2021 BMW X3 adds some desirable standard equipment

The BMW X3's continued success is unquestionably due to its combination of qualities. Not only is it among the most upscale and enjoyable of compact luxury SUVs, but it's also comfortable, spacious, and practical, making it a very talented and desirable all-rounder. BMW offers the 2021 X3 in a number of models, including the plug-in hybrid xDrive30e and, at the other end of the range, the high-performance X3 M. The plug-in allows some electric-only motoring, but it typically comes at a hefty price point and its EPA-estimated fuel economy isn't overly impressive beyond those short-run battery-powered trips. The X3 M fulfills a different aim: It's a wickedly fast yet still very capable premium compact SUV. The thing is, the X3 M's power comes with a stiff suspension that makes it uncomfortable on all but the smoothest of roads.

In the middle, the rear-wheel-drive sDrive30i, the all-wheel-drive xDrive30i, and the M40i have all the X3's strengths without the compromises found on opposite ends of the lineup. Even the entry-level 248-hp 2.0-liter turbo engine in the 30i models provides good performance, backed with solid EPA-estimated fuel economy. The M40i raises the stakes a bit, adding more power via a turbocharged six-cylinder 3.0-liter engine for very enjoyable, quick driving. It might prove the sweet spot, because it comes with equipment that you'd have to add as options to the 30i models, and it benefits from the sharper M Sport styling. Also of note for 2021, the X3 adds some standard safety features and Android Auto™ capability joins the existing Apple CarPlay®.
