I have to rethink everything I’ve said over the years about the word “coupe.” I’m a traditionalist, and cling to the definition “a two-door hardtop car.” In my head, I picture a 1969 Chevy Nova two-door notchback – that’s my Platonic ideal of a coupe. The four-door version is a sedan. In my head, both of these cars are brown, by the way.

Mercedes-Benz began to tinker with the word “coupe” when it brought the 2004 CLS-Class. It was a four-door sedan with coupe-like styling, and it was gorgeous. And Mercedes called it a coupe, despite the fact that it was empirically a sedan. The CLS-Class caught on, and spawned a flock of coupe-styled four doors, so it wasn’t a big surprise when the coupe-styling craze jumped across to SUVs, notably first on the BMW X6. Coupe-like styling gave the X6 a visual boost over the X5, but actually reduced the utility of the utility vehicle. Still, BMW did it again with the X4, a four-door liftback SUV that they call “the Sports Activity Coupe.” I shake my old man fist at the X4, and insist that it turn down its loud music and gets off my lawn.

Now, I may have to eat my words. I spent a week test-driving the 2020 Mercedes-AMG GLC 63 S Coupe, and I fell in love. I no longer care whether they call it a coupe, an SUV, or a phaeton. Call it whatever you like – I call it fantastic.

As with all AMG vehicles, it all starts with the engine. This one gets a twin-turbocharged 4.0-liter V8 that’s rated to produce 503 hp and 516 lb-ft of torque, and uses an AMG Speedshift MCT nine-speed automatic transmission. The engine sings its siren song through a perfectly tuned exhaust, delivering a throaty note that rumbles in the pit of your stomach. The transmission can be operated manually via paddle shifters, or automatically, where it does a great job. The power comes on in a rush, and just keeps coming. Mercedes states a 0-60 mph time of 3.6 seconds, and top speed is quoted at 174 mph (electronically limited). 4MATIC all-wheel drive is standard.

Six dynamic driving modes are available in a new suite called AMG Dynamics. The modes (Slippery, Comfort, Sport, Sport+, Individual and Race) select parameters for throttle response, transmission behavior, steering feel, suspension settings, all-wheel drive torque distribution, locking differential action, and stability control – in other words, just about every aspect of driving. Cruising around, I tended to leave the Coupe in Comfort. When I wanted to romp a bit, I switched to Sport+, which stiffened up the ride and steering substantially, and put the Coupe on its toes – a real jolt of caffeine. If I had more time with the car, I would have invested time in dialing in an Individual setting for my favorite roads.

GLC’s interior is elegantly tailored. It has a subtle mix of materials, and uses carbon fiber to great effect, trimming it with polished metal and accenting with piano black. The dash is simple, sturdy, and perfect – one of my favorites. The landscape-oriented 10.25-inch infotainment screen sits above the center stack, close to the driver’s line of vision, which is great. It’s loaded with a new MBUX infotainment system, which is easy to navigate. The information is spread across the big screen, and supplemented or echoed in the 12.3-inch instrument cluster above the steering wheel. A head-up display is available ($1,100), and would be a smart addition for the safety-minded driver. I’m a big fan.

Outside, I love the lines of the Coupe. I have trouble thinking of it as an SUV, because it really doesn’t have the stance or proportions that I have come to expect of an SUV. It’s somewhere between a fastback and an SUV. If you’re looking for a vehicle that maximizes cargo capacity, this is not the one for you. But, if you need a bit more usable interior room than a traditional sedan, and still want a sleek profile and a sporty-looking vehicle, the GLC delivers. It’s athletic and taut, and really quite gorgeous, especially with Mercedes-AMG-level fit-and-finish.

All this beauty comes at a price. The base price for the 2020 Mercedes-AMG GLC 63 S Coupe is $84,100. My test vehicle with options came with an as-tested price of $96,425. Compare this to a base Mercedes-Benz GLC Coupe, which starts at $50,000, and it’s a little bit of a jolt.

You should also compare the GLC 63 S to the Porsche Macan, BMW X4, Acura RDX, Infiniti QX60 and Land Rover Range Rover Velar before making a decision.

I’ll be the one over here eating my words, and scratching out the definition of “coupe” in my dictionary.
