Final stretch: the new BMW X5 enters its final test phase ahead of production

BMW has entered the final calibration phase for the fifth-generation X5 ahead of its market launch, with final test drives now underway at the BMW Group Plant Spartanburg in the USA. The new X5 marks the first BMW model to be offered with a choice of five distinct drive systems, including the debut of the fully electric BMW iX5, a plug-in hybrid X5 50e xDrive, mild-hybrid petrol and diesel variants, and the upcoming hydrogen-powered BMW iX5 Hydrogen slated for 2028. During pre-production evaluations, journalists sampled three key variants: the X5 40 xDrive (294 kW/400 HP), X5 50e xDrive plug-in hybrid (360 kW/490 HP), and the iX5 60 xDrive (425 kW/578 HP). The fully electric iX5 leads with sixth-generation BMW eDrive tech, featuring an 800V architecture and a new high-voltage battery using cylindrical cells. The battery offers 144 kWh usable energy in the USA and 141 kWh in the EU (net), making it the largest high-voltage battery ever fitted to a production BMW EV. Power delivery comes via dual electric motors—one at each axle—paired with xDrive electric all-wheel drive. The hydrogen-powered iX5 Hydrogen, due in 2028, introduces BMW’s third-generation fuel cell system and a Flat Storage tank layout using seven carbon-fiber high-pressure tanks integrated into a metal frame. This design maximizes cabin space while enabling shared production with other X5 variants. Driving dynamics are elevated by the new “Heart of Joy” system, derived from BMW’s Neue Klasse architecture. This in-house-developed control stack operates ten times faster than previous systems, synchronizing powertrain, brakes, steering, charging, and recuperation in milliseconds for razor-sharp agility and precision. In the iX5 and iX5 Hydrogen, it enhances smoothness during stops and boosts regenerative braking efficiency. For combustion and plug-in models, the X5 features a tenth-generation transverse dynamics management system, near-actuator wheel slip limitation, and a precisely tuned chassis with adaptive suspension and near 50:50 weight distribution. Optional Adaptive Chassis Control Professional adds two-axle air suspension, electronically controlled dampers, Integral Active Steering, and active roll stabilization for the iX5 and plug-in variants. The X5 also debuts next-generation SAE Level 2 driver assistance systems, further enhancing safety and convenience.
