Show original supplier description
The Brabus PowerXtra B40-700 tuning kit is engineered to elevate your vehicle's performance by upgrading the engine's control unit with a proprietary processor auxiliary control module. The kit delivers an impressive performance increase of up to 85 kW (115 hp) and 100 Nm, bringing the total output to 515 kW (700 hp) with a substantial peak torque of 950 Nm. This enhancement allows for a rapid 0-100 km/h acceleration time of just 4.3 seconds, down from the stock 4.5 seconds. Buyers can also choose their preferred top speed configuration: either 137 mph (220 km/h) or 149 mph (240 km/h). Compatibility is specific to the Mercedes-Benz G-Class W463A and W464, in conjunction with G63 AMG models, for the years 2018-2024. While the installation process is described as Plug & Play, Brabus strongly recommends professional installation at a specialized workshop to ensure optimal performance and integration. For customers unsure about compatibility or installation, providing a VIN (vehicle identification number) during the order process can help verify fitment. It is the owner's responsibility to check and comply with local road and traffic regulations, as registration may be required in certain regions. The retrofit kit includes the single BRABUS control module along with all necessary mounting elements. All performance indicators provided are approximate values and can be influenced by various factors including ambient temperature, humidity, vehicle weight and configuration, installed equipment, wheel size, transmission, and aerodynamic packages. Stock values are provided for comparison.
