coil springs, re-valved dampers matched to the additional lift, and a ride-height increase of 200 mm. That geometry change significantly improves approach, break-over and departure angles — important given the extended wheelbase of the pickup conversion. The XLP retains all three factory locking differentials (front, centre, rear) and full low-range, so its off-road capability is effectively uncompromised despite the performance upgrades.

Interior — Brabus Mastik Leather

Inside, the Adventure XLP is trimmed end-to-end in Brabus's Mastik fine-grain leather in a customer-specified colour combination, with contrast stitching, Brabus logos embroidered into the headrests, and carbon-fibre or fine-wood inlays on the dashboard, centre console and door cards. The rear cabin retains the full G63 rear bench, so the vehicle remains a four-seat vehicle despite the cargo bed conversion. Bespoke Brabus floor mats, Brabus illuminated door sills and a numbered dashboard plaque identifying the build are standard.

Adventure XLP in 2030 — Future-Proof Investment Modifications

With only around 50 to 100 Adventure XLPs expected to ever exist, this vehicle is a near-certainty to become a Singer-style collector grail within the next five to seven years. Our 2030 future-proof strategy for XLP owners is deliberately conservative: keep the vehicle as originally delivered and treat every document, component and surface as provenance-critical. Do not modify further — the XLP is already a one-of-one on arrival; additional aftermarket work (non-Brabus wheels, re-wraps, performance add-ons from third parties) reliably destroys resale. Keep the original VIN paperwork, the Brabus build sheet and every factory specification photograph in a fireproof safe; request the Brabus Classic Center's registration record for your build if the program becomes available to your chassis number. Apply full-body paint protection film on the launch day before the car is ever driven on a public road, and budget for PPF refresh every five years. Store the vehicle in a climate-controlled facility kept between 15 and 22 °C at 50% relative humidity to preserve the Mastik leather and prevent micro-corrosion on the chromed components. Track the ownership chain rigorously — a single missing owner in the logbook can remove five figures from future resale. Service only through Brabus-authorised workshops so every service entry bears the correct stamp, and retain every invoice for parts and labour. Our forecast: a correctly preserved Adventure XLP will outperform comparable hypercars as a long-horizon asset, with the combination of build-count rarity, pickup-truck novelty and the looming end of the W463a V8 era driving demand from 2028 onward as new G-Wagens transition to hybrid and EV powertrains.

Frequently Asked Questions

How many Brabus 800 Adventure XLPs will be built?

Brabus has not announced a fixed production cap, but industry estimates based on build slots, reveal cadence and parts lead-times put the realistic worldwide total at roughly 50 to 100 vehicles across the entire W463a generation. Each build is made to order in Bottrop, with wait times typically running six to nine months from contract signature to delivery. Because every car is specified individually to the customer's colour, leather, trim and wheel preference, there are effectively no two identical XLPs — each is a one-of-one.

Is the cargo bed actually usable?

Yes. The XLP's bed is a fully load-rated open cargo area with a reinforced floor, tie-down anchors and a tailgate, capable of carrying jerrycans, luggage, recovery kit or motorcycle gear. It's not as long as a proper mid-size pickup's bed, but it's genuinely functional. Many owners specify bed-mounted aluminium storage boxes or full tonneau covers from the Brabus catalogue. The rear seat remains fully habitable, so you retain the four-seat cabin of a G-Wagen even with a loaded bed behind it.

PORTAL axles or 22" Monoblock — which should I choose?

If your XLP will live on paved roads with occasional gravel use, the 22" Monoblock M Platinum configuration is the correct choice: it keeps ride quality civilised, preserves on-road acceleration, and gives the XLP its cleanest visual proportions. If the car will be used seriously off-road — dune running in the Gulf, expedition work in Africa, overlanding in Baja — the 24" PORTAL conversion is transformative: the extra 190 mm of clearance on top of the +ATX lift opens up terrain that no unmodified G63 can access. The PORTAL option roughly doubles the exterior visual drama but dulls on-road handling noticeably; plan accordingly.

Does the 800hp Power Xtra upgrade affect the warranty?

The Brabus 800 Power Xtra package carries Brabus's own factory warranty covering the modified engine and drivetrain components for the duration and distance specified in the build contract — typically matching the balance of the Mercedes-Benz factory warranty or running for two years from Brabus delivery, whichever is longer. Any Mercedes-Benz powertrain warranty implications depend on local regulations; in the EU, consumer protection law generally protects non-modified components, while in the US the situation varies state to state.
