The GT 63 is available in two flavors: standard and S. Both models use the same 4.0-liter biturbo V8 mated to a nine-speed automatic transmission sending the power to all four wheels. The base model’s power output is 577 hp, while the S gets 630 hp.
Both cars are equipped with adaptive air suspension, rear-wheel steering, launch control, dual 12.3-inch screens, MBUX, dual-zone climate control, 64-color ambient lighting system, power-adjustable heated seats, and a 14-speaker Burmester sound system.
Being the more dynamic of the two, the S comes with Race and Drift modes, which is optional on the base model, but other additions include dynamic engine mounts and the AMG Drive Unit.
The base Mercedes AMG GT 63 carries an MSRP of $140,600, while the more powerful 63 S retails for $161,900. This excludes the destination fee of $1,050. It seems like a lot of money, but it's reasonable compared to the Porsche Panamera. The Turbo S model retails for $179,095 and is not as fast as the 63 S. For around the same money as the standard model, Porsche will sell you a Panamera GTS that also uses a 4.0-liter twin-turbo V8, but with only 473 hp and 457 lb-ft of torque.
For added practicality, opt for the Executive Rear Seat Package. It costs $3,550 and adds heated and cooled cupholders, tri-zone climate control, two USB charge ports, and a touchscreen display to control the infotainment system. This also allows you to fold the rear seats flat for more cargo capacity. The Driver Assistance Package adds all of the advanced driver assistance features, including adaptive cruise control, active steering assist, and evasive steering assist, to name just a few. Keen drivers have to add the AMG Dynamic Plus Package to the base model ($3,000) consisting of dynamic engine and transmission mounts, Race and Drift modes, and yellow brake calipers. Notable standalone options include AMG Performance Seats for $2,500 and the $4,550 Burmester 3D surround-sound system.
The GT 63 S may sound more appealing, but it's for sale at $20,000 more. For that, you get more power and torque, larger alloy wheels, dynamic engine and transmission mounts, Race and Drift modes, the steering-wheel-mounted AMG Drive Unit, and a 0-60 mph time that's 0.2 seconds faster. However, aside from the power, the Dynamic Plus Package is available on the base model for just $3,000 and the AMG Drive Unit costs just $400. There's hardly any difference in top speed, not that you're going to be doing it anyway. We'd save that $20,000 and spend it on all the lovely optional systems mentioned above instead.
