BMW was a pioneer within the EV phase with range-extending engines. The i3 REX debuted over a decade in the past, that includes an non-compulsory two-cylinder engine. Borrowed from the Motorrad division, the compact 647-cc gasoline engine was tailored to function a generator to recharge the battery. It was a one-off answer, 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 may 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 may additionally be used within the next-generation X7the “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 therapy, though that is unlikely to occur till its mid-cycle facelift. The LCI is anticipated to reach in late 2028.
The brand new range-extending gasoline 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 12 months. These cylindrical cells will provide 20% larger vitality density and a 30% improve in vary in comparison with right now’s prismatic batteries. Mixed with the REX, this could just about get rid of vary nervousness, even in giant 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 gas cell, and now this rumored range-extender pairing a gasoline engine with batteries. BMW is unlikely to supply all variations globally; as a substitute, it can tailor availability primarily based 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 probably different areas. Its upcoming Scalable Techniques Platform (SSP) will assist EVs geared up with a combustion engine that acts as a generator.
It stays unclear how a lot an X5 with a variety extender would price, although it’s more likely to be priced between the plug-in hybrid and the totally electrical iX5.
