Mercedes-Benz just launched the all new Mercedes E-Class, but it does not mean they will have a long holiday to celebrate the success. They are now working on a high-end variant for the new Mercedes E-Class. These 2017 Mercedes E63 AMG spy shots were captured while they are testing the new car in Spain. The new Mercedes E63 AMG will feature larger air intakes, a single bar grille, new side skirt, better braking system, rear spoiler and exhaust system with four tailpipes. The Mercedes E63 AMG is expected to use an improved 4.0-liter twin turbo V8 engine from AMG with a 4Matic system.
