Whether to choose the 25i or 28i for the 2021 BMW X3 depends on the buyer's specific needs. The main difference between the two models lies in their powertrain performance. Below are the powertrain specifications for both models: 1. BMW X3 25i: The 25i model is equipped with a low-power version of the 2.0-liter turbocharged engine. This low-power 2.0-liter turbocharged engine delivers 184 horsepower and a maximum torque of 290 Nm. The engine's maximum power output is achieved between 5,000 and 6,500 rpm, while the peak torque range is from 1,350 to 4,250 rpm. This engine features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. 2. BMW X3 28i: The 28i model comes with a medium-power version of the 2.0-liter turbocharged engine. This medium-power 2.0-liter turbocharged engine produces 224 horsepower and a maximum torque of 310 Nm. The engine's maximum power output is achieved between 5,200 and 6,500 rpm, with peak torque available from 1,400 to 5,000 rpm. Similar to the 25i, this engine also incorporates direct fuel injection technology and uses an aluminum alloy cylinder head and block.
I've been driving for many years and I particularly love the sporty feel of BMW. I've test-driven both the 25i and 28i versions of the 2021 X3. The 25i is perfectly adequate for daily errands and school runs, with decent fuel efficiency at around 8 liters per 100km. But if you frequently drive on highways or mountain roads, the 28i is noticeably more enjoyable—it's over a second quicker in acceleration, has more direct throttle response, and feels effortless when climbing. Price-wise, the 28i costs about 20,000 RMB more, but I think the extra horsepower justifies the difference, especially when overtaking on highways—it gives you that extra confidence. Safety-wise, both are equally solid, no difference there. Overall, if your budget allows, go for the 28i—it adds a bit more fun to driving and delivers a more complete driving experience.
Our family consists of my spouse, our child, and myself. We drive an X3 mainly for its practicality and durability. The 2021 25i model is quite suitable—its power is more than enough for city driving, and it’s fuel-efficient in traffic, averaging around 8.5 liters per 100 km for me. The 28i offers a bit more punch with slightly stronger acceleration, but spending tens of thousands more isn’t really necessary, especially when the family budget is tight. The money saved could cover several years of insurance. Plus, the 25i is cheaper to maintain, with a simpler structure that’s less prone to issues. The space is identical in both, so no need to overthink it. My advice for family use is to go with the 25i—it’s cost-effective, economical, and easy to drive.
