BMW X5 long-wheelbase for China: 130 mm stretch, 8K cinema screen, 1,000 km EV range

Full text

The long-wheelbase versions of the X5 and iX5 use self-driving tech from Momenta.

BMW partnered with Momenta in mid-2025 to power its local self-driving systems.

One of the iX5’s all-electric versions will have a driving range of over 621 miles.

Less than a month after the all-new BMW X5 premiered, long-wheelbase versions of it and the electric iX5 have arrived in China, and beyond the added length you would struggle to spot anything separating them from the X5s headed to Western markets.

The stretch comes from reworked underpinnings, giving the Chinese models a wheelbase 5.1 inches (130 mm) longer and pushing the gap between the axles to 124.6 inches (3,165 mm). To put that into perspective, the larger X7 sold globally measures 122.2 inches (3,105 mm) between its wheels, so anyone who plans to spend more time in the back seat than behind the wheel might find this X5 the smarter buy.

When BMW rolled out the domestic long-wheelbase versions of the new i3 and iX3 earlier this year, it dropped the pop-out door handles used on those models globally, switching to flap-style handles to satisfy Chinese regulations. The X5 L and iX5 L needed no such fix, keeping the handle tabs built into the pillars, an approach shared with the Ford Mustang Mach-E.

Chinese Autonomy

Perhaps the biggest change related to the driver-assistance systems. It runs software from Chinese company Momenta, using locally trained end-to-end artificial intelligence and providing ‘address-to-address driver assistance.’ While it does not include a LiDAR, as many new cars from China do, it’s likely to be more advanced than the system BMW offers elsewhere.

One minor visual change made to the SUV is the presence of distinctive graphics near the Hofmeister kink and different wheel designs. As standard, the X5 L and iX5 L also feature diagonal daytime running lights, rather than the X-shaped lights of their global model. However, these units will be offered as an option. BMW’s Chinese team has also added extra light strips between the DRLs and the kidney grilles. The front bumper is also slightly less imposing.

Interior Upgrades

Several changes have been made to the cabin, making the long-wheelbase model even more luxurious than the standard model. These include new seats for the front passenger and rear occupants, and a fold-down theatre screen in the second row that supports 8K streaming and gaming. There are also different color options.

BMW has yet to publish powertrain figures for either car, but the company says the local iX5 L will cover more than 621 miles (1,000 km) between charges on the CLTC cycle.
