BRABUS turns the current Mercedes-AMG G 63 into a 700-hp machine with the PowerXtra B40-700. Official book for the W465 G 63: 515 kW / 700 hp and 950 Nm, up from the stock 430 kW / 585 hp and 850 Nm. That is +85 kW / +115 hp. Plug-and-play auxiliary ECU. Bottrop installation. The kit price on the BRABUS shop sits around €9,000–€9,225 VAT-included depending on market — kit only, not a complete G-Wagen MSRP.
700 is the power kit. WIDESTAR is the body kit.
When people say “BRABUS 700” on a G-Wagen, they usually mean the full look: PowerXtra B40-700 under the hood, WIDESTAR widebody outboard, and big Monoblocks filling the arches. BRABUS sells those as separate lines on the W465 AMG G 63 tuning overview.
PowerXtra B40-700 is the performance package: a processor-driven auxiliary control module adapted plug & play to the stock engine management. WIDESTAR is the body kit. On the same overview page, BRABUS WIDESTAR lists from about €29,880 VAT included. Carbon WIDESTAR starts from about €54,000 VAT included. Wheels, exhaust, carbon bits, and Adventure hardware stack on top. The number on the fender badge is the power stage. The stance is WIDESTAR.
Stock G 63 vs BRABUS PowerXtra B40-700
Figures below are from BRABUS’s current W465 B40-700 product page. BRABUS labels the acceleration and top-speed numbers as approximate and vehicle-specific.
| Stock AMG G 63 | BRABUS B40-700 | |
|---|---|---|
| Power | 430 kW / 585 hp | 515 kW / 700 hp |
| Torque | 850 Nm | 950 Nm |
| 0–100 km/h | 4.5 s | 4.3 s |
| Top speed | 220 km/h (137 mph) | Optionally 220 or 240 km/h (137 or 149 mph) |
Same story on the prior-gen W463A G 63 page: same 700 hp / 950 Nm step, same 4.3 s claim, same optional Vmax. Higher BRABUS stages exist on the W465 board — including PowerXtra B40S-800 from about €29,880 VAT included — but this post is the 700.
No factory clutch on the G 63 — or the BRABUS 700
This is the clutch graf, and the official book is clear by omission. The stock Mercedes-AMG G 63 is an automatic — AMG SPEEDSHIFT / 9G-Tronic family — with no three-pedal path from the factory. BRABUS does not add a manual gearbox with the PowerXtra B40-700. What BRABUS does sell on the same W465 G 63 overview is optional hardware around that automatic, including carbon paddle shifters on the shop list. Paddle cosmetics, not a clutch pedal.
Shop price for the kit — not the whole truck
On the Austrian BRABUS shop, PowerXtra B40-700 for the W465 G 63 shows €9,000 VAT included for the kit (schema/list), with a configured Gesamtpreis around €10,068 once selected options land in the cart. The Ireland shop lists the related W463A B40-700 around €9,225 VAT included. Treat those as BRABUS shop prices for the PowerXtra kit alone. They are not a complete G-Wagen MSRP, and they are not the sticker for a full BRABUS 700 WIDESTAR build with body, wheels, and exhaust.
Delivery and assembly on the product page point to installation at BRABUS in Bottrop. The item can show as requestable depending on market and cart state. BRABUS will contact you to schedule the job.
