Our First Official Look at the New BMW X3

The outgoing X3 was BMW's best-seller with 350,000 units delivered in 2023. Despite being debuting in 2017, the luxury crossover was still more popular than the newer 3 Series Sedan. But the German premium brand isn't resting on its laurels—a new X3 is just weeks away from being revealed.

But first, a little preview. Images of camouflaged prototypes show the plug-in hybrid and M Performance derivatives. The hot one features a quad exhaust system, a trait previously reserved for the actual M cars. The X1 M35i and X2 M35i were the first M Lite models to adopt the more aggressive setup, and now the larger not-quite X3 M is following suit.

The high-performance X3 is likely moving away from its "M40i" designation to make way for "M50." Yes, without the "i" at the end. Rumor has it the posh crossover will be BMW's first gasoline model to drop the last letter, which for decades has referenced fuel injection. However, the diesels are retaining the "d" while the plug-in hybrids are keeping the "e."

Speaking of the electrified model, it won't be coming to the United States, at least not initially. That's disappointing since BMW says the new X3 (xDrive30e?) will have an upgraded battery with more usable energy for extra electric range.

Known internally by its "G45" codename, the 2025 BMW X3 hides a sleeker body underneath that swirly camouflage. The Bavarian marque has lowered the drag coefficient from 0.29 to 0.27 to improve fuel efficiency. It has a wider track compared to the outgoing "G01" generation, along with a reduced lift at the rear axle. The engineers were able to increase rigidity and adopt upgraded anti-roll bars for a more engaging ride, without negatively impacting ride comfort.

At an additional cost, the new X3 will be offered with an optional adaptive chassis featuring electronically controlled shock absorbers. Other changes include a more direct steering ratio for greater comfort and the latest in safety and driver assistance technology. BMW is confident the revamped X3 will pass all Euro NCAP crash tests with flying colors.

Expect a simplified dashboard layout with only a few conventional buttons. You’ll be accessing most functions through the touchscreen, as
