Show original supplier description
The BRABUS B63-620 Power Xtra is a performance enhancement kit specifically for the 2013-2018 G63 AMG models equipped with the M157 engine. This kit includes an auxiliary control module that integrates with the engine control unit to optimize performance. This power upgrade results in a significant increase in output, raising the rated horsepower from 400 kW (544 hp) to 456 kW (620 hp), an addition of 56 kW (76 hp). Peak torque is also enhanced, climbing from 760 Nm to 820 Nm (approximately 605 lb-ft). The kit's control unit is professionally calibrated for seamless integration with the standard engine management system. Performance gains include a reduction in acceleration time from 0-100 km/h for the G63 from 5.4 seconds to 5.1 seconds. Top speed can be optionally increased to 130 mph or 143 mph (210 km/h or 230 km/h), up from the stock 130 mph (210 km/h). It is important to note that all performance figures are approximate and can vary based on specific vehicle details, including weight, drivetrain, and aerodynamic components. The product comes with a 2-year warranty, a delivery time of 1-2 business days, and a 90-day return period. Please be aware that this part may be considered a Special Order, and potential additional costs for air freight, customs, taxes, and duties may apply.
