BMW X3 and X5 differ in vehicle size, wheelbase, luggage compartment volume, and fuel tank capacity. Dimensions of BMW X3: The model dimensions of the X3 are length 4648mm, width 1881mm, height 1661mm, with a wheelbase of 2810mm and a fuel tank capacity of 67L. Dimensions of BMW X5: The model dimensions of the X5 are length 4909mm, width 1938mm, height 1772mm, with a wheelbase of 2933mm, a luggage compartment volume ranging from 650 to 1780L, and a fuel tank capacity of 85L.
I've always driven BMWs, and the main differences between the X3 and X5 are size and space. The X3 is a mid-size SUV, about 4.7 meters long, with a compact interior that's suitable for daily city commuting and young families—for example, it's sufficient for school runs, but the trunk can be a bit tight for large luggage. The X5 is a full-size SUV, over 5 meters long, offering much more spacious interiors with ample legroom in the back seats and a trunk that easily accommodates ski gear or camping equipment, making family trips more comfortable. In terms of driving feel, the X3 has a lighter steering wheel and a smaller turning radius, making it more agile in narrow alleys; the X5 is more stable and stately, ideal for long highway drives, though parking can be challenging. My X3 is more fuel-efficient for city driving, averaging about 8 liters per 100 km; the X5 consumes more, over 9 liters. If budget is a concern, the X3 offers better value for money, with a lower upfront cost by tens of thousands, making it highly practical for families.
In terms of driving performance, there are notable differences between the X3 and X5. After multiple test drives, I found that the X3, equipped with a base 2.0T turbocharged engine, delivers linear power output, quick acceleration, and excellent maneuverability in city traffic, achieving 0-100 km/h in under 7 seconds—ideal for daily commuting. The X5 offers multiple engine options, such as a 3.0T or V8, providing stronger power and completing the 0-100 km/h sprint in 6 seconds, making highway overtaking effortless. Its steering feedback is more substantial, leaning towards comfort-oriented handling, though its heavier body results in noticeable body roll during turns. However, it offers better grip in wet conditions. The suspension systems also differ: the X3 has a sportier setup with more pronounced road feedback on bumpy surfaces, while the X5's air suspension is softer, ensuring a fatigue-free experience on long drives. Fuel efficiency-wise, the X3 is more economical at around 8L/100km, whereas the X5 exceeds 10L/100km and requires pricier 95-octane fuel. In summary, the X5 suits those prioritizing luxury driving, while the X3 emphasizes practicality.
