This is the showdown we’ve been waiting for. Two of Germany’s fastest sedans launched on the world’s most famous highway. Our friends at AutoTopNL wanted to see how fast both cars reached 180 mph, so here is the Mercedes-AMG GT 63 S versus a Porsche Panamera Turbo S on the Autobahn.
Representing Affalterbach is the most powerful AMG sedan. It is rated at 639 horsepower and 627 lb-ft of torque. The Panamera Turbo S offers 671 horsepower and also makes 627 lb-ft of torque. Having identical torque numbers isn’t a coincidence. It translates to 850 Newton-Meters in metric, and that is a figure that many exotic cars use as a benchmark. Both cars have 4.0L V8 engines and AWD. Tell us who wins on styling, interior layout and exhaust sound in the comments below and stay with us for more wild Autobahn action.
