Comparison - Mercedes-Benz S-Class S450 4Matic 2019 - vs - BMW X6 M AWD 2019

BMW's Active Driving Assistant is standard.Apple CarPlay is standard but on a subscription basis.Is the 2019 BMW X6 M a gigantic sports car or an ultra-sporty luxury SUV? The answer is "both" but also "neither." It's an automotive curio that exists outside typical car and SUV segments and defies traditional car-buying advice. But for those who do "get it," the X6 M won't disappoint.

PROS
Performance is astonishing for an SUV
High-quality interior packed with features
Seats are comfortable and supportive

CONS
Distinctive exterior design limits rear-seat room and cargo space
Sporty suspension may feel too firm for some drivers and passengers
Power delivery can feel overcaffeinated in regular driving

The X6 M is a style item: it has sleek lines, a plush interior, and a coveted badge on the hood. It’s also stunningly quick and handles more like a sports car than anything that weighs 5000 pounds has any right to. It’s powered by a 567-hp twin-turbo V-8. An eight-speed automatic and all-wheel drive are standard, and up to 100 percent of torque can be routed to either the front or rear wheels, depending on driving conditions. It’s less practical than the boxy X5 M, but it’ll turn more heads.

Pros
Blistering performance,
commanding seating position.

Cons
Harsh ride,
constricted cargo space.
