When choosing between the BMW X1 and the Volkswagen Passat, the BMW X1 is the more suitable option. The BMW X1 is a compact luxury SUV, offering a blend of performance, comfort, and advanced technology. On the other hand, the Volkswagen Passat is a mid-size sedan known for its reliability and comfort but lacks the dynamic driving experience of the X1.

The BMW X1 excels in terms of performance, with a range of powerful engines available, including a 2.0-liter turbocharged four-cylinder that produces 255 horsepower. This engine provides smooth acceleration and responsive handling, making the X1 a joy to drive. In contrast, the Volkswagen Passat offers a more subdued driving experience, with its 1.8-liter turbocharged four-cylinder engine producing 190 horsepower. While the Passat is still a capable performer, it doesn't match the X1's dynamic capabilities.

In terms of technology, the BMW X1 is also superior. The X1 comes with a range of advanced features, including a 10.25-inch digital instrument cluster, a 10.7-inch touchscreen infotainment system, and a heads-up display. The Volkswagen Passat, while offering a similar level of technology, lacks some of the X1's high-end features.

According to Consumer Reports, the BMW X1 received a higher overall score than the Volkswagen Passat, with the X1 scoring 85 out of 100 compared to the Passat's 81. This reflects the X1's superior performance, comfort, and technology.

In conclusion, the BMW X1 is the better choice between the two vehicles. Its dynamic driving experience, advanced technology, and powerful engine make it a standout option in the compact luxury SUV segment.
