Why has the new X3 discontinued the full-time four-wheel drive?
2 Answers
Here are the reasons why the BMW X3 does not use full-time four-wheel drive: 1. The BMW X3 has never used full-time four-wheel drive. 2. BMW has always publicly stated that the "xDrive" system in the X3 refers to an intelligent all-wheel-drive system, which is a smart four-wheel-drive system developed by BMW. However, it has not explicitly clarified whether this system is full-time four-wheel drive or on-demand four-wheel drive. 3. Since the system previously used a 40:60 front-to-rear power distribution, consumers were more inclined to refer to it as full-time four-wheel drive. Therefore, the BMW X3 has always used on-demand four-wheel drive.
I noticed the new BMW X3 has discontinued the full-time four-wheel drive system mainly to improve fuel efficiency and environmental performance. As a frequent driver, I understand that full-time 4WD constantly powers all four wheels during normal driving, which increases mechanical resistance and weight, leading to higher fuel consumption. Now, with the shift to an on-demand AWD system, the vehicle primarily operates in front-wheel drive mode on dry roads, only switching to all-wheel drive automatically when slipping or in rainy/snowy conditions, saving significant fuel. BMW is likely responding to global emission reduction requirements, such as the EU's new standards, while also helping users save hundreds in annual fuel costs. I think this change is very sensible, especially for urban commuting or highway driving—it's more eco-friendly by reducing carbon emissions, aligning with the broader electrification and hybrid trends, making the X3 more appealing to sustainability-conscious consumers in the competitive market.
