Given the choice between being “spectacular” or “likeable,” is it enough to be the latter? We wonder after having driven Mercedes-Benz’s GLC 300 4MATIC premium-compact crossover. It’s an easy vehicle to like without its being outright spectacular.

Test Drive: 2020 Mercedes-Benz GLC 300
Our test vehicle was outfitted with the $400 Night Package, which adds a number of high-gloss black trim elements– including the roof rails, window trim, grille trim, and rear diffuser.

For 2020 the GLC-Class vehicles—a traditional wagon-body sport-ute and a four-door hatchback “coupe”—get subtly refreshed styling, an updated infotainment system, and a new 4-cylinder engine for the 300-level models. Otherwise, GLCs are very much like they have been since the model line bowed in 2016 as a derivative of the C-Class sedan platform.

The GLC 300 engine is still a turbocharged 2.0-liter job, but the new one is rated at 255 horsepower (a gain of 14 over the previous engine) and 273 lb-ft of torque. With that maximum torque arriving as soon as 1800 rpm and sticking around to 4000 revs, there’s a true liveliness to the vehicle. The 9-speed automatic transmission is smooth and responds well when required to kick down for acceleration. Clicking into “Sport” mode adds a pinch of extra accelerative spice to the sauce by delaying upshifts. Plus, the powerteam seems to live up to expectations for fuel consumption. The EPA projects a 300 4MATIC like the one Consumer Guide tested to average 21 mpg in city driving, 28 mpg on the highway, and 24 combined; this reviewer attained 22.1 mpg after a stint of 163 miles, 60 percent of which was in city-type operation.

The GLC 300’s cabin ambiance is suitably upscale, particularly with the numerous optional upgrades our test vehicle carried. Some of our testers weren’t big fans of the MBUX infotainment control interface, however.

Bestowed with a fully independent multilink suspension, the GLC 300 rides nicely, and it handles with ease. In “Sport+” it is perhaps a half shade tighter in steering and damping, but it’s all pretty much the same vehicle all the time. To this driver, the GLC was eminently likeable on the road, but not really stirring or engaging.

If anything did quicken his pulse, and not in a good way, it was the Mercedes-Benz User Experience infotainment controls. MBUX, as the manufacturer calls it, trades console dial control for a central touchpad. Graphics displayed on the 10.25-inch touchscreen are great, but working functions through the touchpad while driving will take time to master. Here’s one small example: To access a preset radio station requires dragging a finger over the pad until the display indicates you’ve reached the one you want—which diverts attention— then tapping to call it up. (A no-look thumb button on the steering wheel would be so much more convenient.) Even turning the radio off is a 2-step process. What looks like “on/off” button on console just summons a 2-choice prompt on the display screen, and then you press that to actually turn the radio off.

The $1620 Cranberry Red and Black leather upholstery livened up the interior ambiance of our test vehicle.

What is much easier to like is the interior room for people and things. There is decent headroom throughout. Legroom is quite good up front, and let’s say sufficient in back for two average-sized adults. (Three-across seating for grown-ups isn’t really possible.) Seats are comfortable; the optional leather upholstery in Cranberry Red and Black made them plush and attractive. Driver vision suffers at the rear corners, but isn’t bad to the front and sides.

The GLC’s cargo area isn’t as generous as many of its class rivals’, but it’s especially nicely finished. There’s 19.4 cubic feet of cargo space behind the GLC’s rear seats, which grows to 56.5 cu. ft. with the rear seats folded down.

Personal storage for front passengers relies on a capacious glove box, pretty roomy split-top console box, a covered console bin for cup holders and wireless charging/device inputs, and door pockets with bottle holders. Second-row storage consists of hard-sided pouches on the backs of the front seats, smaller door pockets/bottle holders, and a center armrest with pop-out cup holders and a shallow covered bin. With all seats up, there’s pretty good cargo space in back that loads at bumper-height, and there’s also lots of underfloor room. The 40/20/40 rear seats fold flat for a big expansion of load floor; remote releases in the cargo bay make this process easier.

The GLC 300 gets a new turbo 4-cylinder engine for 2020 that makes a bit more power than the previous one–255 horsepower instead of 241. The 18-inch wheels and tall-sidewall tires on our test vehicle contributed to its cushy ride.

What can be spectacular about the GLC 300 is its price. CG’s tester went from a believable starting price of $45,495 with delivery to an eye-popping final $60,575, though it had a list of options nearly as deep as the standard-equipment roster. For the lower number you’ll get dual-zone automatic climate control, keyless starting, wood interior trim, Bluetooth connectivity, connected services, Apple CarPlay/Android Auto smartphone compatibility, heated front seats, power liftgate, cargo cover, roof rails, rain-sensing windshield wipers, LED exterior lighting, and blind-spot assist. A highlight reel of the many things added, either singly or in option packages, includes the Graphite Grey Metallic paint, “MB-Tex” leatherette dash and upper-door covering, panoramic sunroof, 12.3-inch digital instrument cluster, wireless charging, a group of safety monitors and adaptive cruise control, navigation, and satellite radio. The takeaway is the individual buyer becomes the master of just how much luxury will be in his or her luxury vehicle. Note that a rear-wheel-drive GLC 300 costs $2000 less.

It’s a good bet that the AMG versions of the GLC, either the 43 with a 369-horsepower V6 or the 63 with a 469-horse V8, elicit a lot more passion for the vehicle among their owners. Meanwhile, the 300 is likeable—but if people like it to the point of wanting to buy one, then that is enough.

The Mercedes-Benz GLC 300 is a well-rounded premium compact crossover that offers a high level of customization, but all those options can really drive up the bottom-line price–to the tune of more than $16,000 on our test vehicle.
