2018 Mercedes GLC 63S VS 2018 BMW X5

2018 Mercedes GLC 63S:
A Small CUV with 469 HP of V-8 Fury: Mercedes-Benz’s thinly sliced SUV pie is getting divvied up yet again, and the latest addition to the lineup could be one of the most delicious pieces yet. AMG’s latest creation, the V-8–powered GLC63 4MATIC, stuffs the glorious hand-built 4.0-liter V-8 engine into the engine bay of the compact GLC-class crossover and its GLC coupe sibling (covered separately). With muscular looks, comprehensive chassis upgrades, and what we expect to be a burly soundtrack from the thundering V-8, the GLC63 looks to be mighty enticing. Leave it to AMG to pack so much power—469 horsepower and 479 lb-ft of torque—into such a small vehicle. Among the GLC’s competitors, only the Porsche Macan Turbo and the Alfa Romeo Stelvio Quadrifoglio top 400 horsepower, and V-8 engines are unheard of in this class. And what a V-8 it is: The twin-turbocharged 4.0-liter unit is found in nearly all AMG 63 models as well as the monstrous AMG GT sports car. Although the GLC63 will be limited to one performance tune (the pictured Euro-sped GLC63 S won’t be offered in the U.S.), even more grunt will be available in the GLC63 S coupe variant, which will offer an upgraded version of the V-8 with 503 horsepower and 516 lb-ft of torque. Mercedes is quoting a 3.9-second zero-to-60-mph run for the GLC63—and given our 4.5-second result for the GLC43, which is 107 horsepower less powerful, that number might prove to be an understatement. AMG’s familiar nine-speed automatic transmission, with a multiplate clutch that replaces a torque converter, comes standard, as does a performance-oriented 4MATIC+ all-wheel-drive system, which features a limited-slip rear differential that varies front-to-rear torque distribution on the fly.

2018 BMW X5:
The 2018 BMW X5 is a popular luxury crossover SUV available with seating for up to seven. It’s a strong overall package, albeit one that lacks some of the BMW verve of yore. We’ve rated it a 7.2 out of 10 based on its excellent real-world usability, strong engines, and varied lineup. (Read more about how we rate cars.) The X5 changes little for 2018, other than a sport-tuned version of its automatic transmission is now standard on almost all versions, and the German automaker has shuffled option packages to act more like trim levels. That means that the popular Premium package—which you’re likely to find on just about every X5 stocked on a dealer lot—now acts as a gateway to most individual options. There’s less configurability, but little lacking in this lineup. The X5 remains available with 3.0-liter turbo-6 or 4.4-liter twin-turbo V-8 gas engines, a 3.0-liter turbodiesel, and a plug-in hybrid variant that costs a lot for its limited 14-mile electric-only range. Rear-wheel drive is standard with the base gas engine. All-wheel drive is optional on the base X5 and standard elsewhere. All models use 8-speed automatic transmissions. Despite its chunky looks, there’s not a lot of off-road ability here—not that most buyers are likely to go mud-plugging. An X5 M model tops the lineup with a 567-horsepower version of the X5’s available V-8. With its track-tuned suspension, sports seats, and beefed up steering, it’s a reasonable facsimile of a high-riding sports wagon. It’s as absurd as its six-figure price tag suggests, but it is a lot cheaper than a Porsche Cayenne Turbo. A roomy interior with great room for five adults awaits buyers. For those who want a little more space, a third row is optional, but it’s not great. For occasional use, the third row is acceptable for kids and may be worth considering for carpooling families. The X5 lineup has scored exceptionally well in all crash-tests so far, but we don’t have a complete picture from the IIHS and can’t assign a score...
