It’s time for an AMG SL showdown!! We’ve got our hands on the all-new Mercedes-AMG SL 55, and it’s about to go head-to-head over the quarter-mile against a classic SL 55 from 2004! So which is better? Well, let’s check out the stats! The old SL rolls up with a 5.5-litre supercharged V8 under the bonnet that can normally deliver 490hp and 700Nm. However, the one we’ve got our hands on has been tuned, and can now deliver 625hp! It s equipped with RWD, and it weighs in at 1,885kg. As for the new SL, the supercharged V8 has been swapped for a 4-litre twin-turbo V8. This can put down 476hp and 700Nm, which means it’s down on power compared to the tuned SL. However, it has one key advantage… It comes with AWD! So what do you think, will it be a clean sweep for the new SL? And more importantly, will it show that it’s worth the eye-watering £147,000 price tag?! There’s only one way to find out for sure… LET’S RACE!Mat's sports car deal: Sell your car with carwow: Tuned AMG C63 Black v Tuned BMW M3:
