BMW was a pioneer within the EV section with range-extending engines. The i3 REX debuted over a decade in the past, that includes an optionally available two-cylinder engine. Borrowed from the Motorrad division, the compact 647-cc fuel engine was tailored to function a generator to recharge the battery. It was a one-off resolution, because the packaging was by no means replicated in one other mannequin.
Nevertheless, a brand new report from Autocar means that the range-extending engine might make a comeback. The British publication cites sources accustomed to BMW’s plans, pointing to a brand new system co-developed with provider ZF. The know-how is reportedly meant for SUVs and will debut within the next-generation X5 (pictured right here), codenamed “G65.”
The tech can also be used within the next-generation X7, the “G67.” The three-row SUV is scheduled to launch within the second half of 2027. Even the present X3, identified internally as “G45,” is believed to be a candidate for REX remedy, though that is unlikely to occur till its mid-cycle facelift. The LCI is predicted to reach in late 2028.
The brand new range-extending fuel engine would run solely at its optimum rpm to maximise effectivity. It might be paired with BMW’s next-generation batteries, particularly contemplating the all-electric iX5 will use the Gen6 pack debuting within the Neue Klasse iX3 later this yr. These cylindrical cells will supply 20% larger power density and a 30% enhance in vary in comparison with at present’s prismatic batteries. Mixed with the REX, this could just about get rid of vary anxiousness, even in massive SUVs just like the X5 and X7.
The X5 is shaping as much as have an exceptionally various powertrain lineup: gasoline, diesel, plug-in hybrid, battery electrical, hydrogen gasoline cell, and now this rumored range-extender pairing a fuel engine with batteries. BMW is unlikely to supply all variations globally; as an alternative, it can tailor availability based mostly on regional demand.
For instance, vary extenders are gaining recognition in China. Volkswagen’s revived Scout model will introduce the know-how within the U.S. on the upcoming Terra pickup and Harvester SUV. VW’s core model additionally plans to launch range-extending EVs in China and doubtlessly different areas. Its upcoming Scalable Techniques Platform (SSP) will assist EVs outfitted with a combustion engine that acts as a generator.
It stays unclear how a lot an X5 with a spread extender would value, although it’s prone to be priced between the plug-in hybrid and the absolutely electrical iX5.
