The next-generation BMW X5 raises the bar in several areas, but none more so than in fully electric form. The new BMW iX5 combines a huge 141 kWh battery with ultra-fast charging of up to 460 kW, producing figures that immediately catch the eye. Yet the real achievement lies elsewhere. BMW’s engineers were determined that the latest X5 should be judged not only by its technical specifications, but by how convincingly it drives.
To find out, we sampled both the electric iX5 60 xDrive and the petrol-powered X5 40 xDrive during extensive prototype testing across the roads of the American South. Compared with the outgoing G05 generation — previously available with petrol, diesel and plug-in hybrid powertrains — the improvements are substantial, particularly where ride comfort is concerned.
The new G65-generation X5 benefits from larger wheel options, revised suspension geometry and, crucially, an optional air suspension system that is paired with rear-wheel steering in most markets. It is an option well worth choosing, especially on combustion-powered models where it is not fitted as standard, unlike several plug-in hybrid variants.
BMW’s decision to offer five different powertrain concepts within a single model line is technically fascinating, although most buyers are unlikely to pay much attention to the hydrogen-powered version scheduled to arrive from 2028. The electric iX5, by contrast, should prove far more significant, particularly in Europe.
Initially offered exclusively as the iX5 60 xDrive, the electric flagship combines dual motors, all-wheel drive, 578 PS and an 800-volt electrical architecture. Even customers traditionally loyal to combustion engines may find themselves reconsidering once they see the numbers. The enormous 141 kWh battery, combined with charging speeds of up to 460 kW, promises genuine long-distance capability with minimal charging stops. Starting at €102,800, the iX5 is also priced alongside the 612 PS plug-in hybrid rather than above it.
As Joachim Post explains: “With its impressive presence and perfect blend of comfort and driving pleasure, the BMW X5 has become a global bestseller. The latest generation now benefits from Neue Klasse technologies and the widest drivetrain choice we’ve ever offered.”
With such a large battery pack — featuring BMW’s new 120 mm cylindrical cells — alongside a generous collection of luxury and safety equipment, the iX5 inevitably tips the scales at almost 2.9 tonnes.
Remarkably, very little of that weight is apparent from behind the wheel.
Even on twisting country roads, the networked chassis disguises the mass with impressive effectiveness. Regardless of which driving mode is selected, the underlying character remains consistent. The low centre of gravity, naturally weighted steering and seamless blending between regenerative and friction braking create an exceptionally polished driving experience, even in prototype form.
Body roll and pitch are kept to an impressive minimum thanks to the active roll stabilisation system, initially available only on the electric and plug-in hybrid models. Despite its considerable weight, the iX5 delivers immense performance through its 805 Nm of torque, providing effortless acceleration that makes even BMW’s former quad-turbo diesel flagship feel like a distant memory.
Thankfully, BMW also allows drivers to disable the synthetic soundscape generated through the premium audio system. Silence suits the electric X5 far better than futuristic spaceship effects.
Around Greenville, South Carolina, the iX5 feels noticeably smaller than its dimensions suggest. The steering is direct yet light enough for urban driving, while revised suspension mounting points contribute to impressive agility through junctions and tighter corners. Ride comfort remains excellent even over broken road surfaces despite the optional 22-inch wheels. Buyers will be able to choose between 21-, 22- and 23-inch wheel designs, though the middle option strikes the most convincing balance between comfort and appearance.
Depending on driving style, equipment specification and wheel choice, BMW expects real-world driving range to comfortably exceed 800 kilometres. One disappointment remains: top speed is electronically limited to 210 km/h, a restriction that may deter some buyers, particularly in Germany.
The petrol-powered X5 40 xDrive tells a slightly different story.
Powered by a 400 PS turbocharged inline-six, it weighs around 600 kilograms less than its electric sibling. Unsurprisingly, it feels lighter and marginally more agile, while its steering offers slightly greater resistance and more natural feedback. Although the engine note lacks much emotional appeal, the overall package remains hugely convincing and will likely continue to attract many traditional BMW customers.
The braking performance is virtually indistinguishable from the electric version, while the ride remains supple and composed.
Inside, BMW’s minimalist Neue Klasse-inspired cabin divides opinion. Material quality is excellent, but the absence of a conventional instrument binnacle behind the unusual four-spoke steering wheel requires an adjustment period for long-time BMW owners. Equally unconventional are the new hidden door releases, replaced by slim wings integrated into the window line. Buyers can even specify electrically powered doors, adding yet another layer of luxury before the journey has even begun.
Fortunately, once underway, the new X5 delivers exactly what matters most. Whether powered by petrol or electricity, BMW has produced its most refined and comfortable X5 yet — without sacrificing the dynamic character that has always defined the model.
