Mercedes-AMG GT 63 4-Door the Nürburgring’s Quickest Executive Car

The 2021 Porsche Panamera Turbo S‘s reign as the fastest executive car around the Nürburgring is over, as Mercedes-AMG reclaims the crown with its 2021 GT 63 S 4-Door. While the three-pointed star’s slinky sedan continues to rely on the same 630-hp twin-turbocharged 4.0-liter V-8 as before, the top-of-the-line trim benefits from a handful of chassis and suspension tweaks for the new model year, the combination of which helped the mighty Mercedes achieve a lap time of seven minutes and 27.8 seconds around the nearly 13-mile long track. That’s approximately two seconds quicker than the time logged by the 620-hp Panamera Turbo S, which knocked the GT 63 S 4-Door from the podium position earlier in the year.

In order to achieve this time, the GT 63 S 4-Door that Mercedes brought to the famed German track was equipped with optionally available equipment such as a set of sticky Michelin Pilot Sport Cup 2 tires and the AMG Aerodynamics package. The latter item adds a more pronounced front splitter, front and rear canards (little winglets), a deeper diffuser, and a fixed rear wing that offers up to 66 pounds of extra downforce relative to that of the standard unit. 

The 2021 Mercedes-AMG GT 4-Door starts at $90,950 for the six-cylinder 43 model. Opting for the top-of-the-line, eight-cylinder GT 63 S 4-Door raises the cost of entry to $162,950. So, if you absolutely must have the quickest executive sedan around the ‘Ring, come and get it—provided, of course Porsche doesn’t answer right back with a new time of its own.
