00:00 Specification Mercedes-AMG SL63 & SL43
00:17 Mercedes-AMG SL 63 4Matic+ V8 engine sound: comfort and sport+
00:26 Mercedes-AMG SL63 exhaust sound: comfort and sport+
01:03 Mercedes-AMG SL 43 engine sound: comfort and sport+
01:31 Mercedes-AMG SL43 exhaust sound: comfort and sport+
02:00 Mercedes-AMG SL 43 acceleration (0-60 mph and 0-100 km/h time)
02:24 Mercedes-AMG SL 63 4Matic+ acceleration (0-60 mph and 0-100 km/h time)

Mercedes-AMG SL 43 achieved not the best acceleration time. The car started to move a little bit (around 30-40 cm) just after releasing the brake pedal but without hard acceleration. I had to include it to whole acceleration time. I observed such behavior with ESC ON, Sport and Off.
