BMW is set to introduce an extended-range electric vehicle (EREV) powertrain option for its next-generation X5, reflecting the growing popularity of this drivetrain, particularly in the Chinese market. EREVs have surged in demand due to their ability to operate primarily on electric power for daily commuting, while providing reassurance against range anxiety and limited charging infrastructure on longer trips.
In collaboration with transmission specialist ZF, BMW aims to equip the new X5 large SUV with a range-extender system targeting a total driving range exceeding 965 kilometers (600 miles). This move aligns with the upcoming second-generation X7, which shares a platform with the X5 and is expected to offer a similar range-extender option on its flagship SUV.
Reports also suggest BMW is considering adding the range-extender powertrain to its current X3 mid-size SUV. All three models—the new X5, upcoming X7, and existing X3—are built on BMW’s CLAR architecture, which supports a variety of powertrains including mild-hybrid petrol and diesel, traditional plug-in hybrids, and fully electric drivetrains.
If confirmed, this will mark BMW’s first return to range-extender technology since discontinuing the i3 REx. The original i3 employed an electric motor powered by lithium-ion batteries for propulsion, while its range-extender variant featured a small 0.65-liter two-cylinder petrol engine generating 25 kW, paired with a 9-liter fuel tank. This engine activated only when the battery’s charge fell below a preset threshold, recharging the battery to extend driving range.
Details remain unclear regarding the specific engine type BMW will deploy for the X5’s range extender or whether this option will complement or replace the existing plug-in hybrid setup. Unlike conventional plug-in hybrids, where both electric motors and petrol engines can drive the wheels independently or together, EREVs rely primarily on electric drive with the petrol engine serving solely to recharge the battery.
Currently, Australia’s market features limited EREV options, including the Leapmotor C10 ‘REEV’ and Nissan’s X-Trail and Qashqai e-Power variants, while discontinued models like the i3 REx and Mazda MX-30 R-EV never gained traction. However, a wave of new EREV models is expected from automakers such as Ford, Mazda, BYD, Genesis, Ram, and Deepal, signaling a broader industry shift toward extended-range electric solutions.
