Google Rank

Highs Awesome power and performance, sexy, swoopy design, futuristic interior.
Lows Complicated infotainment controls, much more expensive than an AMG E53, less cargo space than a Porsche Panamera.
Verdict An inspired combination of design, performance, and practicality.

All new just last year, the scintillating 2020 Mercedes-AMG GT53 and GT63 are the German brand's latest versions of a "four-door coupe." Although its name seems to imply that these sexy four-door, four-seat hatchback sedans are based on the GT coupe, Mercedes has actually used the bones of the E-class. The cars' high-performance hardware and powerful engines, however, are pure AMG. All GT four-doors get all-wheel drive, electronically adjustable dampers, sport seats, and big horsepower, while the GT63 and GT63 S models pack twin-turbo V-8s for neck-snapping acceleration.

What's New for 2020?
Since the AMG GT53, GT63, and GT63 S were all-new models for 2019, not much has changed for 2020. However, Mercedes has made AMG illuminated doorsills standard on the GT53 and the AMG performance exhaust standard on the GT63. There's also a new carbon-fiber roof option on the GT63 S and a new fixed panoramic roof option for all three variants.

Pricing and Which One to Buy
GT53: $100,945
GT63: $141,245
GT63 S: $162,195

Although there isn't a dud in this family of fast four-door hatchbacks, the most potent GT63 S model delivers the comfort and practicality of a family-friendly hatchback sedan with the intense power and performance of a supercar. AMG cranks up its twin-turbocharged V-8 to 630 horsepower, which drops its claimed zero-to-60 mph time to just 3.1 seconds and adds larger 20-inch wheels and tires for additional grip. It's also the only variant to feature a standard Drift Mode within its all-wheel-drive system. Just push the button, and the GT63 S becomes rear-wheel drive for more spirited track driving and high-school-style burnouts and power slides.

Engine, Transmission, and Performance
Under the hood of the 2020 GT53 is a snarling inline-six-cylinder engine that features a supercharger, a turbocharger, an intercooler, and a small electric motor. From a stop, the electric motor and supercharger fill in the brief lapse before the turbo is fully committed. The 3.0-liter, which packs a combined 429 horsepower, snaps necks whenever you touch the accelerator. In our testing of the GT53, which features a conventional nine-speed automatic transmission, accelerated to 60 mph in 4.1 seconds and its sport-tuned suspension delivers flat, responsive cornering and sports-car levels of grip. The GT63 and GT63 S are powered by a thunderous 4.0-liter V-8. The engine is a technological tour de force with dry-sump oiling, direct injection, and two turbochargers mounted in its V. It's rated to produce 577 horsepower in the GT63, but it's cranked up to 630 horsepower in the GT63 S. These models also get a dual-clutch nine-speed automatic transmission and air suspension. AMG says the GT63 hits 60 mph in just 3.3 seconds, while in our testing, the GT63 S needed just 2.9 seconds. That's as quick as a Porsche Panamera Turbo.

Fuel Economy and Real-World MPG

With such extreme performance, it's no surprise the Mercedes-AMG GT53 and GT63 are thirsty, but their EPA fuel-economy estimates aren't as dire as you might expect. The GT53 model is rated 19/24 mpg city/highway. Those numbers drop to 15/20 mpg for the more powerful GT63 model with a V-8. For comparison, the 2020 Porsche Panamera Turbo, which is powered by a twin-turbo 4.0-liter V-8 with 550 horsepower, is rated 18/25 mpg city/highway.

Interior, Comfort, and Cargo
While much of the 2020 GT coupe's interior is shared with the other four-door coupe from Mercedes, the CLS, the large console between its seats appears to have been pulled from the GT sports car. It's a bit intrusive but makes for a sporty cockpit feel. The interior design overall is futuristic and visually exciting, but some of its ergonomics can take some getting used to. This is also a four-seater, which may be an issue for some families. Aggressively bolstered sport seats are standard and comfortable, while a fat and flat-bottomed steering wheel, aluminum trim, and digital gauge cluster fit the sedan's high-performance mission. Build quality is exceptional, and the materials are in line with AMG's pricing. This is a hatchback, and the GT coupe's rear seats do fold down to increase cargo space. With its rear seats in use, there's 12.7 cubic feet of space. That's plenty for most, but the Porsche Panamera offers more.

Infotainment and Connectivity
Unfortunately, the AMG's infotainment system, while impressively capable, is complicated and can be frustrating to use.
