BMW is gearing up for significant updates to its flagship X5 crossover, which will not only feature traditional internal combustion engines but also an all-electric version known as the iX5, as well as a hydrogen fuel cell modification planned for release in 2028. Prototypes of the X5 and iX5 have been sighted with a fresh design inspired by the Neue Klasse concept, with the new X5 generation utilizing the upgraded BMW CLAR architecture. This platform offers versatility in powertrain choices, accommodating gasoline, diesel, hybrid, electric, and hydrogen options. The iX5 will boast BMW's latest sixth-generation electric motors, an 800-volt architecture, and new battery cells with improved energy density. For consumers seeking an alternative to the internal combustion engine or electric car, BMW will introduce a hydrogen fuel cell version with a drive system co-developed with Toyota, promising superior performance compared to the iX5 Hydrogen prototype. Alongside the electric and hydrogen variants, the X5 lineup will retain 48-volt mild hybrids based on 3.0-liter inline six-cylinder turbocharged gasoline and diesel engines, including the high-performance X5 M60 model. In Europe, an updated 3.0-liter plug-in hybrid unit will be available, while the US market will offer a 4.4-liter V8 with twin turbines. Furthermore, an iX5 M Performance model is in the works, expected to deliver over 600 hp. BMW's forthcoming X5 family refresh underscores the brand's commitment to eco-friendly technologies, with electric and hydrogen models playing a pivotal role in this sustainable transition.
