TCC’s Bottom Line

Performance, plug-in, or pedestrian: there’s a 2018 Mercedes-Benz GLE for almost every luxury-SUV buyer.

The 2018 Porsche Cayenne is a richly appointed luxury SUV that earns its Porsche badge. It's one of few cars on the road that manage to feel special in standard or top trims, despite a $100,000 price difference.

TCC Likes

Wide palette of body styles, powertrains, trims
GLE Coupe, for the well-to-do contrarian
Powertrain choice abounds

Strong engines
Superlative handling for the big SUV
Lots of options to consider

TCC Dislikes

AMG = $$$
Not so fuel-efficient
Addled infotainment interface

Not particularly efficient with space inside
Base model isn’t really thrilling
Unbelievably expensive options
