TCC’s Bottom Line

The 2018 BMW X3 ventures into M territory, but doesn’t lose sight of its SUV duties.

The 2018 Mercedes-Benz GLC-Class captivates crossover types with its lush cabin and its plush ride; there’s AMG power on tap if you must.

TCC Likes

Nimble, sedan-like handling
Excellent interior space and storage
Great turbo-6 powertrain

Cabinet-grade interior (agency or furniture)

TCC Dislikes

Base 6.5-inch infotainment display
Forward-collision warnings an option
World’s most expensive Apple CarPlay

Expensive safety options
It’s not a Coupe, it’s just less useful
Numb steering (GLC 300)
