The BMW X6 M is available in only one feature-loaded trim, so there's not much to recommend. This is a BMW, however, so there are several other option boxes you can check, and the most appealing might be the Executive package. Highlights include cooled front seats, heated rear seats, wireless smartphone charging, a Wi-Fi hotspot, and a host of driver safety aids (including blind-spot monitoring, lane departure warning, surround-view cameras). It's a pricey package, but it's packed with details that will make the X6 M that much more enjoyable.
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, passengers Gas pedal sometimes responds slowly in low-speed 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.
The BMW X6 M is a large SUV with a coupe body that offers sports car handling with all the practicality of a big 4×4.Driving is where the X6 M not only impresses but even amazes – there is endless grip and you rarely feel the 2.3-tonne weight of the car.
Pros Astonishingly fast High-quality interior Great engine
Cons Little bit of road noise A tad firm Not cheap
The Jeep Grand Cherokee Trackhawk is the third Fiat Chrysler vehicle to have the unhinged supercharged V-8 stuffed under its hood, and it’s the quiet Hellcat next door. Not literally, of course—have you heard a blown Hemi V-8 at full whack?—but with standard all-wheel drive mitigating the engine’s tire-spinning proclivities, plus its under-the-radar looks, the Trackhawk can at least pass for an upstanding citizen. With more traction than any Hellcat yet, the Trackhawk has quite a lot of poke despite its pork—the engine adds 259 pounds over the already heavy 475-hp Grand Cherokee SRT. Nonetheless, Jeep claims it can reach 60 mph in 3.5 seconds. That time is on par with the nearly 1000-pounds-lighter, automatic-equipped Dodge Hellcats we’ve tested. (The quickest was the Charger, which reached 60 mph in 3.4 seconds.) Per Jeep, the quarter-mile is expected to fly by in 11.6 seconds (at 116 mph!), and, with no electronic governor, the Trackhawk is said to surrender to atmospheric resistance at 180 mph.
