Powertrain & Engine Architecture
The iX xDrive40 utilizes a dual-motor, all-wheel-drive (AWD) powertrain. Each axle features an electric motor, providing instant torque and precise control. The front motor produces 272 horsepower, while the rear motor generates 340 horsepower, combining for a total system output of 326 horsepower and 630 Nm (464.66 lb.-ft.) of torque. The powertrain operates at a high voltage of 330.3V, utilizing a lithium-ion battery pack with a gross capacity of 76.6 kWh and a usable capacity of 71 kWh. The battery is positioned low in the vehicle floor, contributing to a lower center of gravity and improved handling. The single-speed automatic transmission is inherent to electric vehicle design, providing seamless acceleration. The electric motors employ advanced cooling systems to maintain optimal operating temperatures during demanding conditions.
