The fourth-generation BMW X3 has been unveiled, showcasing a drastically altered exterior design, a fully revised interior, and a much improved chassis—all while maintaining gasoline and diesel engine options.

Next year, a completely electric X3 idea, based on a completely new architecture, will make its debut. It was teased by the avant-garde Neue Klasse X concept. However, this most recent model—which will go on sale by year's end—evolved from the 2017 "G01" vehicle.

The rear-biased CLAR chassis is still used by the fourth generation of BMW's best-selling vehicle, which had 350,000 worldwide sales last year. To achieve "an even broader range of driving characteristics and added ride comfort," project head Martin Delitz recently told Autocar, it has undergone a comprehensive chassis rework.

For example, the track has been expanded by 23mm, tougher roll bar mounts have been placed up front, and the rear axle mounts have been reinforced for more stability. The suspension has been overhauled at either end. The new belt-driven setup has replaced the dual-pinion steering system, although customers may still opt to upgrade the passive dampers that come standard with active ones.

The China-made iX3 has been discontinued from the lineup in favor of an unrelated electric-only option that will launch next year. The X3, however, retains its diesel engine in addition to choices for gasoline and plug-in hybrid vehicles, in contrast to the newly redesigned 1 Series, 2 Series, 3 Series, and 4 Series.

Outside, the X3 has undergone a significant overhaul in keeping with BMW's daring new design language. These are the most noticeable modifications, though. The grille is now more noticeable and has the possibility to light up, the bonnet has been elevated, and each end has sleek new light designs.

Although it is a little bit broader and longer than the previous model, BMW claims that the roof has been reduced for a "more sporty silhouette."

Inside, the X3 has undergone a total redesign. With a wraparound digital display at its center, the minimalist dashboard houses BMW's most recent iDrive system, which can be operated via a rotary knob on the center console or by utilizing the touchscreen. Utilizing a new haptic "Interaction Bar" taken from the 7 Series, the temperature control is changed.

The X3's cabin material quality has also received a lot of attention, and BMW emphasizes the added utility provided by a 20-liter increase in cargo space.
