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.
