585HP Mercedes-AMG SL63 vs Mercedes-AMG S63 Coupe vs Liberty Walk GTR Drag & Track by turboandstance - September 6, 2018 This time I have filmed the new 585HP Mercedes-Benz SL63 AMG (R231) in action on the drag strip. It did some drag races between other cars like the Mercedes-AMG S63 AMG, the LibertyWalk LB Performance Nissan GT-R and a 557 HP Mercedes-AMG GLE63 AMG! The new SL63 AMG is fitted with an 5.5 liter Bi-Turbo V8 engine that produces 585HP and goed from 0-100 km/h in just 4.0 seconds. Leave a comment
