The Car Connection's Take
TCC Rating
7.0
6.8
TCC’s Bottom Line
The 2018 BMW X3 ventures into M territory, but doesn’t lose sight of its SUV duties. The 2018 BMW X4 takes today’s trend toward swoopier SUVs and packages it with a roundel up front. It’s entertaining and a looker, but not all that practical.
