2024 BMW X1 M35i

The X1 and GLB are two of our top extra-small luxury SUVs. Both rivals are similar in price, size and power. The GLB boasts excellent ride quality, comfortable seats and class-leading tech. The Mercedes also sports a distinctive boxy design, something most of its rivals lack, and its available third row is rare for an SUV of its size. On the downside, it provides less cargo space than the X1 and isn't as fuel-efficient.

The Q3's attractive interior and superb tech plus a lower starting price make it an alluring alternative. And like the X1, it comes standard with all-wheel drive. However, the Audi is less powerful and less efficient, and it provides less passenger and cargo space. The Q3 is a solid choice but is outperformed by the newer X1 in many ways. Of note, though, options can quickly inflate the X1's price and it has a rough engine stop-start system.

The XC40 sports a distinctive design and boasts an elegant interior that is well built but not as luxurious as the X1's. It also offers less cargo space than the BMW and has a firm ride. On the plus side, it comes equipped with a large package of advanced driver aids and an excellent Google-based infotainment system that has Google Maps and gives you access to your Google account. As for price, the Volvo starts higher, but adding options to the X1 can easily make it more expensive.
