The Car Connection's Take

7.7
TCC’s Bottom Line
The 2018 Mercedes-Benz GLS takes an old-school tack to modern-SUV design, and it works. The 2018 Tesla Model X is the only all-electric SUV you can buy this year. It’s swift, pleasant to travel in, and relatively practical, save for its somewhat silly doors.
