What is the chassis analysis of the BMW X3?

The front suspension uses BMW's common double-joint spring strut, while the rear suspension employs a multi-link independent suspension. Below are the detailed introductions of the relevant content: Introduction: The new BMW X3 features a front suspension with BMW's typical double-joint spring strut and a rear suspension with a multi-link independent suspension. The front suspension maintains the same structure as the previous generation but uses more robust materials. Although the rear suspension remains a five-link design like the previous generation, the design and layout of the control arms have been altered. Additionally, the new-generation X3 has a wheelbase extended by 54mm compared to the previous generation. Drive: BMW's new rear-wheel-drive/four-wheel-drive platform is called the CLAR platform. This platform allows the use of a hybrid of steel, aluminum, and carbon fiber materials for the body and was designed from the outset to accommodate plug-in hybrid and pure electric systems. The CLAR platform was first applied in the new-generation 7 Series and has since been widely adopted across BMW's lineup. Except for front-wheel-drive models like the X1, most of the new-generation BMW models utilize this platform.
Speaking of the BMW X3's chassis, I've driven it on mountain roads and over gravel, and it feels really solid. The front wheels use a double-joint spring strut suspension, providing exceptional tire grip during cornering, with the steering wheel responding precisely. The rear five-link design effectively absorbs bumps, so driving over manhole covers doesn't cause any jarring. The ground clearance is higher than sedans, and the chassis comes with plastic underbody protection, so rough roads won't scrape the oil pan. However, don't treat it as a hardcore off-roader—I once bottomed out on a dirt slope due to limited anti-roll bar travel. But its on-road performance is impeccable, with lane changes at high speeds feeling glued to the ground.
